Prototyping of an interconnection border gateway function (IBGF) in next generation networks (NGN) using open source software tools

Abstract

This paper illustrates both the detailed theoretical setup of the Interconnection Border Gateway Function (IBGF) and its technical implementation using Open Source Software components. Moreover, a model is proposed to handle different traffic classes according to their corresponding Quality of Service (QoS) requirements while also forwarding "best effort" data traffic. The functionality is verified by evaluating data streams with varying QoS parameters, which are identified by an adequate packet marking method. © Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2011.
