P-OTS, or packet-optical transport systems, were introduced to the market a few years ago. These products were created to meet the requirements of operators trying to cope with massive amounts of data traffic. The goal was to make transport networks more supportive of data services, more resilient, more manageable and more cost-effective. But have the systems lived up to expectations? Are they meeting operators’ goals for next-generation transport?
Infrastructure vendors approached the development of their P-OTS platforms in a variety of ways. Some just added data switches on a blade next to the central SONET/SDH cross-connect. Others utilized dual fabrics, hybrid fabrics or unified fabrics that supported Ethernet and ODU/SONET/SDH cross-connect functionality. Still others added ROADM capabilities to their routers or simply added OTN mapping to CESR 10GbE line interfaces. And more recently, many vendors have taken the approach of integrating various combinations of WDM, SONET/SDH and data switching functions, along with ODU switching capabilities and GMPLS control planes.
