Problems solved by technology

Therefore, for the protocol process that needs to maintain the protocol connection, the local device will establish the protocol connection with its directly connected peer device, and maintain the protocol connection by sending the protocol keep-alive message. In this case, once the protocol occurs The process is restarted. Before the restart is completed, the protocol process of the peer device will not be able to receive the keep-alive message of the protocol sent by the local device, which will cause the protocol process of the peer device to think that the connection has timed out and age it, affecting network stability. , the business is also interrupted due to the restart of the protocol process

Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and examples.

[0018] see first figure 1 , figure 1 It is a schematic structural diagram of a protocol process module in a prior art device, the protocol process module 110 includes a protocol control module 111 running on the control plane of the device, and a protocol data module 112 running on the data plane of the device; wherein,

[0019] The protocol control module 111 can also be said to be the control plane of the protocol, which is mainly used to control the operation of the protocol. For example, when the protocol process starts, the protocol control module 111 starts first to obtain various related configuration information of the protocol, and then according to the protocol The configuration information controls the protocol data modul...

Abstract

The invention provides a graceful restarting method and a graceful restarting device for a universal protocol process. The method comprises the following steps of: acquiring a keep-alive message of a protocol before the restarting of the protocol process; transmitting the keep-alive message of the protocol as an agent in a protocol process restarting process; and after the restarting of the protocol process is finished, retaking a keep-alive message transmission function over. By the method and the device, the interruption of a service can be avoided in the protocol process restarting process.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for smooth restarting of a general protocol process. Background technique [0002] The network is a place for information exchange, and all devices connected to the network can exchange information through physical connections with each other. However, the physical connection itself cannot exchange information. Each device in the network also needs to follow the same protocol rules, and realize the information exchange between each other by running the same protocol. [0003] Usually, multiple protocol processes are running in the device to implement different communication functions. Among them, some protocol processes need to maintain the protocol connection during the process of information exchange between devices. If the protocol connection is interrupted, the corresponding services will also be interrupted. Therefore, for the protocol process th...
