Acceleration of Open vSwitch
Vodák, David ; Orsák, Michal (referee) ; Martínek, Tomáš (advisor)
Virtual switch is a program, which is used for connecting virtual machines to network and that is why it is a crucial part of server virtualization. However virtual switch is consuming too much performance of the server which it is running on. A measurement of Open vSwitch (OvS) indicates that for data speed of 10 Gb/s, approximately 4 cores of the processor are fully occupied. As the consumption of performance is directly proportional to transmission speed, it may eventually get to the point where the consumption of performance cannot be handled. This bachelor thesis is about acceleration of the Open vSwitch with the help of the DPDK Poll Mode Driver extended by support of the SR-IOV virtualization technology as well as the interface for offloading classification rules to hardware called RTE flow. In the scope of this thesis the SR-IOV is implemented and then tested on OvS. Furthermore, the RTE flow support was designed and partially implemented.

SDN for cloud computing
Kuklovský, Adam ; Frolka, Jakub (referee) ; Slavíček, Karel (advisor)
The theme of this bachelor work is SDN technology. It consists of both practical and theoretical part. In theory section, we described the main concept of the SDN network, functioning of OpenFlow protocol, comparison of individual open source SDN controllers and real onset of SDN technology. Practical section contains procedure of individual components being installed to create topology and to forward realization of laboratory task. The laboratory work also depicts the way of creation and modification of streams in the SDN network.

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.

Testing Open vSwitch and DPDK
Šabart, Otto ; Grégr, Matěj (referee) ; Čejka, Rudolf (advisor)
The project is about the virtual switch called Open vSwitch and its architecture. It deals with an acceleration of the switch mainly by using Data Plane Development Kit (DPDK). Furthermore, it describes the architecture of the DPDK kit and analyses the individual functional units. Furthermore, it describes the architecture of the DPDK kit, analyses the individual functional units and describes the possibilities of its configuration. Another part of the project describes the methodology chosen for a performance testing of virtual switches. Subsequently, this methodology was used to make a design and environment implementation for fully automatic Open vSwitch s DPDK performance testing with the use of automatic systems such as Koji, Jenkins, Beaker a VSperf. Simultaneously, the tools for automatic comparison of produced results were implemented. The created environment was then used for the performance measurement of several basic Open vSwitch configurations with and without the use of DPDK. The implemented measurements are discussed and evaluated in the project. The final project's stage provides a great amount of the enlargement and improvement of the implemented tests.
