  • Lossless connection failover for mirrored devices with reduced inter-device messaging
    Patent number: 10419272
    Abstract: If there are mirrored WAN optimization devices, a master WAN optimization device sends a datagram received from a source across the WAN and sends a copy of the datagram to a mirroring WAN optimization device. When the mirroring WAN optimization device ACKs the mirrored datagram, the master WAN optimization device ACKs the host. When the master WAN optimization device receives the ACK from the WAN, the ACK is forwarded to the mirroring WAN optimization device, which deletes the mirrored datagram. Alternatively, the mirroring WAN optimization device can receive the datagram from the source, store it and forward it to the master WAN optimization device, which sends the datagram across the WAN and sends an ACK to the host. When the ACK from the WAN is received, the master WAN optimization device forwards the ACK to the mirroring WAN optimization device, when then deletes the mirrored datagram.
