SPIDER: Flexible and Efficient Communication Support for Point-to-Point Distributed Systems
نویسندگان
چکیده
SPIDER is a network adapter that provides scalable communication support for point-to-point distributed systems. The device exports an eecient interface to the host processor, provides transparent support for dependable , time-constrained communication, and handles packet routing and switching. The communication support provided by SPIDER exploits concurrency between the independent data channels feeding the point-to-point network, and ooers exible and transparent hardware mechanisms. SPIDER allows the host to exercise ne-grain control over its operation, enabling the latter to monitor and innuence data transmission and reception eeciently. In the current implementation , SPIDER interfaces to the Ironics IV-3207, a VMEbus-based 68040 card and will be controlled by x-kernel, a communication executive allowing the exible composition of communication protocols.

Hardware Support for Controlled Interaction of Guaranteed and Best-eeort Communication
Real-time communication typically consists of guaranteed packets that must satisfy their delivery deadlines and best-eeort packets that can tolerate occasional deadline misses for improved average latency. This paper presents hardware techniques for supporting the coexistence of these two traac classes in real-time point-to-point networks. A careful selection of routing and switching techniques...
متن کاملArchitectural Support for Managing Communication in Point-to-Point Distributed Systems
Point-to-point networks provide a natural platform for distributed systems due to their high bandwidth, scalability, and the potential for exploiting communication locality. Managing these networks, however, is complicated by the disparate quality-of-service requirements of distributed applications. Since the various routing and switching schemes are best-suited for diierent classes of traac, t...

متن کاملQFT Control of a Two-Link Rigid-Flexible Manipulator
This paper evaluates a new and simple controller design method based on QFT (quantitative feedback theory) for a two-link manipulator whose first link is rigid and the second is flexible. A piezoelectric patch is attached to the surface of the flexible link for vibration suppression of it. This system is modeled as a nonlinear multi-input multi-output (MIMO) control systems whose inputs are two...
