Could use some 5G slices after that
DoCoMo has signed up to a course of Nokia routing exercises to strengthen its core and its transport functions and has announced to its partners that will more than ready for some 5G slices. The Finnish equipment maker Nokia has announced that it will work on the core of top tier Japanese telco NTT DoCoMo’s nationwide IP core backbone. Nokia will configure it in readiness for dynamic allocation of bandwidth, through transport network slicing as it rolls out new 5G mobile services. The upgrade will empower it to give much more detailed and accurate service level agreements, which could make it a better network for network service suppliers and content providers to do business with. Alongside these granular SLAs the sliceable network offers greater capacity and versatility, automatically adjusting to whatever demands. The regulated supply also improves power and resource efficiency.
DoCoMo has deployed Nokia’s 7750 SR-14s core routers, powered by its FP routing silicon. The FP5 line cards, which prepare it for tomorrow’s demands for 800GE capacity, will triple throughput with a 75% power savings on previous generations of kit. They save time too by easing the network’s evolution with concurrent line rate FP4 and FP5 line card operation in the same system. This will extend the life and sustainability of the systems as DoCoMo customer bandwidth needs increase in the future.
Nokia claims it will simplify the network’s evolution through the segment routing sensibilities of its Service Router Operating System (SR OS) for traffic engineered network slices for the granular SLAs required by DoCoMo’s customers. Nokia’s NSP complements the telco’s segment routing with a Path Computation Engine (PCE) that use instant telemetry to automatically optimize the IP network and stick to its SLA promises. NSP can automate the creation, assurance and optimisation of IETF standards-based network slices in the transport domain.
“DoCoMo is committed to slicing in 5G networks to [flex up] the network and meet the diverse needs of our customers,” Fumitaka Murayama, General Manager of Core Network Engineering Department, NTT Docomo, “it was essential to use Nokia’s IP core create new value for customers through network slicing.” This network will provide that Nokia’s 7750 SR-s platform and NSP can do that, however unpredictably the needs of the customers change, “for years to come,” said John Lancaster-Lennox, Head of Market Unit Japan at Nokia.
