  1. INFN GRID WP 5: NETWORK Areas : • LAN Technologies • Data Transport Protocols for an efficient utilization of the network • resources • Quality of Service • Application characterization • QoS implementation • Dynamic network configuration • New communication technologies • WDM • DWDM • Multiprotocol lambda switching INFN-GRID Work Package 5 - NETWORK

  2. Framework: • activities shared with DATAGRID WP Network • collaboration with INFN GRID Computing Fabric WP and Testbed WP • dedicated experimental network set-up, in collaboration with GARR-G Goal: • definition of guidelines for the engineering of a network architecture suitable for the GRID environment • topology (LAN and WAN) • transport protocols • transmission technology INFN-GRID Work Package 5 - NETWORK

  3. 1) LAN Technologies CONTENT: a) topology, transmission tehcnologies and connectivity to the WAN for the implementation of the LAN and of the Computing Fabirc SAN, NAS, ... b) Transport protocols for conputing clusters: GAMMA, ... In collaboration with the computing fabric WP INFN-GRID Work Package 5 - NETWORK

  4. 2) Data Transport Protocols • CONTENT: • Evaluation/tuning of exisiting transport protocols • RTT-related issues, mechanisms for congestion control • Performance of existing data transfert protocols • Nexus (GLOBUS) • Group communication protocols (consistency of replicated databases) • Distributed Object protocols: CORBA/IIOP • Internet backplane protocol • Scalable reliable multicast • ...
