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 networkcapacity evolution

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

Not just the bandwidth!Innovations: Paradigm shifts

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

ΣB ≈ 40 Gb/s ΣC ≈ 100 Gb/sA

Do these need an IP network?

Do we want to build an IP network for them?

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

SURFnet6 approach

- Acquire fiber: SURFnet6 is based on 8000+ kilometres of fiber pairs

- Create the world’s first hybrid optical and packetswitched network

- Upgrade the ‘standard’ IP connections to 1/10 Gbit/s

- Introduce direct, fast, secure connectionsbetween connected institutions (bypass the costly routers)

LIGHTPATHS!!!

Lightpaths

Light paths - whatPoint-to-Point (L1) connection ‘Virtual’ lambda!Edge port is mostly gigabit Ethernet (GE), will move to 10 GEAny 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 coreStorage, 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

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

Wanneer welk model (welk OPN)?1. Klein aantal sites

GEGE

- ‘Protected’ lichtpaden- Klein aantal sites wordt met elkaar verbonden- Een LAN over grote afstand- Full mesh

inefficient gebruik backbone, geen aggregatie capaciteitEen 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, butimplemented using TDM

- Hybrid means two different bits of equipment to createservices…

- Convergence would be nice

- SURFnet7 currently being investigated- Next Gen Ethernet?- PBT? MPLS? MPLS-TP? Anything Else?

The already-there future: Dynamic Lightpaths
