A message scheduling method and device

Abstract

The invention discloses a message scheduling method and equipment. The method comprises: after a forwarding chip of a network device receives a message, the forwarding chip uses the feature information carried in the message to perform feature matching; One type of feature, but not matched to the second type of feature, then add the message to the first priority queue; if the first type of feature is matched, and the second type of feature is matched, the message is added to the second priority queue; when the CPU of the network device is dispatching messages, the CPU judges whether there is a message in the second priority queue; if yes, then dispatches the messages in the second priority queue If not, judge whether there is a message in the first priority queue; if yes, schedule the message in the first priority queue. In the embodiment of the present invention, the network device can process the protocol message for maintaining the neighbor relationship in time.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a message scheduling method and equipment. Background technique [0002] With the rapid development of cloud computing technology, a large number of new technology standards have been applied in data center networks, and EVI (Ethernet Virtualization Interconnection, Ethernet virtualization interconnection technology) has also emerged. like figure 1 As shown in the figure, it is a schematic diagram of the networking of the EVI network. The EVI network is mainly based on the existing service provider network and enterprise network, and provides flexible Layer 2 interconnection functions for scattered physical sites. [0003] In an EVI network, the stability of the neighbor relationship will affect the topology stability and traffic forwarding of the entire Layer 2 network. Once the neighbor relationship fluctuates, it will cause constant MAC (Media Access Control, M...

AI Technical Summary

Problems solved by technology

[0005] When the protocol packets themselves are congested, the CPU cannot process the protocol packets used to maintain the neighbor relationship in time, resulting in neighbor flapping and the stability of the neighbor relationship cannot be effectively guaranteed.
