Abstract
In a network including a plurality of switches, different priority levels are assigned to different services based on a frequently requested service list provided from an end system including an end host and a server, and a forwarding rule containing path information for forwarding data packets is selectively set according to the priority levels. A first forwarding rule set for a service of the first priority level is loaded to corresponding ones of the plurality of switches.
Claims16
A method for setting a forwarding rule in a network comprising a plurality of switches, the method comprising:
- receiving a frequently requested service list from an end system comprising an end host and a server;
- assigning different priority levels to different services based on the frequently requested service list, and selectively setting a forwarding rule containing path information for forwarding data packets according to the priority levels;
- preliminarily loading a first forwarding rule for a service of the first priority level to corresponding ones of the plurality of switches;
- and
- storing and managing forwarding rules set for services other than the service of the first priority level, without preliminarily loading the same to the corresponding switches.
A control apparatus for setting and controlling a forwarding rule in a network comprising a plurality of switches, the apparatus comprising:
- a scalable forwarding rule manager that assigns different priority levels to different services based on a frequently requested service list provided from an end system comphsing an end host and a server, and selectively sets a forwarding rule containing path information for forwarding data packets according to the priority levels;
- a path manager that preliminarily loads a first forwarding rule set for a service of a first priority level to corresponding ones of the plurality of switches;
- a first table that stores information about the first forwarding rule set for the service of the first priority level;
- and
- a second table that stores information about a second forwarding rule set for a service of a second priority level,
- wherein the second forwarding rule for the service of the second priority level is stored and managed without being preliminarily loaded to corresponding switches.
