    摘要： A method, system and computer program product are disclosed for routing data packet in a computing system comprising a multidimensional torus compute node network including a multitude of compute nodes, and an I/O node network including a plurality of I/O nodes. In one embodiment, the method comprises assigning to each of the data packets a destination address identifying one of the compute nodes; providing each of the data packets with a toio value; routing the data packets through the compute node network to the destination addresses of the data packets; and when each of the data packets reaches the destination address assigned to said each data packet, routing said each data packet to one of the I/O nodes if the toio value of said each data packet is a specified value. In one embodiment, each of the data packets is also provided with an ioreturn value used to route the data packets through the compute node network.

    摘要： A network system includes a plurality of sub-network planes and global switches. The sub-network planes have a same network topology as each other. Each of the sub-network planes includes edge switches. Each of the edge switches has N ports. Each of the global switches is configured to connect a group of edge switches at a same location in the sub-network planes. In each of the sub-network planes, some of the N ports of each of the edge switches are connected to end nodes, and others of the N ports are connected to other edge switches in the same sub-network plane, other of the N ports are connected to at least one of the global switches.

    摘要： A method and apparatus for selectively parking routers used for routing traffic in mesh interconnects. Various router parking (RP) algorithms are disclosed, including an aggressive RP algorithm where a minimum number of routers are kept active to ensure adequate network connectivity between active nodes and/or intercommunicating nodes, leading to a maximum reduction in static power consumption, and a conservative RP algorithm that favors network latency considerations over static power consumption while also reducing power. An adaptive RP algorithm is also disclosed that implements aspects of the aggressive and conservative RP algorithms to balance power consumption and latency considerations in response to ongoing node utilization and associated traffic. The techniques may be implemented in internal network structures, such as for single chip computers, as well as external network structures, such as computing clusters and massively parallel computer architectures. Performance modeling has demonstrated substantial power reduction may be obtained using the router parking techniques while maintaining Quality of Service performance objectives.

    摘要： A computer device may include logic configured to generate a virtualized environment for a customer; receive a request to provide a route reflector service for the customer; and generate a virtual route reflector on the generated virtualized environment, in response to receiving the request to provide the route reflector service for the customer. The logic may further be configured to establish a Virtual Private Network (VPN) or secure tunnel connection between the generated virtual route reflector and a client router associated with a customer network via a cloud center access system, wherein the cloud center access system connects a cloud center system that includes the computer device to a provider network that includes the client router; and establish a Border Gateway Protocol (BGP) session between the client router and the generated virtual route reflector using the established VPN or secure tunnel connection.

    摘要： Associations are maintained among a plurality of subnets, policies, and client types. Each subnet has an associated client type and policy. For a particular client device, (i) a client type of the particular client device, and (ii) a client type associated with the subnet on which the particular client device is hosted is determined. For the particular client device, (i) the determined client type of the particular client device with (ii) the determined client type associated with the subnet on which the particular client device is hosted is compared. Responsive to a determination that the client type of the particular client device matches the client type associated with the subnet that hosts the particular client device, a policy is applied to the particular client device.

    摘要： Systems and methods described herein are directed to solutions for Network on Chip (NoC) interconnects that automatically and dynamically determines the position of hosts of various size and shape in a NoC topology based on the connectivity, bandwidth and latency requirements of the system traffic flows and certain performance optimization metrics such as system interconnect latency and interconnect cost. The example embodiments selects hosts for relocation consideration and determines a new possible position for them in the NoC based on the system traffic specification, shape and size of the hosts and by using probabilistic function to decide if the relocation is carried out or not. The procedure is repeated over new sets of hosts until certain optimization targets are satisfied or repetition count is exceeded.
