The Addition of Explicit Congestion Notification (ECN) to IP
This memo specifies the incorporation of ECN (Explicit Congestion Notification) to TCP and IP, including ECN's use of two bits in the IP header.

The proposals in this document are experimental. While they may be deployed in the current Internet, they do not represent a consensus that this is the best method for high-speed congestion control.Expand
Equation-based congestion control for unicast applications
TLDR
A mechanism for equation-based congestion control for unicast traffic that refrains from reducing the sending rate in half in response to a single packet drop, and uses both simulations and experiments over the Internet to explore performance. Expand
Wide area traffic: the failure of Poisson modeling
TLDR
It is found that user-initiated TCP session arrivals, such as remote-login and file-transfer, are well-modeled as Poisson processes with fixed hourly rates, but that other connection arrivals deviate considerably from Poisson. Expand
Promoting the use of end-to-end congestion control in the Internet
TLDR
It is argued that router mechanisms are needed to identify and restrict the bandwidth of selected high-bandwidth best-effort flows in times of congestion, and several general approaches are discussed for identifying those flows suitable for bandwidth regulation. Expand
TCP Friendly Rate Control (TFRC): Protocol Specification
TLDR
TFRC is a congestion control mechanism for unicast flows operating in a best- effort Internet environment that has a much lower variation of throughput over time compared with TCP, making it more suitable for applications such as telephony or streaming media where a relatively smooth sending rate is of importance. Expand
Simulation-based comparisons of Tahoe, Reno and SACK TCP
TLDR
The congestion control algorithms in the simulated implementation of SACK TCP are described and it is shown that while selective acknowledgments are not required to solve Reno TCP's performance problems when multiple packets are dropped, the absence of selective acknowledgements does impose limits to TCP's ultimate performance.

  • 20 October 1994
TLDR
The first part proposes new guidelines for TCP's response to ECN mechanisms (e.g., Source Quench packets, ECN fields in packet headers) and uses simulations to explore the benefits and drawbacks of ECN in TCP/IP networks. Expand
Adaptive RED: An Algorithm for Increasing the Robustness of RED's Active Queue Management
The RED active queue management algorithm allows network operators to simultaneously achieve high throughput and low average delay. However, the resulting average queue length is quite sensitive toExpand
