Network Control Plane and the MUPPET project

Mauro Campanella INFN-GARR [email protected]

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 ?

Network Control Protocols Layering

Application IP transport IP (v4 and v6) Data link Physical not subject to network control TCP, SCTP, UDP(no control plane) RSVP BGP, OSPF, ISIS SONET/SDH (multilink ) CMIP X-NNI no multilink control protocols SNMP M. Campanella - GARR - TNC 2004 - pag. 3

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 • … M.

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 M.

MUPPET

Multi-Partner European Test Beds for Research Networking

FP6 IST-511780, 2nd Call, “Research Networking Test Beds” Confidential

MUPPET: Project Objectives Main Goal

Integration and validation, in the context of user driven 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 M. Campanella - GARR - TNC 2004 - pag. 12

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 M.

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 M.
