OVS Acceleration Using FPGA Acceleration Card
Vido, Matej ; Martínek, Tomáš (referee) ; Kořenek, Jan (advisor)
The performance of the virtual switch Open vSwitch (OVS) is insufficient to satisfy the current requirements for link bandwidth of the server connections. There is an effort to accelerate the OVS both in the software and in the hardware by offloading the datapath to the smart network interface cards. In this work the COMBO card for 100G Ethernet developed by CESNET is used to accelerate the OVS. The suggested solution utilizes the firmware for FPGA generated from the definition in the P4 language to classify the packets in the card and DPDK for the data transfers and offloading the classification rules into the card. Forwarding of one flow with the shortest frames from physical to physical interface using one CPU core reaches forwarding rate of 11.2 Mp/s (10 times more than the standard OVS) with classification in the card and 5.9 Mp/s without classification in the card.

DPDK for COMBO Network Cards
Vido, Matej ; Dvořák, Milan (referee) ; Viktorin, Jan (advisor)
Software framework Data Plane Development Kit provides a standard API for fast packet processing in the user space. The DPDK covers multiple devices and architectures from different vendors. The CESNET association develops the family of COMBO network cards that are able to process Ethernet traffic up to 100 Gb/s through their SZE2 interface. This thesis describes the design and implementation of the DPDK user space driver for COMBO network cards. The driver is called szedata2 and has already become a part of the DPDK mainline in the version 2.2.0 (December 2015). The thesis describes also the measurements and the accomplished results. Packets have been received and transmitted at the wirespeed of the 100 Gb/s link.
