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 automatic creation and configuration of virtual...
This paper studies the SPLAY open-source framework that facilitates the design, deployment and testing of large-scale distributed applications. A mechanism for automatic control of a virtualized testbed created in OpenStack running Ubuntu 14.04.3 was implemented. The SPLAY entities involved herein were the following: a controller and a modified version of the daemons without using the sandboxing concept...
This paper proposes a solution for active measurement of the Available Transfer Rate needed in a multitunnel architecture with a smart mobile router offering uninterrupted services for its wireless customers. It simultaneously uses several wireless/mobile access networks to the Internet in order to reach the service continuity gateway located somewhere in a broadband network. This customer-oriented...
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 environment, characteristic to today's wireless...
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 switches Open vSwitch 1.3 and a software controller...
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 designed to implement the ABC paradigm for passengers...
The paper is focused on Nagios, an open-source flexible monitoring tool for enterprises. The goal was to add new objects (i.e. QoS parameters) in a management information base MIB starting with the root object identifier OID .1.3.6.1.4.1.8072.9999.9999.1. Furthermore, we wanted to prove that the integration of this enhanced software tool running on several platforms (Android, Windows7, Fedora Core)...
This paper presents a monitoring application for quality of service parameters, called iQoSStats, dealing with Available Transfer Rate and One-Way Delay. The tool is running on iOS5-based iPad terminal. Due to the lack of Java support, a proxy server is needed to allow the connection to the cloud computing solution based on OpenNetInf. It relies on an information-centric communication paradigm and...
This paper presents new facilities added to the existing Information Object (IO) Management Tool used in the open-source implementation of NetInf (Network of Information). The project was realized within a virtual machine running Ubuntu 10.10 and the contributions to the source code developed in Eclipse environment refer to the following: a) a more friendly way to introduce the search criteria, by...
The paper is focused on the Floyd-Warshall all-paths routing algorithm, presenting its first implementation in OMNeT++ simulator. The experiments are trying to demonstrate that Floyd-Warshall's use for a routing protocol is more efficient from infrastructure provider's perspective. The performances are compared to the results obtained when employing distance-vector protocols (such as RIP) or link-state...
The dynamics of modern communication networks, especially regarding the user's behavior, determine the necessity of an effective routing protocol that can ensure high performance. In this paper we present the implementation and performance evaluation of a new dynamic multipath routing solution, called Situation Aware Multipath (SAMP), using the OPNET Modeler. The main features of our solution are...
The integration of cooperation and coding techniques into communication networks could enable an efficient use of the network resources. The paper proposes an architecture framework for cooperation aware communication networks involving a new paradigm called Generic Path (GP), which is a key concept for the Future Internet. Furthermore an algorithm is discussed herein, instantiating the cooperation...
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 such as available transfer rate and one-way...
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 based on statistical cross-layer Quality...
The paper proposes a signaling protocol for network coding-based congestion control and it evaluates its performances The theoretical aspects presented herein justify the expected benefits, i.e. increased throughput of the flows passing through the congested network, as well as the decreased delays and number of packets lost. The signaling protocol proposed was simulated in OMNeT++ to demonstrate...
