Middleboxes play a major role in contemporary networks, as forwarding packets is often not enough to meet operator demands, and other functionalities (such as security, QoS/QoE provisioning, and load balancing) are required.
It's often believed that multipath routing is always beneficial. Taking a traffic engineering perspective, we consider commonly used goals such as congestion minimization, minimum average delay, and minimum cost routing.
J. K. Aggarwal is on the faculty of The University of Texas at Austin College of Engineering and is currently a Cullen Professor of Electrical and Computer Engineering and Director of the Computer and Vision Research Center.
Traffic Engineering is of fundamental importance for network operation. Traditionally, it assumes static traffic input and then looks for distributed routing solutions to optimize certain objective.
Click-fraud in online advertising siphons several tens of millions of dollars from the online advertising ecosystem. In this talk, I'll talk about our in-depth investigations into one of the most common ways of committing online advertising click-fraud.

Fathers of the Internet reflecting on the evolution of the Internet (and a celebration of the 40th anniversary of the invention of TCP/IP protocol for the Internet by Cerf & Kahn in 1974.)
Modern network software is implemented across two tiers: the data plane, which contains packet-processing rules implemented efficiently on switching hardware, and the control plane, which implements fundamental algorithms, policies, and business rules that determine what the data plane should do.
Signature-based detection is one of the fundamental technique to detect malicious activities in a network environment. Today, the performance of the security tools is dominated by the speed of the string-matching algorithms that detect these signatures.
