Data centers availability is mandatory and is conditioned by a quick response to failures and attacks thanks to efficient live forensics. However, this task is lately impossible to complete with classic systems because of encountered data rates and service diversity. Moreover, Software-Defined Networking (SDN) devices agility requirements prevent the use of Application Specific Integrated Circuits...
The development of a network centered life has increased overall data rates in core networks. Thus, data centers face the challenge to provide always more services at higher data rates while reacting quickly to complex failures and more powerful attacks thanks to efficient network forensics. Moreover, Software-Defined Networking (SDN) becomes a standard which offers agility but also requires forensic...
As the growth of Internet traffic volume and diversity continues, passive monitoring and data analysis, crucial to the correct operation of networks and the systems that rely on them, has become an increasingly difficult task. We present the design and implementation of Blockmon, a flexible, high performance system for network monitoring and analysis. We present experimental results demonstrating...
Understanding the composition of the Internet traffic has many applications nowadays, mainly tracking bandwidth consuming applications, QoS-based traffic engineering and lawful interception of illegal traffic. Although many classification methods such as Support Vector Machines (SVM) have demonstrated their accuracy, not enough attention has been paid to the practical implementation of lightweight...
1 Applications requiring network Quality of Service (QoS) (e.g. telepresence, cloud computing, etc.) are becoming mainstream. To support their deployment, network operators must automatically negotiate end-to-end QoS contracts (aka. Service Level Agreements, SLAs) and configure their networks accordingly. Other crucial needs must be considered: QoS should provide incentives to network operators, and...
