RE: OPES protocols ?

Now what about rules loading? Are the rules loaded onto 
Admin box first and compile into internal representation 
before shipping to OPES box (in binary format)? 
Or should it be loaded onto OPES box directly via XML format?
Does it matter at all which model we choose? In first 
model, Admin box from Company A then would not be able to 
talk to OPES box from company B.

Why not? IRML defines an open standard format for exchanging 
rule sets 
- that's the purpose of IRML. Company A and company B both 
suport IRML 
- no problem for exchanging rule sets.

So to achieve interoperability, either we stick with the second 
model, or we define a standardized binary format. I would vote for 
the second model then.

Ship it to the OPES box using IRML. I can't see the need for an 
additional, redundant binary format for the same purpose (i.e. 
exchange of rule sets).

BTW - won't it be likely that the Admin "box" and the OPES "box" are 
physically on the same appliance? Why should rules first be shiped to 
some Admin box, getting validate and then being shipped to the OPES 
box? Distribute the rules sets right away to the OPES boxes and let 
them do the checking etc.

IRML allows the support of both model, either ship the modules to targeted 
OPES boxes directly are ship the module to an admin box which in
turn will ship it to the edges it knows of. That under the control of the 
box owner. And that's fine to start with.

But if I operate a CDN with a number of deployed OPES boxes and 
send the rules to these boxes so they're compiled into a rule base do I 
create myself a deployment headache ? Rules will need to be compiled, 
checked, validated, etc. all of these far from where I control my network. 
I think that down the road having a binary format could facilitate 
operation & deployment.
