CONTROLLER, LOAD-BALANCING METHOD, NON-TEMPORARY COMPUTER-READABLE MEDIUM FOR STORING PROGRAM, COMPUTER SYSTEM, AND CONTROL DEVICE

摘要

A kind of OpenFlow networks include multiple controllers (1). Each controller (1) includes load control table (153) and load control unit (14). Load control table (153) controls at least one message number, and the OpenFlow networks of which each switch (2) have been received that more than the quantity of predetermined time and packet switch (2) more than the predetermined time to controller (1) control switch (2). When scheduled event occurs, there is processing load to be more than or equal to first threshold according to (1) another controller (1) under control of the place (2) of load control table (153) and at least one switch control by detection controller for load control unit (14) detection controller (1).
