Token transfer in a faulty network

Safe Register Token Transfer in a Ring

A token ring is an arrangement of n processors that take turns engaging in an activity which must be controlled. A token confers the right to engage in the controlled activity. Processors communicate with neighbors in the ring to obtain and release a token. The communication mechanism investigated in this paper is the safe register abstraction, which may arbitrarily corrupt a value that a proce...

The Priority Token Bank in a Network of Queues

This paper takes a known approach for scheduling and admission control in integrated services networks, the Priority Token Bank (PTB), whose mechanism and performance have been studied in a single queue, and extends the algorithm to address the challenges of implementing it in a network of queues. An integrated services network must handle traffic streams with disparate arrival processes and pe...

Quantum network exploration with a faulty sense of direction

We develop a model which can be used to analyse the scenario of exploring quantum network with a distracted sense of direction. Using this model we analyse the behaviour of quantum mobile agents operating with non-adaptive and adaptive strategies which can be employed in this scenario. We introduce the notion of node visiting suitable for analysing quantum superpositions of states by distinguis...

Network Traac Characterization Using Token Bucket Model

| This paper investigated the problem of deriving token bucket parameters from the observed traac patterns of computer network ows in two cases. In the basic case, we identiied the set of token bucket parameters for any given ow so that all the packets in the ow will be delivered immediately without incurring any delay or loss. Then, we extended the basic case by adding a queue to the token buc...
