In Content-Centric Networks (CCN), multiple routers may cache the same content, which makes it possible to retrieve the content chunks in parallel. In this paper, we propose Multi-Source Request and Transmission mechanism (MSRT) for CCN. We develop a MinMax problem to compute the optimal solution to retrieve all the chunks from multiple sources in the shortest time. We prove that the problem is NP...
The main usage pattern of the Internet is changing from end-to-end communication to content distribution and access. To support this change, the actual Internet has several add-on as Content Delivery Networks (CDNs) and Web caches.
MobilityFirst (MF), as a realization of Information Centric Network architecture, places intelligent functionality, such as storage and reliability, inside the network to assist with data delivery. The MF architecture requires effective congestion and flow control to efficiently support data delivery at scale. Traditional end-to-end, window-based congestion control like that used by TCP is unsuitable...
Named-Data Networking architecture relies on cache networks, where nodes store the data for further requests. However, the memory needed at each node called Content Store represents the most significant part of the entire cost of the infrastructure that has to be supported by network providers, making difficult the change from the current Internet infrastructure to a Future Internet based on NDN....
Media streaming has largely dominated the Internet traffic and the trend will keep increasing in the next years. To efficiently distribute the media content, Information-Centric Networking (ICN) has attracted many researchers. Since end users usually obtain content from indeterminate caches in ICN, the publisher cannot reinforce data security and access control depending on the caches. Hence, the...
We propose a recursively scalable DC infrastructure starting off from simple DC nanogrids (subsystem) that are interconnected via a DC power bus line to form a cluster. We have conceived a non-droop based procedure to exchange power from one subsystem to another in order to balance demand/generation fluctuations within the community without requiring any central monitoring or control. To scale the...
The objective of this work is the investigation of a possible collaboration between Over-The-Top (OTTs) service providers and Internet Service Providers (ISPs), which is centered around the Quality of Experience (QoE). Initially, we define a reference architecture with the required modules and interfaces for the interaction between the two providers. Then, we focus on the modeling of the revenue,...
With the evolution of the current use of the Internet and the volume of content exchanged through the web, huge datacenter networks (DCN) are deployed to take into account the diversification and mass of contents. In these datacenters, the architecture is an important component that has a great impact on its performance. In addition, the communication inside them is usually IP-based, which has been...
Development and implementation of appropriate e-services as well as revenue generation are key to deploying and sustaining ICT installations in poor areas in developing countries. The area of e-Health is a promising area for e-Services that are important to populations in poor areas and health service organisations that are already spending money on different health initiatives in these areas. This...
The Named Data Networking (NDN) and Content-Centric Networking (CCN) architectures advocate Interest aggregation as a means to reduce end-to-end latency and bandwidth consumption. To enable these benefits, Interest aggregation must be realized through Pending Interest Tables (PIT) that grow in size at the rate of incoming Interests to an extent that may eventually defeat their original purpose. A...
In this paper, we present a new authentication architecture for Taiwan High Speed Rail (THSR). The new authentication architecture applies multiple outbound LTE gateways. We also propose an SDN-based authentication method using post-authentication that is suitable for high-speed environment, including THSR. The proposed architecture and method can reduce network congestion and shorten the authentication...
The Recursive InterNetwork Architecture (RINA) is a general architecture for all forms of computer networking, based on a single type of programmable layer that recurs as many times as required by the network designer. The recursion and programmability aspects of RINA are key to design flexible, heterogeneous networks while still bounding their complexity. In this paper we show how the programmability...
Traditional network management is tied to the TCP/IP architecture, thus it inherits its many limitations. Additionally there is no unified framework for application management, and service providers have to rely on their own ad-hoc mechanisms to manage their application services. The Recursive InterNetwork Architecture (RINA) is our solution to achieve better network management. RINA provides a unified...
In this work we present the remote control of the tank level system. The physical system is controlled in real time using local or Internet network. The client could manage the remote experiment through a simple web browser via a graphical shared user interface. The study is based on the PID identification parameters according to Ziègler-Nichols methods. After the identification of the PID parameters...
In the Internet of Things (IoT) vision, all our everyday objects will be equipped with processing, sensing and actuating capabilities and need to be connected to the Internet to provide their full potential benefits. Our life will be surrounded by an ecosystem of smart "things" that need to be found, accessed, managed and interconnected to other things. For that purpose, we introduce an...
Cloud computing and Internet of Things (IoT) represent two different technologies that are massively being adopted in our daily life, playing a fundamental role in the future Internet. One important challenge that need to be handled is the enormous amount of data generated by sensing devices, that make the control of sending useless data very important. In order to face with this challenge, there...
Software-Defined Networking (SDN) has evolved as a new networking paradigm to solve many of current obstacles and limitations in communication networks. While initially intended mainly for single-domain networks, SDN technology is going to be deployed also to large cloud-based data centers where several customers, called tenants, share network resources. In a multi-tenant environment, the SDN technology...
Web Technology is the development of the mechanism that allows two or more computer devices to communicate over a network. To understand such a complex system there is a need of experiential learning. Authors adopted an "Experiential learning" for teaching the web technology course. Teaching with a hands-on session where the teacher explains the concepts with demonstration and students simultaneously...
In recent years, there has been a trend towards changing the Internet paradigm from location-based to content-based. Based on the principle that networks should allow users to focus on data, rather than having a reference to a physical location where that data is, the adoption of new paradigms can be justified. Information-Centric Networking (ICN) is a new paradigm that gives a potential improvement...
We are witnessing a growing interest around thecost of security in terms of energy consumption. For instance, in wired networking, some proposals have been put forwardto try to balance the efficacy of intrusion detection with theneed to save energy dynamically, by changing the amount ofresources dedicated to security analysis and routing on the basisof current load. These hybrid energy-aware Routers/IntrusionPrevention...
