Title: METHOD OF SPLITTING APPLICATION MESSAGES IN AN IP NETWORK
Abstract:
The invention relates to a method for splitting application messages in an IP (Internet Protocol) network, comprising the following steps: a) a node of the IP network, termed the first node, receives a message having to be transmitted to another node of the IP network, termed the second node; b) said first node compares the length of said message with the maximum transmission size MTU (Maximum Transmission Unit) characterizing the path between said first node and said second node; and, if said length is greater than the MTU, c) the first node splits the message into at least two segments, and inserts each respective segment into a respective data packet of length less than or equal to the MTU; d) the first node transmits said data packets to the second node; and e) the second node assembles said segments so as to reconstruct said message. Said method is noteworthy in that, said message being an application message: during said step c), the first node inserts into each of said data packets a so-called positioning information item specifying the relative position in the message of the segment inserted into this data packet; and during said step e), the second node reconstructs the message with the aid of said positioning information items. Application to IP networks using a non-connected transport protocol such as the UDP protocol.
