Abstract
A switch system realizes extension of the number of entries of an open flow table by using tables in a switch as existing resources. Specifically, the switch configures an open flow table by logically combining a plurality of tables, each of which defines processing to a given packet, based on a condition and a processing content defined in each table. The switch refers to the open flow table to determine the processing content to a reception packet. The switch executes the processing of the reception packet based on the determined processing content.
Claims9
A switch system comprising:
- an open flow functioning section which configures an open flow table by logically combining a plurality of tables, each of which defines processing to a predetermined reception packet, based on a condition and a processing content which are defined in each table, and which refers to said opening flow table to determine the processing content to the reception packet;
- and
- an action functioning section which executes processing to said reception packet based on the determined processing content.
A switch control method which is executed in an open flow switch, said switch control method comprising:
- configuring an open flow table by logically combining a plurality of tables, each of which defines processing to a reception packet, based on a condition and a processing content defined in each table;
- referring to said open flow table to determine the processing content to the reception packet;
- and
- executing the processing of the reception packet based on the determined processing content.
A non-transitory recording medium in which a program is stored which makes a computer used as a switch execute:
- configuring an open flow table by logically combining a plurality of tables, each of which defines processing to a given packet, based on a condition and a processing content defined in each table;
- referring to said open flow table to determine the processing content to the reception packet;
- and
- executing the processing of the reception packet based on the determined processing content.
