MPLS-TP: Packet Transport Network Enabling Technology
The growing demand for bandwidth seems like a never ending story. Driven by the richness of content in vertical markets like broadband residential access and cellular, operators and telecoms vendors alike are constantly looking for ways to convert networks into more scalable and efficient packet-based transport networks.
- Cost effectiveness: This can be achieved by using Layer 1 and Layer 2 protocols for simplified operation, unified management and control across packets.
- Network scalability: The ability to support larger numbers of clients and larger amounts of data end-to-end.
- Carrier multi-play: This refers to the ability to support multiple types of clients, with the built-in ability to differentiate between them upon need while preserving QoS.
- End-to-end reliability: Carriers must be able to have end-to-end visibility of their networks, including passive monitoring and active fault prevention. This is accomplished through the use of OAM flows.
MPLS-TP is enabling next-generation packet-based networks by linking the transport capabilities (brought from TDM transport to the Ethernet world) together with the service provisioning and management of TDM transport. Without getting too deep into the details, it can be said that MPLS-TP-based architectures empower transport networks by offering cost-effective and ease-of-use management. In recent years, we’ve seen several deployments of MPLS-TP where operators have added new packet-based services while reducing costs significantly. Operators have also been utilizing MPLS-TP for the aggregation of traffic originating from the boundaries of the network, migrating their TDM-based networks to packet-based networks without losing functionality.
