Question

Difference between static and dynamic channel allocation in computer networks

Answer 1

Fixed channel allocation or static channel allocation does not allow reallocation of a channel throughout the operation after it has been assigned to a user or a port. One of the best examples of this type of allocation is digital cellular mobile networks.

Dynamic channel allocation does not restrict a channel to any specific user or node. All channels are kept in a centralized spool and are assigned to new calls whenever they arrive. After a call is completed, the channel is once again sent back to the centralized pool. This type of allocation is typically found in GSM networks.
