The PHLX decided to expand its network capabilities by augmenting its existing single data center with additional sites closer to traders in the metropolitan New York area. The new network design utilizes.http://whitepapers.techrepublic.com.com/abstract.aspx?docid=385644 A Scalable, Commodity Data Center Network Architecture- September 10, 2008 Today's data centers may contain tens of thousands of computers with significant aggregate bandwidth requirements. The network architecture typically consists of a tree of routing and switching elements with progressively more specialized and expensive equipment moving up the network hierarchy. Unfortunately, even when deploying the highest-end IP switchesrouters, resulting topologies may only support 50% of the aggregate bandwidth available at the edge of the network, while still incurring...http://whitepapers.techrepublic.com.com/abstract.aspx?docid=385432 A New Algorithm for Crossbar Switch Problem Using Hopfield Neural Network With Continuous Hysteresis Neurons- September 10, 2008 This paper proposes a continuous hysteresis neurons Hopfield neural network architecture for efficiently solving crossbar switch problems. A Hopfield neural network architecture with continuous hysteresis and its collective computational properties are studied. It is proved theoretically and confirmed by simulating the randomly generated Hopfield neural network with continuous hysteresis neurons. The network architecture is applied to a crossbar switch problem and results of computer...http://whitepapers.techrepublic.com.com/abstract.aspx?docid=385430 Layered Control to Enable Large Scale SOA Switch Fabric- September 10, 2008 Increasingly sophisticated photonic integrated circuits with high numbers of active components such as multi-stage switch fabrics introduce complex control challenges. Studies on Semiconductor Optical Amplifier (SOA) based switch fabrics have shown low penalty operation for high levels of cascading for wavelength multiplexed packets. However, as the number of wavelengths, and therefore data capacity increases, the optimum operating regimes become more restrictive and fine tuning of the...http://whitepapers.techrepublic.com.com/abstract.aspx?docid=385408 IM-OM Matching Packet Dispatching Scheme for MSM Clos-Network Switches- September 10, 2008 Current packet dispatching algorithms for next generation network nodes (switchesrouters), in the majority of cases, involve the request-grant-accept handshaking scheme with many iterations and the effect of desynchronization of arbitration pointers. For high-performance switches and routers the Clos switching fabric is very attractive because of its modular architecture and scalability. It is almost impossible to implement the algorithms with multiple phase iterations in the three-stage...http://whitepapers.techrepublic.com.com/abstract.aspx?docid=385394 |
