VIAVI Solutions, as per the mobile technology agreement, will provide test and measurement hardware and software for China Mobile and several equipment manufacturers to support the development of Slicing Packet Network (SPN) with FlexE interface.

China Mobile decided to opt for Slicing Packet Network (SPN) as the optimal technology to support next-generation architecture, bandwidth, traffic model, network slicing, latency and time synchronization.

China Mobile will use Flexible Ethernet or FlexE 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.

VIAVI Solutions is committing to support China Mobile 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.

“To realize China Mobile’s vision of introducing 5G service in 2019, principal technologies including SPN for transport must be standardized by the ITU-T. We have advanced our test technology to meet this objective, and our solutions are ready to support the China Mobile’s partners to deliver interoperable network infrastructure,” VIAVI Solutions CEO Oleg Khaykin said.
