This resource model should be distributed to Windows NT endpoints. |
The Network Interface Card resource model highlights the following problems:
If too much of the network is broadcast frames for an extended period of time, the network administrator should segment the network further or redesign the network to use fewer broadcast frames.
The core of the network subsystem is the network interface card (NIC). If a network card is not fast enough to handle the number of requests from other nodes on the network or from internal counterparts, all aspects of the network subsystem are affected. Tests are made to determine if a network card is too slow, or if there is too much data trying to be sent through the network.
To identify the network component being overused, tests are performed on the percentage of the network segment being used, the server service, and the workstation service (redirector). This reveals if the system is part of a busier network, is servicing too many requests, or is requesting too much.
The system administrator must determine whether to upgrade the server or workstation service, or whether to distribute the workload differently.
The server and workstation services are vital to the network operations of Windows NT and Windows 2000. Performance statistics for each service, such as bytes per second in and out, sessions with errors, or high requests to the services are examined.
