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 updates RFC 1183 to deprecate use of the AFSDB RR to locate AFS cell database servers and provides guidance for backward compatibility. Internet Draft Comments Comments are solicited. Please include the AFS Standardization mailing list at afs3-standardization@openafs.org as a recipient of any comments.
