Network Control Plane and the MUPPET project Mauro Campanella INFN-GARR

M. Campanella - GARR - TNC pag. 2 Network Control plane Which protocols and architectures are around ? 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,…)

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

M. Campanella - GARR - TNC pag. 7 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

Confidential MUPPET Multi-Partner European Test Beds for Research Networking FP6 IST , 2nd Call, “Research Networking Test Beds”

M. Campanella - GARR - TNC pag. 11 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 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
