Abstract

U ovom radu je provedena analiza SDH mreže Hrvatskih željeznica s obzirom na rasprostanjenost uređaja i servisa koji se koriste. Analizirani su servisi i kofiguracija mrežnih uređaja i na osnovu toga je dan prijedlog optimizacije i rekonfiguracije SDH optičke mreže. U radu su prikazane metode nadzora, dokumentiranja i rješavanja incidenata koji se prate pomoću programa TNMS. Također je prikazana integracija s budućim krovnim incident management programima koji će se koristiti u sklopu uvođenja sustava upravljanja imovinom. U početnom dijelu rada prikazane su PDH i SDH prijenosne tehnologije. Kronološki je prikazan razvoj SDH mreže od početaka ugradnje (2006. godina) do danas kao i migracija s tradicionalnih servisa (E1) na Ethernet povezivanje. Prikazane se metode redundancije koje se mogu koristiti obzirom na specifične uvjete. Objašnjen je sustav za nadzor i upravljanje SDH mreže – TNMS i opisane su najčešće korištene procedure prilikom svakodnevnog korištenja. Na kraju su predložene i opisane sve metode redundancije koje se mogu primijeniti u SDH mreži Hrvatskih željeznica.

Abstract (english)

This work analyzes SDH network of the Croatian Railways with regard to the spread of the devices and services used. Services and configuration of network devices have been analyzed and on this basis it is proposed optimization and reconfiguration of the SDH optical network. This paper presents the methods of monitoring, documenting and resolving the incidents that are monitored by the TNMS program. It also shows integration with future incident management programs that will be used as part of the introduction of asset management system. PDH and SDH transmission technology are shown in the beginning of the work. The SDH network development from the beginning of the installation (2006) to date as well as the migration from the traditional service (E1) to the Ethernet link is chronologically presented. Redundancy methods that can be used in terms of specific conditions are shown. The SDH Network Monitoring and Management System (TNMS) is described and the most frequently used procedures are described for everyday use. Finally, all redundancy methods that can be applied in the SDH network of Croatian Railways are suggested and described.
