[Apn] Application Defined Networks

[Hesham ElBakoury <[e-mail]>]

In HotNet 2023 a paper about Application Defined Networking will be
presented.

*Abstract*
"With the rise of microservices, the execution environment of many cloud
applications has become a set of virtual machines or containers connected
by a flexible and feature-rich virtual network. We argue that the
implementation of such
virtual networks should be completely application-specific and not layered
on top of general-purpose network abstractions from the Internet age. Such
layering tends to more than double the latency and CPU usage of
applications. We propose application-defined networks in which developers
specify network functionality in a high-level language and a controller
generates a custom distributed implementation that runs across available
hardware and software resources.

Experiments with a preliminary prototype suggest that, compared to the
state of the art, ADN reduces latency by up to 20x and increases the
throughput by up to 6x."
