Acceleration of Open vSwitch in DPDK
Vodák, David ; Kučera, Jan (referee) ; Martínek, Tomáš (advisor)
Virtual switch is a software that connects virtual machines to the internet, which makes it a crucial part of virtualization on servers. Nevertheless, it can be rather ineffective when it comes to high speed traffic, since it switches all frames in the software. This thesis is about hardware acceleration of the virtual switch called Open vSwitch. The acceleration prototype, which is the goal of this thesis, is based on the RTE flow interface, the SR-IOV standard, and Intel PAC N3000 card. In the scope of this master's thesis, all necessary technologies were described and the acceleration prototype was designed, implemented, and tested. Results of executed measurements indicate increased throughput when rules of the acceleration prototype were offloaded to hardware.

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.
