- Abstract
- In a Next-Generation Network (NGN), CPEs which have path-coupled signalling capabilities are being incorporated. Currently, path-coupled signalling technologies such as RSVP and GPRS Session Management Signalling are being used. As the signalling technologies requires an end-to-end path to be established which guarantees a set of QoS parameters, MPLS has been used traditionally in the IP-based core network to provide a virtual end-to-end path, and that means there should be one LSP need to be setup per each path reservation request. Though, this simple scheme does not scale well in the core network. As there can be millions of CPEs attached to the core network through access networks, we need a different method to achieve scalability. In this paper, we suggest scalable method to integrate paths established by heterogeneous path-coupled signalling messages into a MPLS-based core network. With this method, we believe that the scalability problem of the core networks of NGN shall be resolved.
