Hi Gunter, We collect the requirements from our customers. Actually traditional ACLs already support similar functions. For the last sentence, could you please explain a little more? Why do you think it is complex? Thanks, Jianjie 发件人: Gunter Van De Velde [mailto:guntervandeveldecc@icloud.com] 发送时间: 2015年10月19日 15:32 收件人: Youjianjie 抄送: idr@ietf.org 主题: Re: [Idr] New Version Notification for draft-liang-idr-bgp-flowspec-time-00.txt Hi Youjianjie, I would expect a flow spec rule to be valid for consumption from the moment its originated from a flow spec controller until it is withdrawn by the controller. In the text proposed you relate to different forwarding delays for a router to receive the flow spec rule and hence justifies a need for new community to specify 'valid-time' for the flow spec route. This seems as a pretty light reason for such a complex proposed logical machine. Be well, G/ Sent from iCloud On Oct 19, 2015, at 04:08 AM, Youjianjie <youjianjie@huawei.com<mailto:youjianjie@huawei.com>> wrote: Dear all, This document proposes a new BGP path attribute called "Flow Extended Attribute", which carries expected valid period information for a FlowSpec rule.

Name: draft-liang-idr-bgp-flowspec-time Revision: 00 Title: BGP FlowSpec with Time Constraints Document date: 2015-10-18 Group: Individual Submission Pages: 9 URL: https://www.ietf.org/internet-drafts/draft-liang-idr-bgp-flowspec-time-00.txt Status: https://datatracker.ietf.org/doc/draft-liang-idr-bgp-flowspec-time/ Htmlized: https://tools.ietf.org/html/draft-liang-idr-bgp-flowspec-time-00 Abstract: The BGP flow specification (FlowSpec) is an additional tool to mitigate the effects of Distributed Denial of Service (DDoS) attacks. Since DDoS attacks are dynamic, filtering of a flow may only be necessary for some specified time, and be undesirable at other times. This document proposes a new BGP path attribute called "Flow Extended Attribute", which carries expected valid period information for a FlowSpec rule. So network administrators can control certain types of traffic in a specified period. 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.
