Viavi Solutions has announced a collaboration with China Mobile to help the operator introduce 5G services in China by the end of 2019 in part by helping the cellco to develop its packet slicing transport technology.
Viavi 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 China Mobile is developing for 5G transport.
China Mobile says SPN is an optimal technology to support next-generation architecture, bandwidth, traffic model, network slicing, latency and time synchronization. Flexible Ethernet (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. China Mobile said it has requested that the ITU undertake standardization of SPN.
Viavi is committing to support China Mobile’s effort 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 order to realize China Mobile’s vision of introducing 5G service by the end of 2019, principal technologies including SPN for transport must be standardized by the ITU-T,” said Oleg Khaykin, president and chief executive officer. “We have advanced our test technology to meet this objective, and our solutions are ready to support the China Mobile ecosystem of partners to deliver interoperable network infrastructure.”
