Paper Abstract:
|
In the last years there has been a huge increase in the number and variety of IP applications. An accurate mapping of
traffic to applications is important for a broad range of network management and measurement tasks including traffic
engineering, service differentiation, performance/failure monitoring, and security. Port-based identification approaches
have become increasingly inaccurate because many applications use non-default or ephemeral port numbers or use wellknown
port numbers associated with other applications. Thus, a more accurate identification demands the examination of
the user's payload. This paper presents a framework for processing IP traffic flows, enabling the calculation of a set of
relevant statistical parameters and the identification of the underlying IP applications by using payload analysis
techniques. The proposed framework is able to achieve good identification results and will be incorporated in a totally
distributed monitoring platform as a module that can be used at each probe for traffic engineering purposes. |
