While Ethernet technology brings great advantages to the packet transport network, there are some limitations in terms of protection options, traffic engineering and service scalability. These can be addressed by the use of multi-protocol label switching – transport profile (MPLS-TP), which is the transport profile of MPLS, a technology used in the core of the network.

MPLS-TP is fully available within the XTM Series Native Packet Optical 2.0 architecture and the EMXP family of packet optical transport switches. Any physical port on an EMXP can support both native Ethernet and MPLS-TP, allowing operators to deploy MPLS-TP where and when it makes sense for them.

The technology brings a number of advantages to the network operator, including:

  • New protection and restoration schemes that link more closely to reconfigurable optical add-drop multiplexer (ROADM)-based flexible optical networking infrastructure
  • Easy service creation with a similar look and feel to traditional transport networks
  • Advanced traffic engineering and quality of service features
  • Improved service scalability

Of course, as the MPLS-TP services are delivered over the same hardware platform as native Ethernet services, they also benefit from the same transport-like performance with extremely low latency and almost zero jitter, and can be combined with synchronization schemes such as synchronous Ethernet (SyncE) when required, e.g. in mobile backhaul networks.
