“…A path selection with the end-to-end delay constraint is subject to inaccurate information due to the dynamic nature of the delay and hence subject to theoretical intractability ( [4] [5]). However, end-to-end delay and delay jitter bounds have been computed by means of network calculus applied to queueing systems modelling the ISSN: 2088-8708 networks ( [6,7,8]). Academic and industrial communities have been very active in the last decades in investigating network models and algorithms to solve the QoS routing problem, also known as the multi-constrained path computation problem ( [9,10,11,12,13,14,15]).…”

This paper describes a framework application for the control plane of a network infrastructure; the objective is to feature end-user applications with the capability of requesting at any time a customised end-to-end Quality-of-Service profile in the context of dynamic Service-Level-Agreements. Our solution targets current and future real-time applications that require tight QoS parameters, such as a guaranteed end-to-end delay bound. These applications include, but are not limited to, health-care, mobility, education, manufacturing, smart grids, gaming and much more. We discuss the issues related to the previous Integrated Service and the reason why the RSVP protocol for guaranteed QoS did not take off. Then we present a new signaling and resource reservation framework based on the cutting-edge network controller ONOS. Moreover, the presented system foresees the need of considering the edges of the network, where terminal applications are connected to, to be piloted by distinct logically centralised controllers. We discuss a possible inter-domain communication mechanism to achieve the end-to-end QoS guarantee.Copyright c 201x Institute of Advanced Engineering and Science.All rights reserved.Corresponding Author: Name: Francesco Lucrezia Affiliation: Polytechnic of Turin, Italy Address.

Digital contents are consumed by smart phones and sophisticated terminal stations that continuously evolve together with the applications they host. Interestingly enough, the evolution of the OverThe-Top (OTT) services is mainly happening without the aid of network service providers, within the best-effort data traffic channel in the access networks. Recently, a new plethora of applications requiring a RTT delay of around 1ms have been grouped under the hat of tactile-internet applications: a tactile sensor reads information and a connected system reacts with actuators seen by a human within 1 ms [1]. Although we are still far from achieving end-to-end RTT of around 1ms with wireless communications, ISPs need to be ready to re-architect their software control-plane in order to fully exploit the enormous potentials offered by their infrastructures. The goal of this paper is to present the design and a prototype implementation of a control-plane network application for provisioning dynamic end-to-end QoS profiles to end-user applications. The current adoption of distributed control algorithms forces the use of the same signaling protocol (e.g. RSVP, BGP-LS) in all the data-path nodes, not taking into account the resistances inevitably present between device vendors and between administrative domains. For this reason the Service-Level-Agreements (SLAs) between a service provider and its customers or between providers are still mainly static. Moreover, the experience has shown that the scal...

“…One way is to introduce a delay jitter regulator or rate regulator at each hop. The regulator delays a packet in order to keep constant delay jitter over the end-to-end path [6,7,8]. This method minimizes delay jitter increasing the mean delay and possibly reducing the throughput.…”

SWIM: A Scheduler for Unsolicited Grant Service (UGS) in IEEE 802.16e Mobile WiMAX Networks

Abstract. Most of the IEEE 802.16e Mobile WiMAX scheduling proposals for real-time traffic using Unsolicited Grant Service (UGS) focus on the throughput and guaranteed latency. The delay jitter and the effect of burst overhead have not yet been investigated. This paper introduces a new technique called Swapping Min-Max (SWIM) for UGS scheduling that not only meets the delay constraint with optimal throughput, but also minimizes the delay jitter and burst overhead.

“…This is because of the efficient use of bandwidth requiring fewer long-distance trunks between switches [2].Packet switched networks like Internet, are based on the Best-effort policy which does not guarantee a minimum packet loss rate and a minimum delay of packet transmission required for VoIP system. Ferrari et.al [3,4] had published work related to the effect of jitter and delay on real-time communication applications. Bolot et.al [5][6][7] also analyzed the performance of audio packets on internet for the various network characteristics.…”

In Voice over Internet Protocol (VoIP) system, the speech signal is degraded when passed through the network layers, since the best effort policy based IP network leads to the network degradations including delay, packet loss jitter. The transmission of voice over internet protocols requires signal processing for reliable & efficient performance over the communication platform. The work in this paper presents the effect network degradation factors on VoIP system and the spectral analysis of the VoIP signal. The lab experiment is performed to realize the VoIP system and to obtain the degraded database. The spectral analysis of VoIP signal is performed through the various signal processing algorithms. The results are validated through the quality evaluation of the VoIP signal using perceptual evaluation of speech quality (PESQ) measurement for narrowband signal.
