Time-Sensitive Networking (TSN) standards aim to support hard real-time communication with minimum latency based on Ethernet technology. They can also support the automotive domain considering upcoming and challenging application requirements in intelligent vehicles of the future. Despite all advantages, Time-Aware Shaper (TAS), a significant feature of TSN, increases the network configuration overhead...
Wireless Sensor Network (WSN) is one of the emerging technological fields due to recent advancements and area of research. The WSN is collection small sensor nodes, which are battery driven and have very less power. Recent research area of WSN focuses on energy consumption, routing, QoS, bandwidth, packet loss etc. This paper focuses on comparative analysis among various existing routing protocols...
A new scheduling module, the Selective Early Detection (SED) mechanism is proposed in this paper. An experimental evaluation in order to demonstrate how this algorithm succeeds in enhancing the quality, improving the performance and easing the deployment of a production level service is carried out. SED algorithm is useful in controlling the Actual average queue size, and hence the queuing delay,...
This paper proposes a new traffic control method to use both pacing and class base queuing (CBQ) methods in the next generation home network. Experimental setup and results are also described to verify the effectiveness of the proposed method. With the pacing and CBQ method applying to the simulated video streaming service in the hardware experiment, its quality of service (QoS) could be improved...
This article presents an approach towards aggregating bandwidths of multiple physical layers i.e. transmitting and receiving data simultaneously through the multiple physical interfaces of a fixed computing system. The data over physical layers can communicate over both wired and wireless communication medium at the same time. This proposed bandwidth-aggregation-system (BWA) enhances the download...
Recently, more and more services need high quality bandwidth. In order to satisfy those services, high-speed networks are needed. The Task Force team of IEEE 802.3ah set a standard as Ethernet Passive Optical Network (EPON) that is a next generation subscriber access network. IEEE 802.3av developed 10G EPON which has 10 times more capacity than EPON to solve the high quality problem. Research on 10G...
In this paper, we propose a bandwidth allocation scheme working with differentiated services for the Multi-Point Control Protocol (MPCP) in Long-Reach Passive Optical Networks. The proposed scheme is an enhancement to our recently proposed bandwidth allocation scheme Periodic Gate Optimization (PGO), and it is called Periodic Gate Optimization with Quality of Service Awareness (PGO-QoS). Long-Reach...
The mechanical control interfaces in automobiles are replaced rapidly by electrical interfaces in which the electric control units (ECUs) are connected through networks. Recently as the requirements on the infotainment applications for automobiles are increasing drastically, new automobile network called MOST (media oriented system transport) has been introduced. Due to its high bandwidth and QoS...
Active Queue Management (AQM) algorithm is important to manage buffers and transfer packets for wired/wireless networks. However, the unresponsive flows to the network congestion control is dangerous to the network equilibrium and Quality of Service (QoS), especially from the point of network resource allocation. In some certain scenarios, the limited network resource (buffers) can be occupied by...
In the increasingly popular Voice over IP (VoIP) application domain, a well known issue relates to the management of available network bandwidth which is usually constrained by uplink capacities as well as access point limitations in the case of wireless connections. An approach that has long been advocated for controlling the admission of new connections based on bandwidth availability is Call Admission...
Routers configure their paths based on the Link State Database (LSDB) in order to meet service requirements and Quality of Service (QoS) guarantee. Internet routing can be categorized into intra domain routing and inter domain routing, and QoS should be guaranteed both at the intra and inter domains for end-to-end QoS guarantee. The LSDB can be easily managed and updated at the inter domain routing...
IEEE P1900.4 is an emerging standard for optimized radio resource utilization where cognitive radio technologies are used for efficient spectrum utilization. In this paper, we design and implement a cognitive wireless network system based on open documents of IEEE P1900.4, and evaluate its performance using UDP streaming and HTTP download. Our experiments show interesting results that total network...
This paper describes a methodology for building a reliable internet core router that considers the vulnerability of its electronic components to single event upset (SEU). It begins with a set of meaningful system level metrics that can be related to product reliability requirements. A specification is then defined that can be effectively used during the system architecture, silicon and software design...
Distributed system design has propelled network communication service beyond best effort data delivery. Thus building the on-demand and QoS-aware communication paths between distributed software components emerges as a key research challenge. In this paper we present two QoS-assured source multicast services based on a simple autonomic service provisioning framework. These two algorithms can provide...
One of the vital key elements for providing quality of service (QoS) for VoIP is the call admission control (CAC) capabilities of the session management/call session control function or gateway. Even though the network may be designed to meet a given performance and restoration objective for the engineered traffic loads, the actual traffic may be significantly higher. Without a CAC function in a VoIP...
