We present decoy routing, a mechanism capable of circumventing common network filtering strategies. Unlike other circumvention techniques, decoy routing does not require a client to connect to a specific IP address (which is easily blocked) in order to provide circumvention. We show that if it is possible for a client to connect to any unblocked(More)
We address the problem of privacy in publish-subscribe(pub-sub) systems that typically expose some form of published content and subscriber interest, at least to the infrastructure responsible for subscription matching and content delivery. In our recent work, we proposed P3S, a pub-sub middleware designed to protect the privacy of subscriber interest and(More)
We present a content network architecture for a cluster of satellites flying in low Earth orbit. The cluster uses a dynamic wireless network to interconnect the satellites and has an intermittent link to the ground. Even though a cluster of satellites fly in formation, their relative positions can vary widely, and occasionally the cluster can disperse and(More)
Disadvantaged wireless communications, such as those in fractionated spacecraft systems, need real-time, reliable, and fault tolerant information dissemination from information producers (such as sensors) to information consumers (such as information exploitation, analysis, or command and control systems). Such systems are well-suited to the(More)
— Although IP and its overlying protocols, such as TCP and UDP, are ubiquitous, they were originally designed for point-to-point connections between computers in reasonably fixed locations. They are less suited to mobile networks and broadcast communications. In this paper, we present an alternative to IP that is based on a publish-subscribe approach. The(More)
As software defined networks (SDN) grow in size and in number, the problem of coordinating the actions of multiple SDN controllers will grow in importance. In this paper, we propose a way of organizing SDN control based on coordinated <i>subgraph shadowing</i>. Graphs are a natural way to think about and describe SDN activity. Subgraphs provide a means to(More)
