Widely used protocols (UDP and TCP) are observed for variations of the UDP to TCP ratio and of port number distribution, both over time and between different networks. The purpose of the study was to understand the impact of application trends, especially the growth in media streaming, on traffic characteristics. The results showed substantial variability but little sign of a systematic trend over...
This paper proposes a measurement metric to observe and analyze traffic variations at the higher abstraction level, i.e., IP host and its interactions. Each interaction is extracted for three common attributes: number of flows, size in bytes and lifetime. Applying the coefficient of variation metric for the interactions (flow, size, lifetime) of each host, our analysis shows that although many hosts...
In modern passive network measurement, flow-based analyses have been widely used. In this paper, we regard dasiahostspsila as aggregations of flows, and investigate host rather than flow-based measurements. We show that analyzing host behaviors contribute significantly to better understanding of network behavior, thus it is a feasible study that should be of interest to both researchers and network...
Much work has been done on observing and determining application types for network traffic flows. This is non-trivial because newer applications often encrypt their packets and do not use default port numbers. Also, application updates or protocol changes could vary the distributions of flow behaviors and patterns, resulting in complicated identification methods. We propose a different approach, in...
