Characteristics of flow describe the pattern and trend of network traffic, it helps network operator understanding network usage and user behavior, especially useful for those who concerns more about network capacity planning, traffic engineering and fault handling. Due to the large scale of datacenter network and explosive growth of traffic volume, it's hard to collect, store and analyze Internet...
A probabilistic password model assigns a probability value to each string. Such models are useful for research into understanding what makes users choose more (or less) secure passwords, and for constructing password strength meters and password cracking utilities. Guess number graphs generated from password models are a widely used method in password research. In this paper, we show that probability-threshold...
In Delay Tolerant Networks (DTNs), characteristics of mobility model have essential impact on routing protocols design and verification. Most of current studies about network characteristics are derived from theoretical models or small-scale real network traces. Properties of nodes in those networks are simple and can not reflect features in large-scale applications. In addition, few studies focus...
Bus Net is a kind of wireless network which is consist of buses and bus stations. It has the following features: 1) no end-to-end connection between source and destination, 2) intermittent connectivity, 3) high end-to-end delays. However, unlike the other DTNs, the node's mobility in Bus Net is semi-deterministic, which means the node's line is determined but the arriving time is undetermined. With...
Services Computing has become an increasingly important area in the IT and business sectors. In particular, Services now account for more than half of the economy in the United States and other countries. Numerous Services Computing-related degree programs and accreditation processes are being created. However, very few systematic guidelines exist for building graduate programs for Services Computing...
