Network Control plane
Lots of interest because:
• request for dynamic network
topologies (Bandwidth on
Demand, Grids, virtual
communities)
• e2e performance guarantees
• fiber abundance and DWDM
• mixed packet and circuit
switched network
• specific application (HEP,
RadioTelescopes, HDTV,…)
Which protocols
and
architectures
are around ?

Loads of Challenges
• goal is e2e worldwide
AAA
• stacking of different protocol (interference)
• signalling protocols (types and intrinsic
limitations like speed of light)
• scaling
• Routing architectures
• resource brokers
• information systems
• “time quantum”, how long is a jiffy
• …

Control Plane Objectives
User Controlled LightPath Objects
• No central control plane
• Allow institutions to integrate wavelengths and fiber from different
suppliers and integrate with institution's network management domain
– And offer VPNs to users
• Create discipline specific re-configurable IP networks
– Multihomed network which bypasses firewalls with direct connect to servers
and routers
• User controlled traffic engineering
– Active replacement for Sockeye and Route Science
– Alternative to MPLS
• Extend Internet e2e principle to circuit and control planes
• Maybe (but not likely) reservation and leasing of wavelength resources
• Maybe (but not likely) switched optical networks

Multi-Partner European Test Beds for Research

“Research Networking Test Beds”
Confidential
MUPPET: Project Objectives
Main Goal
Integration and validation, in the context of userdriven large scale test beds, of state-of-the-art
on-demand circuit switching techniques, and in
particular of ASON/GMPLS, as enablers for future
upgrades to European research infrastructures.
(note: ASON covers multiple transport technologies, such as WDM, OTH, SDH)

The Project will create a large experimental environment that will be used to assess
the network solutions under investigation, and that will be offered as an open test
platform to other European research projects and users.
The test bed will represent a multi-layer network based on IP/MPLS and
ASON/GMPLS technologies, equipped with a unified control plane and designed to
support the highly demanding applications of the European research community

Key aspects
•Already available Test-beds:
– 2 ASON/GMPLS focussed test-beds: TILAB(LION),
T-Systems (GSN)
– 1 broad-band end-user focussed test-bed (ACREO)
– 2 IP/MPLS focussed test-beds (Telefonica, PSNC)
– variety of ultra-broadband users and applications  User
Community
– interconnection of test-beds
The MUPPET consortium already identified additional research
users to which offer an access to the test beds and field trials,
for joint experiments, assessment of the proposed architecture
and solutions, dissemination of the Project knowledge

Summary of research benefits
customers
• user control of network resources (VPNs)
• flexible broadband on demand services including QoS guarantees
network providers
• simplification of operational processes
• efficient network solutions leading to cost savings
• open platform which is flexible to support services not foreseen
beforehand (service neutral approach)
• end to end services in an environment based on different domains
which are operated autonomously
network requirements
• network functions supporting the application requirements
• inter-operability between vendors and operators domains to be
able to build a pan-European research backbone
• Prove of solutions and dissemination of results
