Metaswitch Expands OEM Solutions With Another Optical Industry First

Metaswitch Delivers the Industry's First Portable Protocol Solutions for G.709 OTN

LONDON--(Marketwire - April 12, 2010) -  Metaswitch has built upon its market leadership position in offering technology solutions to manufacturers of networking equipment by delivering the industry's first portable protocol solution for signaling and routing in G.709 Optical Transport Networks (OTN). OTN provides a transparent, hierarchical network that supports the transport of both packet and optical traffic, greatly increasing network efficiencies. Metaswitch delivers standards-based OTN extensions of its Integrated Control Plane software to enable system vendors to dynamically signal and route connections in an OTN network.

The advent of Metaswitch's portable OTN software solution is well timed as many equipment vendors are rolling out hybrid Packet-Optical Transport Systems (POTS). The availability of a fully integrated control plane for these systems will enable service providers to offer a diverse set of packet, ethernet and optical services while greatly improving operational efficiencies.

With this announcement Metaswitch is continuing its leadership as a provider of portable protocol solutions to manufacturers of communications equipment. Metaswitch's support for OTN is the latest in a string of optical industry firsts from the company, going back to 2001 with the introduction of the industry's first portable protocol solutions for GMPLS and OIF UNI, closely followed by innovations in LMP (2002), and e2e LSP (2008).

The OTN is largely defined in the ITU's G.709 and G.872 specifications and in IETF RFC 4328. Metaswitch's portable control plane solution for G.709 OTN is delivered as extensions to the company's widely deployed DC-RSVP MPLS signaling software and DC-OSPF and DC-ISIS routing stacks. "Metaswitch's OTN control plane technology is available today to our MPLS and IP routing customers as a straightforward, in-service software upgrade," said Jonathan Hardwick, Director of Product Management for Metaswitch's Network Protocols Division. "This enables our customers to introduce an industry standard OTN control plane solution in the fastest time possible." 

For new Metaswitch customers the OTN control plane solutions are available pre-integrated with all the leading operating systems, which also reduces time to market. For further details please see G.709 OTN or contact Metaswitch at
