Risk exists throughout the entire life cycle of the project. It is an important guarantee for the success of the project to establish a good risk management mechanism and the risk-based decision-making mechanism. Personal communication tries to connect various telecommunication services to people, one of the key technologies to realise personal communication is to establish an advanced intelligent network—a kind of communication network that can provide and deal with the intelligent new businesses. It is an important guarantee for the success of the project to establish a good risk management mechanism and the risk-based decision-making mechanism.展开更多

In this paper, through the analysis of the ARP protocol works, it discusses ARP protocol AR P virus are two common attacks from the IP address to the security risks that exist in the physical address resolution process, and then analyzes in detail, and then introduces the AR P Find virus source and virus removal methods, and finally putting forward effective measures to guard against AR P virus.展开更多

It combines the two factors, contingency likelihood and severity, that determine system reliability, into risk indices on different loads and operation modes, which provide precise evaluation of the power grid＇s security performance. According to these indices, it can know the vulnerable area of the system and whether the normal operating mode or repair mode is over-limited or not, and provide decision-making support for dispatchers. Common cause outages and equipment-aging are considered in terms of the establishment of outage model. Multiple risk indices are defined in order to reflect the risk level of the power grid more comprehensively.展开更多
