A New Packet Scheduling Algorithm for Real-Time Multimedia Streaming

Abstract

Delivering the real-time services over converged networks is a big challenge. Real-time services need to high Quality of Service (QoS). For this purpose, bandwidth reservation and packet prioritization techniques are used. Thus, real-time data packets can be reached to their targets with minimum delays and losses.But, this situation creates unintended consequences for other internet services such as HTTP and FTP. In this case, establishing a balance between the real-time services and the other services is a must. In this study we introduce a new research question: how to transport real-time multimedia IP packets just in Network Protocols and Algorithms ISSN 1943-3581 2017 www.macrothink.org/npa 29 time? Just in time means that transportation of the packets neither early, nor late. For this purpose we developed a scheduling/prioritizing algorithm called just in time transport (JITT). Following a cross-layer design approach, JITT controls delay and jitter over whole communication path. We evaluated JITT on the different simulations and one experimental testbed for performance analysis. Our findings support that JITT provides stable delay and low jitter and transports the packets nearly just in time.

“…The comparison with the other related works shows that our proposal is the only one that introduces AI and SDN to modify OSPF protocol. With these modifications, we achieve real time improvements and adaptive routing, which is currently needed to provide real-time services (see [168] and [169]).…”
