Data stream routing system for e.g. core network, has node comprising service module, transfer gateways and LOC function that is intended for producing routing table for each service, which is exploited upon request from service module

摘要

The system has a node, in a transport network, comprising a service module (xSVA - xSVG), transfer gateways (xTG 11-xTG 14, xTG 21, xTG 22, xTG 31, xTG 32) and a LOC function that is intended for producing a routing table for each service, which is exploited upon request from the service module. A LOC server is connected, for a given service, to other LOC modules through a service group node. An independent claim is also included for a method for routing multiple-topology and service on a transport network.
