Abstract

The invention discloses a message forwarding method and device, and the method comprises the steps: determining a fragmentation type corresponding to a fragmentation message for each fragmentation message; and if it is determined that the fragmented message is the first fragmented message, determining a storage address corresponding to the fragmented message according to the basic message data carried in the fragmented message and storing the storage address; if the fragmented message is determined to be a subsequent fragmented message, determining a storage address of a first fragmentation message corresponding to the fragmentation message as a target storage address according to the basic message data carried in the fragmentation message, and forwarding the fragmentation message according to a message destination port carried in the first fragmentation message corresponding to the fragmentation message inquired from the target storage address. Since the basic message data of the subsequent fragmented message is the same as the basic message data of the corresponding first fragmented message, the message destination port of the first fragmented message corresponding to the subsequent fragmented message can be queried according to the basic message data, so that the subsequent fragmented message can be correctly forwarded.

Description

technical field [0001] This specification relates to the field of computers, and in particular to a method and device for message forwarding. Background technique [0002] In network information transmission, if the packet length of the network layer exceeds the maximum number of transmission units limited by the data link layer, the packet needs to be fragmented. However, after a packet is fragmented, only the first fragmented packet at the header contains the destination port of the packet, while the subsequent fragmented packets lack the destination port of the packet, so that the subsequent fragmented packets cannot be forwarded to the corresponding in the business server. [0003] In the prior art, the service platform can only receive the first fragmented message, but cannot receive subsequent fragmented messages. For such a situation, the service platform can associate the first fragmented message with the same destination IP address with the subsequent fragmented m...
