How do you have to define by Network Architecture?
How do you have to define the Network Architecture? In 1977,the International Organization for Standardization (ISO) recognized the urgent need for standards for computer networks.It formed a committee that developed a standard model of architecture for networking system. Layered approach to Network Architecture:- The OSI reference model recommend a layered approach for network architecture.It consists of seven layers.Layering dividing the entire problem into small pieces. Some of the principal behind using layered approach are as follows:- ✍️ Each layer performs various well defined functions. ✍️Each layer provides services to the higher layer. ✍️The service provided by a layer is independent of how it performs the service. ✍️The number of layers should neither be too many nor too less.Collect similar functions into the same layer. ✍️At the same time a layer should be created where a different level of abstraction is needed.This would ensure separate f...
