摘要:
A method of receiving an IPv6 data packet in an IPv6 domain connected to an IPv4 domain, said packet comprising an IPv6 destination address and an IPv6 source address. The method comprises the following steps: identifying an IPv6 destination address constructed by concatenating an operator prefix, an IPv4 destination address, and a destination port number; if necessary, regularizing at least one address of the data packet and modifying the data packet; and routing the modified data packet to its destination.

A method of receiving a data packet from an IPv4 domain in an IPv6 domain, said data packet comprising an IPv4 destination address and a destination port number. The method comprises the following steps: constructing an IPv6 destination address by concatenating an operator prefix, said IPv4 address, and the destination port number; generating an IPv6 data packet from the IPv6 constructed destination address and the received IPv4 data packet; and routing the generated IPv6 data packet in the IPv6 domain using the IPv6 constructed destination address, said constructed address belonging to a range of IPv6 addresses routable to an interconnection equipment of the IPv6 domain with the IPv4 destination address.

摘要:
A method of routing a data packet in a telecommunications network, said packet comprising a primary destination address and a destination port number. On reception of said packet, the following steps are executed: determining a port mask defining a range of port numbers to which the destination port number belongs; selecting an identifier of a destination piece of equipment of the packet from a plurality of equipment identifiers associated with said destination address on the basis of the port mask; and routing the packet to the destination piece of equipment on the basis of said identifier.

A method is provided for propagating at least one route for at least one digital stream between a first location server of a first IP telephony domain and a second location server of a second IP telephony domain, the first location server belonging to an autonomous system, and the route for transferring the at least one digital stream. The method includes a stage of propagating at least one identification relating to the autonomous system of the first location server towards the second server.
摘要:
A method is provided for selecting a telephony route for at least one digital stream serving a telephony destination. The method is performed within a first location server belonging to a first IP telephony domain deployed on at least one autonomous system. The autonomous system exchanges IP routing information with its neighbors designating at least one IP destination for updating an IP routing table. The method includes: the first location server searching for the IP routing information, the IP routing information including an identifier of a second IP telephony domain having associated therewith the at least one IP telephony destination, referred to as the destination identifier; and selecting the IP telephony route to reach the at least one telephony destination, applying a predetermined criterion for selecting the second telephony domain as a function of the destination identifier.
摘要:
A method for propagating at least one route for at least one digital stream between a first location server of a first IP telephony domain and a second location server of a second IP telephony domain. The first location server belongs to a first autonomous system and the second location server belongs to a second autonomous system. The method includes sending digital stream routing update messages to the second location server. The update messages contain information for managing quality of service, and, prior to being propagated towards the second server, the information is updated by the first server. The information includes at least one of the following: information about a quality of service component associated with at least one autonomous system, referred to as a system component; and information about a quality of service component associated with at least one IP telephony domain, referred to as a domain component.
摘要:
In a network (10) providing a service to a client of a terminal (T1) and comprising at lease first and second session border controllers (A, B), at least one identical address (@Ain) is allocated to the first and second session border controllers. A router (Ra) connects the terminal (T1) to the first session border controller (A) and is capable of dynamically managing a routing table indicating at least first and second routes for the address. A message transmitted from the terminal to the network is received at the first session border controller when the router selects the first route and at the second session border controller when the router selects the second route.

A method of transmitting data between nodes of a network, a node being attached to an IP environment calls its source environment. This method comprises a step of assigning a user agent included in one of said nodes, a fake address in an IP environment different from that of said source environment; and a step of presenting said fake address and a source address of said user agent in said source environment when setting up communication with a remote node.
