The Nordic telecommunications provider TeliaSonera will use Metaswitch’s session border controller (SBC) software Perimeta and run it on commercial off the shelf (COTS) servers, the vendor is announcing today.

Perimeta is a network functions virtualization (NFV)-capable, carrier-class SBC. It has already been deployed as a virtual network function (VNF) in several carrier networks, and it operates in all environments — hypervisors, private, and public clouds.

Because Perimeta was architected as a pure software session border controller, it can run on an ATCA chassis and on COTS server platforms from the likes of Dell, Cisco, and HP. This is appealing to service providers interested in creating and managing SBCs through a farm of cheaper commodity servers.

That was what TeliaSonera was in the market for.

"Proven software on common off-the-shelf hardware was definitely the winning proposition for our selection,” said Micaela Giuhat, a senior vice president of product marketing at Metaswitch.

The TeliaSonera deal builds on earlier announcements of service providers using Perimeta, most notably AT&T but also Spark New Zealand, TelAlaska, Telekom Austria’s Vip Mobile, BT One Phone, and Tiscali.
