Open service discovery and routing mechanism for configuringcross-domain telecommunication services

The invention claims a surmounted the edge domain service distributing and accessibility information in a communication network device and method, thereby when with different technique or a manager the domain, is a domain management system and route of cross-domain service. The service and managing each and neighborhood round to the service is a supporting. Receiving the circular the set is electrically connected with the circular transmitting the domain. The SDM a routing information platform, the table distributed standard of user definition service and domain, a jumped and a second. The routing information table except the vertex address, a conveniently of the size of the table is easy for. , Wherein each territory's NMS obtaining to serving power the end-to-end situation.
