ZTE helps China Unicom complete optical network services

ZTE Corporation worked with China Unicom to finish the work on the country’s first automatic provisioning of multi-protocol cross-vendor management, as well as control system and multi-scenario end-to-end services, which are all present in the network of China Unicom.   

The international provider of telecommunications, enterprise, and consumer technology solutions for the mobile internet, said in a press release that “this test has verified the automatic service deployment and interface openness of ZTE’s intelligent management and control system ZENIC ONE and put the interoperability and disaggregation of multi-vendor devices in the Optical Network (ON) into practice.”  

During the test, the tool, which is called SD-OTN collaborator and created by China Unicom, had been used in order to connect with the intelligent management and control systems of different vendors, including ZENIC ONE.    

In addition, the partner can acquire intra-domain and cross-vendor inter-domain topology and link resources, as well as creating, and deleting unprotected and protected services transmitted automatically by Optical Channel Data Unit (ODU). 

This can automatically create and delete unprotected and protected services transmitted by Ethernet over OTN (EOO) to allow service bandwidth adjustment on-demand and fault locating.  

As such and while the ON progressively develops, China Unicom aims to achieve ON integration by employing automatic end-to-end cross-vendor service creation in its existing network to deliver better services for its enterprise customers, in order to have the following key technologies that are necessary to adopt:  

-Interoperability of multi-vendor ON devices via the standard Optical Channel Transport Unit k Network-to-Network Interface (OTUk NNI).  

– Design, develop, and deploy a collaborative system with hierarchical architecture.  

 – The way to support orchestration, scheduling, and provisioning of both inter-province and intra-province services of different vendors, is by managing and coordinating the management and control systems from various vendors.  

In this test, the SD-OTN collaborator developed by China Unicom was used to connect with the intelligent management and control systems of different vendors, one of which is ZENIC ONE, the press release added.  

It is worth mentioning that ZTE will keep on helping China Unicom to creatively build ultra-broadband, flexible and high-quality optical networks and expedite network evolution and growth.
