In recent years, the telecommunications industry has looked toward Network Function Virtualization (NFV) to revolutionize the way that telco services are developed and delivered to customers. A "network function" is any service that acts on the data passing through the network. In the typical datacenter, this would include services like a firewall, a VPN endpoint, or an intrusion detection system. In the telco industry, network functions also cover voice, data and internet services, broadband and cellular network services, and the delivery of video content, such as streaming TV.
Traditionally these network services have been provided by big, expensive, custom-built servers that require a multi-year investment for the network operators, so progress tends to be in fits and starts because previous investments are amortized before replacement features are deployed.
By moving the operation of these network services to virtual network functions (VNFs) running on a private cloud platform, on industry standard high-density servers, NFV enables operators to deliver customer-facing services more easily and faster. DevOps can finally come to the deployment of network services.
The Open Platform for NFV (OPNFV) project launched earlier today on opnfv.org as an industry-wide effort that includes network operators, network equipment providers, platform vendors, and hardware vendors working together to create a reference platform for NFV. The goal is to take existing open source projects such as OpenStack, OpenDaylight, DPDK, libvirt, and KVM, and identify any areas where we can improve these platforms to enable the deployment of network services.
As a founding member of the project at the highest Platinum level, Red Hat recognizes the project’s potential to change the telco industry, and is committed to bringing the company’s strengths to the table in support. One of the key challenges for the project will be to ensure that code developed for NFV is submitted and accepted upstream in the relevant projects, and Red Hat has a wealth of experience upstream in these communities and in affecting change across a number of projects.
