What happens when network services are requested by a workstation.
At the workstation we have the following levels to enable communication:
Application or program being used
needs something from the Fileserver or
some other component of the network
(e.g. printing) and this request is passed
on to Netware Dos Requester
Netware Dos Requester (NETX or VLM)
decides if the request is a DOS
request and passes it to DOS if it is,
otherwise it passes it to the
Communication Layer.
Communication Layer
This layer breaks the data into packets attaches
the address of the receiver and sender, and
passes it onto the Network Interface Card
Driver. This is the layer where the IPX.COM
(or IPXODI.COM) program operates (amongst
others).
Network Interface Card Driver
converts the data to a form that can be placed
on the network cabling and sends the data.
The reverse happens when communication arrives at a networked computer. |
