1 Tiziana Ferrari Work package 5 – Network Task, Partecipazione, Programma e Richieste Finanziarie Tiziana Ferrari, INFN-CNAF I Workshop INFN-GRID

2 Tiziana Ferrari Work Package Task 1.LAN/fabric networking. –Evaluation of networking issues related to the fabric architectures under analysis in WP2. 2.FTP –Study of standardization status of the ftp protocol at IETF; –Experimental evaluation of prototypes of the grid ftp, i.e. of different implementations of the extended ftp protocol under definition at the Grid Forum: e.g. gsiftp (Globus), NCftp (NASA) and Washington University ftp; –Contribution to the definition of the extensions of the ftp protocol in collaboration with the Grid Forum; evaluation of the possibility to extend the protocol definition for the support of file transfer in a multicast scenarios through reliable multicast.

3 Tiziana Ferrari Work Package Task (cont) 3.Reliable Multicast –Study of state of the art of reliable multicast for the evaluation of the maturity of this architecture currently under study at IRTF; –Evaluation of the applicability of reliable multicast to replica management (sub-task to be developed in collaboration with WP2 of Data Grid) and for information exchange GRIS GIIS –Experimentation of reliable multicast-based ftp prototypes; –Study of applicability of multicast extensions to ftp in the framework of the Grid Forum. 4.IBP –Evaluation of networking issues related to the IBP protocol; –Evaluation of IBP data server distribution in the wide area.

4 Tiziana Ferrari Work Package Task (cont) 5.Client-server connection methodologies –Network = operazione di I/O all'interno di un sistema operativo (MPI, database distribuiti, DFS, AFS.....); estensibilita del sistema operativo alla rete; –Network = interconnessione di server e client (server FTPS, WEB,...); modelli client/server, interfacce e protocolli. 6.Traffic Monitoring at network and application level - to be applied to Testbed 0 and following releases; adaptation/refinement of an existing monitoring tools

5 Tiziana Ferrari Work Package Task (cont) 7.MPLS –Experimental study –traffic engineering –VPN –QoS –INFN-GRID test bed, TF-NGN 8.WDM/dWDM –Technology tracking –LAN and WAN (TF-NGN)
