GOOSE message transmission delay jitter suppression method
2013
The invention belongs to the power system communication technical field and provides a GOOSE message transmission delay jitter suppression method. According to the GOOSE message transmission delay jitter suppression method, a backup retransmission mechanism is adopted to back up normal frames which are being transmitted by a port to a buffer zone; if GOOSE messages are transmitted to the port, the transmission of the normal frames stops, and the forwarding of the GOOSE messages begins; and after the GOOSE messages have already been forwarded, the normal frames which are backed up in the buffer zone previously are re-transmitted. With the GOOSE message transmission delay jitter suppression method adopted, jitter caused by forward delay of the GOOSE messages can be avoided, wherein the forward delay is caused by a situation where the normal frames occupy the port; and at the same time, the GOOSE message transmission delay jitter suppression method is compatible with existing various Ethernet standards, software/hardware modification is not required to be performed on terminal equipment.
