The OpenStack Foundation today released a report with summaries of what some service providers are doing with OpenStack to advance their network functions virtualization (NFV) goals. The SPs include NTT Communications, Deutsche Telekom, SK Telecom, AT&T, and Verizon.
OpenStack software is playing an integral role in NFV development efforts, particularly in conjunction with ETSI NFV and OPNFV.
OpenStack for NFV will be production ready in 2016, according to the OpenStack Foundation Report, “Accelerating NFV Delivery with OpenStack.”
The report says NTT Communications deployed a large proof-of-concept built with the same architecture and topology as its commercial ISP backbone and cloud services. NTT then tested OpenStack as a virtualized infrastructure manager (VIM). It also compared some commercial NFV MANO software with OpenStack’s MANO components — NFV orchestrator and VNF manager.
South Korea’s SK Telecom has an endgame to operate all of its telecom network functions in its software-defined data center, where all components will be running as virtual network functions (VNFs) on OpenStack cloud infrastructure. SK Telecom is first focusing on virtualization of IMS and EPC functions. It has succeeded in deploying parts of its IMS services as virtual IMS (vIMS) in its commercial operation environment with OpenStack.
Deutsche Telekom is in the process of transforming its European network to all-IP so that it’s easier to virtualize services. Its first production NFV workload running OpenStack is a cloud VPN service available in Croatia, Slovakia, and Hungary.
AT&T’s Integrated Cloud (AIC) is based on OpenStack. By 2020, AT&T plans to virtualize more than 75 percent of its network.
Verizon is building a companywide OpenStack platform for running VNFs as well as other internal applications. Verizon’s test lab is built on Kilo, the second-most recent OpenStack release behind Liberty.
