摘要： Apparatus and method are provided for distributing service domain reachability information across domain boundaries, thereby allowing domain management systems to determine routing for cross-domain services even when the domains have different technologies or administrators. A Service Domain Manager within each domain advertises to neighbouring domains which services it supports. A domain which receives such advertisements forwards the advertisement on to other domains. Each SDM builds a routing information table which specifies the service, the domain, the next hop, and optionally user defined metrics. The routing information table does not include end-point addresses, in order to keep the size of the table manageable. In this way, the NMS of each domain obtains an end-to-end view of service routes.
