C-COR'S IP Expert to Address Vital Role of Performance Metrics in Managing VoIP Service Quality At SCTE Symposium.

STATE COLLEGE, Pa. -- C-COR Incorporated (Nasdaq:CCBL) announced today that Rich Higgins, the Company's Chief Corporate Technologist for IP Applications, will present "The Role of Performance Metrics in Managing VoIP Service and Call Quality" at the SCTE (Society of Cable and Telecommunications Engineers) VoIP Advanced Development Symposium in Denver, Colorado. Mr. Higgins is scheduled to speak at the Symposium's technical session on Network Performance Metrics on May 5, 2005, at 1:30 PM MT. His paper, which is co-authored by Dan Rice, Vice President of Advanced Technology for C-COR Solutions, identifies the metrics and methods used to analyze and manage VoIP service performance across different segments of the network.

The performance and reliability of cable networks are critical to the roll-out of IP-based telephony services, particularly given that voice is being delivered over networks already offering high-speed data and video services. No other service has such stringent technical requirements and high subscriber expectations for quality and reliability than voice. From a monitoring perspective, however, voice is particularly difficult because there are so many systems involved and quality must be assessed in both directions. Moreover, the cable operator may or may not own and operate many of these systems. Each system and network segment presents its own unique set of monitoring challenges and failure modes. In this complex environment, cable operators are turning to network performance metrics to manage against high VoIP subscriber expectations and set benchmarks to ensure the quality of service. In his presentation, Mr. Higgins will address the different techniques and metrics for call quality, which variables are most important, and which can be effectively controlled.
