  1. Brief demo description

This demo shows a split architecture based control scheme for an operator’s end-to-end MPLS network, developed within the "Split architecture carrier grade networks" (SPARC) 7th framework EU project. In our proof-of-concept research work we make use of open-source components (like NOX) and extend them to control an access/aggregation network with a centralized controller that also interworks with a legacy distributed MPLS core network (see attached Figure 1). We show (i) unicast video stream setup as a result of interworking with the core MPLS network, including the use of OSPF and LDP, (ii) multicast video stream with dynamic subscription/unsubscription and optimal transmission tree recalculation, (iii) LLDP based controller driven restoration versus data plane managed protection.

The SPARC project activities also include looking at ways to make the centralized controller carrier grade by running a detailed evaluation of the scaling and resiliency of the Split Architecture.

  1. List of equipment that will need AC connections (e.g. laptop, switch hardware prototype, monitor). (Just put in the number of connections needed if your demo description already lists the equipment): 7 (1 router, 2 pc, 3 laptop, 1 monitor)
  1. Number of wired network connections (include required bandwidth if significant): None
  1. Number of wireless network connections (include required bandwidth if significant): None
  1. Number of static addresses needed (if any): None
  1. Projector (y/n) (Bring your own projectors if feasible): No
  1. Monitor (y/n, specify VGA or DVI) (Specify resolution only if your software has resolution restrictions): Yes, VGA
  1. Number of posters (max size poster boards are 30" x 40"): One
  1. Description of any special requests (include any non-commercial network connectivity needs, projects you'd like to be located near, etc.):

A single poster without hardware is not suitable to present our demo. The layout can be a bit more compact compared to the attached Figure 2.
