VIAVI Solutions has collaborated with China Mobile Communications Corporation (CMCC) with an aim to introduce 5G services in China by the end of 2019. VIAVI is a preferred vendor of China Mobile, supporting their specific technologies and aggressive roadmap with advanced test solutions. It will provide test and measurement hardware and software for China Mobile and several equipment manufacturers to support development of Slicing Packet Network (SPN) with FlexE interface, the technology the carrier is positioning for 5G transport.
Based on extensive analysis of 5G transport network requirements, CMCC has determined that Slicing Packet Network (SPN) is an optimal technology to support next-generation architecture, bandwidth, traffic model, network slicing, latency and time synchronization. Flexible Ethernet or FlexE is used in conjunction with SPN to create smaller Ethernet channels from a larger one, or vice versa, to guarantee quality of service (QoS) and isolation between slices at the transport layer. CMCC has requested that the ITU (International Telecommunication Union) undertake standardization of SPN. VIAVI is committing to support CMCC by delivering an SPN test platform, establishing a common foundation for network equipment manufacturers, chip developers and transceiver vendors to validate products based on this technology.
In January 2018, Madam Yang Zhiqiang, Deputy General Manager of China Mobile Research Institute (CMRI) welcomed Oleg Khaykin, President and Chief Executive Officer, and Tom Fawcett, Vice President and General Manager, Lab & Production Business Unit, VIAVI Solutions, to her offices for strategic meetings on 5G planning. The CMRI is a technical organization within the CMCC group and is responsible for new technology research, standardization, and qualification of infrastructure equipment-including testing protocols.
