Tools and Techniques in optimization of Network Resources

Any network, whether private or public is usually governed by a number of conflicting goals such as meaningful communication between the systems in a heterogeneous routing environment. Exchange of network meta-data for forwarding and routing, distribution of network resources for optimization and ensuring the quality of service (QoS), and sharing of network resources using heterogeneous formats of files are the other parameters. The above-mentioned goals are related to security and bandwidth. The other parameters are required for hardware with software compatibility in the implementation of different protocols. Especially, communication takes place in a real-life environment (i.e. consisting of multimedia and hypermedia files) carrying out the optimization. Such optimization of resources can be achieved using certain available tools and techniques. The paper consists of two parts: the first part is a survey of the tools of the trade and the techniques based on the optimal usages of the tools. The second part shows the implementation details of one of the techniques, for example, security in a particular layer such as transport/IP layer. The experimentation is to show that vulnerable ports can be closed by killing the processes using operating system tools to make the system secure.
