Abstract

The present invention discloses IP message recombination method. Said method includes A, channel selection module less than recombination limitation of length IP slicing retransmission recombination module of recombination equipment, directly transparent transmission retransmission greater than recombination limitation of length IP slicing, transmitting its offset to recombination module for recombination in transparent transmission retransmission just trans- recombination limitation of length IP slicing; B, recombination according to channel selection module retransmitted IP slicing and offset to make recombination, then used as new IP slicing to retransmit. The present invention overcomes current technologic shortage, simplifying IP slicing recombination implementation method, and reducing realizing cost.

Description

technical field

[0001] The present invention relates to the technical field of IP messages, in particular to the fragment reassembly technology of IP messages. Background technique

[0002] Because the Ethernet has the characteristics of low cost, flexible networking and good scalability, more and more IP (Internet Protocol) data is carried on the Ethernet, but because the Ethernet has an upper limit of 1500Byte for the payload length, resulting in When IP packets pass through the Ethernet, the packets that are too long must be fragmented and reassembled.
