SHENZHEN, China -- Huawei, a leading global information and communications technology (ICT) solutions provider, today announced the successful demonstration of Ethernet-over-OTN interoperability tests with Deutsche Telekom (DT) and KDDI R&D Laboratories Inc. (KDDI Labs). The tests were conducted by the Optical Internetworking Forum (OIF) to showcase the multi-vendor interoperability of Ethernet services in a multi-carrier environment over OTN transport. The demonstration focused on both data and control plane technology.

The DT and KDDI labs test networks employed Huawei’s terabit OSN product, which is capable of providing OTN and data solutions for future transport networks. The tests involved GE/10GE EPL/EVPL service interoperability, ODUk/ODUflex mapping and encapsulation, ODUk/ODUflex overhead interoperability, ODUk SNCP cross-domain protection, and OTUk ENNI interoperability.

The integration of GMPLS/ASON control plane features into OTN results in greater bandwidth efficiency, simplified O&M, faster service provisioning, and enhanced network reliability. Huawei takes the lead in unveiling an OTN solution that supports GMPLS/ASON control plane features at both the optical and electrical layers. Huawei has deployed over 70 commercial OTN GMPLS/ASON networks worldwide.
