ZTE SDON controller solution completes OIF/ONF interoperability testing
Announced Date: 10/9/2014 Published Date: 10/13/2014

ZTE announced that its new software-defined optical network (SDON) controller solution has successfully completed the global interoperability test of the Open Internetworking Forum (OIF) and Open Networking Foundation (ONF).

The new ZTE SDON controller, based on an advanced elastic network control architecture and offering compliance with the latest industry standards, demonstrated it could enable operators to manage their networks with greater openness and improved flexibility and coordination.

Through the integration of OTN technology and the SDN architecture, ZTE's SDON controller provides open support to upper-level multi-domain controller/service orchestrator and applications, while simultaneously enabling centralised control of hierarchical network interoperability. The new solution utilises ZTE's PCE (path computation element) control solution for optical transport networks, which debuted in 2013.

Hosted in the laboratories of TELUS, Verizon, Deutsche Telekom, China Mobile and China Telecom, the Transport SDN tests recently carried out by the OIF and ONF involved nine solution vendors. The tests demonstrated the interoperability of cross-regional and multi-vendor bandwidth-on-demand (BoD) services, more dynamic network adaptability, improved network O&M efficiency and the potential for reduced operating expense for operators.

In the tests, ZTE's SDON controller also showed flexible support for open interfaces, such as Openflow and RESTful CVNI (control virtual network interface) and CDPI (control data plane interface).

ZTE’s SDON solution is designed to enable the evolution to next-generation networks while helping operators protect their existing network investments as they build out future-oriented smart, efficient, open optical networks.

ZTE stated that to develop the SDON technology it will focus on areas including: centralised network control and management to improve O&M efficiency; increasing network flexibility and optimising resource utilisation; delivering open network resources to allow service innovation, fast deployment and an enhanced user experience.
