DECoupled Application Data Enroute (DECADE)
Abstract
Content distribution applications, such as those employing peer-to-
peer (P2P) technologies, are widely used on the Internet and make up
a large portion of the traffic in many networks. Often, however,
content distribution applications use network resources
inefficiently. One way to improve efficiency is to introduce storage
capabilities within the network and enable cooperation between end-
host and in-network content distribution mechanisms. This is the
capability provided by a DECoupled Application Data Enroute (DECADE)
system, which is introduced in this document. DECADE enables
applications to take advantage of in-network storage when
distributing data objects as opposed to using solely end-to-end
resources. This document presents the underlying principles and key
functionalities of such a system and illustrates operation through a
set of examples.
