AT&T* has selected Metaswitch’s Perimeta Session Border Controller (SBC) to power a portion of the carrier’s software-centric network as AT&T drives toward its goal to virtualize 75 percent of its network by 2020.

SBCs have historically been hardware-based, rigid and expensive. But the Perimeta SBC will enable AT&T to connect its LTE network traffic with other carriers’ networks via SBCs, which are deployed as virtualized network functions (VNFs). The result is an even more seamless and reliable experience for AT&T customers.

"By embracing VNFs like the Perimeta SBC, AT&T can offer its customers a wide variety of differentiated services on a cost-effective, flexible and programmable network,” said John Lazar, CEO of Metaswitch. "Metaswitch is committed to collaborating with AT&T to deliver agile and high-quality software for AT&T’s software-centric network vision."
