The case for RPR

The Resilient Packet Ring Alliance has prepared a business case study comparing RPR as an alternative method for adding data services to SONET/SDH networks.

The Resilient Packet Ring Alliance, an industry advocacy group promoting resilient packet ring (RPR) technology and its standardisation by the IEEE, hasprepared a business case study comparing RPR as an alternative method for adding data services to SONET/SDH networks.

The study, available in a PDF format by clicking <a href=’http://www.rpralliance.com/articles/business_case_latest.pdf’>here</a>, analyses CapEx and OpEx of a SONET/SDH network with RPR technology, from an initial deployment scenario to those that increase users and bandwidth per users as well as scenarios based on next-generation SONET deployments.

The study finds that carriers can achieve significant CapEx and OpEx savings as networks scale both in terms of number of users on the network and increased bandwidth per user.

‘Carriers today face many challenges in terms of rolling out tomorrow’s metro services-video, voice, and data-while controlling CapEx and OpEx,’ said John Hawkins, chair of the RPR Alliance and senior marketing manager for Nortel Networks.

‘This business case shows how RPR can be deployed over an existing SONET/SDH network as it evolves to address multi-service requirements. But this is only the tip of the iceberg, and we look forward to publishing additional business case analyses that explore a variety of service rollout scenarios in addition to this one.’
