In this work we describe a series of performance tests on different architectures of high bandwidth local area networks, contemporarily in use at C.I.L.E.A. (Inter-University Consortium for Automatic Elaboration of Lombardy) to connect multi-processor machines devoted to educational and research purposes, such as fluido-dynamic and mechanical simulations. This LAN is essentially made out of a standard FDDI ring, and an HyperFabric backbone. HyperFabric is a Hewlett-Packard high performance network system bus, with a declared maximum bandwidth of 2.5 Gbit/s full duplex per link. We present a comparison, in terms of effective bandwidth, average throughput and CPU consumption of the above mentioned network systems. Furthermore we also describe the effects, in terms of transfer efficiency, of such a mixed environment, in which different systems co-exist and must often be cross-walked by various applications, as backups and mass storage access. Measurements and comparisons are made using Open Software tools like netperf and HetPIPE.

Mimo Transmission

In current local area networks, multimode fibers (MMFs), mainly graded index (GI) MMFs, are the main types of fibers used for data communications. Because of their high bandwidth, they are considered the main method of transmission that allows to offer multiservice broadband services using optical multiplexing techniques. The MGDM (ModeGroup Division Multiplexing) is a Multiplexing technique, which aims to improve the performance of the multimode optical fiber by spatially multiplexing the data streams to be transmitted. In this work, we study optical MIMO (multi-input multi-output) transmission systems on an MMF optical fiber, specifically the adaptation of the architecture of MIMO transmission systems. In this context, we have studied the mode group multiplexing technique (MDGM), to evaluate the transmission capacity. In fact, the latter depends on the injection conditions and the state of the optical fiber.
