C-COR Introduces Industry's Highest GigE Port Density for Flow-Based IP Transport Networks.

STATE COLLEGE, Pa. -- 10-Port GigE Module Enables Cost-Effective Commercial Services with QoS over Carrier Ethernet Platform

C-COR Incorporated (Nasdaq: CCBL), a global provider of interoperable network solutions that simplify the transition to on demand networks, today announced the introduction of the XGSIM, a 10-Port GigE Service Interface Module for use in its Multi-Service Packet Switch (MPS) System. The new XGSIM module gives service providers a high-density, cost-effective solution for deploying business data services with dynamic, on demand bandwidths up to 1 Gbps.

C-COR's commercial services solution is a comprehensive approach that includes the MPS System as well as a full suite of C-COR's IP and Ethernet products from Customer Premise Equipment to scalable DWDM transport. The MPS System combines Carrier Ethernet switching with an efficient regional transport system into one integrated platform. The MPS System equips service providers with a flexible and scalable next-generation Carrier Ethernet solution that supports both 10 Gbps Ethernet and OC-192 SONET optical packet rings. Additionally, the MPS has an innovative per flow Quality of Service (QoS) traffic management architecture that optimizes bandwidth efficiency, while minimizing delay and jitter. This unique combination of switching, transport, and QoS capabilities makes the MPS a powerful IP solution for network applications such as commercial and residential data services.

In addition to providing 10 discrete 1 Gigabit Ethernet SFP (Small Form-Factor Pluggable) ports, the XGSIM module performs switching, VLAN tagging, rate shaping, and classification required for advanced per subscriber QoS guarantees and network control. In conjunction with the MPS, the XGSIM supports Variable Information Rate (reclaimable) and Guaranteed Information Rate traffic classes to enable the service provider to map traffic to individual data flow queues. This ensures that traffic associated with one service is unaffected by traffic associated with other services and prevents such issues as denial of service attacks and peer-to-peer bandwidth abuse. Likewise, the MPS with the XGSIM module allows the provider to offer a service having both committed and burst bandwidth components and thus to substantially share the metro core ring capacity for better ROI.

C-COR will have its first public showing of the XGSIM module at the SCTE Cable-Tec Expo (Booth #8094) in San Antonio, Texas, on June 14-17, 2005. The XGSIM module is expected to be available for field trials and initial orders by the fourth quarter of calendar year 2005.
