Whatever the Network of the Future turns out to be, there is little doubt that QoS will constitute a fundamental requirement. However, QoS issues and the respective solutions will not remain unchanged. New challenges will be raised; new ways of dealing with QoS will be enabled by novel networking concepts and techniques. Thus, a fresh approach at the QoS(More)
The paper proposes a preliminary design of cross-layer quality of service applied to congestion control in future Internet. This is an alternative solution to QoS-aware routing, whenever the infrastructure operator cannot add new resources, and/or when re-routing is not possible. Dedicated software, running in each node, collects a list of local parameters(More)
Network traffic exhibits strong correlations which make it suitable for prediction. Real-time forecasting of network traffic load accurately and in a computationally efficient manner is the key element of proactive network management and congestion control. This paper compares predictions produced by different types of neural networks (NN) with forecasts(More)
This paper continues the idea of a gearbox-like routing algorithm selection in runtime presented at IEEE LANMAN 2011. Following the results obtained by simulations, the objectives were this time to have a real implementation of the the Modified Dijkstra's and Floyd-Warshall algorithms in OpenFlow. The testbed under Fedora Core consisted on four virtual(More)
This paper presents a possible application of the cross-layer QoS mechanism for network coding in Future Internet. The idea is that the congestion control could be solved for core networks if a network coding-based point-to-multipoint transmission is implemented with quality of service information collected in a bottom-up approach. The implemented testbed(More)
Routing protocols for the Future Internet need to adapt for any given status of the network. However the legacy routing algorithms (e.g. Dijkstra) could not seize the congestion determined by any other event except link failure and/or Layer 2 technology changes. Instead of a sophisticated mechanism we select the most competitive path determination solution(More)
In this paper we describe the design principles and the preliminary implementation of a situation aware intra-domain routing solution, called Situation Aware Multipath (SAMP) routing algorithm. This offers an effective method to increase throughput and to achieve load balancing by attempting to prevent congestion in computer networks. The path selection is(More)
The legacy automatic deployments of OpenStack are mostly focused on specific packets and configurations. This paper investigates the possibility to automate the deployment of both OpenStack and the underlying architecture at once (minimum one Controller Node and one Compute Node). The Chef tool proved to be a good candidate, together with Vagrant (for(More)
Multi-access and heterogeneous wireless communications are considered to be one of the key drivers in the Future Internet. By using existing technologies, the mobile users will be Always Best Connected (ABC) anytime and anywhere while having full access to new communication services. This paper proposes the system architecture of a connectivity platform(More)
Providing ubiquitous connectivity to the passengers of public transportation vehicles is an important goal of the communication system designers in the context of fast development of the intelligent transportation systems and of Future Internet communication technologies. Efficient usage of transmission resources available in the heterogeneous networking(More)
