Problems solved by technology

However, when there is a large difference in the interface traffic in each group, the load sharing traffic to the two switching cards will be uneven. When the business volume carried by the switching cards reaches the upper limit, a large number of packets will be lost, thereby reducing Cross-card forwarding capability of the entire distributed network equipment

Abstract

The embodiment of the invention provides a message forwarding method and device and relates to the technical field of network communication. The message forwarding method comprises the steps that a first line card obtains to-be-forwarded messages; target switching cards corresponding to the to-be-forwarded messages are determined from at least two switching cards; and the to-be-forwarded messagesare forwarded to a second line card through the target switching cards. According to the method, the corresponding target switching cards are determined according to the to-be-forwarded messages, theattention does not need to be paid to the number of line card interfaces on a network device and items of data streams, the load balancing is easy to realize, the packet loss can be effectively reduced, and the network service quality is improved.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a message forwarding method and device. Background technique [0002] With the rapid development of the Internet and the continuous increase of data services, the process of receiving data streams from one line card of a network device and sending them from another line card has become more and more common. The distributed network device has multiple line cards, and the cross-card output interface of each line card is connected to two switch cards. The data flow between different line cards needs to be processed by the switch card when it is forwarded across the cards. Therefore, the traffic on the line card can be evenly load-shared to the two switch cards for cross-card forwarding, so that the cross-card channel between the line card and the switch card can achieve the maximum utilization rate, reduce packet loss, and improve the cross-card communication o...
