A file location, replication, and distribution system for network information to aid network management

Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2010.Cataloged from PDF version of thesis.Includes bibliographical references (p. 103-105).This thesis demonstrates and evaluates the design, architecture, and implementation of a file location, replication, and distribution system built with the objective of managing information in an Internet network. The system's goal is to enable the availability of information by providing alternative locations for files in case of situations where the original piece of information cannot be found in the network due to failures or other problems. The system provides the mechanism for duplicating files and executes the act of placing them in multiple locations according to predefined rules for distribution. The resulting system is a working model for a file management system that can exist over the Internet and will aid in overall network management by organizing and overseeing the information found within a network.by Tiffany Cheng.M.Eng

A region-based architecture for service-providing distributed systems

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2005.Includes bibliographical references (leaves 131-136).A service-providing system consists of hosts that provide services such as data, content, computational and memory resources and data-based services to other entities in the system. Consumers that wish to use services describe their needs with a set of high-level objectives. In this thesis, we address the problem of locating services in a large-scale distributed system using their descriptions, rather than their addresses. We propose a network architecture that is based on the concept of dividing the service-providing hosts into Regions. A Region is a grouping of elements of the network that share a set of common characteristics and policies. Members of a region manage their interactions with other regions and their elements according to some defined rules and policies. Hosts can be divided into regions based on various properties such as their content, their commercial model or their security characteristics to name a few. The service provided by a region is an aggregate of the services provided by all its member hosts. The region-based architecture routes a service request through the network efficiently based on its description and on the advertisements from regions providing services. Division of hosts into a set of independent regions partitions the search space and produces a scalable structure.(cont.) The architecture also does not impose any rules on the internal organization of regions making the system flexible and dynamic.by Neha Singh.S.M
