(IS-2014-82) Converging the optical core to IP

Building a common network infrastructure that’s constructed with a mix of Ethernet, IP/MPLS, and DWDM may be an ultimate goal for traditional and competitive service providers, but the reality is that there are various ways to get there. At the heart of this concept is the emergence of the Packet Optical Transport System (P-OTS). While definitions vary, P-OTS is a transport solution that supports a mix of DWDM, SONET/ SDH, Optical Transport Network (OTN), and Ethernet switching capabilities. Various aspect of converging multiple transport protocols on a single optical network are discussed, including technical issues and ways to address them.
