Method of taking account of quality of service between distinct IP telephony domains, and a corresponding location server and computer program

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.

1. A method comprising:
propagating at least one route for at least one digital stream between a first location server suitable for managing locations of clients of a first IP telephony domain and a second location server suitable for managing locations of clients of a second IP telephony domain, which is distinct from said first IP telephony domain, wherein the first and second location servers reside on a telephony domain service layer, said first location server belonging to a first autonomous system and said second location server belonging to a second autonomous system, which is distinct from said first autonomous system, wherein the first and second autonomous systems reside on an IP transport layer, which is distinct from the telephony domain service layer, said propagating comprising: a step of sending digital stream routing update messages on said telephony domain service layer, from said first location server to said second location server, wherein said update messages contain information for managing quality of service, which comprises the following:
information about a quality of service component associated with at least one autonomous system on the IP transport layer, referred to as a system component; andinformation about a quality of service component associated with at least one IP telephony domain on the telephony domain service layer, referred to as a telephony domain component; and prior to being propagated towards said second location server, said first location server updates the information for managing quality of service to include further information about:
quality of service relating to the first IP telephony domain on the telephony domain service layer; andquality of service relating to the first autonomous system on the IP transport layer.
