Achieving High Throughput in Low Multiplexed, High Bandwidth, High Delay Environments

This paper explores combining ECN bits and loss feedback to achieve a high throughput connection in a high bandwidth, low multiplexed environment. In the scheme, a TCP source reacts differently on receiving an ECN than it does on inferring a packet loss in terms of congestion window update. Coupled with...

A Window-Based Flow Control Mechanism Based on TCP Vegas With Explicit Congestion Notification

A window-based flow control mechanism is a sort of feedback-based congestion control mechanisms, and has been widely used in TCP/IP networks. Recently proposed TCP Vegas is another version of the TCP mechanism and has potential to achieve much better performance than current TCP Tahoe and Reno. This paper focuses on...

Explicit Congestion Notification (ECN) for TCP/IP

When routers become congested to the point in which their incoming packet buffers fill and they begin dropping packets, the effect on the network is reduced bandwidth, an impact on loss or time-sensitive traffic flows, and possibly link idle time after the congestion occurs. Explicit Congestion Notification ECN for TCP/IP...
