Australian carrier Optus has validated Cisco's Live Protect technology on Cisco 8000 Series routers, making it the first telecommunications provider globally to do so. The validation follows earlier work on Cisco Nexus 9000 Series switches running in production environments.
Why it matters
Live Protect lets operators deploy targeted protections without restarting affected equipment, while permanent software fixes are still being tested. The validation is part of Optus' wider IP network modernisation partnership with Cisco, which covers 5G, spectrum, AI and automation.
The validation is documented as a first-of-its-kind deployment for a telecommunications provider on Cisco 8000 Series routers. The extraction does not provide device counts, performance metrics, or a timeline for the NCS Series extension.
The players
Optus
Optus is an Australian telecommunications carrier and a subsidiary of Singapore Telecommunications Limited.
Cisco Systems
Cisco Systems is a multinational networking hardware and software company headquartered in San Jose, California.
The details
Live Protect applies targeted protections to network equipment without requiring a restart, separating the deployment of a control from the permanent update validation process. Optus validated the technology to push protective measures across its network faster while keeping existing testing and change management processes intact.
Timeline
November 8, 2026: Optus validation of Cisco Live Protect announced.
Past year: Optus network modernisation focused on 5G, spectrum, AI and automation.
Next phase (date not specified): Validation expected to extend to Cisco NCS Series routers.
Tech Race
Live Protect's move from Nexus 9000 switches to Cisco 8000 Series routers at Optus marks an extension of the technology from data-centre style switching into carrier-grade core routing. The next step to NCS Series routers would widen its use across Cisco's service-provider lineup.
For customers of Optus, faster deployment of protective measures could mean fewer prolonged network disruptions when vulnerabilities are found. The change keeps existing testing and change-management controls, so reliability safeguards are not reduced.
The takeaway
Carrier networks can now apply protective fixes faster without sacrificing the testing that keeps services stable. Watch for Live Protect's expansion to NCS Series routers as a sign of how far the approach will spread across service-provider networks.
What happens next
Optus and Cisco are expected to extend Live Protect validation to Cisco NCS Series routers, with the next phase aimed at reducing manual deployment steps while keeping operational controls. No date for that phase was given.
