Policies from experience

[Djamel Sadok <jamel () cin ufpe br>]

Hi everyone,

I am curious regarding the use of "policies", rules or goals to manage a
network at the three levels: business, traffic engineering and routing. I
have these questions:

1) What examples of policies could be enforced at each level? (the simplest
case being that of routing policies using EGP that I can think of)?

2) Could there be a clear cut in terms of policies between these three
levels: business, routing and TE ?

3) anyone using the Routing Policy Specification Language (RPSL) ?

Thank you for taking the time.
