What are single stage and multistage networks? Compare the strengths and weaknesses of each.
OR
List the major difference in single stage, two stages and three stage Networks. Also discuss their blocking characteristics.
Single Stage Vs. Multistage Network.

|
1.
|
Inlet to outlet connection is by a single cross point.
|
Inlet to Outlet connection is by
multiple cross points
|
|
2.
|
Utilization of single cross point per connection
results in better quality link.
|
Utilization of multiple cross points may
degrade the quality of a connection.
|
|
3.
|
All individual cross point can be utilized for only single inlet/outlet pair connection.
|
Similar cross point can be used establish connection in between a number of inlet/outlet pairs.
|
|
4.
|
An exact cross point is required for each exact connection.
|
An exact connection may be established through using sets of cross points.
|
|
5.
|
If a cross points fails, connected connection cannot be establish. Means there is no redundancy.
|
Alternative paths and cross-points are available.
|
|
6.
|
Cross points are incompetently used. Only one cross point in every row or column of a triangular or square switch matrix is even in utilize, even if every line is active.
|
Cross points are used
Efficiently
|
|
7.
|
Number of cross points is
Prohibitive
|
Number of cross points
is reduced considerably
|
|
8.
|
A huge number of cross points in every inlet/outlet leads to capacitive loading.
|
There is no problem of capacitive loading
|
|
