CONTROL APPARATUS, COMMUNICATION SYSTEM, NODE CONTROL METHOD AND PROGRAM |
摘要 |
The present invention prevents occurrence of phenomena such as non-arrival of packets when non-compatible apparatuses are connected to a centralized-control-type network. In a network comprising: a first node(s) controlled by a control apparatus in a centralized manner; a second node(s) storing, for a predetermined period, entries in each of which, based on a source address of a received packet, its own port and information about a node address(es) to which packets can be forwarded from the port are associated with each other and performing packet forwarding by referring to a group of entries and determining a port corresponding to a packet destination; and the control apparatus, the control apparatus causes the first node(s) connected to the second node(s) to transmit a destination learning packet to the second node(s) to cause the second node(s) to learn information about an address(es) to which packets can be forwarded from a port(s) of the second node(s) at predetermined time intervals. |
