Adopting and Performance Evaluation of WebRTC-based cloud CPaaS: In the case of Ethiotelecom

Abstract

Cloud computing has become a leading technology solution for most of current problems in various sectors in terms of cost and security. Either in private enterprises or public domain cloud computing offers a vast amount of resource in computing, storage and network bandwidth. Presently most of service providers or telecoms such as broadband internet service providers suffer a lot from customer complaints using various cloud technology such as real time communication that are hosted outside the provider autonomous system. Due to various type of OTT (Over the Top) service over internet and other telecom frauds has a huge challenge in revenue, captical expenditure and operational expenditure. In this thesis research proposal, Adoption and Performance evaluation of web real-time communication (WebRTC) technology that’s integrable with other serivices is presented as Communication platform as a service (CPaaS) in the case of Ethiotelecom. The proposed design evaluated in general QoS bandwidth and Routing complexities in enterprise network including a symmetrical NAT setup that will provide shortest path between peer-to-peer communications. CPaaS cloud provisioning algorithm presented using Cloudsim plus simulator for various types of virtual datacenters and resource. The paper tries to depict that cloud communication platform as a service can be beneficial for internet service provider like Ethiotelecom without compromising their core service performances. The test results have displayed reduced NAT (Network Address Translation), low bandwidth consumption on the provider network, reduced congestion on internet gateways with the implementation of WebRTC inside ISP. Finally, WebRTC implementation from grean computing perspective, allows ISP use their resource efficiently by incorporating informaction technology by still maintaining the overall service performance.
