Abstract
This paper describes the implementation and evaluation
of an operating system module, the Congestion Manager
(CM), which provides integrated network ow manage-
ment and exports a convenient programming interface
that allows applications to be noti ed of, and adapt to,
changing network conditions. We describe the API by
which applications interface with the CM, and the archi-
tectural considerations that factored into the design. To
evaluate the architecture and API, we describe our im-
plementations of TCP; a streaming layered audio/video
application; and an interactive audio application using
the CM, and show that they achieve adaptive behavior
without incurring much end-system overhead. All ows
