Embodiment Construction
[0032] The invention points of the present invention will be specifically described below with reference to the drawings.
[0033] see figure 2 , which is a flow chart of the present invention using a single process to process the routing protocol stack. The method includes:
[0034] S110: When the process of the routing protocol stack is started, the routing protocol stack is initialized, and the initialization includes:
[0035] A: Establish a protocol registration linked list of each layer, each node of the protocol registration linked list saves the information of a protocol supported by this layer, and the information is used to process sending and receiving data and protocol events;
[0036] B: Establish a protocol event chain list, if the protocol receives an instruction from the application layer, add a node in the protocol event chain list to save the protocol event;
[0037] S120: Search each node of the protocol registration linked list in turn, and perform pack...

The invention discloses a method for processing a routing protocol stack using a single process, including: (1) when the process of the routing protocol stack is started, the routing protocol stack is initialized, and the initialization includes: A. Establishing a protocol registration list of each layer , each node of the protocol registration list saves the information of a protocol supported by this layer, and the information is used to process the sending and receiving data and protocol events; B. Establish the protocol event list, if the protocol receives the instruction sent by the application layer, the protocol event Add a node in the linked list to save the protocol event; (2) search each node of the protocol registration linked list in turn, and perform packet receiving and sending operations on the protocol corresponding to this node; (3) search each node of the protocol event linked list in turn, Call the handler function of the event corresponding to the node for processing. In addition, the present invention also adopts a unified timer management strategy. As a result, the operating efficiency and data throughput of the routing protocol stack are improved, thereby improving the operating efficiency of the CPU.
Description
technical field [0001] The invention relates to the communication field, in particular to a method for processing routing protocol stacks in network node devices with three-layer routing functions such as routers and multilayer switches. Background technique [0002] At present, network node devices with routing functions such as routers and multilayer switches are mainly used to connect multiple logically separated networks and perform data storage and forwarding functions between different networks. It can transmit data according to different link frames, and then complete the network layer relay task. The following takes a router as an example to describe its working process of routing and forwarding in detail. [0003] The routing is to determine the best path to the destination, which is realized by the routing algorithm in the routing protocol. In order to determine the best path, a routing table containing routing information is created according to the routing prot...
