Experimental Study of Remote Job Submission and Execution on LRM Through Grid Computing Mechanisms
Experimental Study of Remote Job Submission and Execution on LRM through Grid Computing Mechanisms Harshadkumar B. Prajapati Vipul A. Shah Information Technology Department Instrumentation & Control Engineering Dharmsinh Desai University Department Nadiad, INDIA Dharmsinh Desai University e-mail: [email protected], Nadiad, INDIA [email protected] e-mail: [email protected], [email protected] Abstract —Remote job submission and execution is The fundamental unit of work-done in Grid fundamental requirement of distributed computing done computing is successful execution of a job. A job in using Cluster computing. However, Cluster computing Grid is generally a batch-job, which does not interact limits usage within a single organization. Grid computing with user while it is running. Higher-level Grid environment can allow use of resources for remote job services and applications use job submission and execution that are available in other organizations. This execution facilities that are supported by a Grid paper discusses concepts of batch-job execution using LRM and using Grid. The paper discusses two ways of middleware. Therefore, it is very important to preparing test Grid computing environment that we use understand how a job is submitted, executed, and for experimental testing of concepts. This paper presents monitored in Grid computing environment. experimental testing of remote job submission and Researchers and scientists who are working in higher- execution mechanisms through LRM specific way and level Grid services and applications do not pay much Grid computing ways. Moreover, the paper also discusses attention to the underlying Grid infrastructure in their various problems faced while working with Grid published work. -

IP Flow Mobility Support for Proxy Mobile Ipv6 Based Networks
UNIVERSIT A` DEGLI STUDI DI PADOVA Facolt`adi Ingegneria Corso di Laurea in Ingegneria delle Telecomunicazioni Tesi di Laurea IP Flow Mobility support for Proxy Mobile IPv6 based networks Relatori: Prof. Michele Zorzi Dott. Telemaco Melia Candidato: Fabio Giust Anno accademico 2010-2011 Summary The ability of offloading selected IP data traffic from 3G to WLAN access networks is considered a key feature in the upcoming 3GPP specifications, being the main goal to alleviate data congestion in cellular networks while delivering a positive user experience. Lately, the 3GPP has adopted solutions that enable mobility of IP-based wireless devices relocating mobility functions from the terminal to the network. To this end, the IETF has standardized Proxy Mobile IPv6 (PMIPv6), a protocol capable to hide often complex mobility procedures from the mobile devices. This thesis, in line with the mentioned offload requirement, further extends PMI- Pv6 to support dynamic IP flow mobility management across access wireless net- works according to operator policies. In this work, we assess the feasibility of the proposed solution and provide an experimental analysis based on a prototype net- work setup, implementing the PMIPv6 protocol and the related enhancements for flow mobility support. La capacit`adi spostare flussi IP da una rete di accesso 3G ad una di tipo WLAN `econsiderata una caratteristica chiave nelle specifiche future di 3GPP, essendo il principale metodo per alleviare la congestione nelle reti cellulari mantenendo al contempo una ragionevole qualit`apercepita dall’utente. Recentemente, 3GPP ha adottato soluzioni di mobilit`aper dispositivi con accesso radio basato su IP, tra- slando le funzioni di supporto dal terminale alla rete, e, a questo scopo, IETF ha standardizzato Proxy Mobile IPv6 (PMIPv6), un protocollo studiato per nascondere le procedure di mobilit`aai sistemi mobili.
