Abstract

See full text

A mechanism is provided for a non-converged network for a service provider. A core network is divided into individually managed domains, where each of the domains comprises multiprotocol label switching for packets. A management system is coupled to each of the domains. Network elements in each of the domains are restricted from directly transferring packets to network elements in another one of domains. Each of the domains has a domain firewall at an edge of the domains, and the domain firewall restricts packets from being received from other domains. To transfer packets from one domain to another domain, the management system receives the packets from one domain and transfers the packets to the other domain after authentication.
