ZTE has successfully completed the tests on its IP+Optical solutions along with China Mobile. The pilot Projects conducted in five Chinese cities tested the capabilities of ZTE’s SDN based IP+Optical solutions.
ZTE Corporation, a major international provider of telecommunications, enterprise and consumer technology solutions for the Mobile Internet, has designed and developed SDN-based IP+Optical solution, together with China Mobile Research Institute. The solution has passed the SOTN (Software-defined Optical Transport Network) pilot testing held by CMRI (China Mobile Research Institute) in Beijing, Tianjin, Baoding, Cangzhou, and Langfang.
In a press statement issued at its website, ZTE informed that it had covered both IP and optical fields in the pilot testing. ZTE has validated the solution’s capabilities such as IP controller, optical controller synergy, easy IP service provisioning, multi-layer visualization, as well as IP and optical device linking.
The pilot project test results have proven that ZTE’s IP+Optical solution is capable of providing automatic network resource adjustment, which will help operators to reduce the network construction costs and improve O&M efficiency.
In this pilot testing, ZTE has leveraged the advantage of IP+OTN PCE (Path Computation Element) to implement the convenient “one-button” deployment of IP services between routers.
In addition, ZTE’s IP+Optical solution has integrated the originally separated two networks into one topology. The multi-layer network can effectively address the problems of failure display, locating, and service correlation in the existing network.
Furthermore, ZTE has also verified various service linking solutions between IP and optical devices. By activating the G.Hao function, the optical device can work with routers to adjust the bandwidth and implement the MPLS VPN service lossless transport of dozens of Gbits with no packet loss.
Meanwhile, the IP controller can automatically trigger channel adjustment of the OTN device, enabling the optical transport network to dynamically meet requirements of router services in a real-time manner.
ZTE’s IP+Optical solution can improve the network resource utilization and help operators save construction costs by approximately 30% while breaking the boundary between IP and optical transport in their O&M. To some degree, this solution shows a new path to improve O&M efficiency.
