IMS: The New Generation of Internet-Protocol-Based Multimedia Services
No full textLegacy networks, both fixed and mobile, which were originally designed for voice communications, are progressively migrating to new infrastructures that promise to revolutionize the services offered. In this paper, we will cover this new generation of personal communication services, with an emphasis on the family of Internet protocol (IP)-based multimedia subsystem (IMS)-aided infrastructure that relies on the session initiation protocol (SIP). As a benefit, the end users will enjoy a new generation of personal communications services that are accessible anywhere and anytime. These services are timedia subsystem (IMS)-aided infrastructure that relies on the directly related to the end users rather than to their diverse devices. It is anticipated that the new deployments of next-of the IMS technology. generation networks (all-IP based) will accelerate the adoptio
Perceptions of intellectual property: a review
No full textIn “The right to good ideas: patents and the poor”, The Economist depicts two driving forces in the contemporary discourse on IP and globalization. The one is interested in advancing the knowledge economy, an approach based on the belief that knowledge is the driving factor behind economic growth. The other resides on a belief that IP is a major means to advance the process of globalization. While the former is strongly motivated by new economic growth theory, as for example advanced by Stanford professor Paul Romer, the latter is based on typical anti-globalization arguments, such as for example the position that the IP system helps multinational companies to build up monopolies to the detriment of the poor, drives small and medium-sized enterprises (SMEs) and local business in developing countries out of business and increases prices for consumer products, be they pharmaceuticals or software. The purpose of this review is to help understand the current discourse on intellectual property, to grasp underlying themes, assumptions and connotations associated with the term “IP”, so as to identify paths leading to a more comprehensive understanding of IP and the opportunities and pitfalls it may provide
Efficient Learning of Communication Profiles from IP Flow Records
No full textThe task of network traffic monitoring has evolved drastically with the ever-increasing amount of data flowing in large scale networks. The automated analysis of this tremendous source of information often comes with using simpler models on aggregated data (e.g. IP flow records) due to time and space constraints. A step towards utilizing IP flow records more effectively are stream learning techniques. We propose a method to collect a limited yet relevant amount of data in order to learn a class of complex models, finite state machines, in real-time. These machines are used as communication profiles to fingerprint, identify or classify hosts and services and offer high detection rates while requiring less training data and thus being faster to compute than simple models.Accepted author manuscriptCyber Securit
Scalable QoS-aware Mobility for Future Mobile Operators
No full textTelecom operators and Internet service providers
are heading for a new shift in communications
paradigms. The forthcoming convergence
of cellular and wireless data networks is often
manifested in an “all IP approach” in which all
communications are based on an end-to-end IP
protocol framework. The approach to network
design becomes user and service-centered, so
that continuous reachability of mobile users and
sustained communication capabilities are default
requirements for a prospective architecture. In
this article, we describe a network architecture
which is able to provide seamless communication
mobility, triggered either by the user or by the
network, across multiple technologies. The architecture
allows for media independent handovers
and supports optimized mobility and resource
management functions. The main focus of the
article is on major technical highlights of mobility
and quality-of-service (QoS) management subsystems
for converged networks.Publicad
Malicious IP Address Prediction
No full textabstract: IP blacklisting is a popular technique to bolster an enterprise's security, where access to and from designated IP addresses is explicitly restricted. The fundamental idea behind blacklists is to continually add IP addresses that reputable entities, such as security researchers, have labeled as malicious to the list. Currently IP blacklisting is a reactive method, where malicious IP addresses are identified after their engagement in malicious activities is detected (e.g. hosting malware samples or sending spam emails). This thesis project aims to address this issue, by laying the groundwork for a machine learning tool that proactively identifies malicious IP address. The ground truth data derives from VirusTotal, a company that synthesizes security knowledge from prominent sources, such as Symantec, Fortinet, and ESET. I passed 307,621 IP addresses found in posts on the D2web (deep and dark web) through VirusTotal. If at least one detected URL associates with the IP address and VirusTotal deems it positive, I accordingly label the IP address as positive (malicious), and negative (non-malicious) otherwise. To give some insight into the ground truth, 6,147 IP addresses were identified as positive from the original 307,621. Furthermore, in order to quantify the prediction capabilities of our models, I introduce a metric called lead time. Lead time represents the difference between the date an IP address was first seen on the D2web and its earliest date on VirusTotal. For example, if an IP address was mentioned on the D2web on 1/5/2017 and mentioned on VirusTotal on 1/25/2017, then its lead time is 20 days. After feature selection, where I handpicked features from the data mined from the D2web, I attempted various combinations of classifiers and feature sets in order to create the best model. The final machine learning models implement temporal cross validation - where I train a model on data from 1/1/2016 up until a testing month in 2017, and test on data from the testing month - with a Random Forest classifier. The following are results from a model that was tested on January 2017, which exhibits median performance among the final models. The true positive rate is 0.2558, the false positive rate is 0.3612, and the average lead time (for leading true positives) is 193 days, where the model picks up 33.33% of all leading true positives. Although the model finds a respectable number of true positives, it picks up too many false positives. Thus, my approach is ineffective at predicting malicious IP addresses in their current state, meaning additional efforts will be required to transform the current work into a viable too
The Usage of MPLS in Voice over IP Network
No full textAbstract: The article focused on the usage of Multiprotocol Label Switching (MPLS) over VOIP network. One of the features that MPLS has is Traffic Engineering (TE) which can help overcome potential pot holes in the network or to circumvent sub-optimal paths, especially in a network consisting of a diverse geographical terrain. The prevalence of MPLS IP VPN networks make them the de facto transport for inter-connecting IMS based VoIP devices. Inevitably, this creates the need for a fundamental set of guidelines, which can ensure that the quality of service for real time traffic is acceptable. To that end, a systematic approach was taken to implement traffic engineering LSPs which enabled the real time multimedia traffic to be delivered with highest priority and minimal loss and delay. This helped provide tangible network operations benefits such as, early detection of service disruption because of faults in the desired end to end label switched paths, reduction of the Mean Time to Resolve (MTTR) and lead to proposals for further improvements which could produce a more intelligent re-routing of the LSPs

IP & Collaborative Agreements in the Creative Industries: Interim Report
No full textThe AHRC Creative Industries Clusters Programme (CICP) is a radical departure from traditional research funding. Research is understood in the context of R&D collaborations that are conceived to lead to new products and services, and ultimately to increased productivity and economic growth. These are ambitious, perhaps unprecedented goals for arts and humanities funding.
The experimental nature of creative R&D collaborations between Universities and industry, the subject matter of this report, requires new and innovative collaborative models and considerable cultural adaptation. We cannot know what works best at the outset. But consortium leaders and collaborators need to know the state of the art: what is the orthodox approach to managing and exploiting intellectual property (IP) (where IP is seen as a ‘thing to be sold’), as well as, more fluid iterative interactions (where IP may be viewed as an enabler and catalyst to achieve wider goals, such as increasing capacity and developing an ecosystem).
This report does not aim to provide a set of IP exploitation templates. It is designed to instigate discussion and draw attention to recent research and resources that make it possible to develop bespoke solutions. The aim is to achieve a better understanding of the environment and to enable collaborators on the Creative Industries Clusters Programme to make informed decisions.
The report is structured in 5 sections. Section 1 provides a brief introduction to different forms of intellectual property (including patents, trade marks, design rights, copyright & confidentiality). As copyright regulates much of the creative industry’s output, the report includes a crash course on copyright law, drawing on the resources of CopyrightUser.org, a guidance portal developed by CREATe research. Different types of copyright works are explained, the criteria for protection, the difference between authorship and ownership, how there are economic (linked to owner) and moral (linked to author) imperatives in the copyright system, and, finally, how licensing is used to exploit copyright works.
Section 2 focuses on the resurgence of creative reuse that appears to be a function of the digital environment. It is rare that new products or services do not touch on, be inspired by or adapt existing creative productions. There are opportunities within copyright law, due to the availability of public domain materials and limitations placed by law on the scope of copyright protection, but there are also real risks where exploitation becomes impossible without a careful understanding of joint creation and the need to obtain permissions.
Section 3 explains the current practice of collaborative agreements between the University sector and industry, focussing on the so-called Lambert approach, a toolkit of model agreements that has wide currency in science and technology collaborations. An important difficulty of the Lambert approach is the complexity and formality of the language used that seeks to provide legal clarity for future scenarios before the market potential of the collaboration can be assessed. In the creative industries, it is often necessary to revisit agreements at a later stage, typically once scalability becomes viable. Tying too many knots at the outset may provide legal assurance but also stifle the growth potential of the collaboration. Without concrete examples, it is difficult to envisage how IP arising from collaborative projects is translated into the real world.
Section 4 shares 4 case studies, each from a different creative sector and using a different R&D approach. First, the traditional Hollywood ‘Studio’ approach is presented as the paradigm for consolidating all IP in one production entity, providing maximum freedom for subsequent exploitation; secondly, a more mixed approach of using copyright material for audio-visual production with overlapping layers of different licences for different subject matter is explained; thirdly taking cues from a rapidly developing technology sector, product development over open source licensed artificial intelligence (AI) platforms is explored; and finally a case study from the galleries, libraries, archives and museums sector contrast different attitudes to the use of public domain materials.
The report concludes with Section 5 entitled ‘pitfalls and challenges’. This suggests a number of issues that decision makers should reflect on when seeking to manage IP in collaborative agreements:
– the difficulty of distinguishing background and foreground IP in creative projects, especially under conditions of iterative production involving users;
– the importance of trust in creative relationships and the need to devise contractual ownership agreements rather than relying on joint authorship provisions of the law;
– the ‘nobody knows’ characteristic of cultural production, where prediction of future success is elusive but potential windfalls are high (due to the ‘winner-take-all’ tendency of creative markets);
– the need to understand the use of options to collaborate under conditions of uncertainty, and the advantages of building future freedoms to operate into the R&D process;
– clarification of IP issues in augmented and virtual reality (AR/VR) which usually contain a wide range of potential subject matter, including technology and third party cultural materials;
– the temptation of micro-enterprises and SMEs in the creative sector to avoid engaging with IP, due to time, knowledge and financial pressures;
– an understanding of the ‘negative space’ under copyright law, where it may be difficult to draw the line between ideas and expressions, and where alternatives to enforcement may be needed, such as brand identity and first mover advantages;
– open access obligations that cover research outputs in the context of the UK Research Excellence Framework (REF);
– navigating and challenging the established culture of University technology transfer offices, shaped by a culture that often results in risk averse processes of managing and exploiting IP.
The radical nature of new R&D collaborations in the creative industries will require new approaches. There is a need for policy buy-in at the highest level from both research funders and collaborating Universities. Experimental collaborative models will not come risk free. Innovative and adaptive approaches, open and closed, exclusive and non-exclusive need to be encouraged. There can be no hiding in walled gardens
Telefonie via Internet Protocol (IP): Het effect op Bedrijfsnetwerken
No full textSinds 1995 zijn er diverse Produkten die het mogelijk maken om via IP-netwerken te telefoneren. Door de standaardisatie van deze produkten, de ontwikkeling van gateways naar het PSTN en het toevoegen van multimedia-features, wordt Telefonie via IP een steeds geschikter alternatief voor traditionele telefonie via telefoonnetten. Voordelen van Telefonie via IP zijn de lagere kosten voor lange-afstand verbindingen, de mogelijkheden voor nieuwe diensten en de mogelijkheid om spraak en data te integreren op één netwerk. Een belangrijk nadeel van Telefonie via IP wordt gevormd door de vertraging die het geluidssignaal oploopt in het netwerk. Om dit op te lossen, is de toevoeging van een prioriteiten-mechanisme aan het Internet Protocol noodzakelijk. Om de bandbreedte-belasting van telefonie op het IP-netwerk vast te stellen, zijn metingen uitgevoerd. Met name bij toepassing van zogenaamde low-bitrate spraak-codering is de belasting per spraakverbinding gering vergeleken met de grote bandbreedtes die op de meeste netwerken beschikbaar zijn. Ook wordt de spraak-informatie op een efficiëntere manier getransporteerd dan bij het “gewone” telefoonnetwerk het geval is. De meetresultaten zijn toegepast op de (denkbeeldige) situatie waarbij het telefoonverkeer binnen het Elektro-gebouw van de TU Delft via IP zou plaatsvinden. Een gevolg van het toepassen van Telefonie via IP binnen bedrijven is dat de PABX in zijn huidige vorm zal verdwijnen. De functies van dit systeem zullen verspreid worden over de ITinfrastructuur van het bedrijf.Electrical Engineering, Mathematics and Computer ScienceTelecommunicatie- en Verkeersbegeleidingssysteme

Digital Convergence and IP Divergence
No full textThis chapter proposes a legal, political, and social framework for a nation to formulate proper copyright policy and minimize the risk of potential IP trade conflicts in the digital age. It examines the challenges that the Internet and digital technology present to the traditional copyright legal system. It reviews and compares the copyright history in the U.S. and China, and explores major rationales behind copyright policies of these two countries as well as the main reasons why they were able to avert potential IP trade wars in recent years. By drawing on their experiences, the author argues that the interest of a country is only best served by tailoring its IP regimes to its particular economic and social circumstances. The author believes a nation’s copyright policy should always strike a sound balance of IP protection and social development, and makes some specific suggestions on how to achieve this in the digital age.</jats:p
