Algorithmic Principles for Building Efficient Overlay Computers

Aeolus Project

The recent explosive growth of the Internet gives rise to the possibility of a global computer of grand-scale consisting of Internet-connected computing entities (possibly mobile, with varying computational capabilities, connected among them with different communication media), globally available and able to provide to its users a rich menu of high-level integrated services that make use of its aggregated computational power, storage space, and information resources. Achieving this efficiently and transparently is a major challenge that can be overcome by introducing an intermediate layer, the overlay computer. The goal of this project is to investigate the principles and develop the algorithmic methods for building such an overlay computer that enables this efficient and transparent access to the resources of an Internet-based global computer. In particular, the main objectives of this project are:

  • To identify and study the important fundamental problems and investigate the corresponding algorithmic principles related to overlay computers running on global computers
  • To identify the important functionalities such an overlay computer should provide as tools to the programmer, and to develop, rigorously analyze and experimentally validate algorithmic methods that can make these functionalities efficient, scalable, fault-tolerant, and transparent to heterogeneity
  • To provide improved methods for communication and computing among wireless and possibly mobile nodes so that they can transparently become part of larger Internetbased overlay computers
  • To implement a set of functionalities, integrate them under a common software platform in order to provide the basic primitives of an overlay computer, as well as build sample services on this overlay computer, thus providing a proof-of-concept for our theoretical results
