Understanding the NetWare Client Software
The NetWare DOS Requester Architecture
Transport Protocol Layer
This layer is responsible for maintaining connections, providing packet
transmissions between connections and performing other transport-specific
functions.
The IPXNCP module uses the IPX™ protocol as a transport mechanism.
The AUTO.VLM module reconnects a client workstation to a server and
rebuilds the workstation’s environment—excluding file-specific items—to
its original state prior to losing connection.
Communication and Connection Management
The NetWare DOS Requester contains communication and connection
management for controlling the NetWare client software.
VLM Manager
The VLM Manager (VLM.EXE) controls communication and memory
issues between the individual VLM software programs. It is responsible for
loading the required modules and disbursing requests to individual modules.
Therefore, instead of loading NETX, EMSNETX, XMSNETX, or BNETX,
the user loads only the VLM.EXE program.
The VLM Manager decides whether a given VLM program uses expanded
memory, extended memory, conventional memory, or any other memory
type supported, without affecting the individual VLM programs.
Connection Table Manager
The Connection Table Manager (CONN.VLM) spans all the layers of the
NetWare DOS Requester architecture.
CONN allows client workstations running the NetWare DOS Requester to
establish a configurable number of connections with multiple NetWare
servers.
