    摘要： According to an example, a method for bandwidth guarantee and work conservation includes determining virtual machine (VM) bandwidth guarantees assigned to VMs in a network including a source VM that communicates with destination VMs. The method further includes assigning minimum bandwidth guarantees to communications between the source VM with the destination VMs by dividing a VM bandwidth guarantee assigned to the source VM between the destination VMs based on active VM-to-VM communications between the source VM and the destination VMs. The method also includes allocating, by a processor, spare bandwidth capacity in the network to a communication between the source VM and a destination VM based on the assigned minimum bandwidth guarantees.

    摘要： According to an example, a method for virtual machine (VM) data packet encapsulation and decapsulation may include receiving a data packet including a media access control (MAC) header and an internet protocol (IP) header. The method may further include encapsulating, by a processor, the received data packet to include an encapsulating MAC header, an encapsulating IP header, a VM MAC header with a same content as the MAC header of the received data packet, and a VM IP header with a same content as the IP header of the received data packet.

    摘要： Forwarding a flow in a network includes receiving the flow at a switch, determining an optimized priority queue level of the flow at the switch, and forwarding the flow via the switch using an optimized priority queue level of the flow at the switch. The flow passes through a plurality of switches, including the switch, in the network, and the optimized priority queue level of the flow at the switch is different from a priority queue level of the flow at a second switch of the plurality of switches. The second switch routes the flow at the second switch using the different priority queue level for the flow.

    摘要： Local rules for managing flows devolved from a central controller are received at a switch. The central controller determines a global set of rules for managing flows. The switch receives a packet from a flow from a network and determines whether a metric for the flow satisfies a dynamic condition to trigger a metric report to the central controller. In response to a determination that the metric for the flow at the switch satisfies the dynamic condition to trigger a metric report to the central controller, the switch sends a metric report to the central controller, and the switch then receives an instruction to manage the flow from the central controller. In response to a determination that the metric for the flow at the switch does not satisfy the dynamic condition to trigger the metric report to the central controller, the switch manages the flow using the local rules for managing flows.

    摘要： Distances are determined between an identified node and landmark nodes and milestone nodes in a network. The closest milestone or landmark node associated with a shortest of the measured distances is determined. A corresponding distributed hash table (DHT) overlay node is queried for distances between observed nearest nodes for the closest milestone or landmark node and the identified node. Distances between the identified node and the observed nearest nodes are calculated from distances received from the DHT overlay node and the measured distance to the closest milestone or landmark node. K-closest nodes from the identified node are selected from at least one of the closest milestone or landmark node and one or more of the observed nearest nodes based on the calculated distances.
