Tactical Edge Networks provide one of the most challenging communication environments. In order to cope with node mobility, constrained resources, and link unreliability, communication solutions designed for Tactical Edge Networks typically present highly configurable interfaces to be adaptable for various networking conditions. However, the extreme dynamicity and heterogeneity of tactical scenarios...
The current progress of network technique and the complication of network structure make administrators must spend more time and mind to maintain the system and the network under normal operation. With continuously increasing dependence on the network, it seems to be a knotty matter to know how to effectively manage all equipments on the network and to make sure they whether run it rightly or not...
Next Generation Networks (NGNs) transport a variety of services across a converged IP-based network infrastructure. To assure the Quality of Experience (QoE) for the users, an end-to-end Quality of Service (QoS) management is required. While solutions for QoS management and admission control in access and core networks exist, the inclusion of the home network remains still open. Thus, we present a...
A modern home could contain a large variety of devices and all of them should be able to work together so as to bring a rich experience to the users. Quality of service (QoS) is a critical factor for measuring user satisfaction. It represents the ability to provide different priorities based on the type of the data flows or to guarantee a certain quality of performance to a particular service. Different...
The present day Internet has no separate namespace for host IDs. It uses IP addresses as host IDs, which are in fact locators. This dual role is problematic for mobility, multihoming, security, and routing on the Internet. To solve these problems, research has recently begun on ID/locator split architectures. Some standardization activities based on this concept are also progressing in ITU-T Study...
The Home NodeB has been the hotspot in the mobile communication field. Comparing with Macro NodeB, Home NodeB has several features which bring the challenges for management. The paper proposes two alternative management architectures for the Home NodeB access network based on the different management requirements, and discusses the management elements in detail. These two kinds of architectures can...
In order to solve the problems that the process of the evolution is only in one step and the investment in network is so costly when the network in nowadays evolutes to NGN(Next Generation Networking), this paper has get a deep research about the soft switch, media gateway control protocol, access gateway and media server and such kind of technology and then submit a kind of design methodology, through...
The extended use of DMX512 protocol has been applied in many areas such as stage and theatre. While it has two inherent flaws in landscape lighting control: the quantitative limitation of control slots and slow bandwidth utilization ratio. This paper proposed the evolution of a management and control system for landscape lighting. By using the upper Internet management network, several lower DMX512...
We propose a 6LoWPAN-SNMP that enables transmission of SNMP messages over IPv6-enabled low-power wireless personal area networks (6LoWPAN). The 6LoWPAN-SNMP is an extended modification of the Simple Network Management Protocol (SNMP). Compared to traditional IP-networks, 6LoWPAN is a severely resource-constrained network; hence, existing SNMP protocols need to be modified to meet the goals in RFC...
Consistent and flexible policy and charging control is one key factor for effective access control and efficient resource management in IP-based multimedia communication networks. One approach to deal with this challenge is to put more decision logic into the so-called mediation layer which is residing between the operatorspsila core network and the charging system. This article describes our research...
Inter-enterprise collaborative environments and applications enable users to utilize and manage voice, data and video services on a common IP-based network. As voice moves from its traditional separate network to having both user and trunk connections traverse the corporate IP network, the demands for uptime and quality of experience increase dramatically. When video-over-IP is layered onto the same...
Worms not only infect vulnerable hosts, but also occupy a large amount of network bandwidth, which affects the normal operation of the network seriously. To achieve the worm detection and automatic quarantine in real time, a cooperation system of worm detection and quarantine is designed and implemented. The worm detection subsystem is implemented based on Bro and can detect worms in real time with...
Based on the comparison of congestion control between aeronautical telecommunication network (ATN) and IP network, a new congestion avoidance model considering the explicit congestion notification (ECN) in ATN over IP scheme, called explicit congestion notification in tunnel (ECNT) model, is proposed in this paper. In addition, a new ECN/CE mapping algorithm to map ECN signal in IP sub-network onto...
