A message processing method and device

Abstract

The embodiment of the present application provides a message processing method and device, the first network device can receive and parse the first message sent by the second network device, and obtain the first sequence number and data message included in the first message, When the first serial number is not less than the expected serial number recorded locally by the first network device and is not greater than the sum of the expected serial number and the preset cache number, if the first network device does not receive the expected serial number and the first serial number All the packets with serial numbers between them, the first network device caches the data packet, records the sequence number of the data packet as the first sequence number, and receives the data packet between the expected sequence number and the first sequence number In the case of packets with all sequence numbers, the buffered packets are sent in order of sequence numbers. The order in which the first network device sends packets is consistent with the order in which the second network device sends packets to the first network device, and furthermore, network service errors can be avoided to a certain extent.

Description

technical field [0001] The present application relates to the technical field of computer networks, and in particular, to a message processing method and device. Background technique [0002] With the continuous expansion of the network scale, in order to ensure the stability of the network and avoid the interruption of the entire network service caused by the failure of a single link, multiple links can usually be deployed in the network. In the related art, the load balancing device can allocate service traffic to each link, so as to realize the load balancing of each link. [0003] In an implementation manner, the load balancing device may forward packets in a packet-by-packet load balancing manner. see figure 1 , a first link 105 and a second link 106 exist between the first load balancing device 101 and the second load balancing device 102 . When the second load balancing device 102 successively receives multiple packets P1, P2, P3 and P4 sent by the second user equi...

Problems solved by technology

[0004] However, due to differences in the performance of packets transmitted by different links, the order in which the first load balancing device 101 receives packets may be inconsistent with the order in which the second load balancing device 102 sends packets, and the first load balancing device 101 follows the Packets are forwarded in the order in which they are received, which may cause errors in network services
