20120243403 | ADDRESSING METHOD, ADDRESSING APPARATUS, FABRIC MANAGER, SWITCH, AND DATA ROUTING METHOD - 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. | 09-27-2012 |
20110161261 | METHOD AND SYSTEM FOR TRAFFIC PREDICTION BASED ON SPACE-TIME RELATION - A system and method for traffic prediction based on space-time relation are disclosed. The system comprises a section spatial influence determining section for determining, for each of a plurality of sections to be predicted, spatial influences on the section by its neighboring sections; a traffic prediction model establishment section for establishing, for each of the plurality of sections to be predicted, a traffic prediction model by using the determined spatial influences and historical traffic data of the plurality of sections; and a traffic prediction section for predicting traffic of each of the plurality of sections to be predicted for a future time period by using real-time traffic data and the traffic prediction model. An apparatus and method for determining spatial influences among sections, as well as an apparatus and method for traffic prediction, are also disclosed. With the present invention, a spatial influence of a section can be used as a spatial operator and a time sequence model can be incorporated, such that the influences on a current section by its neighboring section for a plurality of spatial orders can be taken into account. In this way, the traffic condition in a spatial scope can be measured more practically, so as to improve accuracy of prediction. | 06-30-2011 |
20090033466 | Tag Identification System, Tag Reading Apparatus, and Method for Determining Location of Tags - The invention provides a tag identification system, a tag reading apparatus, and a method for determining location of tags. According to an aspect of the invention, a tag identification system comprises a tag reading apparatus which transmits interrogation signals and a plurality of tags arranged in a sequence, wherein each of the plurality of tags is capable of returning a reply in response to a received interrogation signal; the tag reading apparatus at least comprises a location determination unit which determines the arrangement location of the plurality of tags based on replies received by the tag reading apparatus which are returned by the plurality of tags in response to interrogation signals. | 02-05-2009 |
