AMTP: Towards a high performance and configurable mulipeer transfer service

This paper presents the service specification and an excerpt of a performance analysis of the Adaptive Multicast Transfer Protocol (AMTP) focusing on different error handling strategies for multicast communication scenarios. The need for sophisticated and dedicated multicast mechanisms to be provided by transfer protocols (covering protocols of layers 3 and 4 according to the ISO/OSI Reference Model) in order to support group communication becomes evident in the light of the versatile QOS (Quality of Service) requirements imposed by multimedia applications and the broad service spectrum offered by different network architectures. Today’s protocols provide neither the required range of functionality nor the necessary performance.
