5G Deployment Accelerates NFV Evolution
By the year 2024, 5G networks will carry 25% of the mobile data traffic across the United States, 70% of which will be driven solely by video, according to The Linux Foundation. With that shift facing the industry, the question is: “What must happen to make this prediction a reality?”
self-driving networks creation
The general consensus amongst attendees during the Linux Foundation’s Open Networking Summit (ONS) keynote from AT&T CTO Andre Fuetsch is to create a self-driving network with high degrees of orchestration. Automating the onboarding and operations of virtual functions is needed to support the speed and flexibility that will help drive 5G deployments.
Consider that AT&T, for instance, is now launching in 12 5G US cities and planning a nationwide 5G network by early 2020. That is expected to result in a 3x increase in Global IP traffic, 7x increase in Mobile IP traffic and 71% traffic from wireless devices. The increased demands on the network caused by a rollout of this magnitude will require service providers to be ever more efficient and agile in their CapEx and OpEx spending.
open source platforms adoption
AT&T has been pioneering an open source approach for network function virtualization (NFV)/software-defined networking (SDN). The multinational conglomerate created open source Enhanced Control, Orchestration, Management and Policy (ECOMP) for product/service independent capabilities for the design, creation and life cycle management of carrier grade, real-time workloads. China Mobile created Open-Orchestrator (Open-O) with a similar intent.
The Open Network Automation Platform (ONAP) is an initiative created by the combination of the ECOMP and Open-O projects to bring the capabilities for designing, creating, orchestrating and handling the full lifecycle management of the Virtual Network Functions (VNF), Software Defined Networks and services. Chris Rice, SVP, AT&T Labs, Network Cloud and Infrastructure, said, “We’re certainly going to get help from the rest of the ecosystem and the vendors but [the ONAP initiative] is something that’s really going to affect the way that we build networks in a software-defined way going forward.”
During the summit, Fuetsch noted that the security, transparency and interoperability that open source provides makes it the preferred option for service providers. LFN General Manager, Arpit Joshpura, shared the following survey results on the key motivations for the service provider to go open source. Service provider adoption of open source is driven because of its:
The industry-wide momentum continues to grow in anticipation of the new Dublin Release of Standards, in which iconectiv contributed insights that will help accelerate VNF onboarding.
