										Abstract: Nagios is a stable, scalable and extensible enterprise-class network and system monitoring tool which allows administrators to monitor network and host resources such as HTTP, SMTP, POP3, disk usage and processor load. Originally Nagios was designed to run under Linux, but it can also be used on several UNIX o132perating systems. This chapter covers the installation and parts of the configuration of Nagios. The purpose of this paper is not only to introduce to everyone the concept of distributed monitoring with Nagios but capturing the beauty of it to improve the security of computer networks. Firstly, an introduction to Nagios will be discussed to provide readers a brief overview of what Nagios is. Next, it will discuss how distributed network monitoring is an essential part to information security. It will then proceed to introducing the requirements needed to build a distributed Nagios network monitoring environment and demonstrate how Nagios can be configured to construct a distributed monitoring environment that helps improve the state of security of distributed networks. In essence, companies  hould be aware of the need for hiring specialized security analysts to perform round-the-clock systems monitoring to secure their resources.

										Abstract: Dynamic Channel Allocation (DCA) technology is an effective ways to solve the contradiction between limited spectrum resources and increasing user demand in TD-SCDMA system. Aiming at the limitation of conventional DCA algorithm, an improved dynamic channel allocation algorithm based on carrier priority is proposed in this paper to solve tidal phenomenon caused by regional traffic migration and shows channel model. The simulation results show that the proposed algorithm can effectively increase resource utilization and improve access success rate with less changing in channel model.
