Abstract

This paper describes the Flow to VC mapping control module that is embedded in the RSVP over ATM implementation of the ACTS project DIANA. As part of an edge router at the ingress to the ATM network, this module provides signalling translation from RSVP to ATM, handles the admission of flows to ATM VCs and controls an IP over ATM queueing discipline. It is thus an example of a traffic descriptor and QoS parameter based resource reservation that strictly guarantees end-to-end QoS. In order to address scalability issues, a concept of massive aggregation of flows to VCs and a dynamic bandwidth management is applied to reduce the control overhead induced by signalling and the maintenance of per-flow state information. The resulting architecture is compared with the IP based Scalable Reservation Protocol SRP and the Differentiated Services implementation SIMA.
