“…For the failures-prone scenario, we aimed to investigate how well various task admission and selection strategies would perform in the face of large failures, such as distributed denial of service attacks and power outages, which cause entire provider sites to fail. We selected such scenarios because power outages and denial of service attacks are increasing threats [20,21]. For the failures-prone scenario, we repeated the conditions of the heterogeneous scenario but introduced the possibility that providers could fail and then recover.…”

Can Economics-based Resource Allocation Prove Effective in a Computation Marketplace?

Several companies offer computation on demand for a fee. More companies are expected to enter this business over the next decade, leading to a marketplace for computation resources. Resources will be allocated through economic mechanisms that establish the relative values of providers and customers. Society at large should benefit from discoveries obtained through the vast computing power that will become available. Given such a computation marketplace, can economics-based resource allocation provide benefits for providers, customers and society? To investigate this question, we simulate a Grid economy where individual providers and customers pursue their own ends and we measure resulting effects on system welfare. In our experiments, customers attempt to maximize their individual utilities, while providers pursue strategies chosen from three classes: information-free, utilization-based and economicsbased. We find that, during periods of excess demand, economics-based strategies yield overall resource allocation that benefits system welfare. Further, economics-based strategies respond well to sudden overloads caused by temporary provider failures. During periods of moderate demand, we find that economics-based strategies provide ample system welfare, comparable with that of utilization-based strategies. We also identify and discuss key factors that arise when using economic mechanisms to allocate resources in a computation marketplace.

“…Fourth, we investigate market robustness in the face of sudden, temporary failures among providers. Such failures may arise in computation marketplaces due to problems in the power distribution grid [20] or to attacks on selected provider sites [21].…”

“…DoS may occur due to high demand of authentic users (e.g., congestion and flash crowd) or an unmalicious fault (e.g., network outage) or it may occur due to malicious actions carried out by unauthentic users on the network, which is a DoS attack (e.g., SYN flooding) [1]. DoS attacks can be executed in two ways.…”

In cyberspace, availability of the resources is the key component of cyber security along with confidentiality and integrity. Distributed Denial of Service (DDoS) attack has become one of the major threats to the availability of resources in computer networks. It is a challenging problem in the Internet. In this paper, we present a detailed study of DDoS attacks on the Internet specifically the attacks due to protocols vulnerabilities in the TCP/IP model, their countermeasures and various DDoS attack mechanisms. We thoroughly review DDoS attacks defense and analyze the strengths and weaknesses of different proposed mechanisms.
