Active-TCP congestion control approach
一种主动TCP拥塞控制方案

Based on TCP Reno, a widely used TCP version, proposed an active TCPcongestion control approachnamed Active-TCP. Besides the traditional passive congestion control manners, Active-TCP added an active congestion control manner, i.e., the congestion window may be decreased actively when some given conditions were satisfied before the congestion really occurs. Investigated Active-TCP performances through simulations. Comparing with TCP Reno, the throughput may be improved and the retransmit probabilitymay be decreased. Active-TCP can coexist with TCP Reno very friendly, and they can compete network resources fairly. In addition, Active-TCP may be obtained through a little modification fromTCP Reno at the sender side, so Active-TCP can be easily developed and the addition overheads are very low.
