Improving Network Connectivity by Deploying WAN Bonding Concept

Abstract

This Master’s Thesis introduces how Wide Area Network links can be combined. As a result, more reliable connectivity in terms of bandwidth, availability, latency, network security and reach can be achieved. This topic is currently actual since business applications of today often rely on high uptime driven by cloud computing, voice and video communications etc. Moreover, an Internet of Things (IoT) ecosystem is largely based on high availability and high-secure connections. However, 100% uptime is today quite far from the reality. Users may suffer from unreliable Internet links and due to this they do not get the coverage, availability and capacity they need in order to smoothly run their business. The main reason for this is that they normally rely on one technology or one service provider only.

The thesis first demonstrates WAN technologies in common as well as WAN optimisation techniques. The effectivity of the WAN bonding is evaluated in comparison to e.g. load balancing. The main objective of the thesis is to adduce the benefits of WAN bonding as a solution in enhancing network connectivity. Here, the risks can be decreased by bundling several different media into one virtual high-speed Internet connection.

The outcome of this Thesis is a description of new potential use cases for WAN bonding technology in several industries and contexts. In addition, new kinds of business models for network operators and ISPs are outlined. The given examples may help operators and ISPs to develop new innovative business. On the other hand, by deploying the solution, users will experience an easier way to achieve an increase in bandwidth, availability and reach without having to re-negotiate with their current ISP.
