Hi Hannes, Thanks for your comments! See my responses in line below. Best Regards, Huaimo -----Original Message----- From: ospf-bounces@ietf.org [mailto:ospf-bounces@ietf.org] On Behalf Of Hannes Gredler Sent: Tuesday, July 09, 2013 1:21 PM To: Acee Lindem Cc: OSPF List Subject: Re: [OSPF] OSPF Topology Transparent Zone (TTZ) Next Steps scaling a link-state protocols route-calculation path (SPF and RIB-Walk) to support 1000s of nodes is an already solved problem. solving it again, (just different this time) is of limited use ... [Huaimo] How about 10,000s or 100,000s of nodes? quite contrary - i fail to see how *hiding* information (i.e. nodes and links along with their TE attributes) does not break some of the TE eco-system that has been built around link-state IGPs. i am particularly interested how TE use-cases requiring admission-control and pre-emption play with TTZ. [Huaimo] Regarding to TE, we are working on it and have some solutions. /hannes On Jul 6, 2013, at 9:09 PM, Acee Lindem wrote: > As WG chair, I'd like to initiate a discussion on this technology.
