    Monitoring of Overlay Networks With Virtual Resources

    Overlay networks with virtual resources need special forms of monitoring. The paper describe the development of a monitoring system for the Federated E-infrastructure Dedicated to European Researchers (FEDERICA) network. The paper describes the whole concept and the possibility of getting basic Input/Output (I/O) statistics from different layers of the network....

    Realistic Passive Packet Loss Measurement for High-Speed Networks

    Realistic and accurate packet loss measurement of production traffic has been challenging, since the frequently-used active monitoring approaches using probe packets cannot capture the packet loss experienced by the traffic of individual user applications. In this paper, the authors present a new approach for the accurate measurement of the packet...

    Designing a Hardware-Accelerated Firewall With Two 10 Gbps Ports

    High-speed packet filtering should be one of the first steps in securing any modern computer network. However, solutions over 1 Gbps are practically impossible to implement in software, and must be implemented with the use of specialized hardware. This paper describes the design of a two-port firewall for 10 Gbps...
