In this paper, the SMART grid concepts and technology that can be potentially applied to address key challenges in future Naval vessels are analyzed. The IEEE standards for designing various modules for naval vessels such as Integrated Power System (IPS) are discussed and proposed potential architecture for power management module in naval vessel IPS to supply SMART grid concepts.
This study proposes a novel method of evaluating hierarchical relationship between QoS and QoE for Web services by utilizing the path analysis and the principal component analysis. The proposed method shorten the number of QoS parameters each layer with the principal component analysis; it then clarify the relationship between the QoS and the QoE by performing the path analysis. To confirm the effectiveness...
The IP Multimedia Subsystem (IMS) is a standard network technology merging voice, data, and multimedia services. IMS is well integrated with existing voice and data in wire and wireless networks. To ease the integration with the Telecom and Internet networks, IMS use SIP (Session Initiation Protocol). The main components of IMS are CSCF's and HSS servers. They are responsible of processing and routing...
In this paper, the authors develop a novel wireless LAN base station with DPI(Deep Packet Inspection) based QoS control, which can maintain QoE during congestion. In the QoS control, the base station always monitors the file type which is found in HTTP messages encapsulated in an IP packet and prioritizes the packet. Since the control is light weight, it can be easily implemented a LAN base station...
Energy saving and quality of service are the most popular but contradictory criteria for resource allocation in IP-over-WMD network. Establishing of direct lightpath according to bypass architecture of IP-over-WMD network becomes reasonable when arriving traffic exceeds some threshold while under the threshold traffic have to be routed via compound path if it exists. On the other hand compound path...
In this paper a method of evaluating connection quality of IP-networks is considered. The mathematical model of the functioning of the network was made and the estimation of the quality parameters of its work for various values of subscriber traffic. In particular, the algorithm of calculating the delay time of the packet transmission network was made when using the quality assurance mechanisms IntServ...
Controlling the jitter buffer at the receiver side is a key component in multimedia and real-time services. A jitter buffer is used to control the packet rate and to compensate for the delay variation, commonly called jitter, by the tradeoff between delay and loss. In this paper, we present simulation results for the relation between the over- and underflow probabilities and the jitter. We then show...
QoS guarantees for real-time HD video transmission can be assured by proper resource allocation. The TFD option of the IP protocol can be used to convey signaling information about required resources for a given transmission. In this paper the new traffic description for TFD option, based on analysis of scene changes, is presented. The traffic description was carried out in two stages. First, scene...
This paper provides an IPv6 mobility and multi-link solution proposed in SESAR project P15.02.04. It is based on the Locator/Identifier Separation Protocol with the goal to minimize the complexity in the aircraft and the overhead in the A/G datalinks. This solution is a ground based network solution, where all the routing and mobility functionalities are necessary only in network equipment on ground,...
The Traffic Flow Description (TFD) is a new option of the IP protocol, designed by the Authors for Quality of Service (QoS) signaling. In contrast to the traditional, long-term, RSVP-based signaling, which is able to serve only static QoS assurance, the TFD option provides signaling on different time horizons, enabling dynamic QoS assurance. The TFD option conveys information about forthcoming traffic...
The video, voice, multimedia next-generation applications are using real-time data transmissions. Therefore, taking into account that all these applications are transmitted “over IP”, variable bandwidth has to be provided for specific situations in order to prevent network congestion. The active equipments meet these requirements and provide the network management. However, how will it be if the network...
This paper describes an architecture for global queue management (GQM). Global refers to the set of all queues in routers present in some network flow path. The main idea of the architecture is the detection of some anomaly somewhere downstream and the propagation of the local decision to a set of upstream routers or switches. The upstream devices are free to act as they wish. GQM is useful to boost...
A method to automatically configure the limitation mechanism in Flow-Aware Networks is presented in this paper. First, the concept of Flow-Aware Networking with special focus on the limitation mechanism is outlined. The automatic limitation mechanism i.e., a mechanism which automatically selects the most suitable flow admission limit during a measurement cycle is proposed, presented and analyzed....
In order to solve the problem of on-board optical burst switching assembly algorithm cannot realize completely QoS guarantee, an on-board optical burst switching weight-weighted round robin assembly algorithm based on the QoS guarantee(QWRRA) is proposed in this paper. In this assembly algorithm, IP packet will be inserted in different queue according to the different destination and QoS level when...
There are hundreds of billions packets passing through the network, how to analyse these big data is an arduous task. In this paper we proposed a new scheme based on cluster algorithm to explore the backbone network traffic pattern. Two new traffic features are introduced to assist the analysing process. These two novel attributes can represent the flow effectively cooperated with a new flow similarity...
This paper proposes a technique to split a traffic in a software-defined network using a meter table. In general case, a different differentiated services code point (DSCP) number in a packet header is used to classify network traffic and provide quality of service (QoS). The traffic splitting technique uses a DSCP number as a split parameter. Once a packet exceeds a predefined traffic rate, the DSCP...
The paper is about the problem of reducing the power consumption in Video Distribution Networks (VDNs) under the condition of best performance provision in terms of Quality of Experience (QoE) measured at the end user. Related to this, it has been observed that, given an end-to-end video distribution network, it is the last networking segment ending to terminal that has the dominant role in the provision...
The management model for the process of IT-services guaranteed level assurance is considered. Quality level of service is controlled by applying the alternative technologies for information flows processing and IT-services structural reconfiguration in the Enterprise Resource Planning system (ERP-system). The example, that illustrates the decision-making process with the use of game-theoretic approach,...
This paper proposes a highly simplistic 5G core network design. Instead of providing mobility support and Quality-of-Service for all traffic as in the 4G core network EPC, the default service of 5G should be connectionless, best effort and without support for node mobility. This is based on the observation that applications like video streaming or web surfing that create the bulk of the traffic in...
