recovery abstract class
Introspection did not find any typical Config paths.
The design is inspired by the TcpCongestionOps class in ns-3. The fast recovery is split from the main socket code, and it is a pluggable component. Subclasses of TcpRecoveryOps should modify TcpSocketState variables upon three condition:
Each condition is represented by a pure virtual method.
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).

pure virtual |
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.

deliveredBytes | bytes (S)ACKed in the last (S)ACK |
Implemented in ns3::TcpClassicRecovery, and ns3::TcpPrrRecovery.

pure virtual |
Performs variable initialization at the start of recovery.
The function is called when the TcpSocketState is changed to CA_RECOVERY.

dupAckCount | duplicate acknowldgement count |
unAckDataCount | total bytes of data unacknowledged |
deliveredBytes | bytes (S)ACKed in the last (S)ACK |
