Automatic Creation of Dynamic Circuits in Hybrid Networks Employing Traffic Filtering Rules

摘要

Dynamic circuits can reduce queuing delays and provide alternative routes to network congestions. In general, dynamic circuits are available to users who need to transmit large volumes of data and the circuits are explicitly generated by the users or by custom application systems. In this paper, we present a proposal for automatic generation of dynamic circuits based on rules, similar to a conventional packet filter. We have implemented and evaluated our proposal in laboratory and in the RNP. The results confirm the performance gains achieved by using circuits, which are over 100% in some scenarios. In addition, the results illustrate the effectiveness of our solution to migrate traffic on-going from the conventional network to the circuit. We also present a qualitative evaluation of our solution related to deployment and adoption of a dynamic circuit service.
