  • Service aware switch-over of TCP-flows
    Patent number: 10616361
    Abstract: A method is implemented by a transparent proxy to support graceful switchover in a network, where the transparent proxy proxies one or more Transmission Control Protocol (TCP) connections involving a destination Internet Protocol (IP) address. The method includes starting a switchover timer for the destination IP address in response to receiving an instruction from an Application Flow Controller (AFC) to start the switchover timer for the destination IP address and transmitting an indication to the AFC that all of the one or more TCP connections involving the destination IP address that are proxied by the transparent proxy have ended or the switchover timer for the destination IP address has expired in response to a determination that all of the one or more TCP connections involving the destination IP address that are proxied by the transparent proxy have ended or the switchover timer for the destination IP address has expired.
