Abstract: The present disclosure provides an addressing method, an addressing apparatus, a fabric manager, a switch, and a data routing method for data center networks. The addressing apparatus includes a tree creating unit for, sequentially with each of switches as a root, creating a tree containing all hosts by means of network topology discovery function, to obtain a plurality of trees; a tree selecting unit for selecting a tree having a minimum height among the created plurality of trees; and an address assigning unit for assigning addresses to each of switches and each of hosts in a network with respect to each selected tree having a minimum height. The present disclosure is adaptable to various topologies employed by the data center. The present disclosure can achieve aggregation of locator addresses so that a forwarding table can be shortened, and can achieve load balance of the network.

Abstract: The invention provides a dynamic flow division scheduling system and a dynamic flow division scheduling method for a data center network. A host machine applies for bandwidth reservation of specific flow for a flow scheduler of a data center; the flow scheduler checks the bandwidth using conditions of all paths which can be selected by the specific flow; if the sum of bandwidths retained on the paths meets the demand for the bandwidth of the specific flow, the flow is divided into one or more sub-flows, and then the sub-flows are forwarded on the corresponding paths; and if the bandwidths retained on all the paths cannot meet the demand for the bandwidth of the specific flow, the current flows on the paths are transferred to other paths, so that a space is reserved for forwarding the specific flow. According to the dynamic flow division scheduling system and the dynamic flow division scheduling method, the actual bandwidth demand of the flow can be timely and accurately obtained, and scheduling can be performed on the granularity which is thinner than the flow, so that the utilization rate of the whole data center network is balanced, and the convergence bandwidth of the whole data center network is increased.

Abstract: The invention provides a server, a method and a system for providing node information for P2P network. A server in a peer-to-peer (P2P) network comprises: a location information storage unit which stores coordinate information indicating a coordinate of each data node in the P2P network in a coordinate system that is created based on communication delays among data nodes in the P2P network; and a node information providing unit which, upon receipt of a request for information on data nodes having a first data item, selects one or more data nodes from data nodes having the first data item based on the coordinate information, and provides information indicating the selected one or more data nodes.
