Project abstract

In the last years, the expansion of the Internet traffic required a constant increase of router throughput and capacity of the links in IP backbone networks. In the next years, this increase will be achieved by WDM (Wavelength Division Multiplexing), providing multiple colors on a single fiber. To tackle the limitations of the classical shortest path routing, the development of MPLS (Multiprotocol Label Switching) took place. MPLS provides an architectural sublayer able to operate over any datalink infrastructure. The ATRIUM Consortium wishes to validate and experiment the above state of the art by deploying an advanced testbed that will additionally support QoS and fast restoration of link or node failures. ATRIUM will provide the research community with an advanced testbed containing the only European manufactured terabit router so far.

Project objectives

  • To develop an advanced testbed for the experiment and the validation of an ATR (Advanced Terabit Router) as a core
  • To design, assess and experiment with a set of unified traffic management algorithms and protocols necessary to operate successfully such an ATR in and MPLS- based and DiffServ-capable AS (Autonomous System)
  • To develop, prototype and assess a generic set of traffic engineering tools and protocols necessary to allow such ATR to operate as a border router in a DiffServ- capable, MPLS-based AS, interconnected with other ASs with similar capabilities.
  • To test the final version of the ATR with very demanding applications.

Funding

The project is partially supported by the European Commission in the IST (Information Society Technologies) framework. Project reference: IST-1999-20675

Schedule

The project started on January 1st, 2001 for a duration of 2.5 years.

Role of RUN in the project

RUN is WP3 leader on intra-domain traffic engineering. The goal of WP3 is advanced research on optimized decentralized traffic engineering algorithms. Examples are solutions for the dynamic calculation of LSPs, fast restoration in case of failures, and algorithms to provide QoS in DiffServ/MPLS networks. Besides theoretical studies, this WP will mainly assess its results by way of simulations.
