Networking in Italy Davide Salomoni The GARR Network GARR: Gruppo Armonizzazione Reti Ricerca (1988) Participants: Universities, INFN, CNR, other research institutes in Italy Non-profit organization Evolution: GARR-1 (TDM: DECnet IV/V, IP, SNA, X.25 - 1988) GARR-2 (mostly IP, max bandwidth 2Mbit/s - 1995) GARR-B (IP only, 34Mbit/s - 1998) GARR-B High-bandwidth infrastructure (34-155M) based on ATM VPs (CBR), with high-speed links to European research network and the Internet 15 PoP throughout Italy - the PoPs are in the Telecom premises, but the network is managed by the GARR consortium (practically speaking, at the moment, by INFN) User’s access to the network from 64K to 34M, w/ several technologies (ATM, Frame Relay, Leased lines) Sharing of a single physical 34M to a PoP between different users via ATM VP/VCs GARR-B Management INFN is (temporarily) managing the GARR-B network The GARR-B central management office is in Rome The GARR-B NOC is @ INFN/CNAF (Bologna) IP configuration and routing, HW/SW monitoring and troubleshooting, trouble tickets, interface to the GARR-B Access Port Managers, reports, Routing Registry, Internet Registry (LIR) • http://www.noc.garr.it (NOC) • http://www.garr.it/LIR (LIR) Planning of GARR-C Management of the international connections and participation to international committees TEN-155 and related research projects G7-GIBN (IT2) Network Management Public tools Traffic statistics Trouble Tickets The Looking Glass Traceroute Server Weather Maps Private tools Noc On Line (NOCOL) On-line Hardware Inventory Allocation of private AS Automated tools and robots for LIR and RR-related tasks Research Phased introduction of native multicasting into the network (PIM-SM with MBGP peering, connected to the existing DVMRP cloud) Planning and installation of other services directly connected to the PoPs news web caching QoS, in collaboration with European projects (TF-TANT) IntServ (RSVP) and mapping to ATM QoS DiffServ (IP Precedence and “true” DiffServ - see draft-ietfdiffserv-framework-02.txt) GARR-B Frankfurt NY Princeton (ESnet) The GARR-B backbone POP - Milano Princeton DE RC TEN-155 ESnet US (NY) RT POP - Roma RC RT RT RC POP - Bologna RT RC POP - Napoli Access to GARR-B User z GARR-B PoP RC RT User w ATM User x International or Domestic Peer User y A Transit PoP RC GARR-B PoP Fast Ethernet Ethernet GARR-B ATM RT Mgmt Router Physical Topology POP - Milano RC RT DE Princeton TEN-155 ESnet US (NY) POP - Roma POP - Bologna RC RC RT RT RC RT POP - Napoli IP Routing in GARR-B Milano-RT RouteReflector Napoli-RC RouteReflector Client Milano-RC RouteReflector Client Torino-RC RouteReflector Client Napoli-RT RouteReflector Bologna-RT RouteReflector Bologna-RC RouteReflector Client Routing protocols: •IBGP •OSPF Roma-RT RouteReflector Roma-RC RouteReflector Client Migration from GARR-2 Milano-RC ISP Milano-RT AS-CILEA NAP ISPs Napoli-RT Roma-RT AS-ROMA Routing Protocols: •IBGP •OSPF •EBGP Bologna-RT ISP Roma-RC NAP INROMA Bologna-RC AS-CINECA ISPs ISP Use of Private AS A) “remove-private-as” on RC RU AS-P1 RU AS-P1 sees 10.0.0.0 AS-137 AS-P3 sees 10.0.0.0 AS-137 ISP sees 10.0.0.0 AS-137 RT sees 10.0.0.0 AS-P2 10.0.0.0 AS-P2 RU RC AS-P3 AS-137 sends to AS-Px: ^$ AS-P1, AS-P3 get from AS-137: ^137$ AS-137 RT RT * B) “remove-private-as” on RT AS-P1 sees 10.0.0.0 AS-P2 AS-P3 sees 10.0.0.0 AS-P2 ISP sees 10.0.0.0 AS-137 RT sees 10.0.0.0 AS-P2 ISP AS-137 sends to AS-Px: ^$ and AS-Py AS-P1, AS-P3 get from AS-137: .* International Connectivity ATM link @155M to Frankfurt (TEN-155) separate VCs for US (New York) @45M -- access to “the Internet” (excluding ESnet!) Europe @100M -- access to TEN-155 and European peers T1 (1.5M) to Princeton -- used just to connect GARR to ESnet GARR-SLAC? Currently, using the 1.5M from GARR to Princeton -obviously not sufficient for BaBar Agreements permitting ($$$), it’s technically feasible (right now) to have direct access from GARR to ESnet @45M or more using e.g. an ATM VC; US endpoint? e.g. NY (ESnet PoP) SLAC? (dedicated link to BaBar) What are we to transfer via network to a regional center? DSTs? Size? Who extracts the DSTs (real-time?) from Objectivity? ESD+AOD+Tags? ~2.2MB/sec = 17.6Mbit/sec
