Summary:
|
There are some disadvantages related to payload-based application/service awareness technologies and some application scenarios that they can’t take effect.
It is necessary to find another class of application/service technologies to solve the problem related to payload-based application/service awareness technologies, and deep flow inspection(DFI ) is the proper technology. DFI is a class of service/application awareness technologies that uses an application recognition technique based on traffic behavior, where different types of applications exhibit different states on session connections or data flows.
DFI can be applied in the application scenarios in which payload-based application/service awareness technologies are not appropriate to be used. In reality, DFI can be used in all application scenarios that need service/application awareness functions.
It is helpful to specify requirements and capabilities of DFI because it can facilitate design, implementation, deployment and inter-working of DFI functions.
