Therefore, an RDMA (Remote Direct Memory Access) technology is proposed, which is a Direct Memory Access technology and can directly transmit data from a Memory of one server to another server without intervention of operating systems of both parties and causing any influence on the operating systems. RDMA can be understood simply as: by using hardware and network technology, the network card of the server 1 can directly read and write the memory of the server 2, and finally the effects of high bandwidth, low delay and low resource utilization rate are achieved, and the application program does not need to participate in the data transmission process, and only needs to specify the memory read-write address, start transmission and wait for the completion of the transmission.
The session information is an important parameter of the RDMA technology, and the network connection state and the activity degree of network flow can be analyzed by collecting the session information, so that the functions of helping to position network hotspots, assisting in troubleshooting and the like are achieved.

Detailed Description
The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein is meant to encompass any and all possible combinations of one or more of the associated listed items.
It should be understood that although the terms first, second, third, etc. may be used in the embodiments of the present application to describe various information, the information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present application. Depending on the context, moreover, the word "if" as used may be interpreted as "at … …" or "when … …" or "in response to a determination".
The embodiment of the application provides a session information acquisition method, which can be applied to a server, wherein the server can acquire data from another server by adopting an RDMA (remote direct memory access) technology, the RDMA technology is a direct memory access technology, the data can be directly transmitted from a memory of one server to another server, the intervention of operating systems of two parties is not needed, the influence on the operating systems is avoided, zero copy and kernel bypass can be realized through hardware, the participation of a CPU (central processing unit) is not needed, and high-performance data access can be provided.
In one example, the server may include, but is not limited to: the device comprises a network card driving module and a session information acquisition module. The network card driver module may be a driver (referred to as a device driver) for implementing communication between the operating system and the hardware device, and is equivalent to an interface of the hardware device, and the operating system can only control the operation of the hardware device through the driver. The session information acquisition module is used for acquiring session information and providing the session information for the upper layer application, so that the upper layer application analyzes the network connection state and the activity degree of network flow according to the session information, and the functions of helping to position network hotspots, assisting in troubleshooting and the like are achieved.
Referring to fig. 1A, which is a schematic view of an application scenario in the embodiment of the present application, a server may include, but is not limited to: the device comprises a network card driving module, a session information acquisition module, an application programming interface kernel module and a connection management interface kernel module. The application programming interface can be Verbs, and the Verbs are the bottom application programming interface defined by the RDMA technology and can provide the most basic management and transmission interface; the application programming interface kernel module is a kernel module for realizing the application programming interface function and can be controlled by an application program. In addition, the connection management interface kernel module can be rdmacm, and the rdmacm is a connection management interface defined by the RDMA technology, and can provide management interfaces for creating and destroying connections; the connection management interface kernel module is a kernel module for realizing the function of the connection management interface and can be controlled by an application program.
Referring to fig. 1B, the connection management interface kernel module may record session information of all sessions established by the application program through the connection management interface, and the connection management interface kernel module may provide a query interface to the session information collection module. Further, the session information collection module may collect the session information from the connection management interface kernel module periodically, for example, once every 1 minute, by accessing the query interface periodically.
However, the above-described method has the following problems: the acquisition period is not easy to determine and the session information is omitted. For example, if the collection period is too short, frequent collection of session information may increase the processing pressure of the server, increase the load of the server, and even affect the processing of normal services. If the acquisition period is too large, the session information is missed; for example, the session information collection module collects session information at time a and time B, and if a piece of session information is created after time a and deleted before time B, the session information collection module cannot collect the session information, so that session information between two collection operations is omitted.
In addition, the session information collection module can only collect session information from the connection management interface kernel module, and cannot collect all session information. For example, if an application program does not use the connection management interface to establish a session, but uses the application programming interface to establish a session, session information of the session is recorded in the application programming interface kernel module, and since the application programming interface kernel module does not provide a query interface to the session information collection module, the session information collection module cannot collect the session information from the application programming interface kernel module.
Different from the above manner, referring to fig. 1C, all session information (for example, without limitation, session information generated when a session is established using a connection management interface, session information generated when a session is established using an application programming interface, and the like) may be acquired by the network card driver module, and may be stored in the first storage medium. Moreover, when the session information changes each time, the network card driving module can send an event instruction to the session information acquisition module to indicate that the session information changes. After receiving the event instruction, the session information acquisition module may determine that the session information changes, and acquire the session information from the first storage medium.
Whether a session is established with another server by using the connection management interface or the application programming interface, the session needs to be established with another server by the network card driving module of the server. Based on this, the network card driver module may obtain all session information (e.g., session information when a session is established using the connection management interface, session information when a session is established using the application programming interface, etc.).
When the network card driving module stores the session information to the first storage medium, the session information may be stored to the first storage medium in a file format; therefore, the session information directly uses the file interface and is stored in the first storage medium in a directory and file mode, and the transparency of the session information is increased. Of course, the network card driver module may also store the session information in the first storage medium in other manners, which is not limited to this.
When the session information acquisition module acquires the session information from the first storage medium, the session information in the file format is acquired from the first storage medium, that is, the session information acquisition module can access the session information through a standard file interface, so that the application range of the session information acquisition module is expanded.
The session information acquisition module may monitor the network card driver module, determine that the session information changes (for example, session information of a newly-built session is added or an existing session is deleted) once an event instruction sent by the network card driver module is monitored, and acquire the session information from the first storage medium.
In the above embodiment, the first storage medium may include, but is not limited to, a memory of the server, and it is considered that the session information in the memory is deleted after power failure, therefore, after the session information acquisition module acquires the session information from the first storage medium, the session information may also be stored in the second storage medium, and the second storage medium may include, but is not limited to, a magnetic disk of the server, so as to ensure that the session information is not deleted due to power failure.
The disk of the server may further include, but is not limited to: a Solid State Drive (SSD), a Hybrid Hard Drive (HHD), a Hard Disk Drive (HDD), or the like, but may also be a phase change memory type Disk, a quantum memory type Disk, a graphene memory type Disk, or the like, and the type of the Disk is not limited.
In one example, protocols that support RDMA techniques may include, but are not limited to: IB (InfiniBand ), RoCE (RDMA over Converged Ethernet), iWARP (Internet Wide Area RDMA Protocol), etc., which are not limited to this, in this embodiment, RoCE is taken as an example for description, and the processing manner of other protocols is similar. In the RDMA technique based on the RoCE, the session information may also be referred to as RoCE session information.
In one example, a session refers to a mechanism that is established by both ends of a network through a transport layer and can be used for data exchange, and represents an end-to-end connection established through a RoCE technology, and all information corresponding to the session is called session information. The session information is an important parameter of RDMA, and the network connection state and the activity degree of network flow can be analyzed through the session information, so that the functions of helping to position network hotspots, assisting in troubleshooting and the like are achieved.
For example, if a connection is established between the server 1 and the server 2, the session information of the session corresponding to the connection may include, but is not limited to: session identifier, IP address of server 1, IP address of server 2, session state (such as establishment state, use state, destruction state, etc.), QP (Queue Pairs) information (such as QP number identifier, etc.) of server 1, QP information of server 2, etc. Of course, the above-mentioned session information is only an example of the present application, and the content of the session information is not limited in detail.
The RoCE is a standard of RDMA over ethernet, and may include two transmission modes, one mode is an RC (Reliable Connection) transmission mode, and the other mode is an UD (Unreliable data transmission) transmission mode. The RC transmission mode is a reliable transmission technology oriented to connection, and needs to ensure the reliability of transmission through mechanisms such as response and order preservation. The UD transmission mode is a non-connection-oriented data transmission technology, and mechanisms such as response and order preservation do not need to be provided to ensure the reliability of transmission. Based on this, the connection established between the server 1 and the server 2 may be an RC connection or an UD connection.
Wherein, QP (Queue Pairs) resources are basic resources for sending and receiving messages, and may include a sending Queue and a receiving Queue, each QP resource has a unique QP number identifier, and the QP resources are allocated and managed by network card hardware. For example, for a certain service 1 between the server 1 and the server 2, the server 1 allocates a QP resource a for the service 1, and the server 2 allocates a QP resource B for the service 1, so that when a connection is established between the server 1 and the server 2, the QP resource a of the server 1 is used to establish a connection with the QP resource B of the server 2, the QP information of the server 1 may be a QP number identifier of the QP resource a, and the QP information of the server 2 may be a QP number identifier of the QP resource B.
In an example, when establishing a connection between the QP resource a of the server 1 and the QP resource B of the server 2 to establish an RC connection or an UD connection, the server 1 may further send the QP number identifier of the QP resource a to the server 2, and the server 2 establishes a correspondence between the QP number identifier of the QP resource a and the QP number identifier of the QP resource B; similarly, the server 2 may also send the QP number identifier of the QP resource B to the server 1, and the server 1 establishes a correspondence between the QP number identifier of the QP resource B and the QP number identifier of the QP resource a. Of course, the above establishment procedure is only one example of establishing an RC connection or an UD connection, and the establishment procedure of the RC connection or the UD connection is not limited.
In the application scenario, referring to fig. 2A, a flowchart of a session information obtaining method provided in the embodiment of the present application is shown, where the method may be applied to a server, and the server may include but is not limited to: the method comprises the following steps of:
The network card driving module of the server can establish a session with another server no matter whether the connection management interface is used for establishing the session with another server or the application programming interface is used for establishing the session with another server. Based on this, the network card driver module may obtain all session information (e.g., session information when a session is established using the connection management interface, session information when a session is established using the application programming interface, etc.).
The network card driver module obtains the session information, which may include but is not limited to: when the server establishes a connection with another server through the network card driving module, the network card driving module can establish a session corresponding to the connection and acquire session information corresponding to the session, and the session information acquisition process is not limited.
In one example, the server establishes a connection with another server through the network card driver module, which may include but is not limited to: in the first mode, the network card driving module can acquire the connection information of another server from the application programming interface kernel module, and establish connection with the connection information of another server by using the connection information of the server. And in the second mode, the network card driving module can acquire the connection information of the other server from the connection management interface kernel module and establish connection with the connection information of the other server by using the connection information of the server.
For the first mode, if the server uses the application programming interface to establish the session, the application programming interface kernel module may obtain the connection information of another server (e.g., the IP address and QP information of another server) from another server, and provide the connection information of another server to the network card driver module. Based on this, the network card driver module may obtain the connection information of another server from the application programming interface kernel module, and obtain the connection information of the server (such as the IP address and QP information of the server), and the obtaining manner is not limited. Then, the network card driving module may establish a connection, such as an RC connection or an UD connection, with connection information of another server by using the connection information of the server, without limitation to the establishment process.
After the network card driving module establishes connection with the connection information of another server by using the connection information of the server, a session corresponding to the connection can be established, and session information corresponding to the session, such as a session identifier, an IP address of the server, an IP address of another server, a session state (such as an establishment state, a use state, a destruction state, and the like), QP information of the server, QP information of another server, and the like, can be acquired.
In order to obtain the connection information of the other server from the other server, the api kernel module may establish a TCP connection or a UDP (User Datagram Protocol) connection with the other server, and obtain the connection information of the other server from the other server through the TCP connection or the UDP connection, which is not limited to this process.
For the second mode, if the server uses the connection management interface to establish the session, the connection management interface kernel module may read the connection information of another server (e.g., the IP address and QP information of another server) from the user mode repository, and provide the connection information of another server to the network card driver module. Based on this, the network card driver module may obtain the connection information of another server from the connection management interface kernel module, and obtain the connection information of the server (such as the IP address and QP information of the server), and the obtaining manner is not limited. Then, the network card driving module may establish a connection, such as an RC connection or an UD connection, with connection information of another server by using the connection information of the server, without limitation to the establishment process.
After the network card driving module establishes connection with the connection information of another server by using the connection information of the server, a session corresponding to the connection can be established, and session information corresponding to the session, such as a session identifier, an IP address of the server, an IP address of another server, a session state (such as an establishment state, a use state, a destruction state, and the like), QP information of the server, QP information of another server, and the like, can be acquired.
The reading, by the connection management interface kernel module, connection information of another server from the user mode repository may include: receiving connection information of another server input by a user, and storing the connection information of the other server in a user mode storage library; or capturing the connection information of another server from all the data and storing the connection information of the other server into the user state storage library. The process is not limited as long as the connection information of another server can be obtained and stored in the user state repository. Based on this, the connection management interface kernel module may read connection information of another server from the user state repository.
In one example, the network card driver module stores the session information to the first storage medium, which may include but is not limited to: the network card driving module stores the session information to a first storage medium in a file format; that is, the session information can be directly saved in the first storage medium in a directory and file manner using the file interface, thereby increasing the transparency of the session information. Of course, the network card driving module may also store the session information in the first storage medium by using other manners, such as a picture format, and the storage format is not limited.
In an example, the network card driver module may further add a record locally, which indicates that a session is established between the server and another server, and the content of the record is not limited.
In one example, since the network card driving module can acquire all session information, when the session information changes each time, the network card driving module can acquire the change event and can send a first event instruction to the session information acquisition module to indicate that the session information has changed.
In step 203, the session information collection module obtains session information from the first storage medium according to the first event instruction. After receiving the first event instruction sent by the network card driving module, the session information acquisition module may determine that the session information changes, and acquire the session information from the first storage medium.
The session information acquisition module may monitor the network card driving module, determine that the session information changes (for example, session information for adding a new session) once a first event instruction sent by the network card driving module is monitored, and may acquire the session information for adding the new session from the first storage medium.
When the session information acquisition module acquires the session information from the first storage medium according to the first event instruction, the session information in the file format is acquired from the first storage medium according to the first event instruction, that is, the session information acquisition module can access the session information through a standard file interface, so that the application range of the session information acquisition module is expanded.
In the above embodiment, the first storage medium may include, but is not limited to, a memory of the server, and it is considered that the session information in the memory is deleted after power failure, therefore, after the session information acquisition module acquires the session information from the first storage medium according to the first event instruction, the session information may also be stored in the second storage medium, and the second storage medium may include, but is not limited to, a disk of the server, so as to ensure that the session information is not deleted due to power failure.
In an example, the execution sequence is only an example given for convenience of description, and in practical applications, the execution sequence between steps may also be changed, and the execution sequence is not limited. Moreover, in other embodiments, the steps of the respective methods do not have to be performed in the order shown and described herein, and the methods may include more or less steps than those described herein. Moreover, a single step described in this specification may be broken down into multiple steps for description in other embodiments; multiple steps described in this specification may be combined into a single step in other embodiments.
Referring to fig. 2B, another flowchart of a session information obtaining method is shown, where the method may be applied to a server, and the server may include a network card driving module and a session information collecting module, and the method may include:
in step 211, the network card driver module deletes the session corresponding to the session information recorded in the first storage medium.
The session deletion method includes that the network card drive module records a session corresponding to the session information in the first storage medium, and may include, but is not limited to: when the server is disconnected from another server through the network card driving module, the network card driving module may release the session corresponding to the connection, query session information corresponding to the session from the first storage medium, and record that the session corresponding to the session information is deleted in the first storage medium.
In one example, when the server is disconnected from another server, the network card driver module of the server may disconnect from the other server, and the network card driver module may release the session corresponding to the connection, and further, the network card driver module may query the session information corresponding to the session from the first storage medium, and record the session corresponding to the session information in the first storage medium and delete the session.
The network card driver module records that the session corresponding to the session information is deleted in the first storage medium, and may include but is not limited to: the network card driving module adds data in the session information of the first storage medium, where the data is used to indicate that the session corresponding to the session information is deleted, and the content of the data is not limited. Or, the network card driver module deletes the session information from the first storage medium, and after the session information is deleted, it may indicate that the session corresponding to the session information is deleted. Of course, the above-described manner is merely an example, and is not limited thereto.
In one example, after the network card driver module releases a session, a record may be added locally to indicate that the session between the server and another server is deleted, and the content of the record is not limited.
In step 212, the network card driver module sends a second event instruction to the session information collection module.
Because the network card driving module can know that the session is deleted, the network card driving module can send a second event instruction to the session information acquisition module to indicate that the session is deleted every time the session is deleted.
In step 213, the session information collection module obtains the session information of the deleted session from the first storage medium according to the second event instruction. After receiving the second event instruction sent by the network card driving module, the session information acquisition module may determine that the session is deleted, that is, the session corresponding to the session information is deleted, and therefore, the session information of the deleted session may be acquired from the first storage medium.
For example, if data is added to the session information of the first storage medium and the data indicates that the session corresponding to the session information is deleted, the session information collection module determines that the session information is the session information of the session that has been deleted by analyzing the data. Or, if the session information is deleted from the first storage medium, the session information that has been deleted is determined by comparing the current session information with the last session information.
The session information acquisition module can monitor the network card drive module, determine that a session is deleted once a second event instruction sent by the network card drive module is monitored, and can acquire session information of the deleted session from the first storage medium.
In an example, after the session information acquisition module acquires the session information of the session that has been deleted from the first storage medium according to the second event instruction, the session corresponding to the session information may also be recorded in the second storage medium to be deleted, and the recording manner is similar to the manner in which the session is recorded in the first storage medium to be deleted, and is not described herein again.
Based on the above technical scheme, in the embodiment of the application, after the network card driving module acquires the session information, the network card driving module may store the session information in the first storage medium, and send the first event instruction to the session information acquisition module. The session information acquisition module acquires the session information from the first storage medium after receiving the first event instruction, rather than acquiring the session information periodically, so that the problems that the acquisition period is not easy to determine, the session information is omitted and the like can be solved. For example, the session information collection module does not need to determine the collection period, and there is no problem in determining the collection period. In addition, when the session information changes every time, the network card driving module sends a first event instruction to the session information acquisition module to trigger the session information acquisition module to acquire the session information, namely, each change of the session information triggers the session information acquisition module to acquire the session information, so that all the session information can be acquired, the problem of session information loss is solved, the accuracy and the integrity of the session information are improved, the granularity and the timeliness of acquiring the session information are improved, and the influence on a service system is reduced.
Based on the same application concept as the above method, another session information acquisition method is also proposed in the embodiment of the present application, and referring to fig. 3, the method is a flowchart of the session information acquisition method proposed in the embodiment of the present application, and the method may be applied to a server, and the method may include the following steps:
The server establishes a connection with another server, and the method can include: acquiring the connection information of another server from an application programming interface kernel module of the server, and establishing connection with the connection information of the other server by using the connection information of the server; or acquiring the connection information of another server from the connection management interface kernel module of the server, and establishing connection with the connection information of the other server by using the connection information of the server.
For example, when a server establishes a connection with another server, the network card driving module establishes a session corresponding to the connection, acquires session information corresponding to the session, stores the session information in a first storage medium, and sends a first event instruction for the session information to the session information acquisition module. Further, after receiving the first event instruction for the session information, the session information collection module may determine that new session information is added to the first storage medium, and may obtain the new session information from the first storage medium.
The processing in steps 301 to 303 can be referred to as step 201 and 203, and will not be described herein.
In one example, when the server is disconnected from another server, the session corresponding to the connection may be released, the session information corresponding to the session is queried from the first storage medium, and the session corresponding to the session information is recorded in the first storage medium to be deleted; and receiving a second event instruction aiming at the session information, and acquiring the session information of the deleted session from the first storage medium according to the second event instruction. For example, when the server is disconnected from another server, the network card driving module releases the session corresponding to the connection, queries session information corresponding to the session from the first storage medium, records that the session corresponding to the session information is deleted in the first storage medium, and sends a second event instruction for the session information to the session information acquisition module. And after receiving a second event instruction aiming at the session information, the session information acquisition module acquires the session information of the deleted session from the first storage medium.
The processing of the above process can be referred to as step 211-213, which is not described herein again.
