Routing and Provisioning VPNs Based on Hose Traffic Models and/or Constraints

This paper investigates various questions associated with routing and provisioning Virtual Private Networks (VPNs) based on hose traffic models or constraints, i.e., using aggregate (hose) traffic characterizations in/out of VPN end-points. This appears to be a promising simple approach to dealing with traffic engineering for VPNs. The paper evaluates the possible efficiencies derived from spatial multiplexing, i.e., over possibly varying routings of traffic loads consistent with hose specifications, and temporal multiplexing, i.e., statistical multiplexing of bursty loads, on shared VPN resources.
