Question

Discuss various design goals for the layered network architecture.​

Answer 1

Answer:

The main aim of the layered architecture is to divide the design into small pieces. Each lower layer adds its services to the higher layer to provide a full set of services to manage communications and run the applications. It provides modularity and clear interfaces, i.e., provides interaction between subsystems.

Answer 2

Answer:

Resource Allocation. Computer networks provide services in the form of network resources to the end users. The main design issue is to allocate and deallocate resources to processes. The allocation/deallocation should occur so that minimal interference among the hosts occurs and there is optimal usage of the resources.
