RE: COPS vs. SNMP
Thanks for tracking the COPS activity in the IETF.
Within the RAP wg, the COPS base protocol, and the
extensions - COPS for RSVP and COPS-PR have been RFC'ed.
These are RFC 2748, 2749 and 3084 respectively.
SPPI describes the PIB language spec which
is one of the data models COPS-PR can carry. This
is described in RFC 3159.
Regarding COPS-PR features, some important notions are
described in the COPS-PR RFC 3084 in Section 1.1.
Also, David Harrington sent this info on the list a few days
back - Erik Liden and Anders Torger wrote a master's thesis
in January 2000 on the "Implementation and Evaluation of the
Common Open Policy Service (COPS) Protocol and its use for
Policy Provisioning" that you might want to review.
Its at http://extwww.lulea.trab.se/cops/
Intel has an open source COPS Client SDK for the above
specifications at http://www.intel.com/labs/manage/cops/
There will be an update soon that will include a client side
PIB Control Interface Generator.
Hope that helps.

Subject: COPS vs. SNMP
We have been following the IETF activities concerning the ongoing work in
the fields of SNMP and COPS. It seems that at the meeting in March 2000 in
Adelaide, the snmpconf working group was formed for issues dealing with
policy-based network management after the BOF about network management in
Dec 1999. However, now the group seems to have accomplished its charter and
finished. Does this mean that the discussion has been resolved?
We would like to know if the resource reservation in a network can/should be
achieved via COPS? If yes, how is it advantageous over SNMP?
Any help will be appreciated!
Thanks in advance,
