OK, I got it. Actually, we pay attention to two point:
1. Which method will be more nicety? In RFC6976, all devices in network need calculate the schedule time, base on the different hardware and environment, we worry about its effect. In our draft, only failure point adjust the cost, the other device just response the cost change. I think the effect of this kind of difference will be less. 2. Due to no new extension, maybe the distribution will be more smoothly. -----邮件原件----- 发件人: Acee Lindem [mailto:[email protected]] 发送时间: 2013年10月22日 9:42 收件人: Yangang 抄送: [email protected]; Zhangxudong (zhangxudong, VRP) 主题: Re: 答复: Soliciting WG feedback and comments on draft-zxd-rtgwg-ordered-metric-adjustment-00 I'm aware of the basic premise of the two drafts and was not asking for you to restate the obvious. Specifically, what are the benefits and determents of your draft when compared to RFC 6976?
