Question on Tracker Inter Communication

I have been wondering on this for a long time now, can somebody please throw some light on, the inter communication between trackers.
I mean to say, for eg. some xyz.org runs its torrent trackers, and they might have 10 or 50 or 100 trackers (or is it possible a single torrent tracker can handle all the clients/peers ??),

so how do the trackers intercommunicate, transfer etc. the
1. Torrent file information
2. Peer information

Should it be time-based(i think so), will the communication between them encrypted ?
should the trackers be deployed on a special topology to improve this, might be a multicast tree or is it also possible that they can even have a class D address based on their site's request. (Anycast can also help, similar as root nameservers.)

As far as i checked, these are the lookups i found

1.Name:    tracker.something.org
Addresses:  192.121.86.7, 192.121.86.8, 192.121.86.2, 192.121.86.3
          192.121.86.4, 192.121.86.5, 192.121.86.6

2. Name:    abc.otherthing.com
Address:  62.149.24.72

Is there any specification on this, which i might have not looked or i might have overseen. There was nothing about it on the Bittorrent Protocol Specification v1.0

P.S. Is there any other Bittorent protocol specification?

P.P.S. This is a newbie question.

Re: Question on Tracker Inter Communication

There is no such specification that defines inter-tracker communication. If you have control of both servers, you could always implement some proprietary system for sharing data -- share a database, or open some API for one server to get all the data from another.
