Facets of a digital infrastructure

We have discussed how networks should behave, and the services that a network should deliver for a new age IT infrastructure. This section talks about network design requirements and the various characteristics that should be considered while designing and implementing a network. Most of these have been the basic guiding principles even before the digitization wave, which shows that these principles have stood the test of time. A network that has to meet the requirements of a dynamic organization, however, has new principles that need to be considered such as agility and programmability. This section focuses on the different parameters that can be used to measure the effectiveness of the network design.
