Embodiment Construction

[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] image 3 A flow chart for reassembling fragmented packets provided by Embodiment 1 of the present invention, such as image 3 As shown, the specific steps are as follows:

[0046] Step 301: Configure the same recombination interface board selection principle on each interface board of the receiving device.

[0047] The selection principle of the reassembly interface board can be: among all the interface boards that may receive fragments, use the interface board with the smallest board number as the reassembly interface board; or, among all the interface boards that may receive fragments, use the interface board with the smallest load The interface board is used as a reconfiguration interface board. At this time, the main control board needs to periodically send the load information of all interface boards to each interface boar...

Abstract

The invention discloses a fragment message reconstructing method, comprising: configuring the same reconstructing interface board selecting rules on each interface board of a receiver in advance, when an interface board of the receiver receives a fragment, the interface board determines all the interface boards that all the other fragments may reach, where these fragments belong to the same message, according to the reconstructing interface board selecting rules, selecting an interface board from the determined interface board as a reconstructing interface board, and sending the received fragment to the reconstructing interface board for reconstructing. And the invention discloses an interface board, comprising: fragment receiver module and reconstructing interface board determining module. And the invention makes fragments of different messages able to be dispersed to different interface boards for reconstructing, largely speeding up message reconstruction and reducing the burden on the master control board.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a fragmented message recombination method and an interface board. Background technique [0002] Fragmented packets are very common packets in Internet Protocol (IP) networks. When the packet length exceeds the maximum sending unit of the interface, the packet must be fragmented and then sent through the interface; when the packet reaches the destination address, the destination device is responsible for collecting all the fragments of the packet and The offset of the text is reorganized and restored to its original state. [0003] In a distributed environment, for packets that are not transmitted in load sharing mode, the packets will be concentrated on one interface to reach the destination device; while for packets transmitted in load sharing mode, the packets may be dispersed in different interfaces to reach the destination device . [0004] A distributed environm...
