摘要
A distributed storage system includes: a plurality of servers that store data that is associated with key information, respectively; a packet forwarding apparatus that, on receipt of a new packet that contains the key information and is addressed to one of the plurality of servers, requests a control apparatus to decide a forwarding destination from among the plurality of servers; and the control apparatus. The control apparatus includes: a forwarding destination selection section that decides a forwarding destination of the packet based on key information in a header part of the packet; and an entry setting section that sets, in a packet forwarding apparatus(es) on a path to the forwarding destination, a flow entry for forwarding a subsequent packet(s) with same key information to the forwarding destination. The packet forwarding apparatus(es) forwards a packet(s) with the same key information to the forwarding destination using the set flow entry.
