Here's a quick roundup of what went down during the post-holiday week.

Dialogic, a decades-old provider of telecom gear and software, is making its run on network functions virtualization (NFV), starting with BorderNet. Announced July 11, BorderNet is a session border controller (SBC) -- a key element of voice-over-IP (VoIP) deployments -- instantiated in software.  SBCs were integrated into routers in software form a long time ago, so the idea of a virtual SBC isn't all that new, but Dialogic says BorderNet distinguishes itself by being carrier-grade, as opposed to just an enterprise function.

There's something else: Dialogic plans to add software-based transcoding to BorderNet. It's a few months off, planned for the next software release, but it's important because other software-based SBCs are still dependent on a particular digital signal processor (DSP) for media transcoding, according to Tom Schroer, Dialogic's director of service-provider marketing. So, Dialogic sees a chance to take the software SBC a step further.

Rumors circulated last month that EMC had bought this startup for $200 million or $300 million. EMC confirmed the all-cash deal July 11 but didn't disclose the amount.

ScaleIO is a software-defined storage play. Its Elastic Converged Storage builds one storage pool out of various sources including solid-state storage and plain old hard disks. The result is one big, virtual storage-area network (SAN). Zahid Hussein, senior vice president of EMC's flash division, explains more, in print and video form, on the corporate blog.

ScaleIO is a young company, having emerged from stealth late in 2012 with $12 million in venture funding.

Cyan Inc. sells converged packet-optical gear into telecom networks, bundling both traffic types into one management system and control plane in a way that legitimately fits under the SDN umbrella -- although no one called it "SDN" when Cyan launched products in 2009. The company's customer roster on the telecom side is decidedly Tier 2, with names such as Windstream, U.S. Signal, and Great Plains Communications, but that was enough to take Cyan public in May, with revenues that had grown to $95.9 million in 2012 versus $40.4 million in 2011. (Not that Cyan is profitable; 2012 net losses were $16.6 million, or $6.60 per share.)

Anyway. Cyan's latest customer, announced July 11, is Telesystem, a carrier building out Ethernet and optical services in parts of Ohio and Michigan. You might not care right now (Wall Street sure doesn't), but you might want to keep an eye on Cyan, in case the next customer name is one you recognize.
