Connecting QoS: The Key to Quality End-to-End Networking

Customers today expect a high level of network performance and reliability, regardless of whether their services are offered by one or several communications services providers.Yet the industry just now is defining quality of service relative to intercarrier connections, said David Malfara Sr., president and CEO of Remi Communications.

During todays Carrier Track session, Malfara and Mitch Ferro, senior director of product management IP & enhanced services at Broadwing Communications, along with moderator Dick Tomlinson, executive vice president of New Paradigm Resources Group, will talk about intercarrier QoS as well as other quality and security issues, in the panel Ensuring QoS and Security in a Converged World.

If a customer in Pennsylvania has a terminating point in California, today there is no way to QoS on that connection, said Malfara of Remi, a carrier providing advanced services to medium- and large-scale enterprise customers. But the industry is defining QoS parameters at Layer 2 so companies like Remi can provide end-to-end service guarantees. That usually involves employing Layer 2 MPLS, which is VPLS service, and hierarchical VPLS, or HVPLS. Malfara notes that the IETF, MEF and VPLS.org are among the industry organizations working on such QoS challenges.

Meanwhile, Remi is building a network from Layer 1 with WDM all the way to the IMS as the application layer, he said. We just deployed a MetaSwitch IMS platform and VoIP platform for enterprise, and Layer 2 and 3 technology from Riverstone [now Lucent Technologies Inc.] through their 15800 product.

And once intercarrier QoS is in place, that also sets the stage for the introduction of more real-time protocol-based services like VoIP and video, he added.
