Abstract

Multimedia workstation architectures differ from current architecture in these respects – they have multiple specialized processing units, a high speed I/O interconnect mechanism, a high speed broadband network interface and a real-tie multitasking operating systems (OS) that provides QoS guarantees. These systems will primarily be used to run distributed applications that require high network throughput and predictable delay and delay jitter for real-time traffic. We argue the need for a different protocol organization and processing architecture in order to achieve this. We show how the emerging hardware architecture and OS structures favor a “decentralized protocol processing” approach, that takes advantage of the data delivery mechanism provided by the hardware to improve in-band (protocol data) processing, and the sophisticated OS mechanisms based on communicating objects to improve the out-of-band (control) processing. We discuss the need for providing end-to-end QoS guarantees for applications and discuss how it can be naturally incorporated in the proposed architecture.
