A modified charter has been submitted for Network File System Version 4 (nfsv4) in the Transport Area of the IETF. The IESG has not made any determination as yet. The following description was submitted, and is provided for informational purposes only. Network File System Version 4 (nfsv4) ------------------------------------- Current Status: Active Working Group Description of Working Group: The objective of this working group is to advance the state of NFS technology by producing specifications to extend the original NFS Version 4 work (RFC 3010) to provide additional capabilities, as described below. o NFS version 4 Advance the protocol along the standards track, coordinating the development of test suites to provide a high level of implementation quality. The ONC RPC standards that NFSv4 references must also be advanced. This includes work to make NFSv4 and the underlying ONC RPC protocol compatible with IPv6. Specifically, we will advance RFC 3010, RFC 1831, RFC 1833 and RFC 2203 to Draft Standard. The working group will help advance related security RFCs, specifically through the definition of a method to advance APIs. o Replication and Migration The original working group defined a mechanism for NFS clients and servers to support replication and migration of data transparently to an application. Left undefined in the initial work was the server back end migration and replication mechanism. The working group will produce a draft submission of a replication/migration protocol that supports NFS Version 4 clients - needed to create and maintain replicated filesystems as well as migrating filesystems from one location to another - and servers for consideration as Proposed Standard. o Management The working group will produce a draft submission for consideration as Proposed Standard of a management MIBs to provide better management and administration capabilities for NFS and ONC RPC. o Minor Versions NFS Version 4 contains within it the capability for minor versioning. Some discussions within the working group suggest addressing additional requirements over the original charter. The WG will work to identify additional requirements for NFSv4 and determine if they are appropriate and worthwhile for a minor version. This work may lead to proposals for additional work items. If it does a specific proposal to add these work items to the charter will be forwarded to the IESG and IAB. ================================================= NEW CHARTER WORDING ADDITION: o RDMA/RDDP enabling The performance benefit of RDMA/RDDP transports in NFS-related applications, by reducing the overhead of data and metadata exchange, has been demonstrated sufficiently such that the working group will pursue in parallel enabling NFS and RPC over the transport defined by the RDDP working group. The WG will restrict its initial activities to defining the problem statement and specifying the requirements for possible extensions to RPC and NFS (in the context of a minor revision). =================================================
