Hi Tiru,

 

It is looking good.

 

However, we are not consistent in the usage of “mitigation-start” in the signal draft and “start-time” where time is represented differently in the usage of uint64 which may cause some downstream confusion.

 

I actually prefer (the granularity of) the “start-time” format, but am unsure as to how you would define  this in YANG.

 

Regards

 

Jon

This revision https://tools.ietf.org/html/draft-reddy-dots-telemetry-02 addresses comments from Kaname, Jon, Wei Pan and Yuuhei Hayashi.  

 

Major changes are listed below:

 

a.  Added path-suffix ‘telemetry’ to from the URI to signal DOTS telemetry

b.  Added attributes useful to detect resource-based DDoS attacks

c.  Attack details can be signaled from the DOTS client to server and vice-versa. 

d.  Added several new attributes for attack details including top talkers.

  

Comments and suggestions are welcome.

Abstract:
   This document aims to enrich DOTS signal channel protocol with
   various telemetry attributes allowing optimal DDoS attack mitigation.
   This document specifies the normal traffic baseline and attack
   traffic telemetry attributes a DOTS client can convey to its DOTS
   server in the mitigation request, the mitigation status telemetry
   attributes a DOTS server can communicate to a DOTS client, and the
   mitigation efficacy telemetry attributes a DOTS client can
   communicate to a DOTS server.  The telemetry attributes can assist
   the mitigator to choose the DDoS mitigation techniques and perform
   optimal DDoS attack mitigation.




Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
