Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the prior art, as the scale of a distributed cloud is larger and larger, the number of distributed cloud sites is larger and larger, and different site traffic charges are different, so that cloud service users tend to the cheaper distributed cloud site traffic, and the traffic which can be digested in the same region needs to be digested across regions, thereby causing the problem of cross-region access, and reducing the utilization rate of a backbone network of a telecommunication operator.
Therefore, in view of the above problems, the technical idea of the present invention is to consider that the load of the backbone network is increased when performing cross-regional access, and therefore, when a client needs to access a distributed cloud site, the client is preferentially scheduled to the distributed cloud site in the region where the client is located to implement local-region access, and a flow control policy is set on the distributed cloud site in the region where the client is located, so that the distributed cloud site can only accept incoming flow of the same region, that is, only the client in the local region can access, thereby further ensuring local-region access of the client, that is, co-regional scheduling of flow, and effectively avoiding the problem of cross-regional access, thereby reducing the load of the backbone network and further reducing the construction cost of the backbone network.
The following describes the technical solutions of the present disclosure and how to solve the above technical problems in detail by specific examples. Several of these specific examples may be combined with each other below, and some of the same or similar concepts or processes may not be repeated in some examples. Examples of the present disclosure will now be described with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a traffic scheduling system according to an embodiment of the present invention, and as shown in fig. 1, the traffic scheduling system includes a client 101, a scheduling system 102, and a server 103 in different regions, that is, a region 1 and a region 2. The client 101 sends a domain name resolution request to the scheduling system 102, the scheduling system 102 determines that a server to be accessed by the client is a server 1 in a region 1, generates a domain name resolution result based on an address of the server 1, and sends the domain name resolution result to the client 101, and the client 101 extracts the address of the server 1 from the domain name resolution result and sends the access request to the server 1 based on the address of the server 1.
The client may be a mobile terminal (e.g., a mobile phone, a tablet computer, etc.), a computer, or other terminal device.
The server is a server, a computer and other devices, and specifically, the server can be a distributed cloud site. The number of the servers in different regions, i.e. region 1 and region 2, can be set according to the actual situation, and the application does not limit the number.
Fig. 2 is a first schematic flow chart of a traffic scheduling method according to an embodiment of the present invention, where an execution main body of the embodiment may be a client. As shown in fig. 2, the method includes:
s201, sending a domain name resolution request to a scheduling system, so that the scheduling system determines the address of a target server corresponding to a domain name to be accessed in the domain name resolution request according to a preset scheduling rule, generates a domain name resolution result comprising the address of the target server, and controls the target server to execute a flow area restriction rule setting operation. The target server and the client belong to the same region.
In this embodiment, in the process of using the relevant application program by the user, the client where the application program is located needs to access the server, that is, a certain distributed cloud site, to perform some operations (for example, to obtain the relevant resources). When a client accesses a server, a domain name of the server to be accessed, namely a domain name to be accessed, is acquired, and a domain name resolution request including the domain name to be accessed is generated based on a preset domain name resolution format. And after the domain name resolution request is generated, sending the resolution request to a scheduling system.
After receiving the domain name resolution request, the scheduling system acquires a domain name to be accessed in the domain name resolution request, namely the domain name of the server, searches for the server with the domain name of the domain name to be accessed, searches for the server with the region of the client from the server with the domain name of the domain name to be accessed, and determines the server as a target server, wherein the region of the target server is the same as the region of the client. The method comprises the steps of obtaining an address of a target server, generating a domain name resolution result comprising the address of the target server based on a preset resolution result format, and sending the domain name resolution result to a client so that the client can access a corresponding server by using the domain name resolution result, namely, the target server.
In order to more accurately avoid cross-region access, the scheduling system sets a traffic region limitation rule at the target server, namely controls the target server to execute traffic region limitation rule setting operation, so that the target server only receives access of clients in the same region.
Optionally, when the scheduling system controls the target server to execute the traffic region restriction rule setting operation, the scheduling system may generate a traffic region restriction rule setting request including a region to which the client belongs, that is, a region to which the target server belongs, and send the traffic region restriction rule setting request to the target server, and after receiving the setting request, the target server performs the traffic region restriction rule setting operation, that is, sets the traffic region restriction rule, so as to receive only an access request sent by the client in the region to which the target server belongs, that is, only the client in the region to which the target server belongs may access the target server.
Optionally, the traffic region restriction rule indicates that the service end is restricted from receiving an access request sent by a client in the local region, that is, when the client and the service end belong to the same region, the client can access the service end, that is, the service end only receives the incoming traffic of the region where the source address is the service end.
In addition, optionally, the domain name resolution request further includes a source address and an address of the client. When the area to which the client belongs is determined, the area to which the client belongs is determined through the address of the client, namely the area corresponding to the address of the client is searched and determined as the area to which the client belongs.
In addition, each server, namely, the region to which the distributed cloud site belongs, is pre-stored to a designated position, so that when a target server corresponding to the client is searched, the region to which each server belongs can be obtained from the designated position. And when the region to which the server belongs is the same as the region to which the client belongs, taking the server as a target server.
The address is a network address, such as an Internet Protocol (IP) address.
S202, obtaining a domain name resolution result sent by the scheduling system, and accessing a target server according to the domain name resolution result.
In this embodiment, the client receives the domain name resolution result sent by the scheduling system, and extracts the address of the target server from the domain name resolution result, so as to access the target server by using the address of the target server, that is, generate a corresponding access request to the target server, and implement local access, that is, implement local traffic digestion.
In this embodiment, the scheduling system may correspond to a terminal, and the terminal performs all operations required to be performed by the scheduling system. Optionally, in order to improve the operation efficiency of the scheduling system, the scheduling system may have a plurality of terminals, that is, the scheduling system includes a first terminal and a second terminal, and the first terminal and the second terminal cooperate with each other, so as to improve the overall operation efficiency of the scheduling system.
Specifically, taking live broadcast software as an example, a server, that is, a distributed cloud site is a server corresponding to the live broadcast software and is deployed in a plurality of regions, a scheduling system is a CDN (Content Delivery Network) system and is deployed in a certain region, and a client is a live broadcast software client on a mobile terminal used by a user, that is, a client where the live broadcast software is located, and is distributed in each region. The live broadcast software client accesses the server corresponding to the live broadcast software, the CDN system scheduling is needed to schedule an access target to one of the live broadcast software servers, for example, the server located in the region 1, and finally the live broadcast software client on the mobile terminal directly accesses the server deployed in the region 1.
Further, when the scheduling system includes the first terminal and the second terminal, the traffic scheduling process may be performed in the following two ways.
One way is that a domain name resolution request is sent to a second terminal through a first terminal, so that the second terminal determines an address of a target server corresponding to a domain name to be accessed in the domain name resolution request according to a preset scheduling rule, controls the target server to execute a traffic area restriction rule setting operation, and sends the address of the target server to the first terminal. And acquiring a domain name resolution result sent by the first terminal, wherein the domain name resolution result is generated by the first terminal according to the address of the target server sent by the second terminal.
Specifically, as shown in fig. 3, the client communicates with the second terminal through the first terminal, and the specific process includes: firstly, a client sends a domain name resolution request to a first terminal. And the first terminal sends the domain name resolution request to the second terminal. And thirdly, the second terminal determines a server belonging to the same region as the client based on the domain name resolution request so as to obtain a target server, and sets a flow control strategy at the target server, namely controls the target server to execute flow region restriction rule setting operation. And fourthly, sending the address of the target server to the first terminal. And the first terminal generates a domain name resolution result comprising the address of the target server and sends the domain name resolution result to the client. The client accesses the target server, namely the server in the region 1, according to the address of the target server.
Another way is to obtain the address of the second terminal sent by the first terminal. And sending the domain name resolution request to a second terminal so that the second terminal determines the address of a target server corresponding to the domain name to be accessed in the domain name resolution request according to a preset scheduling rule, controls the target server to execute flow area restriction rule setting operation and generates a domain name resolution result comprising the address of the target server. And acquiring a domain name resolution result sent by the second terminal.
Specifically, as shown in fig. 4, the client requests domain name resolution from the first terminal. And the first terminal sends the address of the second terminal to the client. And the client side sends the domain name including the service side needing to be accessed to the second terminal. And fourthly, the second terminal determines a server belonging to the same region as the client based on the domain name resolution request to obtain a target server, and sets a flow control strategy at the target server, namely controls the target server to execute flow region restriction rule setting operation. And the second terminal generates a domain name resolution result comprising the address of the target server and sends the domain name resolution result to the client. The client accesses the target server, namely the server in the region 1, according to the address of the target server.
Optionally, when the control target server executes the traffic region restriction rule setting operation, a dynamic traffic control policy may be implemented by using the security group API of the target server, and even if the target server only receives an incoming traffic whose source IP address is in the same region, all outgoing traffic is released, so that the traffic is digested in the distributed cloud sites in the same region as much as possible.
In addition, optionally, flow control on the distributed cloud site may also be implemented by using a firewall function on the cloud.
Optionally, the second terminal provides the scheduling service by means of 302 hopping.
In this embodiment, a local server accessible to a client is determined for an address of the client, that is, a local server into which traffic corresponding to the client needs to enter is determined, so that incoming traffic is preferentially scheduled to a local server in the same region, and cross-region access is avoided, so that the utilization rate of a backbone network is higher, and the use cost of a cloud service user is reduced.
In this embodiment, a distributed bandwidth function is provided in the distributed cloud, which bundles bandwidths of multiple distributed cloud sites into a virtual bandwidth to be provided to the outside and automatically completes scheduling logic of traffic local domain digestion. The traffic is digested in a local domain as much as possible through a security group function and a scheduling system of a distributed cloud site, namely a server side, and the utilization rate of a backbone network is improved.
In this embodiment, when a distributed cloud site, that is, a server needs to be accessed, a corresponding domain name resolution request is sent to a scheduling system, so that the scheduling system determines an address of a target server that a client needs to access based on the domain name resolution request, the target server and the client belong to the same region, so that the client accesses the target server according to the address of the target server, thereby achieving the access in the same region on the basis of achieving normal access, and the scheduling system controls the target server to execute a traffic region restriction rule setting operation, so that the target server can only receive the access of the client in the same region, that is, only the traffic in the same region can be reduced, thereby further ensuring the access in the same region, avoiding the problem of cross-region access, and thus effectively reducing the load of a backbone network and reducing the construction cost of the backbone network.
Fig. 5 is a second flowchart of the traffic scheduling method according to the embodiment of the present invention, where an execution subject of this embodiment may be a scheduling system, specifically, a terminal corresponding to the scheduling system. As shown in fig. 5, the method includes:
s501, receiving a domain name resolution request sent by a client.
S502, determining the address of a target server corresponding to the domain name to be accessed in the domain name resolution request according to a preset scheduling rule, generating a domain name resolution result comprising the address of the target server, and controlling the target server to execute a flow area restriction rule setting operation. The target server and the client belong to the same region.
And S503, sending the domain name resolution result to the client so that the client accesses the target server according to the domain name resolution result.
In this embodiment, when the scheduling system receives a domain name resolution request sent by a client, it indicates that the client needs to access a distributed cloud site corresponding to a domain name to be accessed in the domain name resolution request, that is, a server, and then determines a distributed cloud site in a region to which the client belongs from the distributed cloud site to obtain a target site, that is, a target server. The method comprises the steps of obtaining an address of a target server, generating a domain name resolution result containing the address of the target server, and sending the domain name resolution result to a client, so that the client can access the target server according to the address of the target server in the domain name resolution result, and the same-region access is realized.
In this embodiment, when the scheduling system determines the target server, a flow control policy, that is, a flow area restriction rule, may be set at the target server, so that only the client in the area to which the target server belongs may access the target server, thereby effectively avoiding cross-area access.
Fig. 6 is a third schematic flowchart of a component processing method according to an embodiment of the present invention, and in this embodiment, on the basis of the embodiment of fig. 5, when a target server is determined, the determination may be performed according to a region to which a client belongs and a delay requirement, and this process will be described below with reference to a specific embodiment. As shown in fig. 6, the method includes:
s601, receiving a domain name resolution request sent by a client.
S602, obtaining the region of the client and obtaining the delay limit time corresponding to the client.
In this embodiment, after receiving a domain name resolution request sent by a client, a region where the client is located is searched according to an address of the client, that is, a region to which the client belongs is obtained, and a delay requirement, that is, a delay limit time, corresponding to the client is obtained.
The delay limit time corresponding to the client represents the requirement of the client for the delay, namely the maximum delay time acceptable to the client. The delay limit time corresponding to the client may be obtained from the domain name resolution request, that is, the domain name resolution request includes the delay limit time corresponding to the client. Or, the determination may be performed according to the domain name to be accessed in the domain name resolution request, that is, the delay time corresponding to the domain name to be accessed is searched, and the determination is determined as the delay limit time corresponding to the client.

In this embodiment, after the region of the server corresponding to the domain name to be accessed is obtained, after each server corresponding to the domain name to be accessed is determined, for each server, whether the region to which the server belongs is the same as the region to which the client belongs is determined, and if so, the server is determined to be the first server.
S605, obtaining the load value of each first service end and the delay time range corresponding to the load value of the first service end.
In this embodiment, since there may be multiple sites, that is, multiple first service ends, in the same geographical situation, when the number of the first service ends is multiple, and a target service end needs to be determined from the first service ends, the current load value of each first service end is obtained, so as to obtain the load value of the first service end. For each first service end, searching a load range where a load value of the first service end is located from a preset load delay mapping table, and taking a delay time range corresponding to the load range as a delay time range corresponding to the load value of the first service end, namely the delay time range corresponding to the first service end.
The preset load delay mapping table comprises at least one load range and a delay time range corresponding to each load range.
The current load value of the server may be represented by the total number of clients currently accessing the server, or may be represented by other types of data (for example, CPU utilization, memory utilization, and the like), which is not limited herein.
In addition, when the number of the first service end is one, the first service end may be used as a target service end.
In addition, when the target server is determined from the first servers, other rules such as packet loss rate, delay jitter, retransmission rate, and the like may also be used for determining, for example, the determination is performed based on the packet loss rate corresponding to each first server.
S606, if the delay limiting time belongs to the delay time range corresponding to the load value of the first service end, the address of the first service end is obtained and determined as the address of the target service end.
In this embodiment, for each first service, when the delay time limit corresponding to the client is within the delay time range corresponding to the first service, that is, the delay time range corresponding to the load value of the first service, it is determined that the first service is the second service.
And when the number of the second service terminals is one, directly taking the second service terminals as target service terminals.
And when the number of the second service ends is one, determining a target service end from the second service ends, namely selecting one second service end from the second service ends, and taking the selected second service end as the target service end.
Further, when the target server is determined from the second servers, one second server may be arbitrarily selected and determined as the target server, or the second server with the smallest load value may be used as the target server.
S607, generating a domain name resolution result including the address of the target server, and controlling the target server to execute the traffic region restriction rule setting operation.
And S608, sending the domain name resolution result to the client so that the client accesses the target server according to the domain name resolution result.
In this embodiment, when a target server accessed by a client is determined, a server in a region to which the client belongs is screened out, and a first server is determined, and when a delay time limit corresponding to the client is within a delay time range corresponding to the first server, it is indicated that the first server can meet a response requirement of the client, so that the first server can be used as the target server, and the response requirement of the client is met on the basis of avoiding cross-region access.
In this embodiment, when the target server is determined, the determination is performed according to the delay requirement and the load value of the server, that is, when a plurality of distributed cloud sites exist in the same region, the server with the minimum load pressure is determined based on the requirement of the client and the load request of the distributed cloud sites, and the target server accessible to the client is determined, so that the delay is reduced, and the throughput of the distributed cloud sites is improved.
