Best Current Operational Practices - An Update Jan Žorž (Internet Society) The Internet Engineering Task Force (IETF) standardizes the protocols and services that vendors implement and network operators are supposed to deploy and use. We believe there is an opportunity to better identify, capture, and promote best current operational practices emerging from various regional network operators’ groups. We believe sharing these documents across the globe would benefit the wider Internet community and help more operators deploy new technologies like IPv6 and DNSSEC faster and easier. Deploy360’s Jan Zorz will give an update on this progress, discuss the status of BCOP efforts across the world, and give an overview of some of the documents in the process so far.

Best Current Operational Practices (BCOP) –
updates and status from around the world
DO Team – Internet Society

2. BCOP | February 2013
What’s a BCOP?
Best Current Operational Practice
•A living document describing the best
operational practices currently agreed on by
subject matter experts
•Vetted and periodically reviewed by the global
network engineering community (GNEC)

3. BCOP | February 2013
The Problem
• Operational knowledge tends to be “tribal”
• Presentations, hallway conversations, internal
documents, in someone’s head…
• Technology, tools, and practices change over time…
• There are hundreds of operational forums
globally
• Archives stored in different formats, some searchable,
rarely have speech text or video, no vetting, and state
unknown.
• How do I find up-to-date, relevant
information when I need it?

4. BCOP | February 2013
The BCOP Solution
Open, Transparent, Bottom-up, and Community led
 Community driven, community written, community vetted Best
Current Operational Practices from an open forum, list, and
publicly searchable site.
 Community written and approved Development Process for
BCOPs
 Everyone is welcome to participate
80/20 model
