Network Management
Possible network topologies:
-  Flat (all elements are at the same level-3) 
-  According to the physical layout of equipment 
-  According to functional requirements 

- An important element is the "intermediate distribution frame (IDF)
- Termination point for all floor's machines
- Label each frame with building, floor, and serial number
- Label each connection with room number and jack identifier 
- Example 1/4/2/12A: building 1, floor 4, frame 2, room 12, jack A

In large buildings a main distribution frame (MDF),
often located at the data centre,
acts as a central hub.
Basic principles:
-  Simple architecture 
-  Reliable implementation 
-  Labeling and documentation 
-  Use the best wiring you can afford 
-  UPS at the distribution frames 
-  Consistently locate IDFs on each floor
-  Use clear demarcation points for network providers 
-  Utilise open protocols (IETF, IEEE) 
-  Adopt simple routing 
-  Use specialised routers (not general-purpose computers) 
-  Minimise number of vendors 
-  Avoid bleeding-edge technology
