Abstract

The invention discloses a method and processing board for processing fragmented messages in network message diverting equipment. The method comprises that an interface board generates a co-processing request message for a fragment stream; and the processing board performs Hash operation according to the co-processing request message, determines a corresponding fragment stream table item, and processes a message to which the fragment stream belongs according to the state of the fragment stream table item and the type of the fragment. The method changes the processing of the message to processing of the co-processing request message so as to effectively solve problems of a waste of storage space and processing time in message diverting in the prior art.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a processing board for realizing fragmented message processing in a network message distribution device. Background technique [0002] With the rapid development of contemporary computer network technology, packet distribution equipment can quickly and accurately distribute massive data packets to various back-end servers for further processing based on the different quintuple information of the packets themselves. Efficient packet distribution equipment is also the basis of other high-level dedicated network equipment (such as firewalls, virtual private networks, load balancing equipment, etc.). [0003] In a network environment, when the length of an IP packet to be transmitted exceeds the Maximum Transmission Unit (MTU), an IP packet will be divided into several IP packets and transmitted separately, which is fragmentation. Fragmented packets occupy a consi...
