Balancing Security and Performance in Videoconferencing Deployments

Time 04/22/08 04:30PM-05:30PM

Session Abstract

It is common today to have H.323 and SIP videoconferencing equipment deployed behind firewalls/NATs in campus and enterprise networks. Although a variety of network security-policy reasons drive these deployments, network planners continually face challenges that involve balancing network security for data traffic and end-user Quality of Experience (QoE) for voice and video traffic. Improper decisions could result in vulnerable networks, slow data transfers as well as video frames freezing and audio dropouts. Recently, several new standards and vendor solutions have emerged that aim at solving the challenges for secure videoconferencing deployments.

The purpose of this talk is to familiarize the audience regarding these recent developments, and discuss the limitations and caveats that exist in their adoption. The first-half of this talk will focus on state-of-the-art solutions, and corresponding signaling-and-media flow architectures involved in deploying secure videoconferencing systems. The solutions include the Polycom V2IU, GNU Gatekeeper Proxy, and the Cisco PIX with H.323 fixup. The second-half of this talk will discuss the interoperability, load and vulnerability testing of these solutions conducted at the Ohio Supercomputer Center. The talk will conclude with a discussion on the best-practices for deploying small-to-large scale secure videoconferencing deployments in campus and enterprise networks.
