Abstract

An improved file system apparatus and method for minimizing the length of time a client system waits before declaring a data communication link disconnected. The apparatus and method dynamically modify a file system request time-out value based on the actual length of time required to service each file system request. In one embodiment, a time-out value is determined for each request type based on the actual response time and a buffer time for each request type. The response timer is based on readings from a system clock therefore operating as a low overhead process. A monitoring system periodically tests the server to ensure that a physical connection still exists.
