- Dynamic Load Balancing Without Packet Reordering
- Dynamic load balancing is a popular recent technique that protects ISP networks from sudden congestion caused by load spikes or link failures. Dynamic load balancing protocols, however, require schemes for splitting traffic across multiple paths at a fine granularity. Current splitting schemes present a tussle between slicing granularity and packet...

- Network Monitoring Using Traffic Dispersion Graphs (TDGs)
- Monitoring network traffic and detecting unwanted applications has become a challenging problem, since many applications obfuscate their traffic using unregistered port numbers or payload encryption. Apart from some notable exceptions, most traffic monitoring tools use two types of approaches: keeping traffic statistics such as packet sizes and inter-arrivals, flow counts,...
