The switch fabric is self-routing and uses fixed-length minipackets within the switching fabric for all types of connections. Its architecture provides full input/output connectivity paths with FIFO (first-in-first-out) queueing at each output. The connection paths are non-overlapping, so there is no internal blocking. Because of output queueing, there is also practically no output port blocking. The uniformity in architecture allows the construction of any size fabric from a single basic module which could be realized on a single chip. Larger-size configurations can be realized either as single-stage configuration.<<ETX>>","PeriodicalId":436217,"journal":{"name":"IEEE INFOCOM '88,Seventh Annual Joint Conference of the IEEE Computer and Communcations Societies.

In the network, the information can be efficiently integrated and transported by making the most of the burstiness of the information flows and of the store-and-forward process at the transport nodes. First, a coding and multiplexing scheme for audio signals matched to the above transportation mode is proposed. The effectiveness of the scheme is demonstrated through computer simulation and the extent of the deviations are provided for some sets of parameters. The analysis provides useful tools to perform sensitivity analysis of network delay performance.<<ETX>>","PeriodicalId":436217,"journal":{"name":"IEEE INFOCOM '88,Seventh Annual Joint Conference of the IEEE Computer and Communcations Societies.

A station is able to enter a lower latency state whenever its message queue is empty. They present a detailed evaluation and comparison of network performance, based on both analytical and simulation results. The performance of a dual latency token ring is analyzed for the case of limited-to-one service, symmetric traffic, and is compared to the performance of a conventional token ring operating with limited-to-one, gated, or exhaustive service. The authors use discrete-event simulation to model the behavior and performance of a duel latency ring with asymmetric traffic, and compare with the above three service disciplines. Results show a significant reduction in mean waiting time for the dual latency ring, with performance approaching or exceeding that of gated and exhaustive service, for certain ranges of network utilization.<<ETX>>","PeriodicalId":436217,"journal":{"name":"IEEE INFOCOM '88,Seventh Annual Joint Conference of the IEEE Computer and Communcations Societies.

For this class of networks the nonblocking conditions are given. In particular, by the graph colouring technique, it has been proved that the minimum number of delta subnetworks (L) necessary to provide the nonblocking property is L=n where n is the size of the basic switching element and S the number of stages required by an N*N delta network. A routing algorithm for the establishment of any permutation has been defined. It operates for any value of n and shows a polynomial time complexity equal to O(N/sup 3///sup 2/). Moreover, in case of the setup of a single connection request, this algorithm assures a time complexity equal to O( square root N). This property makes it well suitable to an asynchronous telecommunication environment.<<ETX>>","PeriodicalId":436217,"journal":{"name":"IEEE INFOCOM '88,Seventh Annual Joint Conference of the IEEE Computer and Communcations Societies.

Access to each net (edge) is time-slotted, and the system maintains global slot synchronization. The integration of voice into the system is done by reserving time slots in a periodic manner. A packet which contains several voice parcels from different phone conversations is transferred in these slots. These parcels may have different destinations on the optical net. As a result of the global end-to-end synchronization, the delay from the source to the destination is a known constant, with accuracy of plus or minus half a time slot. In the analysis, it is shown that the system improves its operation as the communication bandwidth increases. In other words, the algorithms and protocols improve in performance as the communication bandwidth increases. Two criteria are used to exhibit this phenomenon: (i) the utilization efficiency and (ii) the end-to-end delay.<<ETX>>","PeriodicalId":436217,"journal":{"name":"IEEE INFOCOM '88,Seventh Annual Joint Conference of the IEEE Computer and Communcations Societies.
