Method for management of a secured transfer session through an address translation device, corresponding server and computer program

摘要

A method is provided for managing a secure session for transporting user packets through an address translation device between a client terminal and a first transport session management server. The session uses a first packet transmission address and at least one second packet transmission address different from the first address. The method includes a step of obtaining, by the first sever, the at least one second packet transmission address from the at least one second transport session management server, so that the client terminal can transfer packets to the first server by using at least the two addresses.

1. A method of traversal of an address translation device in a network comprising:
assigning a first address to a first traversal server, assigning a second address, distinct from the first address, to a second traversal server, obtaining by said first traversal server said second address, and implementing traversal functions by using said first and second addresses, wherein implementing traversal functions comprises: a) upon the first traversal server receiving a request for opening a communication session, performing acts of:
sending, by said first traversal server, a request for opening the communication session to said second traversal server;generating said communication session by said second traversal server;transmission of at least one first piece of information representing said communication session to said first traversal server, by said second traversal server;storage by said first traversal server of said at least one piece of information representing said communication session; andtransmission of at least one second piece of information representing said communications session to a client terminal by said first traversal server, and b) implementing a communication phase using the at least one first and second pieces of information representing said session, comprising:
receiving by said first traversal server a communication request from the client terminal requiring a response from the second address; andtransmitting by the first traversal server a communication request to said second traversal server in such a way that the second traversal server sends the response to said client terminal.
