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)
In a lysogen, most genes of phage lambda are repressed; in response to a transient induction signal, they are efficiently switched on. The switch, which consists in part of a tripartite operator to which two regulatory proteins bind, depends not only on DNA--protein interactions, but also on effects transmitted from one DNA-bound protein to another. lambda(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)
In this paper we describe a method for constructing E. coli plasmids that direct efficient expression of genes that encode eucaryotic or procaryotic proteins. No functional assays for the proteins are needed, and they are produced in their native, unfused state. The only requirement is that the genes be isolable without intervening sequences. We describe as(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)
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)
