The purpose of call admission control in Controlled-load Service network is to offer a Quality of Service (QoS) commitment to guarantee that QoS bounds are not violated. The traditional way of achieving this goal by declaring the worse case traffic descriptors for the incoming calls results in poor bandwidth utilization. In recent years, measurement-based admission control has become an appeali...

Different quality-of-service (QoS) required types of multimedia services and need a guaranteed service rate in wireless multimedia networks. When the number of user arrivals increases, bandwidth degradations may occur due to limited bandwidth nature of cellular wireless networks. The bandwidth that should be assigned to user cannot be met for QoS provisioning in congested network. In this paper...

Datacenter is usually shared among different applications and tenants as cloud service infrastructure. Traditional network allocation reserves the bandwidth but the traffic behavior is unpredictable. InfiniBand (IB) is more widely applied in the construction of datacenter cluster and attracts more interest from the academic field as well. In this paper, we first propose an IB bandwidth allocati...

A bandwidth control mechanism is proposed for ATM networks that can control the usage of bandwidth in the presence of both connection oriented and connection less tra c as well as multiple classes of connectionless tra c The bandwidth control mechanism operates at three levels At the topmost level bandwidth is dy namically regulated between connection oriented and connectionless tra c based on ...

Cloud and IoT applications employ a wide range of advanced hardware and software techniques. This paper focuses on utilization of network bandwidth, and proposes the concept of "Bandwidth as a Service" (BaaS) between devices in cloud and IoT environments. Conventional controls for bandwidth are discussed, and a novel algorithm is proposed for dynamically shaping bandwidth into percentage groups...

Compressed video transmission over UDP/IP-based networks leads some challenging studies. One of them refers to the problem of minimizing the burstiness of video compressed traffic as it leads to poor network bandwidth utilization. Video smoothing has been proposed as one solution to this problem. This paper presents a smoothing algorithm to reduce such burstiness. The algorithm can bring good r...

This document describes a method to improve the bandwidth utilization of RTP streams over network paths that carry multiple Real-time Transport Protocol (RTP) streams in parallel between two endpoints, as in voice trunking. The method combines standard protocols that provide compression, multiplexing, and tunneling over a network path for the purpose of reducing the bandwidth used when multiple...

Abstract The cable industry is beginning to migrate to 100G core optical transport waves, which greatly improve fiber utilization while lowering transponder count for equivalent transport bandwidth. However, transporting 100G waves requires complex optical modulation to preserve performance and increase spectral efficiency. These modulation methods require several additional discrete optical co...
