  2. INFN-CNAF networking (1) • Main network infrastructure based on optical fibres (~ 20 Km) • LAN has a “classical” star topology with 2 Core Switch/Router (ER16, BD) • Migration to Black Diamond 10808 with 180 GE and 12x10GE ports (it can scale up to 480 GE or 48x10GE) completed • CPU racks equipped with FE/GE switch (2xGbps optical uplinks to core switch) • Disk servers connected via GE to core switch (mainly fibre) • Some servers concentrated with copper cables to a dedicated switch • VLAN’s defined across switches (802.1q) • 43 rack switches (21 switches 10Gb ready): several brands, homogeneous characteristics • 48 Copper FEthernet ports (21 switches have all GEthernet ports) • Support of main standards (e.g. 802.1q) • 2 Gigabit up-links (optical fibers) to core switch • CNAF interconnected to GARR-G backbone at 1 Gbps + 10 Gbps for SC • Giga-PoP co-located • New access router (Cisco 7600 with 4x10GE and 4xGE interfaces) installed

  3. INFN-CNAF networking (2) • LAN connectivity ready for 10GE technology with capacity for 10 GE link aggregation • Data flows will land on disk buffer system • possibly CASTOR, but also other SRM systems (StorRM and dCache) under evaluation • 1 network prefix for LHCOPN (131.154.128/17) • 1 additional prefix for SC (192.135.23/24) • Security model will be based on L3 filters (ACLs) within the L3 equipment • On BD • Monitoring via snmp (presently v2) • mrtg, nagios
