In this position paper, we consider architectures of distributed interconnected clouds across geographically distributed, independently-administered storage and computation clusters. We consider two problems: federation of access across heterogeneous administrative domains, and computation jobs run over the wide area and heterogeneous data sets. We argue(More)
In this paper, we argue that federation of cloud systems requires a standard API for users to create, manage, and destroy virtual objects, and a standard naming scheme for virtual objects. We introduce an existing API for this purpose, the Slice-Based Federation Architecture, and demonstrate that it can be implemented on a number of existing cloud(More)
distributed service management, client-server systems, automated end-to-end diagnostics, model-based reasoning, MBR, network printing, artificial intelligence Modern applications increasingly depend on services that are distributed across the infrastructure, for example, printing, mail and database services. This is especially so in mobile computing, where(More)
—This work presents the Congestion Diversity Protocol (CDP), a routing algorithm for multi-hop wireless networks that ensures low end-to-end delay, high throughput, and fewer packet drops than existing routing protocols. In particular, CDP combines important aspects of shortest path routing and backpressure routing to achieve improved throughput and end-end(More)
The main objective of this thesis is to provide a framework for evaluating the cor-rectness of TCP implementations. We use this framework in order to assess the completeness and correctness of four widely available implementations: DEC OSF 3.2, FreeBSD 2.2.2, Windows 95 and Windows NT 4.0. Through our evaluation, we will attempt to determine which TCP(More)
