APNIC Open Policy Meeting

SIG: Routing

 Minutes

    Meeting commenced: 11:10 am

    Chair: Philip Smith

Measuring BGP - Geoff Huston, Telstra

[Presentation (ppt)]

This presentation summarised an analysis of BGP table data, showing growth rates, and comparing them to global RIR allocation policies. The presentation concluded that CIDR is no longer the way the Internet is characterised in practice and that this requires development of an alternative to BGP for inter-domain routing.

Questions and discussion

There was a general discussion about whether a working group exists to look into other community-based techniques or the possible use of additional attributes in the protocol. It was noted that in practice, operators are secretive of their routing policies, which would restrict the extent to which such practices could operate.

There was general discussion about the metrics analysed in the research.

Internet Routing Table analysis update - Philip Smith, Cisco

[Presentation (ppt)]

This presentation summarised an analysis of Internet Routing Table metrics, comparing the results in the three RIRs globally. The update included additions to the study, as well as statistics on /24 announcements and announced but unassigned ASNs.

Questions and discussion

There was a question about whether highlighting network problems in this report puts peer pressure on operators to make changes. It was noted that this and the CIDR report no longer seem to exert such peer pressure.

There was also a discussion of whether there was a role for RIRs to exert pressure to ease these routing problems. It was noted that there is a justified reluctance for RIRs to become involved in policing Internet operations.

It was also suggested that the practices that are being used are actually justifiable in a business sense and that this highlights the need to re-examine allocation policy.

AS Number exhaustion - Geoff Huston, Telstra (on behalf of Scott Marcus, Genuity)

[Presentation (ppt)]

This presentation outlined the trends in AS number use, predicting ASN exhaustion in mid 2005. The presentation called on the RIRs to track this data and review policies and take other steps required to prevent future problems.

Questions and discussion

It was noted it is relatively easy to expand the ASNs from 16 bit to 32 bit, but that the real challenge is to Internet routing protocols in coping with such expansion.
