This paper proposes a novel end-to-end QoS framework, called Self-Adaptive bandwidth Reconfiguration QoS framework (SAR). SAR provides end-to-end QoS guarantees on a per-flow basis through admission control and end-to-end bandwidth reservation. In order to adapt to short and long time traffic load changing, SAR performs dynamic bandwidth reconfiguration.(More)
In the context of the new technologies and applications of Future Internet, computer networks skills are greatly valued and an increased number of qualified specialists is required. Cisco Networking Academy, the world's largest classroom and a major player in the communication network area, offers its students a powerful network simulator - Packet Tracer.(More)
This paper presents the design and implementation of a benchmarking system for QoS (quality of service). The application generates traffic patterns, measures and computes the QoS parameters and stores and displays the results both in numerical and graphical form. The main advantages of this system are the traffic patterns complexity, the accuracy of the(More)
The paper focuses on the problem of interconnecting different cloud providers with the aim of offering enhanced services. The Intercloud scenario is based on the key concept that any cloud by itself does not have infinite natural resources or stable geographic location. The paper presents a distributed architecture for interconnecting existing cloud(More)
This paper presents the design and implementation of an embedded system for real-time network flow identification. The system identifies data flows based on packet inspection. The main advantage of this system is that it reduces significantly the processing time required for the flow identification. For the hardware implementation, a Xilinx Virtex-II Pro(More)
One of the main concerns of the current Internet, in terms of Quality of Service, is guarantying end-to-end delivery of services over heterogeneous networks, where more than one management entity exists. Due to the complex, underdeveloped business relations among ISPs and a low level of trust, new QoS frameworks are being designed to guarantee reachability,(More)
Proxy Mobile IPv6 environments are able to provide mobility for telecommuters, without application-level interruptions. This technology is used for network-based IPv6 Mobility management to Mobile Nodes. The proposed test bench allows for analyzing, developing and testing adaptive routing algorithms between Proxy Mobil IPv6 entities. The test bench(More)
End-to-end QoS (Quality of Service) provisioning over heterogeneous networks is a major challenge. The poor communication between Service Providers, the increasing complexity of the supported services, the need for fulfillment of end-toend requirements represent the main problems to be solved by the new QoS frameworks. This paper presents a novel system(More)
Quality of service frameworks in computer networks are sets of mechanisms that run over multiple network equipment with the aim of ensuring network services. Several frameworks have been developed using different approaches, each framework showing advantages but also drawbacks. In order to eliminate these shortcomings, a new organization of the bandwidth is(More)
