-tcp_westwood - BOOLEAN
-        Enable TCP Westwood+ congestion control algorithm.
-        TCP Westwood+ is a sender-side only modification of the TCP Reno 
-        protocol stack that optimizes the performance of TCP congestion 
-        control. It is based on end-to-end bandwidth estimation to set 
-        congestion window and slow start threshold after a congestion 
-        episode. Using this estimation, TCP Westwood+ adaptively sets a 
-        slow start threshold and a congestion window which takes into 
-        account the bandwidth used  at the time congestion is experienced. 
-        TCP Westwood+ significantly increases fairness wrt TCP Reno in 
-        wired networks and throughput over wireless links.

-tcp_vegas_cong_avoid - BOOLEAN
-        Enable TCP Vegas congestion avoidance algorithm.
-        TCP Vegas is a sender-side only change to TCP that anticipates
-        the onset of congestion by estimating the bandwidth. TCP Vegas
-        adjusts the sending rate by modifying the congestion
-        window. TCP Vegas should provide less packet loss, but it is
-        not as aggressive as TCP Reno.

-tcp_bic - BOOLEAN
-        Enable BIC TCP congestion control algorithm.
-        BIC-TCP is a sender-side only change that ensures a linear RTT
-        fairness under large windows while offering both scalability and
-        bounded TCP-friendliness. The protocol combines two schemes
-        called additive increase and binary search increase. When the
-        congestion window is large, additive increase with a large
-        increment ensures linear RTT fairness as well as good
-        scalability. Under small congestion windows, binary search
-        increase provides TCP friendliness.
-        Default: 0
-
-tcp_bic_low_window - INTEGER
-        Sets the threshold window (in packets) where BIC TCP starts to
-        adjust the congestion window. Below this threshold BIC TCP behaves
-        the same as the default TCP Reno. 
-        Default: 14
-
-tcp_bic_fast_convergence - BOOLEAN
-        Forces BIC TCP to more quickly respond to changes in congestion
-        window. Allows two flows sharing the same connection to converge
-        more rapidly.
-        Default: 1
