Revisiting Access and Aggregation Network Architecture
2014
Journal of Advances in Computer Networks
Optical technologies allow the end-user to take advantage of a very high bitrate access. This in turn modifies traffic patterns to be supported by access and aggregation (metro) networks. The present paper first proposes tentative traffic scenarios to assess future capacity requirements for these networks. It is shown that the current aggregation architecture based on primary and secondary aggregation rings should be reconsidered to limit potential bottlenecks and to take account of both
