How can we protect the network infrastructure from malicious traffic, such as scanning, malicious code propagation, and distributed denial-of-service (DDoS) attacks? One mechanism for blocking malicious traffic is filtering: access control lists (ACLs) can ...
We describe our design of a geocast service for mobile partitioned networks (MPNs). We focus mainly on minimizing the delivery latency. Our approach exploits the time-stability of the collective mobility pattern. In MPNs, in contrast to MANETs, the end-to- ...
Since the bandwidth-delay products of Internet links keep increasing, issues with TCP's convergence time, throughput, and amount of queuing in these environments are becoming more pressing. As we move toward the next-generation Internet, it is important to ...
We present an experimental study of crosstalk in a 1:40 multicasting architecture based on a one-pump modulated parametric amplifier. The optimal operating region is determined by an extensive sweep of pump and signal powers. ...
We report the first experimental demonstration of all-optical wavelength multicasting of OC-768 NRZ data using a pump modulated parametric amplifier. The performance of 40-fold multicasting with excellent signal integrity retention is described. ...
Wireless networking relies on a fundamental building block, neighbor discovery (ND). The nature of wireless communications, however, makes attacks against ND easy: An adversary can simply replay or relay (wormhole) packets across the network and mislead di ...
Query-response based protocols between a client and a server such as SSL, TLS, SSH are asymmetric in the sense that the querying client and the responding server play different roles, and for which there is a need for two-way linkability between queries an ...
This paper addresses the problem of streaming packetized media over a lossy packet network, with sender-driven (re)transmissions and receiver acknowledgments. It extends the markovian formulation of the rate- distortion optimized (RaDiO) streaming framewor ...
The need for nodes to be able to generate their own address and verify those from others, without relying on a global trusted authority, is a well-known problem in networking. One popular technique for solving this problem is to use self-certifying address ...

We report the experimental demonstration of all-optical
wavelength multicasting of OC-768 (40 Gbps) channel using
a single-pass, pump modulated parametric amplifier. The performances
of 1-to-20 and 1-to-40 multicasting with excellent signal fidelity
we ...
