Network virtualization has emerged as a powerful technique to deploy novel services and experimental protocols over shared network infrastructures. Although recent research has highlighted field programmable gate arrays (FPGAs) as attractive platforms for high performance network virtualization, these devices remain inaccessible to the larger networking research community due to the absence of userfriendly programming models. A programming model that can abstract the intricacies of the hardware

In this paper, we present ReClick, a framework to efficiently design and deploy reconfigurable dataplanes for FPGA-based network virtualization systems. A hardwareagnostic programming model is described that allows developers to focus on the virtual dataplane semantics rather than the implementation details. The framework exposes interfaces similar to the popular software router development framework, Click, and promotes design reuse. Optimization strategies are included in ReClick which use similarities between virtual dataplane configurations to implement multiple planes in an area-efficient manner. Dataplanes exhibiting up to 1 Gbps data rate have been automatically compiled and tested in hardware in a NetFPGA platform.
