I'd like to get some advice on most-desired content, along with some structural suggestions (e.g., subpage vs subarticle) and also some reality checks on conflict of interest.

As some of you know, I have the start of an article on BGP. Partially to experiment with subpages in general, I created some tabs for "advanced" topics (principally scaling issues) and "operational" issues (more a matter of getting AS numbers, address space, and recording routing policies).

Now, I've created a basic article on multihoming. It's a subset of a working draft I did in the Internet Engineering Task Force; it did go through two rounds of peer comment, but, at the time, there was no good match with a Working Group to take it on, and I let it slide as a potential informational RFC. Since then, I wrote two more books on BGP-oriented network design, published, with technical review, by John Wiley & Sons. There are a number of books around on BGP, but they are mostly vendor-specific (Cisco and a bit of Juniper).  I'm not actively trying to market the books; I'd want to update them and it simply may not be a commercially viable matter to do vendor-independent, certification-independent networking books.

I would, however, like to do several articles on multihoming, and the article I put up should convey that multihoming, when done for fault tolerance and also QoS/traffic engineering, can happen at many layers; routing is important but by no means the only way to do it. There are, for example, various intelligent DNS and TCP redirectors that can spread transactions over servers.

So, whether subpages or not, I'd like to do a series of articles. Both in my book Building Service Provider Networks and in some consulting I did later, there are a good dozen different multihoming strategies. In articles here, I'd like to stress the nature of the problem being solved, perhaps routing policy logic to solve it, pros and cons of various techniques, but not how to do it on a specific router.

Yes, with all due modesty, I've published and presented quite a bit in this area, including peer-reviewed RFCs.

So -- any feedback on what is appropriate for me to do, the level of detail, whether to refer to public or at least published work I've done, etc.?

Incidentally, I tried to send this to the mailing list but I don't think it got out.

Prime Minister, you can't take the bull by the horns if you're grasping the nettle. I mean, if you grasped the nettle with one hand, you could take the bull by one horn with the other hand, but not by both horns because your hand wouldn't be big enough, and if you took a bull by only one horn it would be rather dangerous because...'
