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.

Flexible Load Balancer Using P4 Language
Šesták, Jindřich ; Fukač, Tomáš (referee) ; Martínek, Tomáš (advisor)
Currently servers of internet services are usually grouped together into clusters to provide sufficient performance to serve clients' queries. Each cluster needs Load Balancer, so it can choose one server which will process query from one client. For describing such device that processes packets is convenient to use P4 language. Within this work, the principles of load balancing, design, implementation and testing of a simple Load Balancer described in P4 language were demonstrated. The program is tested using Behavioral model of P4 language on a common processor and on the NFB-200G2QL card thanks to the Netcope environment from the CESNET association
