“…The purpose of the measurements was to build models of IP traffic and user behaviour, see e.g. [3] [4]. Data from the application to the packet level per household were collected in real networks located in different countries (Sweden and Spain) covering different types of access (FTTH, xDSL, CMTS, cellular, university network).…”

In this paper, we discuss research problems for enabling content distribution and supporting real-time interpersonal communication services (e.g. voice and video) over best effort networks with sufficient quality. We take a practical view of content distribution and quality, and this is the reason for the term "sufficient". We argue that the understanding of quality as perceived by the user is a key factor in this context, but also that the understanding of context dependence is a key factor for delivering services which are "good enough" to make the user satisfied. We base our assumptions upon results from the Celtic TRAMMS project, and we describe how to leverage upon the framework for traffic measurements that was built up in that project. Moreover, we identify key technological components that are common for optimization of content delivery and real-time interpersonal communication services such as VoIP and videoconferencing. We also describe how the research problems stated will be tackled in the newly started IPNQSIS project.

Towards a user network profiling for internal security using top-k rankings similarity measures. Abstract-A major goal of current computer network security systems is to protect the network from outside attackers; however, protecting the network from its own users is still an unattended problem. In campus area networks, the risk of having internal attacks is high because of their topologies and the amount of users. This work proposes a new approach to identify whether a network user is having or not a normal behavior, by analyzing host traffic using top-k ranking similarity measures. The result of this analysis could be an input of intrusion detection systems. The document presents an experiment where real-time traffic of different users in a campus area network is compared to a reference traffic that corresponds to one of them.

“…Activity of network users is considered through defining the activity factor, f a , which shows how many users are active in average at each particular point of time of the day. The activity factors are based on statistical data and measurements [28,29,30] and follow a sinusoidal-like curve with a maximum in the afternoon hours between 6 pm and 9 pm and a minimum in the early morning hours as shown in Figure 9 . In order to take into account future changes of user behavior and developments in network technologies, we assume here three activity factors and four average data rates.…”

“…The average access data rates that we assume for users of wireless and wired networks are shown in Table 5. DR 1 represents the average data rate per active user in current access networks [30,31], while DR 2 , DR 3 and DR 4 are projected data rates for the years 2014, 2016 and 2020 [31]. The ratio between downstream/upstream data rates is set to 3/2.…”

Energy efficiency of femtocell deployment in combined wireless/optical access networks

et al. 2013

Optical/wireless convergence has become of particular interest recently because a combined radio wireless and optical wired network has the potential to provide both mobility and high bandwidth in an efficient way. Recent developments of new radio access technologies such as the Long Term Evolution (LTE) and introduction of femtocell base stations open new perspectives in providing broadband services and applications to everyone and everywhere, but the instantaneous quality of radio channel varies in time, space and frequency and radio communication is inherently energy inefficient and susceptible to reflections and interference. On the other hand, optical fiber-based networks do not provide mobility, but they are robust, energy efficient, and able to provide both an almost unlimited bandwidth and high availability.In this paper, we analyze the energy efficiency of combined wireless/optical access networks, in which LTE technology provides ubiquitous broadband Internet access, while optical fiber-based technologies serve as wireless backhaul and offer high-bandwidth wired Internet access to business and residential customers. In this contest, we pay a particular attention to femtocell deployment for increasing both access data rates and area coverage. The paper presents a novel model for evaluating the energy efficiency of combined optical/wireless networks that takes into account the main architectural and implementational aspects of both RF wireless and optical parts of the access network. Several hypothetical network deployment scenarios are defined and used to study effects of femtocell deployment and power saving techniques on network's energy efficiency in urban, suburban and rural areas and for different traffic conditions.
