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:
A method of sending data between heterogeneous nodes. The method includes a step of inserting a type indicator into a message (RE(1), I(1)) sent by a user agent in one of said nodes before setting up a communications session between said nodes, said type indicator representing the type of address associated with said user agent (A). The method quickly identifies risks of incompatibility between the types of two user agents (A, B) seeking to communicate with each other, with a view to resolving such incompatibilities if necessary. Application to intercommunication of IPv4, IPv6 or Dual Stack (DS) user agents in IP networks.

A service is provided to a user of a terminal in a network, comprising a service platform and network equipment including session border controllers. Each of the controllers is capable of communicating with the service platform. At least one given session border controller is capable of routing messages received from the terminal, intended for the service platform. This controller decides that the service platform is not accessible on the basis of an accessibility check (302) and then operates in an autonomous operating mode (303, 310) according to which the controller selects a network equipment separate from the service platform and routes at least one message received from the terminal to said selected network equipment.
摘要:
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.
摘要:
A method and apparatus are provided for optimizing routing of communications between a plurality of telephony domains. The method includes: detecting a congestion or congestion-risk phenomenon in a first telephony domain; and a phase for transmitting, in a signalling message, at least one information concerning the congestion or congestion-risk phenomenon, or congestion information, to at least a second telephony domain.

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 SIP server addressing method for the inter-operation of SIP nodes (A, B) of a determined IP type in which each SIP server (P, R) is attributed (A) an auxiliary address (R2@v4, P2@v4) of the same IP type as their original address (R1@v4, P1@v4), wherein the auxiliary address corresponds to a distinct IP type communication address, all SIP nodes of the same IP type as this SIP server are supplied (B) with the original address, and to all SIP nodes with an IP type distinct from the IP type of this SIP server, this communication address and the communication address of one of the IP types is translated (C) into the auxiliary address, of the same IP type as the IP type of the original 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.
摘要:
A method is provided for propagating routes between a first location server of a first IP telephony domain and a second location server of a second IP telephony domain. The method includes the following stages: the first location server receives a first propagation message from at least one neighboring location server and containing at least two routes enabling a destination to be reached, referred to as propagation routes; and the first location server advertises the at least two routes to at least one second location server of a second telephony domain neighboring the first.
