Embodiment

[0076] Such as figure 1 Shown, the method for a kind of RSTP state machine scheduling of the present invention comprises the following steps:

[0077] S1: divide the sub-state machine into three sets according to the sending and receiving function of the sub-state machine in the RSTP state machine and the state that affects the reception of the message: set A, set B and set C;

[0078] Among them, set A is a sub-state machine that will directly affect the received message; set B is a sub-state machine that does not directly affect the received message; set C is a sub-state machine that sends a message;

[0079] S2: Run the sub-state machines in set A;

[0080] S3: After the sub-state machines in set A are finished running, run the sub-state machines in set B;

[0081] S4: After the sub-state machines in the set B are completed, run the sub-state machines in the set C.

[0082] During the implementation of this embodiment, the running order of the sub-state machines is deter...

Abstract

The invention discloses an RSTP state machine scheduling method. The method comprises the following steps: S1, dividing sub-state machines into a set A, a set B and a set C, wherein the set A is a sub-state machine which can directly generate influence when receiving the message, the set B is a sub-state machine which does not directly influence the received message, and the set C is a sub-state machine for sending a message; S2, operating the sub-state machines in the set A; S3, after the sub-state machines in the set A are operated, operating the sub-state machines in the set B; S4, after the sub-state machines in the set B are operated, operating the sub-state machines in the set C. According to the RSTP state machine scheduling method and system provided by the invention, the state machines of RSTP state machines are divided into three sets, and the operation sequence of the sets is set, so the operation disorder of the RSTP state machines in the operation process can be reduced, the state abnormality is avoided, and the convergence time is shortened.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and system for scheduling an RSTP state machine. Background technique [0002] The RSTP protocol (Rapid Spanning Tree Protocol) is the rapid spanning tree protocol. The rapid spanning tree protocol can quickly remove the loop in the network and avoid the storm in the network. It is widely used in various network scenarios, and the realization of RSTP The core of the protocol is the rapid spanning tree state machine (Rapid Spanning Treestate machines) in the protocol, but the complexity of the rapid spanning tree state machine is relatively high. It is composed of nine sub-state machines. Its main functions and abbreviated names in the following are as follows : [0003] Port Receive state machine [0004] The port receiving state machine, hereinafter abbreviated as prsm, is used for preliminary parsing of the received BPDU message. [0005] Port Protocol Migrati...
