The current Internet has been hugely successful in achieving global connectivity between a large number of diverse networks, devices and users. This success is due to the openness of the architecture and the general philosophy of allowing any system to communicate with any other system on the network. Such open standard has made it possible for everyone to communicate, offer service and make profit thereby creating an indispensable impact on everyone's lives so Internet suffers from the problem with the tightly coupled layered architecture. So there should be loosely coupled architecture of internet.
