A control packet transmission system includes a first switch device that, during a first time period, generates and transmits first control packets to a second switch device. Furthermore, a third switch device is provided that, during the first time period, generates and transmits third control packets to the second switch device, and transmits a copy of those third control packets to the first switch device. The first switch then generates respective first hash values using each of the first and third control packets, and generate a first consolidated hash value using each of the respective first hash values. During a subsequent second time period, the first switch device may determine that control data exchanged during the first and second time periods is the same and, in response, transmit the first consolidated hash value to the second switch device in place of any control packets transmitted to the second switch device.
