| 摘要 |
The invention relates to a method for emulating a multipath connection, in which the data packets transmitted or received by a given client device are intercepted by a plurality of concentrators located in at least one network to which said client device is connected, each concentrator making it possible to aggregate connections using a plurality of paths usable by the client device. According to the invention one of said concentrators is dynamically designated as the "main concentrator" and the other concentrator or concentrators as the "secondary concentrators"; moreover, said main concentrator or a secondary concentrator: a) receives a data packet transmitted by the client device to a correspondent; b) if applicable, removes all the multipath options from the received packet; c) replaces the source address of the received packet with an address of the main concentrator; and d) sends the packet modified in this way to said correspondent. The invention can be used in the MPTCP (Multi-Path TCP) protocol. |
