The BERKOM-II FlowSpec and its mapping on ATM

The BERKOM multimedia transport service provides a communication platform for audiovisual communication. It incorporates a modified version of the Xpress Transfer Protocol (XTP-Lite) and the Internet Stream protocol Version II (ST-II). For the utilisation of ATM networks a variety of issues have to be resolved. One of them is the translation and mapping of the quality of service (QoS), that is offered at the transport layer service access point (SAP), to the QoS and network performance (NP) parameters that are offered at the physical SAP to the ATM layer. In this work a mapping of the BERKOM-II FlowSpec on ATM is given and equations for the translation of the respective parameter values are given. The control of the network layer connections is done using procedures and parameters that are currently defined in the ATM control plane.
