Performance Improvement of Multicommodity Flow of Tactile and Best Effort Packet in Internet Network

Student thesis: Doctoral ThesisDoctor of Philosophy

Abstract

Tactile Internet is an advanced technology which enable transfer of content and skill of human resources through haptic communication. The implementation of tactile internet will not use a private infrastructure because it would not be economical. The tactile internet will be realized by sharing the network resource with the best-effort internet packet.

This study investigated the methods for multi-commodities flows, comprise of haptic and best-effort packet, which will improve the network utilization and throughput. It also minimize the network cost such as: total delay and packet error.

Moreover, through this study, it has been ensured that the QoS requirement for haptic packet could be achieved. Some methods investigated for this work including routing and scheduling of the packet in the network. The analysis of minimum routing cost for Tactile and Best Effort Packet conducted by implementing Traffic Engineering in the network.

Furthermore, Software Defined Network (SDN) paradigm introduced and implemented to control every single edge nodes in the network, so the optimal traffic engineering for tactile packet and best effort packet could be realised. From the results can be seen that our solution enhances system throughput and mitigates congestion among flows in comparison to single-path shortest routing.

In the end, we also proposed the methods to deal with many types of traffic, including tactile and best effort traffic, by formulating multi-criterion optimisation problem. By tuning the allocation of bandwidth capacity of tactile and best effort traffic, we able to use the optimisation approach to get an optimal revenue of the communication network.
