Tiivistelmä
During the recent years, utilizing programmable APIs and YANG data model for service configuration and monitoring of TCP/IP open network devices from a centralized network management system as an alternative to SNMP based network management solutions has gained popularity among service providers and network engineers.
However, both SNMP and YANG lacks any data model for tracing the routes between different routers inside and outside the network that has not addressed. Having a centralized traceroute tool provides a central troubleshooting point in the network. And rather than having to individually connect to each router terminal, traceroute can be invoked remotely on different routers. And the responses can be collected on the network management system.
The aim of this thesis is to develop a centralized traceroute tool called Trace that invokes traceroute CLI tool with a unique syntax from a centralized network management system on a TCP/IP router, traces the hops and BGP AS and measures RTT between a router and specific destination and returns the response back to the network management system. And evaluates the possibility of utilizing this traceroute tool along with YANG based network management solutions.
This implementation has shown that YANG based data models enables a unique syntax on the network management system for invoking traceroute command on different TCP/IP devices. This unique syntax can be used to invoke the traceroute CLI command on the routers with the different operating systems. And the evaluation has shown that using NETCONF as an API between the network management system and the network devices, enables the Trace to be utilized in YANG and NETCONF based network management solutions.
