Abstract

This memo presents two recommendations to the Internet community concerning measures to improve and preserve Internet performance. It presents a strong recommendation for testing, standardization, and widespread deployment of active queue management in routers, to improve the performance of today's Internet. It also urges a concerted effort of research, measurement, and ultimate deployment of router mechanisms to protect the Internet from flows that are not sufficiently responsive to congestion notification.

Abstract

This memo presents two recommendations to the Internet community

concerning measures to improve and preserve Internet performance.

It presents a strong recommendation for testing, standardization,

and widespread deployment of active queue management in routers,

to improve the performance of today's Internet. It also urges a

concerted effort of research, measurement, and ultimate deployment

of router mechanisms to protect the Internet from flows that are

not sufficiently responsive to congestion notification.

1. INTRODUCTION

The Internet protocol architecture is based on a connectionless end-

to-end packet service using the IP protocol. The advantages of its

connectionless design, flexibility and robustness, have been amply

demonstrated. However, these advantages are not without cost:

careful design is required to provide good service under heavy load.

In fact, lack of attention to the dynamics of packet forwarding can

result in severe service degradation or "Internet meltdown". This

phenomenon was first observed during the early growth phase of the

Internet of the mid 1980s [Nagle84], and is technically called

"congestion collapse".

The original fix for Internet meltdown was provided by Van Jacobson.

Beginning in 1986, Jacobson developed the congestion avoidance

mechanisms that are now required in TCP implementations [Jacobson88,

HostReq89]. These mechanisms operate ...
