Abstract
The invention consists in implanting an encapsulation mechanism (ME) in an operator access router, whereby said encapsulation mechanism can calculate a header for messages that the transmitter site (B1) wishes to send to the receiver site (Bn′), said header containing at least one prefix concerning the service provided by the operator, a virtual private network identifier (VPNB), a destination site (Bn′) network prefix and a suffix which consists of a field of bits which can assume any particular value.
Claims11
A method for interconnecting virtual private networks in non-connected mode, so as to provide transmission of messages between interfaces of routers in order to transport data between a transmitter site and a receiver site, via an access router of an operator, said method consisting of setting up in this router or via a customer access router an encapsulation mechanism suited to calculate a header for the messages that the transmitter site wishes to send to the receiver site, this header comprising at least one prefix relating to the service provided by the operator, a virtual private network identifier, a network prefix of the destination site, and a suffix which consists of a field of bits which may assume any value.
