Network dementia. The bane of aging networks!
It begins innocently enough with a few seemingly lost packets.
But it slowly becomes more intense - TCP connections begin to stall. Eventually TCP connections start to fail.
To the uneducated eye this might be diagnosed packet loss due to normal burst congestion.
But without early diagnosis and proper treatment network dementia can intensify; packets simply lose their way and end up filling circuits, switches, routers, and server interfaces. Eventually the condition will become catastrophic, the affected network will collapse in a sudden flood of aimlessly wandering packets.
Can anything be done?
