 /*
  * Binary Increase Congestion control for TCP
- *
+ * Home page:
+ *      http://netsrv.csc.ncsu.edu/twiki/bin/view/Main/BIC
  * This is from the implementation of BICTCP in
  * Lison-Xu, Kahaled Harfoush, and Injong Rhee.
  *  "Binary Increase Congestion Control for Fast, Long Distance
  *  Networks" in InfoComm 2004
  * Available from:
- *  http://www.csc.ncsu.edu/faculty/rhee/export/bitcp.pdf
+ *  http://netsrv.csc.ncsu.edu/export/bitcp.pdf
  *
  * Unless BIC is enabled and congestion window is large
  * this behaves the same as the original Reno.
