Re: [OPSAWG] [OPS-AREA] Present day reality of COPS-PR

Appreciate the investigation, but also agree it needs to be vetted (academic versus real world deployments). 
For example...
- AFAIK COPS, not COPS-PR, is used for DOCSIS/PacketCable DQoS. Hope the rest of the list correctly makes this distinction. 
- I've not been able to locate any open source community
- I've located a single vendor, Trillium, that offers support (embedded in an IMS suite). 
- the word from my colleagues @ Cisco is that its time has passed.
- etc.

Its pretty clear its not massively deployed.

We can write a short cal for input about implementations and deployments

in OPSAWG. Certainly such input may also arrive at the time of the IETF
LC but it would be better to know about it earlier.

Hi,
These claims were gathered by me from co-workers familiar with COPS-PR. 
I have not checked any of the claims.
The most interesting to me are the claims of deployment in FIOS, FT-Orange, and Comcast. We should seek out people knowledgeable about the technologies used in these networks, and ask about COPS-PR. Does anybody have contacts within the IT departments of these companies?

- there are few, if any, significant deployments.

AFAIK, there is minimal commercial or open source support.
I have not been able to research these claims, but I am told that COPS-PR is actually in use in a number of places. Here
are some of 
the claims I have heard:
1) Juniper uses COPS-PR for their resource allocation, using both push and pull methods, at least in the access and aggregation network. 2) COPS-PR may be deployed in the Verizon FIOS (FTTH)
access network 
in the US.
3) COPS-PR may be deployed in the FT-Orange IPTV access

network in UK.
4) Comcast uses a mix of COPS and COPS-PR in cable TV video QoS control. 5) COPS-PR is in DOCSIS 1.0 QoS, which may still be used in cable deployments 6) Huawei uses both COPS and COPS-PR in their Quidway RM9000 Resource Manager and their Multi-Service Control Gateway solution (public documents show COPS, but I have not found
explicit mention 
of COPS-PR; I am checking further)
7) ITU-T has a proposal being considered that is based on COPS-PR
Searching the Web I found some additional information that might bear further research (many items have no associated dates): 8) MultiService Forum has an Implementation Agreement for Dynamic Policy Control Using COPS-PR (2005) 


http://www.msforum.org/techinfo/approved/MSF-IA-COPS-PR.001-FINAL.pdf
9) IEEE Xplore has a paper that apparently was presented
at ICT 2008 
comparing the performance of COPS-PR and Netconf.
The paper might identify some equipment that has COPS-PR support.
10) A 2006 paper was published in the Proceedings of the IEEE International Workshop on Policies for Distributed Systems and Networks. The paper considers substituting Netconf and/or
SOAP for 
COPS-PR
11) I found discussion of COPS-PR in JUNOSe and the SAE
on the web,
apparently for the SDX line (dated 2008). Was this from
the Juniper 
acquisition of netscreen and neoteris?
12) Sejong University apparently has developed a COPS-PR lite


http://ietcom.oxfordjournals.org/cgi/content/abstract/E90-B/11/3024

13) EION has an implementation
http://www.eion.com/protocols/protocols_traffic_cops.html
14) Cisco Catalyst has an implementation
15) Wireshark apparently implements it
16) ACSE Networks implements COPS-PR in their NeuTrans product

line

17) ZNYX Networks implements COPS-PR in the ZX4900
18) libsmi implemented it
19) Operax AB implemented it
20) MIB Smithy implemented it
21) GridNet has implemented it in its products for managing

utility

(power) grids
22) GE apparently embeds the GridNet implementation in its WiMax SmartMeter and SmartGrid Router family of products 23) COPS-PR has been the subject of a tremendous number
of academic 
papers
There claims need to be examined carefully. We need to
differentiate
between academic papers, code implementation and deployment. It is probably true that a number of open source packages and tools implemented COPS-PR after it was put on standards track, but the question is to what extent this code was also used and deployed. 
Same
for the vendors implementations - was COPS-PR deployed and how? In the absence of standards PIBs I suspect that the majority
or all the
deployments use one vendor tools and agents, but we need to give enough time for these vendors to step ahead and explain in case interoperability is impacted by the proposed standards action.
