BIC TCP

For these networks, BIC has significant advantage over previous congestion control schemes in correcting for severely underutilized bandwidth.

[1] BIC implements a unique congestion window (cwnd) algorithm.

When a network failure occurs, the BIC uses multiplicative decrease in correcting the cwnd.

[2] BIC TCP is implemented and used by default in Linux kernels 2.6.8 and above.

The default implementation was again changed to CUBIC TCP in the 2.6.19 version.
