Abstract
Significant technical progress in the computer science and networking, as
well as the rapid increase in users' requirements for computational
resources and diverse services, is leading to the gradual opening of Grid
computing, which is mainly a scientific- or business-oriented application,
to the consumer market. Such a scenario, often referred to as the consumer
Grid, is a major challenge because of the potentially large number of
dynamic resources and users (perhaps millions), high frequency of job
requests, and considerable heterogeneity in resource types in the consumer
market. These features will lead to several potential issues when consumer
Grid services are deployed with existing techniques. In this paper, we
analyze the limitations of current network infrastructures, resource
discovery and management schemes and end-to-end transmission control
protocols (TCP) that prevent the wide deployment of consumer Grid services.
Then, in order to address these issues, we propose an integrated optical
burst switching (OBS)/wavelength switched optical network (WSON)
infrastructure assisted by a self-organized resource discovery and
management scheme to support the consumer Grid. In addition, we review
several alternative TCP protocols and compare their performance in term of
throughput and fairness to select the most suitable TCP protocol for
end-to-end Grid data transmission. To the best of our knowledge, this is the
first time that these solutions have been proposed and investigated for the
consumer Grid, and more importantly, all the proposed methodologies are
demonstrated and evaluated on an actual OBS/WSON testbed with both control
and data planes, allowing the verification of their feasibility and
effectiveness, and obtaining valuable insights for deploying the proposed
solutions into real consumer Grid networks.
