Implementation of mechanisms providing Segment Routing for IPv6 (SRv6) using the FD.io VPP platform
Mjasojedov, Igor ; Dvořák, Jan (oponent) ; Koláčková, Aneta (vedoucí práce)
The development of the mobile networks of fifth-generation (5G) accomplishes the requirements of transported services. New applications and services put high pressure on bandwidth, reliability and flexibility of the data transport. Due to this trend, network technologies need to be developed to address it and ensure transmission quality. This master's thesis aims at the Segment Routing (SR) concept and its commitment to improving transport quality in the transport part of 5G mobile networks. SR allows the integration of network programming into the traditional design of transport networks. SR uses either MPLS (SR-MPLS) or IPv6 (SRv6) on the forwarding plane. This thesis aims at SRv6. The main goal of the thesis is to design and implement a communication scenario for the transport part of the network with the SRv6 protocol. Docker platform is used to create a topology with all its nodes. The VPP platform is used to enable SRv6 on top of this topology. VPP has the ability to be configured via NETCONF protocol thanks to the Honeycomb agent, which can process NETCONF messages and propagate them to the VPP configuration. This configuration is done by the program Ansible, which can send NETCONF configurations to all SR nodes with Honeycomb installed. Testing and verification of the topology with all SRv6 policies is handled by the TRex traffic generator.

System for the Protection against DoS Attacks Using IDS
Mjasojedov, Igor ; Fukač, Tomáš (oponent) ; Kučera, Jan (vedoucí práce)
This bachelor's thesis deals with the use of the Intrusion Detection System in the protection of computer networks against Denial of Service attacks. Suricata is the IDS system chosen for this purpose. The main goal of the thesis is to integrate the Suricata system with the DDoS Protector device. DDoS Protector - DCPro is a security network device, which uses, from a software perspective, DPDK technology for high-speed network traffic processing. Due to this fact, this technology was also integrated into the Suricata system. After this integration, the communication between DDoS Protector and Suricata system was allowed more easily. As a result, two DPDK compatible regimes were created in the Suricata system. The individual regime allows Suricata to process network data directly from the network interface card. The second, integrated regime allows DCPro to send network data to the Suricata system for highly precise analysis, which significantly extends DDoS Protector's attack detection abilities.
