+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.
+	Default:0
+
+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

+tcp_default_win_scale - INTEGER
+	Sets the minimum window scale TCP will negotiate for on all
+	conections.
