Re: [OSPF] OSPF Topology Transparent Zone (TTZ) WG Poll for Adoption as Experimental

I was a member of a team on vendor side for dividing a network with only area 0 into a few of areas. The team spent a long time (1+ years) in splitting the network into multiple areas in order to have minimum service interruptions.

OSPF Topology Transparent Zone (TTZ) provides an easy way to transfer a part of network in an area into a zone smoothly without service interruptions. In a few simple steps, a part of network is transferred into a zone smoothly. The zone also makes the LSDB become smaller. These have been demonstrated live. 

So I support it for WG adoption.

We have discussed OSPF TTZ at several IETFs and the authors and their colleagues have even developed a working prototype. We believe there is consensus that the protocol mechanisms are viable. However, there is disagreement as to whether or not these mechanisms will provide significant benefit. The answer is definitely topology and deployment dependent. After some discussion, we have decided to poll for adoption as an experimental draft. Please indicate your support or opposition WG adoption as experimental prior to January 24th, 2015.

For your convenience, here is a URL for the draft:
