This paper discussed the, meaning and related techniques of constructing the high-performance WEB sites for the self-help service system, for the sake of advance usability and dependability of the self-help service system, design the project that carrying out gather-group technique of servers and load-balanced technique in system, it is mostly considered the complexion of the difference construct...
This paper describes a method of digital audio public address (PA) system based on Ethernet. The main framework of the system is proposed and the core techniques are analyzed. The hardware design of network audio devices and software design are described in details in this paper. CYCLONE II EP2C5FA484 programmable FPGA chip and audio codec VS1003 are proposed in the network audio terminal design,...
The Media Switch is an end-to-end total solution deployed in data center, broadband central offices, and customer premises. The Architecture is designed to fit the common WAN network hierarchy with high reliability and scalability. The systems that reside in the data center are Media Asset Management System, Media Acquisition Control System, Subscriber Management System, Billing System, Content Management...
A managed wireless mesh for infrastructure-level, stable regional mesh network has been studied. NerveNet, which we have been proposing, is a concept of future regional platform network that covers local regions and provides various context-aware services with the shared use of sensors and actuators. The managed wireless mesh developed for materializing NerveNet features auto-configuration of multiple,...
To dramatically improve the efficiency, resources and applications availability within the institution, now, the step that must be made it seems very small and achievable through virtualization. The reduction of the capital and operational costs it will be made by virtualizing the IT infrastructure in a “virtual” infrastructure, obtaining in the same time an increase of the efficiency, utilization...
This paper shows a new DNS attack that hijacks DNS requests by frequently injecting fake DNS server, and then network systems communicate with wrong destinations. This type of attack is detectable by neither the IDS nor any anti spoofing software.
In distributed file systems, a need may arise for relocation of the file system to a different server. This is one of the fundamental mechanisms for ensuring file service availability for the geographically distributed clients. However, migration or replication in many such systems requires that the client or client side daemons take active measures for accessing the alternate servers, thus compromising...
A new model of network security assessment is proposed in this paper. A single IT entity is evaluated through EAL; The composite IT entities are evaluated by CAP. The model analyzes the security value of network elements, and adopts the Geometric mean method to determine the security value of the entire network. The effectiveness of this method is validated through the evaluation of a practical system.
A service provisioning system is examined, where a number of servers are used to offer different types of services to paying customers. A customer is charged for the execution of a stream of jobs; the number of jobs in the stream and the rate of their submission is specified. On the other hand, the provider promises a certain quality of service (QoS), measured by the average waiting time of the jobs...
