AARNet is the Australian equivalent of North American Internet2. This was a staff profile in one of their newsletter and gives a glimpse as to which platform is the future of global networking:

"Staff Profile – Glen Turner

Glen Turner has worked as a Network Engineer for AARNet for six years and still finds it an exciting job. According to Glen, “There’s nothing quite like the stress of repairing a network which
has fallen over, nor the satisfaction when the fault has been found and fixed. Programming routers is akin to programming assembler, an intellectually satisfying task requiring accurate control of detail. By contrast, replacing routers is a highly physical task which resembles DIY construction.” Along with his colleagues, Glen is currently replacing the fine but orphaned Procket 8812 core routers with Juniper M320 core routers. They have maintained the headlong pace of replacing one router a week.

Glen is a team player and was very impressed by his colleague’s response when a minor configuration error on the core routers exposed a fault in the Cisco 7304 edge routers which caused the edge routers to lock up. This is a serious fault: it would have halted the core router replacement if it was not diagnosed and a work-around developed. It took three days for Glen and his co-workers to find the cause of the fault, determine a workaround and arrange for Cisco to fix the bug. “That’s an astonishing performance and I feel awed to work alongside such people” said Glen."
