NETWORK NODE AND LOAD DISTRIBUTION METHOD FOR NETWORK NODE

摘要

A network node includes: a plurality of network modules in which virtual nodes are installed; and a switch module being a starting point of a star connection when the network modules are connected in the star connection. Each network module includes: a physical interface connecting the network module to an outside network; and a network virtualization unit carrying out, with respect to data arriving in the physical interface, a destination search based on keys extracted from information of the data to determine whether the destination is a virtual node installed in a network module that includes the physical interface at which the data arrived or a virtual node installed in a network module that is connected by way of the switch module, and transmitting the data to a virtual node mounted in either network module in accordance with the determination result.
