Research output: Contribution to conferencePaperpeer-review


This paper focuses on providing technical solutions to the multiprotocol label switching (MPLS) label distribution protocol (LDP) signaling when interoperating with the asynchronous transfer mode (ATM) private network-to-network interface (PNNI) and compares this with the interoperating procedures of the user network interfaces (UNI) topology. This paper proposes procedural operations that are necessary for interoperability of both of these networking architectures. Interoperability enhancement options are focused on managing quality of service (QoS) and traffic management support for applying loosely explicitly routed LDP and strictly explicitly routed LDP. The paper also investigates procedure for assigning the proper class to the supported differentiated services (Diff-Serv) for MPLS label switching routers (LSRs).
