TL;DR: The case for extending the tenant-provider interface to explicitly account for the network is made, and the design of virtual network abstractions that capture the trade-off between the performance guarantees offered to tenants, their costs and the provider revenue are proposed.

TL;DR: SocialCast is proposed, a routing framework for publish-subscribe that exploits predictions based on metrics of social interaction to identify the best information carriers and shows that prediction of colocation and node mobility allow for maintaining a very high and steady event delivery with low overhead and latency.

TL;DR: This paper designs an extended routing service allowing easy implementation of application-specific routing protocols on CamCube, and demonstrates the benefits and network-level impact of running multiple routing protocols.

TL;DR: Camdoop, a MapReduce-like system running on CamCube, a cluster design that uses a direct-connect network topology with servers directly linked to other servers, is built and demonstrated that it significantly reduces the network traffic and provides high performance increase over a version of Camdoop running over a switch and against two production systems, Hadoop and Dryad/DryadLINQ.

TL;DR: This paper separates orthogonal areas of middleware functionality into self-contained components that can be selectively and individually deployed according to current resource constraints and application needs and can be updated at runtime to provide the basis of a highly dynamic and reconfigurable system.
