Metaswitch Demonstrates PCE-Based Software Defined Networking Interoperability

PCE provides an evolutionary approach to SDN, increases flexibility, performance and simplifies operations


MPLS & Ethernet World Congress, Paris, February 7, 2012 — Metaswitch Network Technologies today announced it has successfully completed interoperability tests of its PCE solutions at the MPLS & Ethernet interoperability event at the MPLS & Ethernet World Congress, organized by EANTC (European Advanced Networking Test Center). Path Computation Element (PCE) is an architecture standardized by the IETF and enables the ability to migrate the path computation function from the network to the cloud, a standalone server or a network management system.

"PCE provides network operators with an evolutionary path to Software Defined Networking (SDN). This is a preferred solution for carriers with massive installed base of equipment and legacy services as it provides a non-disruptive, gradual migration to SDN," said Clive Partridge, general manager of Metaswitch's Network Technologies. "We are showcasing a range of PCE functionality including interoperability with a leading routing vendor, which confirms that our PCE-based SDN solutions are ready for production-based carrier environments."

SDN provides operators with many advantages including increased flexibility and performance along with simplified operations. PCE achieves this by migrating path control to a centralized role while leaving the majority of field-hardened networking functions untouched. This approach significantly reduces costs and risk and is less disruptive than alternative SDN approaches.

Metaswitch's PCE solution, DC-PCE, is fully portable software designed for system vendors of carrier equipment and OSS systems. DC-PCE is pre-integrated and backwards compatible with Metaswitch’s widely deployed control plane software, enabling network OEMs to roll out SDN solutions in a quick and cost-effective manner.
