Software defined network paradigm coupled with a visualization of network functions and services in developing new network and service infrastructures

摘要

The Software Defined Network paradigm, coupled with a visualization of network functions and services, will create the opportunity of developing new network and service infrastructures. In this respect one may imagine a sort of universal node, integrating processing, storage and networking capabilities, which is able to both process and route traffic. The work provide a didactical simple model of such type of nodes by using the fluid model. The results shows the possible dynamics of the traffic in a buffer of a router integrating also processing capabilities (internal or external blades): depending on the traffic profile, and the processing requests, the evolution of the amount of data in the buffer might have a great variance.
