“…In this paper, we will focus on operating system and architectural issues, as we feel that high-performance protocol architecture features such as ordering, errors, duplicates, coordination, and format conversion have been well-covered by others; see for example Feldmeier [16].…”

Network fabrics with Gigabit per second (Gbps) bandwidths are available today, but these bandwidths are not yet available to applications. The difficulties lie in the hardware and software architecture through which application data travels between the network and host memory. The hardware portion of the architecture is often called a host interface and the remainder of the protocol stack is implemented in host software.In this paper, we outline a variety of approaches to the architecture of such systems, examine several design points, and study one example in detail. The detailed example, an ATM Host Interface and Operating System support built at the University of Pennsylvania, illustrates design tradeoffs for hardware and software, and some of the implications of these tradeoffs on applications performance.

“…In this case, the incoming network packets are demultiplexed only once by the ATM device driver on a per VC basis. Since no multiplexing and demultiplexing overheads are incurred (except at device driver layer) at higher layers, application jitter is therefore reduced [25,26]. This results in much better video performance of two video streams as illustrated in Fig.…”

“…Demultiplexing the communication architecture [Feldmeier93] underlines that demultiplexing at the lowest possible level enables each data flow to be isolated, and makes per-flow processing possible (e.g. for QoS, or Quality of Service, support).…”

This paper analyzes the efficiency of various high performance implementation techniques for the communication system of UNIX workstations. Using an Open System implies that a certain compatibility level is required from the protocol, user interface, and implementation framework. These constraints limit the opportunities to design a high performance communication system. We have designed an experimental platform around the TCP/IP protocol suite, using the STREAMS environment. A BSD TCP/IP stack and a classic STREAMS based TCP/IP stack serve as reference implementations for performance comparisons. We explain why the efficiency of some high performance implementation techniques we applied to this platform is limited. The impacts of the hardware architecture, of the operating system, and of the communication stack architecture on performances are analyzed. It is shown that the efficiency of data transmission would benefit from more simplicity and more synchronism in the communication environment, from direct data paths between the applications and the device drivers, and from a limited ILP integration.
