Re: [WG-BB] Study Report: CATV assignment guidline

[Takashi Arano <arano@gblx.ad.jp>]

Obata-san,

NICs are recognizing CATV/ADSL needs. That is why this WG has been created.
We have got a lot of comments by now, and I do believe this is the stage
to compile these comments and get the concrete guideline approved.

Regards,
Arano

However, it is becoming more and more difficult to give rationals to network topology changes since the NIC people never understand how tough it is to move thousands of IP addresses from one BRAS to another very frequently just to manage the growth.

I think it is time to tell the truth and find some solutions before the technicians dealing the protocol between NICs and service operators get exhausted of exchanging excuses.
