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.

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.
