NETWORK SYSTEM, CONTROLLER, AND LOAD DISTRIBUTION METHOD |
摘要 |
A network system has a switch which transfers a packet and a controller which sets a flow entry to the switch. The controller has a heavy load switch detecting section which detects a heavy load switch with the heavy load of new flow entry setting processing; a storage section which stores a switch list; an alternate route searching section which searches an alternate route; and a flow entry setting section which assigns a flow of packets to be transferred by using a new flow entry of the heavy load switch to the switch on the alternate route, without changing the flow entry which is already set to the heavy load switch. |

1. A network system comprising:
a switch configured to transfer a packet; and a controller configured to set a flow entry for the packet to said switch, wherein said controller comprises: a heavy load switch detecting section configured to detect said switch as a heavy load switch when said switch is in a heavy load state of new flow entry setting processing; a storage section configured to store a switch list; an alternate route searching section configured to search an alternate route which does not use said heavy load switch, from the switch list; and a flow entry setting section configured to set a new flow entry for a new packet to a new switch on the alternate route searched by said alternate route searching section without setting the new flow entry to said heavy load switch. |
