Hi there,

An observation

#2 Page 8  "Filter management, which enables a DOTS client to install or
      remove traffic filters dropping or rate-limiting unwanted traffic."

Why would be the client installing / removing traffic filters (presumably instructed by the DOTS server) when help is needed from upstream?
- It is possible that the DDOS client will be doing its own local mitigation (and hence traffic filters), but that is separate from getting help from the DOTS server.

"Filter management, which enables a DOTS client to inform the DOTS server about possible installation or
      removal of traffic filters dropping or rate-limiting unwanted traffic."

Regards

Jon
