【 摘 要 】

Enhancement of network data-plane functionality is an open problem that has recentlygained momentum.Addition and programmability of new functions inside the networkdata-plane to enable high speed, complex network functions with minimum resourceutilization, is main focus of this thesis.In this work, we look atdifferent levels of the network data-plane design and using networkvirtualization and software defined networking we propose data-planeenhancements to achieve these goals. This thesis is divided into two parts, in first part we take a ground up approach wherewe focus our attention at the fast path packet processing. Using hardware and software based network virtualizationwe show how hardware and software based network switches can be designed to achieveabove mentioned goals.We then present a switch design to quickly add thesecustom fast path packet processors to the network data-plane using software defined networking.In second part of this thesis we take a top to bottom approach wherewe present a programming abstraction for network operators and a network function deployment system for this programming abstraction. We use network virtualization and software defined networking to introduce new functions inside the network data-planewhile alleviating the network operators of thedeployment details and minimizing the network resource utilization.
