Transport Optional Upgrade Release Transition Release Notes Announcement The F-RTO algorithm also responds to a spurious timeout. When the Retransmission Timeout (RTO) expires, F-RTO retransmits the first unacknowledged segment and monitors the incoming acknowledgments to determine if the timeout was spurious. Then, F-RTO determines whether to send new segments or retransmit the unacknowledged segments. The algorithm effectively reduces additional unnecessary retransmissions.
Transport Optional Upgrade Release Transition Release Notes Announcement The estimate of the available network capacity is reflected by the congestion validation window. Previously, this estimation becomes less accurate over time. This happens when the capacity that was previously used by a network-limited connection is used by other traffic. Thus the most recent knowledge of the TCP connection, regarding the state of the network path, is not reflected when the sender is application limited.
