Cloud monitoring involves dynamically tracking the Quality of Service (QoS) parameters related to virtualized services (e.g., CPU, storage, network, appliances, etc.), the physical resources they share, and the applications running on them or data hosted on them. Monitoring techniques and services can help a cloud provider or application developer in regards to: (i) keeping the cloud services and...
The Hard Real-Time Ethernet Switch (HaRTES) allows using the same network to handle multiple traffic flows, without compromising the performance of real-time applications. Furthermore, it also provides flexible and on-line scheduling techniques with admission control capabilities, thus real-time communications flows can be added, removed and updated online with strict temporal isolation. However,...
In the context of modern high-speed internet network,monitoring model is often complicated by the notion of guaranteed Quality of Service (QoS). we first analysis the conventional network quality of service,then we proposed a monitoring model for securities trading network quality of service,the main functions include network quality of service monitor, fault alarm,analyse and so on which can better...
This paper describes how information collected by enterprise system management (ESM) platforms can be utilized in a novel approach to assess the information assurance delivered by an information system. We describe the assessment approach first and then explain the interaction patterns between the ESM platform and the assessment mechanism in the context of our prototype implementation.
Energy saving has become a global issue when people use network enabled equipment in the office or at home. However few methods exist to measure and monitor energy use per user or per application, or to control equipment power states. We propose a generic energy consumption model that is based on the power state of network attached equipment, and that supports power management capabilities. This includes...
WiMAX features several QoS service classes to schedule different types of traffic. In this paper, we will assess the existence of self-similar traffic for each service class. The experiment starts by capturing the traffic data with a dedicated SNMP-based network management system (NMS). NMS manages the deployment of fixed WiMAX network defined in IEEE 802.16d-2004 Standard and records the inbound...
As a system for guaranteeing Quality of Service of continuous media by traffic control, there exists Integrated Services using Resource ReSerVation Protocol that guarantees bandwidth for object traffics by executing bandwidth control. This system, however, restricts bandwidth for other traffics through the session of object traffics because of its static bandwidth control. Then, to solve the problem,...
The MobileTV, IPTV, and DVB standards (DVB-H/T) have been defined to offer mobile users interactive multimedia services with quality of service (QoS) consistency analogous to TV services. However, the market has yet to provide effective and economical solutions for the real-time delivery of such services to the corresponding transmitters over multi-domain IP networks. The monitoring system proposed...
In the theater of war, mission-critical information is delivered over tactical networks, and a brigade dynamically conducts close combats and tactical operations on the basis of the military information. Therefore, the quality of service (QoS) of military information should be guaranteed to successfully perform tactical operations in the battle field. In this paper, the concern is a QoS framework...
In this paper we present a prototype implementation of a management scheme that can be used to dynamically manage Guaranteed Performance Connection (GPC) services in Integrated Services Networks. These services are required to support the wide range of quality-of-service parameters desired by many useful applications. The GPC services provide performance guarantees in terms of throughput, delay,...
