Detailed Description

Test case for congestion control algorithms with ABE.

This test verifies that when a TCP socket has ABE enabled, the congestion window value returned by its GetSsThresh() method will be calculated using the default BetaEcn value, and when ABE is disabled, the standard multiplicative decrease by half is used. ABE should only work for TcpCubic, TcpNewReno, TcpLinuxReno as specified in RFC-8511
