Example - Traffic modelling

• Dynamic of the total input/output traffic
• Activity of the total input/output traffic
• Topological analysis of traffic

12
Simulation for large European testbeds
study the behaviour of different strategies for
user traffic engineering
with respect to

• inter-domain models
• application traffic models
• border router traffic models
• inter-domain topology.

13
Simulationgoal
discover optimization rules for assigning traffic
to inter-domain routes considering
MPLS/DiffServ interfaces
14
Simulation
For the GEANT testbed, simulation should show
different strategies for

• the assignment of application traffic to
  MPLS/DiffServ classes
• the assignment of AS traffic to MPLS/DiffServ
  classes
• keeping QoS in case of fall back situations, if
  a border router has a malfunction
• keeping QoS if an AS changes its routing policy.

15
Future activities

• Currently Specification phase
• Planning experimental use for European testbeds
• First prototype in spring of 2003
• International workshop on inter-domain
  performance and simulationplanned for February
