Technical Summary
This document specifies how to use DNS (Domain Name Service) SRV RRs
(Resource Records) to locate services for the AFS distributed file
system and how the priority and weight values of the SRV RR should be
interpreted in the server ranking system used by AFS. It deprecates
use of the AFSDB RR to locate AFS cell database servers and provides
guidance for backward compatibility.
Working Group Summary
This is not a WG document.
This document represents the consensus of the AFS community to
deprecate the use of DNS AFSDB resource records to locate AFS
database services, as described in RFC1183, in favor of using SRV
records. While the AFS protocols themselves are not the subject
of any IETF work, this document is being advanced via the IETF
because it updates previous IETF extensions to the DNS.
Document Quality
Major AFS client implementors have indicated plans to implement
support for use of SRV records as described by this document.
In addition, a variety of developers and operators have indicated
a desire to publish and use SRV records as described here. There
was substantial discussion surrounding the mapping of weight and
priority information advertised via these records onto the server
ranking system used by current AFS implementations, which resulted
in the advice given in section 4.1.
