“…Figure 10 depicts the normalized throughput of five types of six-stage SeLMINs when multicast ratio is w = 0.5 versus offered load on inputs. The five types of study cases of six-stage single buffered SeLMINs are denoted by the following sets of factors (G S , G F , G L ): (1,2,32), (2,2,16), (3,2,8), (4,2,4) and (5,2,2), respectively. The dot-dashed curve AM-Gs=a% depicts results which are obtained by the analytical method, whereas the solid curve SM-Gs=a% shows results that are obtained by simulation.…”

SUMMARYHere a novel analytical method for performance prediction estimation of single-and multi-layer multistage interconnection networks (MINs) under multicast environments is presented. The 'Cell Replication While Routing' is used as a packet routing technique and the 'full multicast' mode as transmission policy is employed in all the MINs under study. This model is developed for single-layer MINs and is extended and applied to special types of multi-layer MINs, called semi-layer MINs, which support mixed traffic patterns such as unicast and multicast in uniform traffic conditions. The results confirm the significant performance saturation of single-layer MINs and the improvement of corresponding performance indicators by semilayer MINs. The proposed analytical framework is anticipated to be a very useful tool in evaluating the performance of semi-layer MINs in designing more efficient QoS networks.

“…Contrary to other approaches [35,36], where priority is defined at the application layer (e.g. real-time packets from streaming media vs. non-real-time packets from file transfer; out-of-band data vs. ordinary TCP traffic and so forth) or in the parallel systems architecture level (e.g.…”

In this paper, the modelling, analysis and performance evaluation of a novel architecture for internal-priority finite-buffered multistage interconnection networks (MINs) are presented. We model the proposed architecture giving the details of its operation and describing its states and detailing conditions and effects of state transition; we also provide a formal model for evaluating its performance. The proposed architecture's performance is subsequently analysed under the uniform traffic condition, considering various offered loads, buffer lengths and MIN sizes, using simulations. We compare the internal-priority scheme vs. the non-priority (or single priority) scheme, by gathering metrics for the two most important network performance factors, namely, packet throughput and the mean time a packet needs to traverse the network. We demonstrate and quantify the improvements on MIN performance stemming from the introduction of priorities in terms of throughput and a combined performance indicator which depicts the overall performance of the MIN. These performance measures can be valuable assets for designers of parallel multiprocessor systems and networks in order to minimise the overall deployment costs and delivering efficient systems.

“…The same topic is also analyzed by Nasser et al [13] using different approaches. Moreover, Vasiliadis et al [14,15] studied MIN performance evaluation in terms of priority, on finite-buffered MINs with symmetric and asymmetric-sized buffer queues respectively, applying a simulation technique. Also, the findings by Garofalakis et al [6] are typical of what is found when applying analytical techniques to singlelayer multistage networks.…”

SUMMARYMultilayer multistage interconnection networks (MLMINs) integrate communication with network components and the components of parallel systems, especially when they service multicast traffic. This paper presents an approximate performance methodology for self-routing MLMINs that consist of two segments, each of which is composed of symmetrical switch elements. The first segment is subject to blocking situations with one mode of packet transmission policy (unicast). The second segment-the multilayer-is blocking free and employs double modes of transmission policy (unicast and multicast replication). Applying the current analytical model, which is based on a convergence method on the above types of MLMINs, an estimate can be made of their performance indicators. This model was applied to variable network size MLMINs under different multicasting patterns of traffic. It was also validated by extensive simulations. All the MLMINs under study apply special packet (traffic) management techniques, which allow for the integration of sub-networking into larger networks such as grids. The results are accurate and useful for network engineering, especially in the service of local area networks.
