Windows NT Networking
Networking Support
- NetBEUI - Allows over 254 sessions in version 3.0, but is not routable.
- IPX/SPX - Has network numbering scheme weakness. Does not support SNMP.
- TCP/IP - Required for WINS and is routable.
- AppleTalk - Not TDI compliant, but is routable.
- DLC
In TCP/IP, a DHCP server can configure the IP address, subnet mask, default gateway address, and DNS server address for the client computer. The network session layer supports NetBIOS, named pipes, RPC, netDDE, and most interprocess communications mechanisms.
Network Operating systems
- NetWare3.12 - Fast. Does not support logon to multiple servers at one time. Cannot execute non NetWare programs on the server. Uses cooperative multitasking.
- NetWare 4.x - Allows logon to multiple servers at one time. Provides directory services. Can run programs in separate memory.
- Banyon Vines - Runs on top of UNIX systems. Uses protocols to control client access to host UNIX systems. Provides directory services. Windows NT StreetTalk service component allows Banyon Vines networks to migrate to NT.
- UNIX
- Macintosh
Network Capability
Using more than 75% of the values may cause network problems.
| Network Type | Capacity |
|---|
| 10Mhz Ethernet | 100 |
| Token Ring | 200 |
| 100Mhz Ethernet | 500 |
| FDDI | 1000 |
| 1G Ethernet Fiber channel | 10000 |
| ATM-155 OC-3 | 1000 |
| ATM OC-12 (622M) | 4000 |
| ATM OC48 (2.2G) | 16000 |
| ATM OC192 (8.8G) | 48000 |
Servers may be centrally located on a fast backbone with each group connecting to the backbone, or the servers may be distributed on slower networks with each group and managed by each group.
Networks and Backbones
Some networks:
- ATM-25 - 25 Mbps
- ATM-155 - 155Mbps
Backbone:
- FDDI - 100Mbps
- ATM - Uses high speed circuit switching in star hierarchies. May have problems with large TCP/IP packets.
- Ethernet - 1G over fiber optic has high cost. Full duplex fast ethernet is lower cost, but has distance limitations.
