Task, Partecipazione, Programma e Richieste Finanziarie

Tiziana Ferrari, INFN-CNAFI Workshop INFN-GRID

Tiziana Ferrari

Work Package Task1. 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.

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.

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

– Experimental study

– traffic engineering

– VPN

– QoS

– INFN-GRID test bed, TF-NGN

8. WDM/dWDM
