The root cause of the routing table growth problem is that we're using the
same element (IP address) to express three distinct concepts:
1. the globally unique identity (GUID) needed by the originating client
system to find the destination server,
2. a component of the session identity (SID) used by the layer 4 and
higher protocols to keep track of communications with other hosts, and
3. the node's present location or locations (LOC) within the network
topography.
I would put it a little bit differently: The root cause is that, by the
current routing architecture, just a globally unique identity (GUID) is used
for
finding both the egress router as well as the destination server.
And also: Point 2, although true, is a different topic, but is orthogonal to
this problem.

Hi Folks,
The third draft is now available at
http://bill.herrin.us/network/rrgarchitectures.html . It adds a
strategies D, E and F to the solution universe and moves the major
criticisms of each strategy to a separate subheading so that the
criticisms don't clutter the description of the approach.
The second draft is archived at
http://bill.herrin.us/network/rrgarchitectures2.html
For the folks who offered suggestions on the earlier drafts: Thank
you. Have I addressed the issues you brought up? How can I further
improve the document?
For everyone: I'd like to close this document after this draft. If you
have any additional comments or criticism, now's the time.
Regards,
Bill Herrin
