Virtual local area networks (Virtual Local Area Network, VLANs) are a technique for logically dividing Local Area Network (LAN) devices into individual segments, thereby implementing data switching for virtual workgroups (units).
An ONU management control interface (ONU MANAGEMENT AND Control Interface, OMCI) is a protocol defined in the GPON standard for information interaction between the OLT and the ONTs, and is used for managing the ONTs by the OLT in the GPON network, including configuration management, fault management, performance management, security management, and the like.
The data communication method provided by the embodiment of the application can be applied to an application environment shown in fig. 1. The application environment may include gateway devices, FTTR modules, and sub-devices. The gateway device can be a gateway in optical networking of enterprises and other enterprises or specific institutions, the gateway device can comprise a calculation module, the sub-devices can be an underhung slave device and an existing network gateway in the optical networking, for example, a slave device 1 (for example, a camera) and a slave device 2 (for example, a computer (Personal Computer, a PC)) and the like, the underhung slave device and the existing network gateway comprise various terminal devices (for example, a computer, a printer, a camera and the like) and the existing network gateway device, and the communication connection with the gateway device is realized through accessing FTTR modules through a PON port, so that a complete network system is constructed. The terminal can be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, internet of things devices and portable wearable devices, and the internet of things devices can be smart speakers, smart televisions, smart air conditioners, smart vehicle devices, projection devices and the like. The portable wearable device may be a smart watch, smart bracelet, headset, or the like. The head-mounted device may be a Virtual Reality (VR) device, an augmented Reality (Augmented Reality, AR) device, smart glasses, or the like.
In the all-optical networking, the gateway device can realize networking through an expansion FTTR module, the FTTR module is composed of an Ethernet interface and a Passive Optical Network (PON) lower interface, the upper interface is connected with the gateway device, the lower interface is used for accessing the lower hanging slave device, the existing network gateway and the like, and data transmission among devices at different levels is realized.
First, an OMCC (OMCI channel) may be established between an Optical line terminal (Optical LINE TERMINAL, OLT) and an Optical network terminal (Optical network terminal, ONT). The OMCI channel is a basic channel for information interaction between the two parties, and enables the two parties to perform stable communication connection through a specific protocol and configuration parameters. The OLT may be analogous to the role of gateway devices in PON networks, and the ONTs may be analogous to underhung slaves or existing gateways. Next, the down slave device or the existing network gateway enters an O5 state after completing the startup and initialization process. In this state, the device already has basic operating conditions and is ready for information interaction with the OLT. Further, the down slave device or the existing network gateway may encapsulate its own media access Control Address (MAC) information, i.e. device Address information, into a specific OMCI message according to a format and coding manner specified by the OMCI protocol, where the OMCI message may include current service flow message data. After receiving the OMCI message containing the MAC address information, the gateway device decodes the message according to the parsing rule of the OMCI protocol, and extracts the content such as the MAC address information and the device identifier related to the MAC address information. And the MAC address information obtained by analysis is associated with the corresponding down-hanging equipment or the current network gateway, and is stored in a local management database or a memory table. In this way, the gateway device can rapidly identify and manage different down-hanging devices according to the MAC address in the subsequent business flow processing and automatic negotiation process, and realize the effective management and control of the whole network device and the optimization processing of data communication.
In addition, the gateway device continuously monitors any one of the service flow message data forwarded by the gateway device, for example, a message size of a camera down-hanging from the slave device 1 (MAC address 0, MAC address 6) is 60 bytes, a message size of a PC down-hanging from the slave device 2 (MAC address 1, MAC address G) is 88 bytes, and a message size of an industrial terminal down-hanging from the current network gateway (MAC address 4, MAC address 9) is 56 bytes. The data packet of the service flow message data comprises a certain data packet head information and a payload (data part), and the total length of the data packet is the message size, namely the message length. The gateway device obtains the size information of the traffic stream packet data by analyzing the relevant fields of the packet header (e.g., length fields in ethernet frames, etc.). Therefore, the gateway equipment can acquire the service flow message length of any one piece of current service flow message data. The gateway device may then determine a communication configuration policy for the current traffic stream message data according to the traffic stream message length, and perform traffic communication for the current traffic stream message data according to the communication configuration policy.
In a possible implementation manner, the number of connections of the lower hanging device can be increased, and the connection FTTR module can be extended in other upper connection ports eth ports, such as eth2, and adjusted according to the same communication configuration strategy, so that the expandability and flexibility of the all-optical networking are greatly enhanced.
In an exemplary embodiment, as shown in fig. 2, a data communication method is provided, where this embodiment is applied to a gateway device for illustration, it is understood that the method may also be applied to a terminal, and may also be applied to a system including a terminal and a server, and implemented through interaction between the terminal and the server. In this embodiment, the method includes the steps of:
step 102, monitoring the current service flow message data of the current sub-equipment.
In one possible implementation manner, the gateway device may be a gateway device in an optical networking, and the sub device may be an underhung slave device and an existing network gateway in the optical networking. The down-hanging slave device and the existing network gateway comprise various terminal devices (such as computers, printers, cameras and the like) and the existing network gateway device, and are connected with the FTTR module through a PON port, so that communication connection with the gateway device is realized, and a complete network system is constructed. In this step, the gateway device continuously monitors any one current traffic stream message data among the traffic stream message data forwarded by the gateway device.
Step 104, obtaining the service flow message length of the current service flow message data.
The data packet of any one current service flow message data comprises certain data packet head information and a payload (data part), and the total length of the data packet is the message size, namely the message length. The gateway device obtains the size information of the traffic stream packet data by analyzing the relevant fields of the packet header (e.g., length fields in ethernet frames, etc.). Therefore, the gateway device can acquire the service flow message length of any one current service flow message data, and the service flow message length can be used for representing the message size of the corresponding service flow message data. For example, the size of the message with the camera down-hanging from the slave device 1 (MAC address 0) and the size of the message with the PC down-hanging from the slave device 2 (MAC address 1) and the size of the message with the camera down-hanging from the slave device 2 (MAC address 1) and the size of the message with the industrial terminal down-hanging from the current network gateway (MAC address 4) and the size of the message with the slave device 2 (MAC address 1) and the size of the message with the slave device 2 (MAC address 9) are respectively 60 bytes and 56 bytes.
And step 106, determining the communication configuration strategy of the current service flow message data according to the service flow message length.
In this step, the gateway device may determine, according to the service flow message length of any one of the current service flow message data, a communication configuration policy of the current service flow message data, where different service flow message lengths correspond to different communication configuration policies, and the communication configuration policy is used to represent a communication configuration required for transmitting the current service flow message data. The communication configuration policy may include a first communication configuration policy and a second communication configuration policy, and if the communication configuration policy of the current service flow packet data is the first communication configuration policy, it indicates that corresponding data processing needs to be performed on the current service flow packet data before the gateway device forwards the current service flow packet data. If the communication configuration policy of the current service flow message data is the second communication configuration policy, the gateway device may directly forward the current service flow message data without performing data processing on the current service flow message data. Specifically, if the length of the service flow message is smaller than a first preset message length threshold (for example, 64 bytes), determining that the communication configuration policy of the current service flow message data is a first communication configuration policy, and for the first communication configuration policy, the gateway device may obtain device identification information, for example, MAC address information, corresponding to the current service flow message data according to the current service flow message data, and further may determine, according to the MAC address information, a current sub-device corresponding to the current service flow message data, where the current sub-device may be a down-hanging slave device and a current network gateway in an optical networking. Further, in one possible implementation, if the traffic flow packet length is smaller than the first preset packet length threshold (e.g. 64 bytes) and is greater than or equal to the second preset packet length threshold (e.g. 60 bytes), the gateway device may allocate a VLAN (virtual local area network) to the current traffic flow packet data of the current sub-device, specifically may associate a specific virtual local area network identifier VLAN ID with the down-hanging device or port to which the traffic flow belongs in the configuration of the gateway device, e.g. may select an unused VLAN ID from a predefined VLAN pool (e.g. VLAN 101, VLAN 102, etc.) and configure it into the port or associated forwarding rule to which the current child device is connected. By distributing VLAN, the service flows of different types or demands can be logically divided into different virtual local area networks, thereby realizing isolation and management of network traffic and improving the security and performance of the network. In another possible implementation manner, if the service flow message length is smaller than a second preset message length threshold (for example, 60 bytes), the gateway device sends a data filling instruction for the current service flow message data to the current sub-device, and sends an instruction to the target hooking device through OMCI message or other specific communication protocol, the current sub-device is used for executing the data filling instruction, performing data filling on the current service flow message data, and adding specific filling data (for example, 0000) to the payload part of the original current service flow message data until the service flow message length is greater than or equal to the second preset message length threshold, namely, 60 bytes, and the second preset message length threshold is smaller than the first preset message length threshold. Further, the gateway device may allocate a VLAN (virtual local area network) for the current traffic flow packet data of the current sub-device. If the length of the service flow message is greater than or equal to the first preset message length threshold (for example, 64 bytes), determining that the communication configuration policy of the current service flow message data is a second communication configuration policy, and for the second communication configuration policy, the gateway device can directly forward the current service flow message data, and network devices such as a switch and the like can accurately forward the message to the target device or the next hop network node according to the destination MAC address information of the current service flow message data. For example, the service flow packet size of the camera is 60 bytes, the gateway device is triggered to allocate VLAN101 to the slave device (MAC address 0x 6), the service flow packet size of the PC is 88 bytes, no processing is performed, and the service flow packet size of the industrial terminal is 56 bytes, the master device is triggered to allocate VLAN103 to the slave device (MAC address 4 x 9), and the device is notified to supplement user data to 60 bytes.
And step 108, carrying out service communication on the current service flow message data according to the communication configuration strategy.
The gateway device may obtain device identification information corresponding to the current service flow message data according to the current service flow message data, for example, MAC address information, where the MAC address information may include source MAC address information and destination MAC address information, and the gateway device may forward the current service flow message data according to a network topology structure, a routing rule, and a communication configuration policy, where network devices such as a switch accurately forward a message to a target device or a next hop network node according to destination MAC address information and/or a VLAN tag of the current service flow message data.
In the method of the embodiment, the gateway equipment can monitor the current service flow message data of the current sub-equipment, acquire the service flow message length of the current service flow message data, determine the communication configuration strategy of the current service flow message data according to the service flow message length, and perform service communication on the current service flow message data according to the communication configuration strategy. In the method provided by the embodiment of the application, the gateway equipment can determine the communication configuration strategy of the current service flow message data according to the monitored service flow message length of the current service flow message data so as to ensure that the message data with different message sizes can be normally communicated, avoid the problem that the message data with the message length lower than 64 bytes is easy to lose packets in the transmission process, and improve the flexibility, compatibility, comprehensiveness and safety of data communication.
In an exemplary embodiment, step 106 may include:
if the length of the service flow message is smaller than the first preset message length threshold, determining that the communication configuration strategy of the current service flow message data is the first communication configuration strategy.
Further, as shown in fig. 3, step 108 may include steps 302 through 306. Wherein:
step 302, determining a current sub-device corresponding to the current service flow message data according to the first communication configuration strategy.
Step 304, determining an associated virtual local area network identifier of the current sub-device according to the first communication configuration policy.
And 306, carrying out service communication on the current service flow message data according to the associated virtual local area network identifier.
And for the first communication configuration strategy, the gateway device can acquire device identification information, such as MAC address information, corresponding to the current service flow message data according to the current service flow message data, and further can determine the current sub-device corresponding to the current service flow message data according to the MAC address information, wherein the current sub-device can be a down-hanging slave device and a current network gateway in an optical networking. Further, in one possible implementation, if the traffic flow packet length is smaller than the first preset packet length threshold (e.g., 64 bytes) and is greater than or equal to the second preset packet length threshold (e.g., 60 bytes), the gateway device may allocate a VLAN (virtual local area network) to the current traffic flow packet data of the current sub-device, specifically may associate a specific virtual local area network identifier VLAN ID with the hanging device or the port to which the traffic flow belongs in the configuration of the gateway device, for example, may select an unused VLAN ID (e.g., VLAN 101, VLAN 102, etc.) from a predefined VLAN pool and configure the VLAN ID into the port or the associated forwarding rule connected to the current sub-device. By distributing VLAN, the service flows of different types or demands can be logically divided into different virtual local area networks, thereby realizing isolation and management of network traffic and improving the security and performance of the network. In another possible implementation manner, if the service flow message length is smaller than a second preset message length threshold (for example, 60 bytes), the gateway device sends a data filling instruction for the current service flow message data to the current sub-device, and sends an instruction to the target hooking device through OMCI message or other specific communication protocol, the current sub-device is used for executing the data filling instruction, performing data filling on the current service flow message data, and adding specific filling data (for example, 0000) to the payload part of the original current service flow message data until the service flow message length is greater than or equal to the second preset message length threshold, namely, 60 bytes, and the second preset message length threshold is smaller than the first preset message length threshold. Further, the gateway device may allocate a VLAN (virtual local area network) for the current traffic flow packet data of the current sub-device.
In the method of the embodiment, the gateway device can determine the communication configuration strategy of the current service flow message data according to the monitored service flow message length of the current service flow message data so as to ensure that message data with different message sizes can be normally communicated, avoid the problem that the message data with the message length lower than 64 bytes is easy to lose packets in the transmission process, and improve the flexibility, compatibility, comprehensiveness and safety of data communication.
In an exemplary embodiment, as shown in FIG. 4, step 302 may include steps 402 through 404. Wherein:
Step 402, according to the first communication configuration policy, obtaining the equipment identification information contained in the current service flow message data.
Step 404, determining the current sub-device corresponding to the current service flow message data according to the device identification information.
The gateway device may obtain, according to the current service flow packet data, device identification information, for example, MAC address information, corresponding to the current service flow packet data, and further may determine, according to the MAC address information, a current sub-device corresponding to the current service flow packet data, where the current sub-device may be a down-hanging slave device and a current network gateway in an optical networking.
In the method of the embodiment, the gateway device can analyze the MAC address information of the current service flow message data, and further, can identify the current sub-device corresponding to the current service flow message data, and can improve the efficiency and the accuracy of data transmission.
In an exemplary embodiment, before step 304, the method may further include:
If the service flow message length is smaller than a second preset message length threshold, transmitting a data filling instruction aiming at the current service flow message data to current sub-equipment, wherein the current sub-equipment is used for executing the data filling instruction and performing data filling on the current service flow message data until the service flow message length is larger than or equal to the second preset message length threshold, and the second preset message length threshold is smaller than the first preset message length threshold.
In an exemplary embodiment, step 106 may include:
If the length of the service flow message is greater than or equal to the first preset message length threshold, determining that the communication configuration strategy of the current service flow message data is a second communication configuration strategy.
Further, step 108 may include performing traffic communication on the current traffic flow message data according to a second communication configuration policy.
If the length of the service flow message is greater than or equal to the first preset message length threshold (for example, 64 bytes), determining that the communication configuration policy of the current service flow message data is a second communication configuration policy, and for the second communication configuration policy, the gateway device can directly forward the current service flow message data, and network devices such as a switch and the like can accurately forward the message to the target device or the next hop network node according to the destination MAC address information of the current service flow message data.
In the method of the embodiment, when the gateway device determines that the length of the service flow message is greater than or equal to the first preset message length threshold, the gateway device can directly forward the current service flow message data without performing corresponding data processing, thereby improving the efficiency and simplicity of data transmission.
In an exemplary embodiment, as shown in fig. 5, the step of performing service communication on the current service flow packet data according to the second communication configuration policy may include steps 502 to 504. Wherein:
step 502, determining the sending address information and the receiving address information corresponding to the current service flow message data according to the current service flow message data.
And step 504, carrying out service communication on the current service flow message data according to the sending address information and the receiving address information.
The gateway device may obtain, according to the current service flow packet data, device identification information corresponding to the current service flow packet data, for example, MAC address information, where the MAC address information may include source MAC address information and destination MAC address information, the sending address information may be source MAC address information, and the receiving address information may be destination MAC address information. The gateway device can forward the current service flow message data according to the network topology structure, the routing rule and the communication configuration strategy, and the network devices such as the switch can accurately forward the message to the target device or the next hop network node according to the destination MAC address information of the current service flow message data.
In the method of the embodiment, the gateway device can determine the communication configuration strategy of the current service flow message data according to the monitored service flow message length of the current service flow message data so as to ensure that message data with different message sizes can be normally communicated, avoid the problem that the message data with the message length lower than 64 bytes is easy to lose packets in the transmission process, and improve the flexibility, compatibility, comprehensiveness and safety of data communication.
