Appeal No. 1997-1184
Application No. 08/206,706
Claim 1 is illustrative of the claimed invention, and it
reads as follows:
1. A method of managing a file system cache in a client
computer system operating under a first operating system, the
method comprising the steps of:
intercepting operating system requests for a file system
object in a distributed file system;
transforming said requests to remove operating system
dependent syntax;
testing a cache in a storage means of said client for the
presence of file system object data based on said transformed
request;
satisfying said transformed request for said file system
object data, if cache data exists[;]
testing to determine whether a connection exists to said
distributed file system;
generating a request for said file system object from
said distributed file system, without regard to distributed
file system protocol, if no cache data exists and there is a
connection;
transmitting said request to said distributed file
system; and
rejecting said file system object request, if no cache
data exists and there is no connection.
