Student thesis: Master's Thesis


Video streaming applications have become a popular way to deliver media contents increasingly since Internet changes itself fast with the time not only hardware but software However it is difficult to address real-time streaming of multimedia over Internet because of the lack of overall network resources therefore it is hard to dealing with steaming to multi-users Software-Defined-Networking (SDN) is an emerging architecture which helps to handle this issue mentioned previously This research proposes a mechanism that helps to deal with this issue Our mechanism focuses on the user information including user buffer size or current bandwidth to improve Quality of Service (QoS) such as transmission latency The mechanism consists of two main elements including predicting module and scheduling module Predicting module can figure out the time stamp of latency occurred; scheduling module can create the schedule according the deadline of each segment to reduce latency At last this research uses Mininet to simulate this work The result shows that this methodology has a good performance and reduce latency well
