Extensive logging #3

Open cyrill-k opened 5 years ago

cyrill-k commented 5 years ago

Additional logging:

Change between CC phases for each subflow (slow start, congestion avoidance, recovery)
cwnd before & after for all ACK & LOSS events in the congestion controller
Algorithm specific parameters: (e.g., alpha, best paths, collected paths, left term of increase in OLIA)

cyrill-k commented 5 years ago

Changed logs:

LOSS_ALGORITHM_RTT id newRtt → UPDATED_RTT id sendDelta ackDelayTime newSmoothedRtt
LOSS_ALGORITHM_ACK id bytesAcked cwndAfter → CC_ACK id pktNumber bytesAcked cwndBefore cwndAfter
LOSS_ALGORITHM_LOSS id bytesLost cwndAfter ("SS"|"CA") → CC_LOSS id pktNumber bytesLost cwndBefore cwndAfter

New logs:

CC_STATE_CHANGED id before after (before/after is one of "rec", "ss", "ca")
CC_INCREASE_TERM id algorithm totalRounded leftTerm rightTerm alpha potentialTcpThroughputIndicator (potentialTcpThroughputIndicator is l/rtt^2, algorithm is "olia")
