Time-Driven Early Discard (TED) to Improve the Fairness of TCP Congestion Control
White Papers The basic underlying idea is to set a deadline on packet service time in routers, beyond which packets are discarded. In fact, as demonstrated by the presented results, TCP connections traversing parts of the network with enough available capacity...
