Agenda - 9:30 Welkom! (Bram) - 9:40 SURFnet lichtpaden en meer (Bram) - 10:20 Optische Netwerken (Roeland) - 11:00 BREAK (maar een korte) (jullie) - 11:10 Operations in SURFnet (Stavroula) - 11:40 BGP in de praktijk (Jac): - 12:20 klaar, broodjes (opnieuw jullie)

Introductie! SURFnet overview

Introducing SURFnet - Dutch National Research & Education Network (NREN) - Not for profit organization, 75 employees - 180 connected institutions, 750.000 end-users - Business-model: - Innovation by project subsidies - Operations by tariffs from institutions

SURFnet network capacity evolution - Every generation a new network technology or architecture - Bandwidth as driver - Moving towards simpler architectures (KIS)

Not just the bandwidth! Innovations: Paradigm shifts Lambdas SURFnet6 network DWDM SURFnet5 network POS SURFnet4 network ATM SURFnet4 project GigaPort GigaPort Next Generation 1995 1999 2003 2008 Next generation is not a simple extrapolation of current networks

SURFnet6: the big idea - A: End users: web, e-mail - B: Institutions: applications, VPNs, shared service center - C: Researchers: computing, data grids, virtual-presence # u s e r s A Required capacity per user category: ΣB 40 Gb/s ΣC 100 Gb/s ΣA 20 Gb/s Do these need an IP network? Do we want to build an IP network for them? B C ADSL This slide courtesy of Cees de Laat BW requirements GigE

SURFnet6 highlights - World s first nationwide hybrid network, truly collapsed IP backbone (routers at 2 locations only) - Based on 8000+ km of SURFnet-owned managed dark fiber, - IPv4 and IPv6, unicast and multicast, plus lightpath provisioning, over a single transmission infrastructure

Services on SURFnet6 SURFnet6 IP routed services Lightpath services IPv4 IPv6 dynamic static unicast multicast unicast multicast single OPN lightpath

Not just networks - Services Portfolio This menu provides an overview of the SURFnet services Overview: -Network infrastructure -Security -Authentication & authorization -Group communication -Content delivery -Help and monitoring 10

SURFnet6 approach - Acquire fiber: SURFnet6 is based on 8000+ kilometres of fiber pairs - Create the world s first hybrid optical and packet switched network - Upgrade the standard IP connections to 1/10 Gbit/s - Introduce direct, fast, secure connections between connected institutions (bypass the costly routers) LIGHTPATHS!!!

Make the network ready - SURFnet6: DWDM on dark fiber Muenster Fiber Network

Lightpaths Light paths - what Point-to-Point (L1) connection Virtual lambda! Edge port is mostly gigabit Ethernet (GE), will move to 10 GE Any effective rate (< 1G or 10G) possible Light paths why Enable creation of Optical Private Networks (OPN) Divert high-bandwidth pt-to-pt streams from routed core Storage, other applications Enable network as integral part of scientific instruments

Lightpaths: Current implementation - Standard LAN interface (GE, 10GE) - Uses the qualities of the transport network to achieve - Performance: capacity, availability - Security: OSI L1 - Flexibility: locations, topologies - Simplicity: transparent, predictable/fixed latency - Costs of usage GE GE

Making Lightpaths reliable Model 1: Single GE OME OME GE Model 2: path protected GE OME working OME GE protecting

More models Model 3: redundant not protected GE OME working OME GE GE GE working Model 4: let s have it even more reliable GE OME working 1 OME GE GE protecting 2 protecting 1 working 2 GE

Making networks with lightpaths? - Designing a network to work with lightpaths demands some attention - Simple solution: direct point to point between two boxes --> not really a network - Complex solution: real L2 network??? - Routed solution, but a single admin domain

GE Wanneer welk model (welk OPN)? 1. Klein aantal sites GE - Protected lichtpaden - Klein aantal sites wordt met elkaar verbonden - Een LAN over grote afstand - Full mesh inefficient gebruik backbone, geen aggregatie capaciteit Een poort per andere site -- N x (N-1) totaal aantal poorten - Consolidatie infrastructuur mogelijk, maar niet noodzakelijk eerste doel - Erg eenvoudig design ( plug and play ) - Resiliency verbindingen volledig in netwerk

Wanneer welk model (welk OPN)? 2. Groot aantal sites Aggregatie site 1 Aggregatie site 2... - Redundant => 2 x enkelvoudige lichtpaden! - Groot aantal sites wordt met hubs verbonden => 4N poorten - Efficienter gebruik backbone, minder poorten voor groot aantal sites - Aggregatie capaciteit - Consolidatie infrastructuur mogelijk - Data centers kunnen met grotere capaciteit ontsloten worden - Resiliency verbindingen volledig in klant apparatuur - Netwerk falen leidt tot uitval verbinding

The (near!) future, part 1: Next Gen Ethernet - Currently lightpaths are GE / 10 GE terminated, but implemented using TDM - Hybrid means two different bits of equipment to create services - Convergence would be nice - SURFnet7 currently being investigated - Next Gen Ethernet? - PBT? MPLS? MPLS-TP? Anything Else?
