The PROXIDOR Service

Several applications, such as peer-to-peer (P2P), content
distribution and realtime services rely on selection mechanisms in
order to select the peer or server from which to request the service.
Examples of such services are: file sharing, media streaming and
voice gateways.

Application-layer selection algorithms do not typically take into
account network-layer topology information; either that information
is unavailable to them, or when such information is available (e.g.,
from BGP Looking Glass servers), it does not include sufficient

Interdomain Traffic Engineering in a Locator/Identifier Separation Context

dsaucez — Fri, 12 Sep 2008 15:02:33 +0000

The Routing Research Group (RRG) of the Internet Research Task Force
(IRTF) is currently discussing several architectural solutions to
build an interdomain routing architecture that scales better than the
existing one. The solutions family currently being discussed concerns the addresses
separation into locators and identifiers, LISP being one of them.
Such a separation provides opportunities in terms of traffic
engineering. In this paper, we propose an open and flexible solution
that allows an ISP using identifier/locator separation to engineer its

Why should the Traffic Optimization not be restricted to the Application-Layer?

The Application-Layer Traffic Optimization (ALTO) problem is being discussed within the IETF and more globally by the research community and some enterprises. In this memo, we argue that it is important to conceive general-purpose mechanisms to solve this problem. By general-purpose we say not only application independent but also layer independent mechanism. The generality can be obtained because the underlying problem is the same regardless the application or the layer.
