Radha,
I think this depends somewhat on your pricing model. For
example - if it is access based - then accounting may occur at the
registry - that manages active accounts for the month / period.
If accounting occurs based on successful business transactions
completed - then it would be in the backend - when the transaction is
verified as complete. If its based on the traditional VAN model
of bytes transacted - then ESB hook makes sense.
For me - the key is to have a pluggable architecture - so its easy to
add these domain specific tools in a *consistent* way that allows
seemless re-use driven by simple XML-script / configuration
control.
This takes you away from systems of today - that have hardwired
coding everywhere - and therefore the infrastructure cannot easily be
shared, re-purposed or quickly adapted. Ease of change is
critical factor - of course anyone can change code and re-build - given
enough time, resources and testers. What we sorely need is ability
to manage and implement change easily with minimum resources.

Goran,
With reference to
versatile EBSOA gateway frame, i have some suggestion
with
reference to ESB.
Does the ESB need to have the
provision of service accounting? If not
atleast have standard
mechanism for interfacing with the other techniques
that take care
of service pricing, accounting, charging and payment.
If ESB
does not take care of it, which will take care of it?
Federation
server?
