Overcoming the Challenges of keeping Packet Ring Networks – Resilient!

Today, network operators in all markets are facing a similar challenge - “how to carry all types of traffic (voice, video, data) on a single, efficient network infrastructure?” Without existing infrastructure to consider, there are many options. For those already operating networks, usually SONET-based, finding the best strategy is more complex.

Traditional SONET equipment has been enhanced with packet networking features creating today’s Next-Generation SONET ADM. But this functionality is bounded by the limitations of both SONET world and the packet world – unfortunate. Native packet functionality is ill-designed to function in the fiber-ring environment commonly found in metro environments, and lacks features required for a “carrier-grade” service.

One relatively new technology has been created to leverage the Qos and reliability of SONET networks, while maintaining the efficiency and dynamic qualities of a packet network – resilient packet ring (RPR). RPR is designed for a fiber-ring based environment, and provides SONET-like protection capabilities, as well as substantial QoS features.

LightRiver’s Chief Technology Officer, Dean Campbell, will be presenting a discussion of RPR technology, the enhanced features that it provides, and whether RPR is a technology that you can employ to offer packet (Ethernet) services with high QoS. Please join us Thursday, September 7th, 2006 at 1:30PM EST to explore another chapter in LightRiver’s continuing effort to provide valuable technology and market information to our clients.
