[Cz-computers] Multihoming and BGP articles

I wanted to draw your attention to some related articles on which I'm
working, get suggestions, check to see that I'm not violating any conflict
of interest policies, and perhaps get better ways to arrange some articles
and subpages.

 

The most general article is "multihoming". The article is drawn from a 1999
draft for the Internet Engineering Task Force, which did go through two
rounds of review but didn't fit into a specific workgroup and never went to
RFC.  I may yet revive it, given that it looks at multihoming at all
protocol layers, when the current IETF work on multihoming deals mostly with
IPv6, including some unsolved problems.   With the CZ article, you'll see a
table of multihoming methods at various protocol levels, and I propose to
link to a number of subarticles doing multihoming using means as diverse as
transaction-level load distribution, intelligent DNS, 802.3ad link
aggregation, multilink PPP, SONET and Next Generation SONET, Resilient
Packet Rings, etc.

 

As you presumably know, I've started a BGP article. It has several subpages,
and I'm not convinced that these should be subpages rather than subarticles,
if for no other reason that it appears to be harder to wikilink to a subpage
than a subarticle.  Now, I will cite some BGP (and also OSPF) multihoming
techniques that I and others have presented at the IETF and NANOG, as well
as possibly using examples from two of my books, WAN Survival Guide and
Building Service Provider Networks, both from Wiley. Believe me, the sales
on these have not been such that I expect any knowledge to produce any
money!  While I'm certaiinly open to using examples from other BGP books
such as Parkhurst and Halabi, the problem is that to the best of my
knowledge, mine are the only ones, which were reviewed by independent
experts working with the publisher, that are not vendor-specific. There are
a number of Cisco BGP books, but they tend to focus more on the nuances of
Cisco configuration (of which there are many), rather than an exhaustive
coverage of the scenarios that can be covered by BGP multihoming.

 

Anyway, feedback on this material would be greatly appreciated.
