[secdir] [New-work] WG Review: Network File System Version 4 (nfsv4)(fwd)

[Bernard Aboba <aboba@internaut.com>]

Presumably, this new charter element is being put in to help NFSv4 scale
to higher speeds (1+ Gbps). However, as part of this it will also probably
be necessary to do some new security work; GSS-API based security should
not be expected to scale to those kind of speeds (particularly since it
won't be supported on the contemplated RNICs, which will most likely
support IPsec acceleration instead).


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).
