It is a matter of fact that the Quality of Experience (QoE) has become one of the key factors that determine whether a new multimedia service will be successfully accepted by the final users. Accordingly, several QoE models have been developed with the aim of capturing the perception of the user by considering as many influencing factors as possibl...

Question
Dear All,
I am trying to add an interface in the mininet topology through Ryu controller however being a beginner, I am not sure how can I do it. 
Description of what I want to do:  Consider this linear topology
h1----s1----s2----h2
In this topology, I would like to make a connection of h2 to s1 so that the traffic from h1 to h2 doesn't go through s2.
What I have found till now is I can use, class OVSBridge(object) which can be found here https://github.com/osrg/ryu/blob/master/ryu/lib/ovs/bridge.py#L92
However, I don't know which function in this class are more appropriate to do this. A precise example will be highly appreciated. Thank you all
Regards
Arslan
Question
Dear All,
I am wondering if there are some mathematical models to correlate amount of network traffic to operational network parameters such as throughput, delay and packet loss for a given link capacity. Consider that traffic is TCP based traffic.
Further details with reference to multimedia applications, I am considering two applications VoIP and HTTP Adaptive video streaming.
Any useful suggestion in this regard is highly appreciated.
Regards
Arslan
Question
I am trying to find the optimal sampling rate of the passive probe for QoE monitoring of a video streaming application where I am considering the network load as an objective function which should be minimized. I wonder if there are some concrete work in literature related to it. Any useful information will be highly appreciated. Thanks 
Question
I am searching for some literature where "User's churn" has been modelled with respect to Quality of Experience (QoE) in telecommunication. I tried to search it but the articles I have found have not correlated user's churn with QoE and some of them are artificial intelligence based algorithms where I found no publicly available database for it. I look forward for suggestions from community.
Question
I have been searching for some research article to find the benefits of both OTTs and ISPs to collaborate for QoE but I couldn't find some good article which has addressed it clearly. Any help in this regard is highly appreciated.

Question
I am searching for open source/ publicly available software/program for mapping QoS to QoE for network management i-e a program/software based on machine learning algorithm that can calculate QoE e.g Mean Opinion Score (MOS) based on QoS parameters. Any help regarding this will be highly appreciated :)
Question
I would like to know which classifier is best suited for real time applications both in term of performance and computation. The answer with references will be appreciated.
Lets Suppose we have a good computing facility, the application is utilizing hybrid computing (Parallel computing on CPU + GPU Compting) and feature vector is robust and has high dimension. In addition to that, delay of nanoseconds is acceptable then which classifier will be the best for classification task?
Question
I want to acquire RSSI information from a wifi device in my laptop to MATLAB.

Project
The QoE-Net project is a Marie Skłodowska-Curie Initial Training Network with the aim of conducting a high-quality collaborative research among six European countries and South Korea in the domain of Quality of Experience (QoE) in multimedia services. The multimedia traffic has almost captured 80% of Internet traffic nowadays with the recent development in smartphones, tablet PCs, HD video playback devices and high usage of Over The Top servicers (OTTs) like Twitter, YouTube, Facebook etc. However, this requires the Internet Service Providers (ISPs) to put in more resources in order to address the issue of churn of users while ISPs are not in loop of revenue generation between OTTs and users. Moreover, due to increased competition among OTTs, the costumer’s satisfaction is keen interest for OTTs nowadays. Hence, the provision of QoE to end users will not only allow ISPs to get into the revenue loop but also will enable OTTs to address the user needs in the best way. Therefore, QoE is an emerging multidisciplinary field that is getting more attention from researchers in academia, ISPs and OTTs. Being a multidisciplinary field, QoE is more user centric and subjective rather than Quality of Service (QoS), and requires expertise from experts in multiple fields. Nevertheless, to acquire this goal a close scientific and technical collaboration between the experts in industry, academia and standardization institutes is needed. Therefore, the QoE-Net network is composed of seven academic institutions, three industrial partners and one standardization institution. The main focus of this project is to address the provision of QoE to end user for multimedia services like video streaming, IPTV, social networking, mobile gaming etc. with R&D, innovation and technology. The QoE-Net project not only has potential to give a boom to European telecommunication industry but also has a worldwide impact. For more information visit:http://www.qoenet-itn.eu/
