SDN Routing According to Transmitted Content
Gavryliuk, Olga ; Franková, Barbora (referee) ; Holkovič, Martin (advisor)
This works main point of focus is routing in software defined networks, which allow routing based on transfered packets. For accomplishing this task it was necessary to create a detection mechanism, that finds the connection within the OS which needs priority handling. New connections are sent via a routing aplication which is running on the SDN controller POX. The controller divides applications based on two criteria: The application requiring the largest bandwidth and the application requiring the fastest route. For this purpose four algorithms for routing data based on application preferences were designed and implemented. The applications were implemented in the Python language and they were tested in the simulation tool Mininet.

A Network Control Language for OpenFlow Networks
Antolík, Dávid ; Veselý, Vladimír (referee) ; Ryšavý, Ondřej (advisor)
The main goal of this bachelor thesis is to design and implement a high-level language for declarative configuration of Open-Flow networks. The compiler of the language, data model and interpreter were implemented employing Trema as the underlaying Open-Flow controller. The implementation was tested in a virtual network environment and it was shown that it is fully functional for basic network configurations.

Hardware-Accelerated Cryptography For Software-Defined Networks
Cíbik, Peter
This paper presents a Software-Defined Network (SDN) cryptographic solution targetedon high-speed smart Network Interface Cards (NICs) with an FPGA chip. This solution providesa fast alternative method to develop network-oriented data processing cryptography applications foran accelerator. A high-level programming language – Programming Protocol-independent PacketProcessor (P4) – is used to avoid a complex and time-consuming hardware development. The solutionconsists of two main parts: a library of mainly used cryptographic primitives written in VHSICHardware Description Language (VHDL) i.e. a symmetric cipher (AES-GCM-256), a hash function(SHA-3), a SHA-3-based Hash-based Message Authentication Code (HMAC), a digital signaturescheme (EdDSA) and a post-quantum digital signature scheme (Dilithium), and a compiler P4/VHDLwith the support for these cryptographic components as external objects of P416.
