摘要： Systems, methods and media for detecting outbound Nagling on a TCP network connection are disclosed. Embodiments may include creating by a sender computer one or more segments to be transmitted to a receiver computer and determining by the sender computer whether any of the one or more segments to be transmitted are small segments and determining whether a previously transmitted small segment is unacknowledged by the receiver computer. If the previously transmitted small segment is unacknowledged by the receiver computer and at least one of the segments to be transmitted is a small segment, embodiments may also include detecting by the sender computer a Nagling condition on the network connection. Further embodiments may include modifying a Nagle algorithm configuration of the network connection in response to the detected Nagling condition by turning off the Nagle algorithm or reducing a delayed acknowledgement timer for the network connection.

摘要： Systems, methods and media for detecting Nagling on a TCP network connection are disclosed. Embodiments may generally include a system with a Nagle detection threshold determiner for determining a Nagle detection threshold based on the network connection. The system may also generally include a Nagle detection module in communication with the Nagle detection threshold determiner for observing a small segment at a second time following an acknowledgement indicative of a Nagling condition at a first time, wherein the Nagle detection module also may detect a Nagling condition if the difference between the second time and the first time is less than or equal to the Nagle detection threshold. The system may be a receiver computer or a network computer. The system may also generate and transmit a notification of the Nagling condition, increment a Nagle monitor counter, or save an indication of the Nagling condition in a log.
