ipnc (Inter-Provider Notification Channel)

CAIDA provides a jabber channel for use as an inter-provider notification vehicle, including for real-time interaction during diagnosis and repair of network problems. This jabber channel has access restrictions to encourage providers to share technical information, framed by the assumption that regular sharing of engineering information on externally visible problems/maintenance will lead to a more stable, healthier Internet.

For details on jabber and clients, consult

Joining CAIDA's ipn conference channel on jabber

For instructions on how to get on CAIDA's IPN jabber channels, see the steps in How to connect to a CAIDA jabber server, specifically joining the "ipn" conference room with, which would be a visible chatroom during the step at Service Discovery / Joining a room.

About ipnc

Providers have expressed concern that their outage/maintenance information could be used by competitors to gain an advantage. The below terms attempt to limit misuse of outage/maintenance engineering information.

  • ISP agrees to make good-faith effort to share scheduled maintenance and ongoing outage information. The primary focus of the tool is the communication of major outages/maintenance visible to other Internet providers.
  • ISP agrees not to redistribute IPNC information and to use the information for the sole purposes of operations/network management.
  • If a majority of IPNC participants believe a provider has not acted in good-faith with regards to the above criteria, the majority can elect to exclude that provider from the IPNC.

CAIDA (Cooperative Association for Internet Data Analysis) is a proposed effort to promote greater industry cooperation in architecting and managing the Internet. It seeks to address global engineering concerns that are highly dependent on cross-ISP coordination. This includes efforts to:

  1. identify, develop and deploy measurement tools across the Internet;
  2. work with commercial providers to provide them with a neutral, confidential vehicle for data sharing and analysis;
  3. provide networking researchers and the general Internet community with current data on Internet traffic flow patterns;
  4. assist in the introduction / deployment of emerging internet technologies such as multicast, IP v.6, web caching, bandwidth reservation protocols, etc.; and
  5. enhance communications among commercial Internet service providers and the broader Internet communities.
