While much of the technology news this week has been dominated by data center announcements, there is more to IT than software-defined networks. This week, session border controller vendor Sonus announced the version 4.0 release of its flagship SBC 5000 product line.
The 4.0 release gives the SBC a more significant role than it has had in the past. Historically, as the name might imply, an SBC is used at the border of networks to manage and secure IP sessions. Sonus is now positioning the SBC as an internal device that controls traffic moving across network boundaries, as well as traffic moving within the enterprise network. This means being the control element for LAN, WAN, off-net and mobile traffic.
Additionally, most engineers consider the SBC to be a device that manages voice traffic only. Sonus now wants the SBC to handle all types of multimedia traffic, particularly video. The emphasis on video certainly doesn’t imply that video is more important than voice, chat or other collaborative applications. It’s just that video is a beast to manage because of the amount of bandwidth it generates. The Buggles wrote a song in the 80s called “Video Killed the Radio Star,” but in IT video kills the corporate network, if not managed correctly.
