Highlights

CASPER

This collaborative research effort, dubbed Coupled Air-Sea Processes and EM Ducting Research (CASPER) addresses overarching knowledge gaps related to electromagnetic (EM) wave propagation in coastal Marine Atmospheric Boundary Layers (MABL). The objective is to fully characterize the MABL as an EM propagation environment.

Hybrid schemes for exact conditional inference in discrete exponential families

Exact conditional goodness-of-fit tests for discrete exponential family models can be conducted via Monte Carlo estimation of p values by sampling from the conditional distribution of multiway contingency tables. The proposed method runs many parallel chains initialized at SIS samples across the fiber. The scheme alleviates many of the challenges faced by the MCMC and SIS schemes individually while largely retaining their strengths. It also provides diagnostics that guide and lend credibility to the procedure. Simulations demonstrate the viability of the approach.

A Distributed Platform for High-Speed Active Network Topology Discovery

Rohrer, Justin P.

Prior collaborative work with LTS has produced a novel high-speed active network mapping tool, 鈥淵arrp鈥� (Yelling at Random Routers Progressively). Yarrp is unique in that it is stateless and randomly permutes the order of its probing, thereby providing a means to perform Internet-scale traceroute style network discovery. While relatively small Yarrp runs have been performed on the live Internet and demonstrated Yarrp's ability to operate an order of magnitude faster than competing approaches, the focus of this proposal is to enhance Yarrp so that it can run continually in a production environment to provide a near real-time view of the network topology. As such, we propose the following primary research thrusts:

1) Further increase Yarrp's speed

2) Evaluate potential commercial platforms for Yarrp deployment

3) Develop distributed Yarrp

4) Use Yarrp to map the IPv6 Internet

These thrusts are intertwined, but each is crucial to the eventual production deployment of Yarrp. For instance, to achieve the necessary mapping speed, we will both optimize and distribute Yarrp. And, deployment on existing commercial cloud platforms will require the special probe header encoding in Yarrp to be robust to real-world NATs and security appliances. The end result of our proposed effort is a distributed version of Yarrp that map the IP-level data-plane path to every /24 prefix in the IPv4 Internet in less than an hour.
