Real-Time Networking Projects
Packet-level, TAC-level, production-focused training for Core Network Engineers. 18 modules covering enterprise, data center, and SP architectures, hardware and protocol troubleshooting, P1/P2 incident handling, monitoring tools, network automation, and interview preparation.
Course Overview
At Tungabadra Networks, this packet-level, TAC-level, production-focused program covers real-world networking projects across enterprise, data center, and service provider environments. Across 18 modules you will work with multi-vendor hardware (Cisco, Juniper, Arista, Aruba), troubleshoot SFP/fiber and interface issues, debug OSPF, BGP, MPLS, and IPsec problems, perform packet captures with Wireshark, handle P1/P2 incidents with war-room communication and RCA reporting, operate monitoring and ticketing tools, and get started with network automation using Python and REST APIs. Dedicated modules guide non-IT candidates through the KT process and map out the career path to Principal Network Engineer, closing with interview preparation and resume building.
