Wireless monitor system are widely used in recent years, but there are a few problems to solve, such as scalability and adaptability, and monitor system based on MANET has more difficulties because of multi-hop links and mutable channels. A new MANET monitor system based on Service-oriented architecture (MMS-SOA) is proposed to make the system easier to manage dynamically such as dynamic deployment,...
Mobile network has been tremendously increased in the number of users, diversity of applications and of interface technologies. Also mobile network need to provide sufficient adaptive End-to-End QoS management mechanism to provide enhanced user satisfaction. In this paper, we propose a new adaptive End-to-End QoS management mechanism based on the concept of utility function which we have borrowed...
The advent of IP communications challenged the use of legacy charging methods. Moreover, the diversity of Internet applications complicates the deployment of charging schemes in converged networks. Charging requires the collection of accounting information of resource usage, a process that consumes system resources that are needed for service delivery. Flat rate charging is popular on the Internet;...
Next Generation Network (NGN) management represents an enormous challenge due to the large number of managed elements, the variety of roles the managed entities play in the network and the difficulty of orchestrating management actions. Several NGN standardization bodies point toward policy based management as the best approach for NGN network management. This paper describes a management solution...
Multimedia flows transport over multiple IP domains requires quality of services (QoS) guarantees. In multi-domain contexts, the end-to-end QoS assurance needs cooperation of several resource management entities. Cooperation of the domains but also preservation of each domainpsilas autonomy are both required. This paper presents results on functional validation of a multiple domain overlay-developed...
The current network management makes the service provider shift from the backend to frontend in order to provide the user satisfactory service. It also leads to the researchers pay the more efforts on the study of integration of QoE and QoS, which provide a better analysis of the service management from the user perspective and from the network perspective respectively. In order to ensure the quality...
As streaming videos are becoming increasingly popular, it is important to understand the end-to-end streaming system and to develop effective algorithms for quality control. In this paper, we address the problem of rate control for streaming videos with a control-theoretic approach. Among the various control knobs, video bit rate is one of the most effective in the sense that it has a direct impact...
SON (service overlay network) is an effective mechanism to support end-to-end QoS guaranteed contents delivery service for IPTV service in NGN. The advantage of the SON architecture is to reduce the complexity of network control and management. So the SON can help to provide end-to-end QoS to users. To provide SON service, the provider has to purchase bandwidth and QoS guarantees from the corresponding...
In this paper, we study how to build a front-end flow management system for SIP application servers. This is challenging because of some special characteristics of SIP and SIP applications. 1) SIP flows are well organized into sessions. The session structure should be respected when managing SIP flows. 2) SIP has been adopted by telecom industry, whose applications have more critical QoS requirements...
The primary objective of 3GPP IMS was to define architectural components and interfaces of a session management core that is transparent to the underlying access technology and user device connected to it. To meet this objective, it has worked on defining an abstraction of the Access Plane by identifying the interaction requirements between IMS core and access plane and defining interfaces between...
