More Operators to Deploy SBCs in Virtualized Environments Going Forward

By Rory Lidstone November 21, 2013

As worldwide user data consumption continues to grow, network operators are realizing the many benefits offered by network functions virtualization in terms of flexibility, cost savings and efficiency. As such, supporting and related technologies are playing an integral role as NFV adoption rises. The session border controller (SBC), for example, is being affected by NFV currently, according to market research firm Infonetics Research.

Indeed, the firm’s latest “SBC Strategies and Vendor Leadership: Global Service Provider Survey,” which provides insights into service provider deployments of SBCs, states that a growing number of operators expect to deploy SBCs in a virtualized environment over the next two years. Companies such as Dialogic have already launched virtualized SBCs in order to cater to this need. Dialogic’s BorderNet Virtualized SBC is meant specifically to address multimedia service deployment challenges.

Furthermore, 85 percent of respondents to the Infonetics survey cite signaling protocol normalization and interworking, as well as session capacity and scalability, as important features offered by SBCs.

“Access at the edge of fixed networks continues to be where the majority of session border controllers (SBCs) are deployed today, but the use of SBCs for interconnection between service providers continues to expand,” said Diane Myers, principal analyst for VoIP, UC, and IMS at Infonetics Research, in a statement. “Wireless access, and specifically voice over LTE (VoLTE), represents solid growth prospects for new SBC deployments over the next two years and is an area where we’re already seeing an impact on sales in the first half of 2013.”

As far as vendors go, respondents generally named Oracle and Acme Packet ahead of the competition in most categories, ahead of Huawei and Sonus Networks, which also ranked well, and Genband. However, Infonetics expects service providers will continue migrating to a multi-vendor strategy over the next two years, so it seems most vendors will still have a place in the market.
