NETWORK NODE AND METHOD FOR DISTRIBUTING LOAD OF THE NETWORK

摘要

A network module includes: a plurality of network modules on which a virtual node is mounted; and a switch module serving as an origin of a star connection when star-connecting a plurality of network modules.  Each of the network modules has: a physical interface for connecting the network module to an external module; and a network virtualization unit which searches for a destination in accordance with a key extracted from information contained in data which has arrived at the physical interface so as to check whether the destination is a virtual node mounted on a network module having the physical interface which has arrived or a virtual node mounted on a network module connected via a switch module.  The network virtualization unit transfers the data to the virtual node mounted on either of the network modules in accordance with the check result.
