“…CANARIE infrastructure supports nowadays more than 400 PB by year interconnecting their 770 national institutions to 125 NRENs in 100 countries [1][2][3][4][5][6]. Because GNS3 supports backbone routers, in previous works this emulator was used to study other backbone topologies but specifically the CANARIE for Canada one under IPv4, when all the thirteen provinces and territories were not covered, just only 12 of them, using 25 backbone routers in its topology [7]. It was in august 2020 when Nunavut Territory was included adding the first corresponding infrastructure to make reality the Canadian dream of offering a pan-Canadian advanced network after 27 years it was founded [8].…”

The National Research and Education Networks or Advanced Networks implemented in all countries in the world are the alternative Internet to the commercial Internet which was developed for education and experimental purposes beginning with the Internet 2. Our interest is to study the CANARIE topology after 27 years of the foundation of the pan-Canadian advanced network which now interconnects all the thirteen provinces and territories in the country. In this work a connectivity and management emulation for the updated 2022 backbone topology of CANARIE was developed under IPv6 protocols. So, emulator GNS3, Wireshark, iReasoning MIB browser, Virtual Box and Kali Linux were required to emulated CANARIE backbone infrastructure using the best possible approximation with the available resources, considering that real infrastructure is overly expensive and just supported by internet service providers. Results were successful for connectivity and management tests, showing no significative changes when Canada expanded its advanced network. Emulation uses a lot of CPU and RAM resources, but it also shows some limitations for GNS3 when comparing to real bandwidth scenarios. CANARIE maintains important connections to support international projects with other advanced networks GEANT in Europe, APAN in Asia, AFRICACONNECT through GEANT and CLARA in Latin America through Internet2 in USA. Emulating is the alternative for backbone networks for characterizing advanced networks around the world which uses expensive equipment only available by the Internet Service Provider companies.
