Example text

1 Hardware support for remote I/O The implementation of the InfoPad portable hardware (Figure 2— 3) centers around the model of parallel I/O processing modules connected to a backbone network via a single-hop wireless link. With the long-term vision that the backbone network would exist within a virtual circuit-switched framework, our design philosophy was that the InfoPad should be an extension of the backbone network. Thus, the main function of the hardware is to support data flow between multimedia sources (or sinks) and the wireless link.

At the transport layer, an end-to-end, connection-oriented protocol such as TCP is not well-suited to the transmission of real-time, isochronous data across a wireless link. Re-transmitting a lost image frame from a streaming movie, or attempting to retransmit a lost audio frame would in many cases violate the delay constraints for these data types. Further, no well-known transport protocol is particularly suited to the burst error characteristics of the wireless channel. (With TCP in particular, the congestion-avoidance mechanism enhance negative effects of retransmission, since a burst of errors interpreted as severe congestion in the channel, forcing the sender to further restrict the rate of transmission [BPSK96]).

Since in wired networks the point-to-point network topology is essentially static, physical-layer channels can be modeled as time-invariant systems and user-to-user interference can be modeled as a stationary random process. Both of these properties provide simple, understandable statistical models for characterizing the probability of errors, justifying abstractions that allow the services provided to be partitioned into orthogonal concerns. For example, a networked file system provides the abstraction that all files reside on a single logical file system, greatly simplifying the design of an application that read and write files using a standard file I/O interface.
