Network Model
Network protocol
- Network must use a protocol in all case
- Protocol is a set of standards that govern network data transmission
- A popular one is TCP/IP (vd File Transfer Protocol FTP)
Network topology
- Is the way to config a network
- Physical topology vs Logical topology
Hierarchical network
- Mirror the actual operational flow in company
- Drawback: if add more processing level, network become complex and expensive to maintain
Bus network
- Device có thể gắn hoặc tháo khỏi network mà ko gây ảnh hưởng đến phần còn lại
- More user and device will affect overall performance
- Today not popular
Ring network
- Data flow in only 1 direction from one device to next
- Drawback: if a device fail, downstream devices cannot connect to network
Star network
- Drawback: entire network depend on the central network device (switch)
- However, back up switch is available immediately
Mesh network
- Each device connect to each other
- Extremely reliable but expensive
- Originally develop for military
-
