Internet becomes a back bone of the communication network in the current era. People are very much dependent on the internet to connect from one end to another globally in todays environment. Internet suffers from the problem with the tightly coupled layered architecture. So there should be flexible architecture of internet. Flexible architec- ture will reduce the tight coupling of the layers. Selection of service and Composition of service is also an issue which will be solve through our framework. So we propose a framework of flexible network architecture which will provide flexibility to user for their application. This framework has many advantages like availability of services, load distribution, ser- vice discovery through the cloud technology. Cloud has a group of nodes which will act as single node to discover service and provide a service .It is a capable to create a mirror image of the broker node. Flexible net- work architecture is a combination of blocks. These blocks are functional module. Our framework will maintain also performance of the network. Keywords: Future Internet, Service oriented architecture, Flexible net- work,Cloud management,Service selection and composition. 1 Introduction Nowadays Internet is a well known term in the communication environment. Internet plays an important role as a medium to transfer the information from one end to another end of the world. In the current real communication, internet plays a role as a back bone and use to connect the entire world. Today in fast growing environment people are dependent on the internet to perform a various task such as information gathering, searching, resource sharing, software, audio, video data, selling and buying a goods like books etc. Internet provides a platform to develop a new thing such as software, instruments, architecture etc. which will be fruitful for the society. In 1985 internet was a collection of 50 sites and 1000 nodes approx [1] to con- nect the group of people and researchers but today internet spread itself with very fast growing speed due to its characteristic. Billions of user depends on the internet as a logical resource. So it is responsibility, today’s present researchers that all resources must be available, up-to-date, fault tolerance reliable. All these important factors can affect current architecture of the internet. Current internet K. Singh, A.K. Awasthi, and R.
