1 Strategy for SWITCH's next generation optical network Terena Network Architecture Workshop 2012 Felix Kugler, Willi Huber SWITCH 2012
2 Introduction! The project for the SWITCHlan renewal was formally accepted on November 15, no detailed concept is available yet we present our vision, goals, and the rough concepts 2
3 Agenda! where we are today where we want to go how to get there fibers and optical transmission switching layer summary 3
4 SWITCHlan mid 2012! 11 years since first light 2500 km of fiber pairs ~60 PoPs regional links 1Gbps few with 10Gbps core backbone DWDM lambdas max 10Gbps/lambda hotspots : areas with largest bandwidth needs high quality, high performance, low latency IP backbone multiple upstreams to commercial 2 large exchange points exclusive GEANT access 6
5 SWITCHlan is doing fine! IP service Gbps access speeds our No.1 service! OPN (optical private network) EoMPLS based P2P and multipoint links ( Gbps) resilient no bandwidth guarantee (but overprovisioning and careful monitoring) lambda services unprotected only so far exclusively used for LHCOPN CBF links sub-standard availability! CNAF - CERN CNAF - KIT CNAF - FERMILAB 7
6 Why fix what ain t broken?! SWITCHlan s DWDM gear is getting old some components face their end of life number of free lambdas decreasing rapidely investments no longer pay out no development to 40G/100G inflexible operations though less than 50% of lambdas are in use today! 8
7 Technology has gone a long way! 2012 sophisticated modulation schemes 2005 size tunable optics optical switching (ROADMs) Let us make best use of it! 9
8 Agenda! where we are today where we want to go how to get there fibers and optical transmission switching layer summary 10
9 What we anticipate! new users to be connected, mostly small ones continued average traffic growth of 40%, and sudden high bandwidth demands triggered by outplacement of storage & computing only few users will need full 100G any time soon 10G will prevail for the next years new trend: sensor sites at far away locations bandwidths needs exceeding GPRS, ADSL range but very limited budget often not permanent 11
10 Long Term Development Strategy optical layer forced upgrade all our DWDM infrastructure within 3 years (amplifiers, ROADMs, filters etc) a long term investment (for a 10 years life) additional channels and new functionalities deployed when needed select a vendor with a clearly defined, realistic road-map willingness for a continuing, close collaboration 13
11 Long Term Development Strategy network layer evolutionary approach continue to use existing (10G capable) routers new 100G capable router will be deployed as needed shorter renewal cycle compared to the optical equipment 14
12 Four things we want to improve! bandwidth reserves more lambdas 100Gbps capability flexibility transparent lambdas between all core nodes rapid channel setup auto-calibration of power levels stability topology improvements to enhance resilience optical switching capability at major junctions coverage enlarge fiber footprint extend core backbone over whole country 15
13 Agenda! where we are today where we want to go how to get there fibers and optical transmission switching layer summary 16
14 Overall network stability! based on 10 years experience we postulate three independent paths into hotspots Zürich, Geneva, Lugano two-way resilience on the core backbone single fiber paths sufficient within city limits stability of electric power worse than availability of fibers crucial: keep connectivity up even if a whole region goes black for a long time run two powerful exit points to the Internet build bypasses around major network hubs 17
15 Proposed fiber footprint 2015! moderate expansion of fiber footprint 19
16 Optical transport ! Sorrento DWDM lambdas CWDM router plugins + passive optics 1..4 lambdas BTI DWDM lambdas 20
17 The new optical core! equal capabilities for all regions uniform transmission gear to be built on existing fibers, while services remain up connects all cross border links to neighbor NRENs DFN BelWü extend core backbone Renater GARR 21
18 Photonic core backbone design! large university or computing center network hotspot smaller university numerous express lambdas between network hotspots large university or computing center typical span km max ring length 1000km most nodes add/drop few lambdas only express lambdas between network hotspots prevail minimizing OEO conversions seems reasonable thus we favor photonic ROADMs no bundling or sub-lambda switching on optical layer core nodes transponders 23
19 Key requirements! 40 lambdas, easily upgradable to 80 native 10G and 100G wavelengths 1000km reach without regeneration auto-calibration of optical power levels support for alien waves tolerance for optical signals outside C-band smooth path toward super-channels for 400G compatibility appreciated 24
20 Optical switching! optical switching capability mandatory initial deployment of multi-degree ROADMs at selected major fiber junctions at entry points of native lambda services long-term plans remain to be defined use of direction-, color-, contention-less ROADMs where and when? functionality versus reliability? economics, size, complexity? 25
21 About economics! equipment, connectivity dramatic increase in performance & functionality per $$ maintenance cost approx. stable fiber leases (CH) 45% of overall network cost find ways to mitigate! last 10 years: ~30% decrease in lease cost/m won t go significantly down any more 26
22 Fiber sharing with Hybrid WDM! Use existing backbone fibers to connect small sites! [nm] core backbone DWDM channels OSC spans up to 100km unrepeatered links up to 1000km regional links 4 CWDM channels links up to 60km L-Band range, suitable for amplified long range links for use by SWITCH to connect small sites by regional networks 27
23 Fiber sharing with Hybrid WDM! microhousing DWDM node HWDM splitter HWDM splitter HWDM splitter HWDM splitter DWDM node core site core site (routerless) small site possible for a few db more span loss micro-housing at regional junctions: cheap, small, passive 28
24 Agenda! where we are today where we want to go how to get there fibers and optical transmission switching layer summary 29
25 IP Layer Design Goals network services 99.99% availability overprovisioning -> virtually no packet loss lowest possible transfer delays IP service & private layer 2 networks network infrastructure meshed network two exit points at the extreme (Geneva & Zurich) PoPs at customer premises border of responsibility: Ethernet interface footprint & power is an issue must scale to small and big sites (1 : 100) 30
26 Routing vs. Switching shortest (physical) path first: IP routers shortest path bridging (TRILL, IEEE 802.1aq) test with TRILL (Brocade switches): missing network management tools lacking interoperability among vendors difficult to provide layer 2 services doesn t scale for a national network routed IP backbone robust, proven and well scalable solution small organizations connected with stub links (without router) 31
27 Layer 1 & 2 Services emulated layer 2 services benefit from meshed backbone topology EoMPLS point-to-point links, VPLS multipoint networks lambdas only for higher bandwidths, 10G and 100G protection will be available 32
28 MPLS in the Backbone layer 2 services forced us to deploy MPLS in the backbone the only available tunneling technology, that was implemented in hardware used for a restricted address range for layer 2 services only desirable solution: tunneling technique using encapsulation in IP no need for additional protocols in the backbone a use case for SDN? 33
29 Agenda! where we are today where we want to go how to get there fibers and optical transmission switching layer summary 34
30 Summary fiber footprint modest expansion transmission layer core backbone to cover all regions advanced, uniform DWDM system on core built to last 10 years coexists with other optical services on same fibers switching layer simple, robust, high performance routed IP network overprovisioning, no BoD private networks nevertheless needed traffic isolation no traffic engineering 35
