Problems solved by technology

Since the link layer protocol (or layer 2 protocol) or other application protocols basically do not have this function, it is impossible to guarantee the maintenance of the session state of these protocols during the reset period, which will still cause link interruption and application session interruption to affect business
[0012] (2) For boards that integrate the control management layer and the forwarding layer, the switching of the active and standby boards will lead to the linkage switching of the forwarding layer, resulting in instantaneous service interruption
In addition, when the two boards are reset successively, the protocol session cannot be maintained

Embodiment 1

[0027] figure 1 It is a schematic diagram of the communication device in Embodiment 1 of the present invention. like figure 1 As shown: the communication device according to Embodiment 1 of the present invention includes: a control management device 10 and a forwarding processing device 20 . The control and management device 10 is configured to generate a protocol steady-state message corresponding to the stable state of the protocol, and send the protocol steady-state message and its corresponding forwarding information (such as an outgoing port number) to the forwarding processing device 20. The forwarding processing device 20 is configured to receive and store the protocol steady-state message and the forwarding information, and when the control and management device 10 is working normally, forward the control and management device 10 according to the forwarding information The issued protocol steady-state message is directly forwarded to the communication peer; when the ...

Embodiment 2

[0058] image 3 It is a schematic diagram of the communication device in Embodiment 2 of the present invention. like image 3 As shown, the communication device includes two boards, and each board includes a control management device and a forwarding processing device, and the two control management devices and the forwarding processing device are in the active state and the standby state respectively.

[0059] In an optional implementation, the two boards are the main board and the backup board respectively, the main board includes the main control management device 10 and the main forwarding processing device 20, and the backup board includes the standby control management device 50 and the standby forwarding device 20. In the processing device 60, the inside of the boards is connected through a Lanswitch, and information between different boards is exchanged through a bus. During the working process of the actual product, with the progress of the active / standby switchover...

Abstract

The embodiment of the invention provides a method for maintaining protocol state and communication equipment thereof, wherein the communication equipment comprises a control management device and a transmission processing device; the control management device is used for generating a protocol stable state message corresponding to the stable state of a protocol and issuing the protocol stable state message and corresponding transmission information thereof to the transmission processing device; the transmission processing device is used for receiving and storing the protocol stable state message and the corresponding transmission information issued by the control management device; and when the control management device is reset, a protocol stable state message which is stored and corresponds to the stable state of the protocol when the control management device is reset is periodically sent to a communication opposite end according to the transmission information. The communication equipment continues to periodically send the protocol stable state message through the transmission processing device to keep the current protocol session state away from interruption when the control management device is reset.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method for maintaining a protocol state and a communication device. Background technique [0002] With the development of network technology, there are more and more types of protocols. In the actual communication equipment implementation of most protocols, the protocol messages are usually controlled by the system's control management device (also known as the control management layer in this field, such as CPU) to generate and parse. Due to cost considerations, it may not be possible or suitable to configure a redundant backup unit for the CPU, that is, there is only one control and management board. In this scenario, it is necessary to rely on the CPU of a single board to run and maintain the communication protocol. If the board is reset, some protocol sessions in the communication system will be interrupted, which may lead to service interruption. [0003] H...
