Mobile core traffic balancing by OpenFlow switching system
Ebrahim Ghazisaeedi, Rahim Tafazolli · 2013
Nowadays, one of the main problems of mobile operators is to handle network traffic more resourcefully. Techniques, which increase the traffic capacity over the mobile core with minimum costs, play a fundamental role. Following advent of smart phones, the most of the traffic bandwidth is being used for connecting to external IP networks, like the Internet. Consequently, this overloaded traffic causes congestion over the mobile core network and degrade the quality of service. In this regard, we suggest a process, by benefiting from recently revealed switching system (OpenFlow), in order to balance the traffic over the mobile core network and use resources more efficiently. In this paper, we imply a technique to decrease the core network load using this switching system and provide a better quality of service for specific services over 3G and Evolved Packet Core (EPC). Mobile Operators with the proposed solution may save millions of dollars per year.
