Abstract
In one embodiment, an apparatus comprises logic encoded in one or more tangible media for enhancing transmission reliability of monitored data. The logic is operable to receive a plurality of segments for transmission over a TCP connection to a network node, where the TCP connection is associated with a transmit queue and a retransmit queue. The logic is also operable to detect a transmission anomaly on the TCP connection to the network node, and in response to detecting the transmission anomaly, is operable to perform any one of: store segments into a persistent buffer prior to transferring the segments into the transmit queue; copy segments from the retransmit queue into the persistent buffer, where the segments have been transmitted but not yet acknowledged by the network node; and copy segments from the transmit queue into the persistent buffer, where the segments have not yet been transmitted to the network node.
