ADDRESSING METHOD, ADDRESSING APPARATUS, FABRIC MANAGER, SWITCH, AND DATA ROUTING METHOD
First Claim
1. An addressing apparatus, comprising:
- 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 plurality of trees created by the tree creating unit; and
an address assigning unit for assigning addresses to each of switches and each of hosts in a network with respect to each tree having a minimum height selected by the tree selecting unit.

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.
