traffic analysis
|
how much traffic must flow over the network's many individual transmission lines
|
|
|
two-site traffic analysis
|
You must be able to compute what traffic a line must carry in each direction to select an appropriate transmission line; transmission line must support highest.
|
|
|
three-site traffic analysis
|
must use sum of requirements from site A to site B and site B to site C
|
|
|
redundancy
|
requires extra throughput; not necessary, but provide backup paths in case another line fails
|
|
|
topologies
|
physical layer concept; describe the physical arrangement of nodes and links.
|
|
|
types of topologies
|
- Point-to-Point
- Simple Star (Ethernet) - Mesh (Router) - Extended Star (Ethernet) - Bus - Complex |
|
|
point-to-point
|
simplest topology; 2 nodes connected directly
|
|
|
simple star (Ethernet)
|
all wires connect to a single switch; limited to number of ports
|
|
|
extended star (Ethernet)
|
multiple layers of switches assembles in a hierarchy; each node has one parent; core switch and work group switch
|
|
|
mesh (Router)
|
many connections among switches or routers, so there are many alternative paths to get from one end of the network to the other; TCP/IP standards designed for this topology
