Abstract
Being the widely used transport protocol in Internet, TCP might be influenced by the congestion occurred in those nodes (i.e., routers, IP/ATM access nodes, and ATM switches) along the travelling path. Since TCP relies on the end-to-end window-based mechanism to explain the congestion, there is limited room for intermediate network elements to explicitly contribute to the TCP control. However, in huge pipe networks, TCP might be ineffective because it starts decreasing its rate just after it senses packet's loss, implying that the network has already been congested somewhere. A general mechanism of delaying ACKs in congested nodes is presented in this draft to connect the traffic control of TCP with that of network elements. This mechanism can be considered as an enhancement to the currently prevalent TCP and referred to Fast-TCP. The basic idea of Fast-TCP arises from the fact that controlling ACK flows can indirectly affect the dynamics of TCP's behavior. ACK delay mechanism can be easily implemented in various network nodes where information of link utilization or buffer occupancy may be employed to notify the congestion. By using ACK delay policy at IP routers in a complex network, we present the simulation results to show that this policy achieves good TCP throughput and reduces the buffer requirement.
