2 The network topology is a hub and spoke structure Central routing solution The central routing solution is used to provide the functions of the customer CPE routers, using logical router features The goal is to have a 10 to 15 year lifetime of the fiber system (including amplifiers etc.) and a 5 to 8 year lifetime of the attached electronics (routers etc.)

3 SUNET has signed a contract for a 8 to 12 years lease of dark fiber from TDC Song, which is becoming our only supplier of fiber for the whole network Using several subcontractors. Some details: Wide area network between PoPs km of dark fiber, in 46 sections Local loops from PoPs to universities 94 dark fiber connections 3 x 2,5 Gbit/s connections (due to cost constraints) 2 x Visby, 1 x Kiruna

4 3 systems North North, West and South 2 networks per system Red and Green West Redundancy on layer 3 Special solutions: Kiruna ( Blue network ) South One optical system (capable of 10 Gbit/s) + leased OC48 Visby 2 * leased OC48.

5 Different customer (university) types: Type A: Large university 2 * 10GE as access, with possibility for p2p lambdas. Type B: Smaller university 2 * GE as access. Will keep their Cisco 10720s Type C: Kiruna (due to technical reasons) One optical path (as for type A), with leased 2,5G lambda as backup. Type D: Visby (due to technical reasons) Two leased 2,5G lambdas. Will keep the Cisco 10720s.

6 Preferably no regeneration on 10G network. 40G capable Transparent traversal (not using transponders) between the different networks. LDGE Low Density Gigabit Ethernet Possibility to provide GE connections everywhere p2p capabilities 40G (later), 10GE, 2.5G, 1GE and possibly FC.

7 # Central routing solution Using logical routers as CPE :s Lower CAPEX Lower OPEX Easier capacity planning / better utilization of equipment. Simple 10-to-one converters at university premises (for type A customers) Continue to use our Cisco 10720s for type B customers. "

Day one, there will be 1 slot with a DWDM card for connection to the CN4200, 1 slot for 10 GE to the redundant Also 1 slot for the 10 GE and 1 slot for the 8 port 1 GE connection for customer LAN equipment.

25 9,. /&.(3 I grundläget behöver ni inte skaffa ny lokal utrustning. Använd logisk router i centrala klustret och CN4350 som 10:1 konverter (dvs. anslut er lokala utrustning med n*ge). Om ni har lokal utrustning som är kapabel till 10 Gbit/sek, men inte kan köra full BGP: Använd logisk router i centrala klustret och kör 10 Gbit/sek till er egen utrustning från CN4350. Om ni har lokal utrustning som kan 10 Gbit/sek och full BGP: Använd den (logisk router behövs inte). Migrering mellan dessa varianter är möjlig.

26 9,. /&.(3 Har man logisk router i det centrala klustret så får man SUNET-rötter + defaultroute från AS1653. Om man har egen, fullt BGP-kapabel, accessrouter kan man även välja full BGPtabell om man vill. Eventuella specialfall hanteras separat/senare.
