Title : AFSVol Tag-Length-Value Remote Procedure Call Extensions
Author(s) : T. Keiser, S. Jenkins
Filename : draft-tkeiser-afs3-volser-tlv-00.txt
Pages : 27
Date : 2009-11-16
AFS-3 heavily leverages Remote Procedure Calls (RPCs). This proposal
adds a new mechanism to better manage the addition of new,
enhancement-specific RPCs through the use of both capability bits via
the GetCapabilities RPC, and via standardization of backwards-
compatibility behaviors for enhancement-specific RPCs. These goals
are accomplished through standardization of Tag-Length-Value (TLV)
get/set/enumerate RPCs with value payloads encoded using an XDR
discriminated union. The XDR union decode problem is circumvented by
specifying an opaque default leg. Tags are allocated for existing
volume and transaction metadata, and implementation-private tags are
allocated for metadata related to the OpenAFS Demand Attach File
Server.
