We expose an unorthodox adversarial attack that exploits the transients of a system's adaptive behavior, as opposed to its limited steady-state capacity. We show that a well orchestrated attack could introduce significant inefficiencies that could potentially deprive a network element from much of its capacity, or significantly reduce its service quality,(More)
— Current computing systems depend on adaptation mechanisms to ensure that they remain in quiescent operating regions. These regions are often defined using efficiency, fairness, and stability properties. To that end, traditional research works in scalable server architectures and protocols have focused on promoting these properties by proposing even more(More)
With the increased use of "Virtual Machines" (VMs) as vehicles that isolate applications running on the same host, it is necessary to devise techniques that enable multiple VMs to share underlying resources both fairly and efficiently. To that end, one common approach is to deploy complex resource management techniques in the hosting infrastructure.(More)
—One key adaptation mechanism often deployed in networking and computing systems is dynamic load balancing. The goal from employing dynamic load balancers is to ensure that the offered load would be judiciously distributed across resources to optimize the overall performance. To that end, this paper discovers and studies new instances of Reduction of(More)
The best-effort nature of the Internet poses a significant obstacle to the deployment of many applications that require guaranteed bandwidth. In this paper, we present a novel approach that enables two edge/border routers— which we call Internet Traffic Managers (ITM)—to use an adaptive number of TCP connections to set up a tunnel of desirable bandwidth(More)
— The proliferation of mobile devices, coupled by the increase in their capabilities, have enabled the establishment of a rich mobile computing platform for various applications. In this paper we propose a probabilistic code distribution model that enables a mobile device to execute code segments through the help of nearby mobile devices in a secure and(More)
Internet Traffic Managers (ITMs) are special machines placed at strategic places in the Internet. itmBench is an interface that allows users (e.g. network managers, service providers, or experimental researchers) to register different traffic control functionalities to run on one ITM or an overlay of ITMs. Thus itmBench offers a tool that is extensible and(More)
Internet end-systems employ various adaptation mechanisms that enable them to respond adequately to legitimate requests in overload situations. Today, these mechanisms are incorporated in most scalable end-systems through the use of one or more component subsystems such as admission controllers, traffic shapers, content transcoders, QoS Controllers, and(More)
