• DSBackground daemon, which performs asynchronous background tasks, such
as synchronization, for NDS

NetWare DOS Requester
The DOS client software portion of NetWare Services. The Requester can be
called by applications or utilities in one of three ways:
• Before DOS, in the same way as the old NETX shell.
• By DOS, through the INT 2Fh redirector.
• Bypassing DOS, through a pipeline between the shell and post-DOS portions.
VLMs
The NetWare DOS Requester is composed of a number of modules called
Virtual Loadable Modules (VLMs). These VLMs are the key to the NetWare
DOS Requester’s modularity. (See “Virtual Loadable Module (VLM).”)
The Requester contains categories of services and platforms in the following
three layers:
• DOS Redirection Layer
• Service Protocol Layer
• Transport Protocol Layer
The following figure shows how these layers and modules fit together.
