This paper focuses on designing high performance pipelined networks that can operate in the presence of dynamic component failures. A general, rigorous framework for deadlock-free communication in faulty, pipelined networks is developed. L\ mechanism is also proposed for recovering from dynamic link and node failures. The recovery mechanism 1) is fully(More)
Fault-tolerant routing protocols in modern interconnection networks rely heavily on the network flow control mechanisms used. Optimistic flow control mechanisms such as wormhole switching (WS) realize very good performance, but are prone to deadlock in the presence of faults. Conservative flow control mechanisms such as pipelined circuit switching (PCS)(More)
This paper presents a software based approach to fault-tolerant routing in oblivious, wormhole routed networks. When a message encounters a faulty output link it is removed from the network by the local router and delivered to the messaging layer of the local node’s operating system. The message passing software can re-route this message along a non-minimal(More)

This paper describes the undergraduate computer architecture courses and laboratories introduced at Georgia Tech during the past two years. A core sequence of six required courses for computer engineering students has been developed. In this paper, emphasis is placed upon the new core laboratories which utilize commercial CAD tools, FPGAs, hardware(More)
In communication network, the number of nodes is continuously passing messages to each other in a particular fashion. Every node knows its neighboring peer. So, it is necessary to learn the topology of the entire network. Usually, in this type of network many resources are shared and deal with faulty components. Therefore, Fault tolerance is measure issue(More)
This paper presents a software based approach to fault-tolerant routing in networks using wormhole or virtual cut-through switching. When a message encounters a faulty output link, it is removed from the network by the local router and delivered to the messaging layer of the local node’s operating system. The message passing software can re-route this(More)
