OREANDA-NEWS. July 01, 2015. Huawei has successfully demonstrated its next-generation user-oriented Software-defined Networking (SDN), NEMO (NEtwork MOdeling) language during the Open Networking Summit 2015 in California, the United States.

NEMO facilitates enterprise users and over-the-top providers with deploying desired scenarios without the need for complex SDN North-bound Interfaces (NBI) or network implementation and deployment details. Through eliminating service complexity caused by diverse devices, NEMO enables the SDN controller to automatically allocate network resources, provision services, and resolve conflicts between network resources and services.

Traditional SDN controller NBIs uses a bottom-up design approach, and focuses on network configuration and implementation details, resulting in a series of problems including complicated network interfaces. NEMO, which uses a top-down design approach, focuses on users' operation and application needs, resulting in a user friendly system. Users describe their network needs which are also identified by using NEMO, and SDN controllers are able to automatically implement complex operations such as resource allocation and network performance monitoring. The solution translates users' service behaviors on the network into operations on network objects through NEMO's modeling and network programming capabilities. These come from abstracting and summarizing network capabilities and resources.

To date, Huawei has actively supported and promoted the commercial use of SDN/NFV in existing operator networks. Over the next few years, Huawei aims to build future-ready, automated and virtualized network architecture, and drive service innovation, implement agile services and deliver on-demand networks.
