System and techniques for transmission controller protocol (TCP) receiver controller interruption mitigation are described herein. At a receiver device, a physical link degradation indication of a physical link may be obtained. In response to the physical link degradation indication, a transmission queue may be measured to determine bufferbloat that is a result of a temporary blockage of the physical link. The receiver device may then transmit, to a second device on the physical link, a TCP receive window size update that is smaller than a previous TCP receive window size.
