Paper Abstract

For an expeditious and successful penetration of broadband services to residential and other small traffic subscribers, cost-efficiency by means of investment sharing and partial re-use of existing infrastructure are imperative. Employment of passive optical technology to feed subscriber clusters while maintaining the copper in the last drop is a promising strategy. To achieve traffic concentration and high utilization, a MAC protocol designed for low CDV is essential. A TDMA protocol based on ATM cells suitable for upgrading both twisted pair and coaxial based access networks creating hybrid solutions is presented. This protocol offers a dynamic response at cell level to the bursty traffic expected in B-ISDN using the reservation method to sample by periodic requests the arrival rate. No resort to signalling related information is required. Differentiating the handling between delay tolerant and non-tolerant traffic can offer significantly higher exploitation and a cost effective solution for the local loop.
