“…However, interworking with switching or routing hardware is not considered as of yet. In this paper we aim to achieve a seamless integration between the C-board [1] Generic Packet Forwarding architecture and the control protocols running on the Linux-based PC board. Figure 1 depicts the functional separation and the place of the defined -general -interface.…”

The practical validation of investigating new router architectures and control algorithms is troublesome. It is partially due to the lack of programmable architectures that are fast enough for current networking, widely programmable, and equipped with the great variety of protocols that routers and switches has to handle. The idea of open, software-based routers running on commodity hardware have spread in recent years, resulting several practical implementations of so called softrouters. Beside the economic advantages of having the Forwarding Element functions tackled by commodity Network Interface Cards (NICs), this approach suffers from issues of suboptimal performance. This is partly due to the fact that all forwarding decisions are made by the main CPU instead of involving local processors at the NICs. Separating the functions into Forwarding Element and Control Element by the ForCES framework enabled the development of new control algorithms and protocol implementations for routers, however there are no widely available implementations. This paper describes a solution that is utilizing programmable hardware accelerators at the Forwarding Element, while keeping the advantages of open, Linux-based software-based router implementations. The hardware accelerators are implemented in the C-board, a reconfigurable, FPGA-based networking platform. The interoperability with existing Control Elements are described together with an analysis of features and capabilities of this combined solution.

Before the advent of FPGAs (Field Programmable Gate Arrays), hardware acceleration of networking equipment has been implemented through static architectural elements. The new generations of these highly flexible FPGA architectures can be reconfigured on-the-fly, allow parallell processing of data arriving at high-speed, and even contain hundreds of DSPs (Digital Signal Processors), to further parallelize certain, computationally intensive tasks. This paper demonstrates some of the capabilities of a new, FPGA-based networking platform, C-GEP. This multi-purpose, programmable platform can support various tasks, from being a high-speed switch/router, through preprocessing packets for Deep Packet Inspection, towards being the Forwarding Plane element in the SDN infrastructure. The current demonstration contains two further implementations of 100 Gbit/s-capable applications: a traffic generator -firing off multi-encapsulated packets -and a lossless traffic monitor -that is able to classify and steer the monitored traffic to further postprocessors.
