The Classic recovery implementation.
Introspection did not find any typical Config paths.
Classic recovery refers to the two well-established recovery algorithms, namely, NewReno (RFC 6582) and SACK based recovery (RFC 6675).
The idea of the algorithm is that when we enter recovery, we set the congestion window value to the slow start threshold and maintain it at such value until we are fully recovered (in other words, until the highest sequence transmitted at time of detecting the loss is ACKed by the receiver).
No Attributes are defined for this type.
No TraceSources are defined for this type.
Size of this type is 32 bytes (on a 64-bit architecture).

overridevirtual |
Performs recovery based on the recovery algorithm.
The function is called on arrival of every ack when TcpSocketState is set to CA_RECOVERY. It performs the necessary cwnd changes as per the recovery algorithm.
