I read this documents. I think this draft would be useful to consider CGP deployment for service providers.
And I have question. http://tools.ietf.org/html/draft-nishizuka-cgn-deployment-considerations-00#section-4 Figure 1: The number of sessions of applications. Q.Which browser did you use in your investigation? Our investigation shows that the average number of session of active subscriber is 400. Q.Can you show more detail information? The investigation in the commercial network? or test bed? http://tools.ietf.org/html/draft-nishizuka-cgn-deployment-considerations-00#section-5.2 (a) was estimated to be 25% at the value during the busy hour of traffic (21:00 pm to 1:00am). Q.Does the estimation come from your investigation on real network? or erlang and someting? What kind of network?Wireless or Wireline?IPv6 enabled network? http://tools.ietf.org/html/draft-nishizuka-cgn-deployment-considerations-00#section-6.1 Q.Is current RFC not enough to measure CGN performance? RFC 3511 Benchmarking Methodology for Firewall Performance http://tools.ietf.org/html/rfc3511 RFC6645 IP Flow Information Accounting and Export Benchmarking Methodology http://tools.ietf.org/html/rfc6645 Regards, -Shishio -------- Original Message -------- Subject: I-D Action: draft-nishizuka-cgn-deployment-considerations-00.txt Date: Thu, 28 Mar 2013 07:12:24 -0700 From: <[email protected]> Reply-To: <[email protected]> To: <[email protected]> A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : Carrier-Grade-NAT (CGN) Deployment Considerations. Author(s) : Kaname Nishizuka Filename : draft-nishizuka-cgn-deployment-considerations-00.txt Pages : 16 Date : 2013-03-28 Abstract: This document provides deployment considerations for Carrier-Grade- NAT (CGN) based on the verification result include the investigation of the number of sessions of applications. The verification was conducted in StarBED which is one of the largest scale network experiment environment in Japan. A million of subscribers was emulated and it revealed the realistic behavior of CGN.
