Available Bandwidth Estimation in Smart VPN Bonding Technique based on a NARX Neural Network

Abstract

Abstract-Today many applications require a high Quality of Service (QoS) to the network, especially for real time applications like VoIP services, video/audio conferences, video surveillance, high definition video transmission, etc. Besides, there are many application scenarios for which it is essential to guarantee high QoS in high speed mobility context using an Internet Mobile access. However, internet mobile networks are not designed to support the real-time data traffic due to many factors such as resource sharing, traffic congestion, radio link, coverage, etc., which affect the Quality of Experience (QoE). In order to improve the QoS in mobility scenarios, the authors propose a new technique named "Smart VPN Bonding" which is based on aggregation of two or more internet mobile accesses and is able to provide a higher end-to-end available bandwidth due to an adaptive load balancing algorithm. In this paper, in order to dynamically establish the correct load balancing weights of the smart VPN bonder, a neural network approach to predict the main Key Performance Indicators (KPIs) values in a determinate geographical point is proposed.

“…Some of these applications require higher bandwidth requirement than others such as Quality of Service (QoS) based transmissions and video communications. Hence, to resolve the imminent issue of bandwidth requirement, authors in [15] proposed smart VPN bonding scheme. In this scheme, more channels are bonded together to fulfill the requirements of end user.…”
