Improving The Performance Of Interactive TCP Applications Using Service Differentiation
White Papers Interactive TCP applications, such as Telnet and the Web, are particularly sensitive to network congestion. Indeed, congestion-induced queuing and packet loss can be a significant cause of large delays and variability, thereby decreasing user...

BicTCP Implementation In Linux Kernels
White Papers TCP is a protocol that regulates network congestion and best e ort fairness. Many attribute the success of the internet to the congestion avoidance algorithms in the original TCP. However, TCP has performance deficiencies [R03] and many New-TCP...

TCP Adaptive RTO To Improve TCP Performance In Mobile Ad Hoc Networks
White Papers TCP AR distinguishes routes failures from network congestion and adapts the RTO's value to network conditions. With the assumption that all packet losses are due to congestion, TCP performs poorly in such an environment.

TCP-DCR: Making TCP Robust To Non-Congestion Events
White Papers The strength of TCP lies in the fact that it tries to mitigate congestion in the network by reducing the sending rate in response to loss of packets. As a consequence, severe penalty is paid in terms of degraded performance in networks where the...

A Framework For Managing Emergent Transmissions In IP Networks
White Papers Theories and experiments have shown that average end-to-end delay of flows increases and TCP becomes inefficient and instable during network congestion period, regardless of which queue management and packet scheduling mechanism are being applied.

Background TCP Data Transfer With Inline Network Measurement
White Papers ImTCP-bg sets the upper limit of the congestion window size of the sender TCP based on the results of the inline network measurement, which measures the available bandwidth of the network path between the sender and receiver hosts.

Generalized Window Advertising For TCP Congestion Control
White Papers Congestion in the Internet is a major cause of network performance degradation. GWA exploits the notion of end-host - network cooperation, with the congestion level notified from the network to end hosts.

A Fairness Analysis Of LAN/WAN Protocol Relays
White Papers Relay systems are critical systems in the overall performance of the network because they are the points where network congestion can be build up or avoided. Particularly, when the interconnected subnetworks have very dissimilar bandwidths...

Explicit Congestion Notification (ECN) For TCP/IP
White Papers 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...
