摘要： A method for detecting and reducing packet drops in a communications system may include receiving a first packet having a sequence number, determining if a second packet having a sequence number immediately preceding the sequence number of the first packet is lost, and/or determining if a third packet having a sequence number immediately preceding the sequence number of the second packet is lost. A counter may be incremented if the second and third packets are determined as lost. An amount of time required before detecting link activity after an end of a previous frame may be reduced if the counter violates the count threshold and the amount of time has not been previously reduced. A lower link speed may be negotiated if a current link speed is above a negotiable threshold and the amount of time required before detecting link activity has been previously reduced.

摘要： An approach is provided to improve network efficiency. A send segment size, such as a maximum segment size (MSS), that corresponds to data segments being sent to a receiver over a computer network. A data block is identified in a send buffer and the data block includes more than one data segments. Based on the determined send segment size, all but a remaining data segment of the data segments are sent to the receiver. The sent data segments are each the determined send segment size and the remaining data segment is smaller than the send segment size. The remaining data segment is sent to the receiver in response to identifying that the remaining data segment is a portion of the data block.
