- NS2, two-way TCP:
ECN-Capability for SYN/ACK packets in two-way TCP
(tcp-full) in ns-2:
Agent/TCP/FullTcp set ecn_syn_ true
NS2, one-way TCP:
To enable ECN-Capability for SYN/ACK packets in one-way TCP in ns-2:
Agent/TCPSink set ecn_syn_ true
- As of 10/31/2008, ECN+/TryOnce has not been added to one-way TCP in ns-2.
NS2 validation tests with TCP (in tcl/test):
To run tests: ./test-all-ecn-ack
