Implementation of mechanisms providing Segment Routing for IPv6 (SRv6) using the FD.io VPP platform
Mjasojedov, Igor ; Dvořák, Jan (referee) ; Koláčková, Aneta (advisor)
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.

Integrating Real-Environment 4G and 5G Mobile Data Patterns into Network Simulations for Delay Analysis
Kolackova, Aneta ; Jerabek, Jan ; Hosek, Jiri
This article presents a simulation testbed for analyzinga mobile transport network using open-source networkingtools and protocols. The topology was designed according to the5G transport network architecture, with Segment Routing forIPv6 (SRv6) technology and The Fast Data Project Vector PacketProcessor (FD.io VPP) utilized for packet processing. The Trextraffic generator was used to simulate data transmission, andthe Docker platform enabled centralized access and managementof the topology. Real data patterns collected from one cell sitewas inserted into the created topology to create output forfuture research. The created testbed provides a valuable toolfor analyzing the mobile transport network’s performance andfuture optimizing based on needs of network slices.
