In today's Internet scenario, the current TCP has performed reasonably well. As the Internet has scaled up in load, speed, size and connectivity by the order of six over the past fifteen years, the TCP has consistently avoided severe congestion throughout this same period. Applications involving high performance computings such as bulk-data transfer, multimedia Web streaming, and computational grids demand high bandwidth. These applications usually operate over wide-area networks and, hence, performance over wide-area networks has become a critical issue. Future applications will need steady transfer rates in the order of gigabits per second to support collaborative work. TCP, which is the most widely used protocol, is expected to be used in these scenarios. It has been shown that TCP doesn't work well in this new environment, and several new TCP versions have been developed in recent years to address this issue. To date, there has not been a performance evaluation of various TCP protocols. In this thesis, various TCP versions 3/4 Tahoe, Reno, Newreno, Vegas, Westwood, Sack, Highspeed TCP, Scalable TCP 3/4 have been evaluated for their performance over high bandwidth delay product networks. It was found that the flow and congestion control mechanism used in TCP was unable to reach full utilization on high-speed links. Also discussed in this Thesis are fairness issues related to these new protocols with respect to themselves and with others.

Magíster en Minería / Existe suficiente evidencia que asegura que las tronaduras de incorporación de área en roca primaria generan sismicidad inducida, éstas elevan los niveles de peligro sísmico en sistemas de caving, como es el caso de la mina El Teniente, Codelco. El control integral del peligro sísmico resulta fundamental no sólo desde el punto de vista económico, sino también de la amenaza que representa sobre la integridad física de los trabajadores e instalaciones. Es importante analizar la sismicidad e incluso configurar modelos causa-efecto que permitan estimar confiablemente la probabilidad de generar sismos de magnitud relevante (momento magnitud mayor igual a 0,7) luego de una tronadura en la mina Reservas Norte (RENO). Con el uso de modelos analíticos, es posible conocer el periodo de reingreso necesario cuando el sistema se encuentra en alerta sísmica. Por otra parte, mediante la utilización de regresión logística, es factible conocer qué variables geológicas y mineras son las más relevantes en la caracterización del sistema e influencian el aumento del peligro sísmico. Los resultados del presente estudio indican que la aplicación de estos modelos analíticos, entregan una alternativa adecuada para estimar periodos de aislación y proponer un espacio-tiempo óptimo de análisis de secuencias sísmicas. Con esto, es posible ajustar modelos causa-efecto, cuya utilización genera una utilidad económica considerable, cuando el tiempo real de aislación es cercano a 8 horas (utilizado comúnmente en RENO). Por otro lado, las variables geológicas y mineras más importantes en la estimación del peligro sísmico, son las estructuras geológicas principales y el área incorporada o tamaño de la tronadura. En definitiva, este trabajo permitió ajustar distintos modelos con un alto desempeño, cada uno con diferentes características y aplicabilidad dependiendo del usuario.

Mobile Ad hoc network routing protocols have been divided in several different categories such as Reactive and Proactive Routing Protocol. The performances of these categories are evaluated in different scenario with TCP variants. We present a comprehensive TCP performance evaluation study to understand the nature of the TCP performance in different scenarios with variable amount of payload and number of nodes. The traffic consists of three different packet sizes i.e. 512, 1000, 1500 bytes each. Three different routing protocols (AODV, DSR and TORA) are to be evaluated with three different TCP variants (Tahoe, Reno and New Reno) in three different scenarios having 3, 5 and 8 nodes. The performances parameters on the basis of which routing protocols are to be graded are mainly throughput, congestion window and delay. Conclusions are drawn based on the simulation results and the comparisons between them have been elaborated. / N.W.F.P PAKISTAN. Mobile no: 0092-3339173438

This study provides a genre analysis of Janet Reno's apologia in response to the Mt. Carmel disaster. Discussions of the events leading up to the crisis, Reno's rhetorical response, and relevant situational constraints and exigencies are provided.
