clean pipe
jargonsecurityISP & telecom
Internet transit that arrives already scrubbed of DDoS traffic - the provider filters the flood upstream and delivers only the clean flow.
Sold by carriers and mitigation providers as a service: attack traffic is absorbed in their scrubbing centers, close to its sources, instead of saturating the customer's last mile. The metaphor is exact - the pipe is the same, the water is filtered before it reaches you.
Also known as: clean pipes, scrubbed transit
