    摘要： Discovery of intermediate network devices is performed using a technique that piggybacks upon the existing standard TCP (Transport Control Protocol) “SACK” (Selective Acknowledgment) option in a SYN/ACK packet so that discovery information may be shared between pair-wise-deployed peer intermediate devices when a TCP/IP connection (Transport Control Protocol/Internet Protocol) is first established between network endpoints using a conventional three-way handshake. Use of the SACK option is combined with another technique which comprises modifying the original 16-bit value of the TCP receive window size to a special arbitrary value to mark a SYN packet as being generated by a first peer device. The marked SYN when received by the second peer device triggers that device's discovery information to be piggybacked in the SACK option of the SYN/ACK packet. The first device then piggybacks its discovery information in the SACK option of the ACK packet which completes the three-way handshake.

    摘要： Aspects of the subject matter described herein relate to selecting a source interface with which to establish a connection. In aspects, a profile for each network location a host has seen is maintained in a data store. The profile includes information about the network interfaces available to a source host at the network location. This information indicates, among other things, the reliability of each interface of the source host. Based on the profile, an interface is selected with which to establish a connection. If the interface is unsuccessful in establishing the connection, the interface is de-prioritized and another interface may be selected.

    摘要： Techniques are provided for adjusting to changes to the latency for a connection between two nodes on a network. In accordance with some embodiments, when a transmitting node encounters a retransmission timeout for a packet sent to a receiving node, the latency for the connection is newly measured and used to calculate a new retransmission timeout period for subsequent transmissions by the transmitting node. In some embodiments, the latency is not newly measured if the transmitting node receives a selective acknowledgement from the receiving node, since a selective acknowledgement may indicate that congestion on the network is only temporary.
