We investigate the control and data message overhead when the IoT is supported over an integrated satellite-terrestrial network based on Information-Centric Networking (ICN). We consider a scenario where IoT sensor networks are connected via LEO satellites and present three optimization models: polling and data aggregation at a proxy, confidential data transfer using a single proxy, and individual...
A well-known technique for enhancing the performance and stability of content distribution is the use of multiple dissemination flows. Multipath TCP (MPTCP), the most popular multiflow protocol on the Internet, allows receivers to exploit multiple paths towards a single sender. Nevertheless, MPTCP cannot fully exploit the potential gains of multipath connectivity, as it must fairly share resources...
The high bandwidth and low delay requirements of Networked Music Performance (NMP) often lead to doubts about its feasibility in wide area networks. Multipath routing with Quality of Service (QoS) constraints is one way to meet these requirements, as it offers bandwidth aggregation while keeping latency low. However, IP does not natively support multipath QoS routing, requiring complicated extensions...
Aiming to improve the performance of on-demand video streaming services in an Information-Centric Network, we propose a mechanism for selecting multiple delivery paths, satisfying bandwidth, error rate and number-of-paths constraints. Our scheme is developed in the context of the Publish-Subscribe Internet architecture and is shown to outperform state-of-the-art multi-constrained multipath selection...
In-network packet-level caching is one of the most promising features offered by Information-centric Networking (ICN) architectures. In ICN, routers can use their queueing buffers as temporal storage units, thus allowing on-path caching by exploiting the network's storage resources. Packet-caches can be highly beneficial for content delivery, but they are also known to have three significant weaknesses:...
Routers in the Content-Centric Networking (CCN) architecture maintain state for all pending content requests, so as to be able to later return the corresponding content. By employing stateful forwarding, CCN supports native multicast, enhances security and enables adaptive forwarding, at the cost of excessive forwarding state that raises scalability concerns. We propose a semi-stateless forwarding...
Information-centric networking (ICN) constitutes an alternative to the conventional, IP-based, internetworking, with information itself being identified rather than the host where it resides. This approach introduces powerful tools and operations for content delivery, such as native support for multicast. Exploiting this native multicast capability is a very promising approach for multimedia applications...
Information-Centric Networking (ICN) is becoming increasingly popular: various architectures have been proposed to transform today???s host-centric networks to information-centric ones. An important question that begs to be answered is whether the ICN paradigm can adequately support various types of existing network usage, as well as set the foundations for new application types. In this demonstration,...
The recent paradigm shift in the Internet's usage, from the host-centric to a content-centric communication model, where users request information irrespectively of its location, is coupled with an increasing need for converged and seamless access over heterogeneous wired and wireless networks. By integrating satellite communication components into a publish-subscribe Information-Centric Networking...
