| Traffic Engineering Task Force |
Scope of the task forceTraffic engineering involves adapting the routing of traffic to the network conditions, with the joint goals of good user performance and efficient use of network resources The task force is co-chaired by O. Bonaventure (UCL, Belgium) and G. Leduc (ULg, Belgium) Research topics
Objective of the task forceWe propose to integrate all our TE methods in an open source TE toolbox, referred to as the TOTEM toolbox, which can be seen as a repository of methods. This seems to be an ideal goal for a NoE, since it federates several contributions into a toolbox that would be more valuable that the sum of its pieces. E-NEXT partners interested in this task force are invited to integrate their TE methods in the toolbox. This toolbox will NOT deal with measurements (which are covered by task force T4.1), but will have interfaces to import such data (e.g. topologies, traffic matrices) and to export data (e.g. to configure network devices). The toolbox can be integrated as an on-line tool in an operational network, or be used off-line (e.g. to simulate some network). It can be used to compare various algorithms on the same benchmarked data, or to compare methods against exact solutions. Some experiments with (a subset of) the toolbox can also be realized on some testbeds set up by some partners. Milestones of the task forceThis task force was proposed during the E-NEXT plenary meeting on the 25-26th of Feb. 2004. The Kick-Off meeting was held in Paris on the 15th of April 2004. Several partners have then started to work on the following joint paper, which presents in an integrated way the E-NEXT activities on traffic engineering and their federation in a common open source toolbox:
The second meeting of the task force took place on the 28th of September 2004 in Barcelona as part of the WG4 meeting jointly organized with the E-NEXT plenary meeting and the QoFIS conference. It was decided to propose a WG4 Collaborative Experimental Research Activity with a WG4 budget of 7000 EUR. The third meeting took place on the 31st of March 2005 in Naples as part of the WG4 meeting jointly organized with the E-NEXT plenary meeting. The WG4 Collaborative Experimental Research Activity had been accepted and we agreed to support several short term scientific missions with the outcome of integrating several new tools in the TOTEM toolbox. Five of them have been funded (1 visit of ULg to CINI/UoN, 2 visits of CINI/UoN to ULg, and 2 visits of FTW to ULg) The fourth meeting took place on the 28th of September 2005 in Toulouse as part of the WG4 meeting jointly organized with the E-NEXT plenary meeting and the Co-Next Conference. A sixth short term scientific mission was decided and funded (1 visit of UDelft to ULg). Outcome of the task forceThe concrete outcome of task force 4.2 is an extended version of the open source TOTEM toolbox containing the following components: 1. Intra-Domain tools 1.1 MCNF (Multi Commodity Network flow), developed by ULg 1.2 Pure IP methods:
1.3 MPLS methods:
1.4 Hybrid IP/MPLS methods:
2. Inter-Domain tools
3. Topology and traffic matrix generators, developed by UCaL and ULg 4. Software Architecture, developed by ULg |
