About this talk

Next generation packet transport networks (PTN) with a focus on Multi-protocol Label Switching Transport Profile (MPLS-TP) are becoming popular for service providers looking to deploy Software Defined Networks by leveraging OpenFlow and its extensions over a growing diversity of networking systems. One of the largest carriers in the world, CMCC has come up with an overall system specification for its software defined PTN (SPTN) using an OpenFlow southbound interface (SBI). This presentation covers the high level specification and design considerations for a centralized PTN controller and implementing MPLS-TP technologies over OpenFlow in a service provider’s packet transport networks. It will also discuss the TTP extensions, developed by China Mobile and their partners, including key contributor Broadcom, to support this end-to-end use case. The webinar will further discuss the open software developed to run on existing switching silicon which can be deployed in a backhaul network.
