One measurement tool carries the trade — the judgement reading it stays human.
The measurement layer of this role runs through Cisco IOS / Juniper Junos — The command-line operating systems powering enterprise and broadcast network infrastructure.
Doing it well
Network uptime SLAs (99.9%+), mean time to repair, security incident rate.
Ongoing monitoring with formal change review cycles. This is a role where you find out for certain whether you were right.
Myth & reality
Why it matters
Network downtime costs businesses thousands of pounds per minute. Network Engineers prevent this.
Every website you visit, every video call, every bank transaction — routes through infrastructure an engineer designed and maintains.
