Developing An Advanced Modern Distributed Networking System

Weaknesses are a symptom that is prevalent in today’s information technology realm, indicating vulnerabilities and risks that come hand and hand with shared networks like Aircraft Solutions. With enterprises exchanging an unprecedented level of information over open networks, the vulnerabilities and possibility of compromised security by unwanted intruders is swelling up into a new type of beast.

A successful IT system is something that is composed of several different functional components to make it a whole. It takes each component to efficiently work so that the entire system runs smoothly. When one or more parts of the system are not properly working it can affect the entire IT system as a whole and render it completely vulnerable to people with malicious intentions. In this paper I will discuss the role of each component in it and shed some light as to why each is needed.

The network diagram of Global Finance, Inc. (GFI) depicts the layout of the company’s mission critical systems. The company has two servers (Email and the Oracle database) which are used more than any of their other systems. GFI heavily depend on their network to be stable because of their financial systems that are running and any outage would negatively affect their operations and financial situation. Like all other business, customer satisfaction and the security of GFI’s network is crucial. In order to ensure their network and data is secure,

keep track of its state.If the first node fails, the second node takes up the operations from where the

The reliability of a system can be improved through the introduction of redundancy in the system. Some of the examples of redundancy in the operation are as below:

The networking of the system is recommended after a system study and the fact that there has been a 100% expansion of the demand for the system- from 5 to 50 have been noted. It is also shown that as of now there are machines that are stand alone with windows 7 operating system. The task is to provide a network connectivity that would provide direct connections between the employees, and be centralized in the operation. This essentially requires the creation of a network. This means that all the computers must be installed with a network card and this would be the case with windows 7. The question then comes is if there must be windows networking or use other protocols. We can also partly use the most modern practical solutions.

Information will only have value if customers can access it at the right times. Availability can be affected by system errors, and malicious attacks as well as infrastructure problems. Availability is ensured by maintaining hardware as well as repairing hardware immediately when need arise. A correct functioning operating system should also be maintained in the environment free of software conflicts. Adequate communication bandwidth should also be addressed as well as preventing bottlenecks from occurrence.

A goal of redundant topologies is to eliminate network down time caused by a single point of failure. All networks need redundancy for enhanced reliability. Network reliability is achieved through reliable equipment and network designs that are tolerant to failures and faults. Networks should be designed to reconverge rapidly so that the fault is bypassed.

Network reliability is the ability of a network to maintain or restore an acceptable level of performance during network failures by application various restoration techniques and prevention of service outages from network failures by applying preventative techniques. (Network Survivability, 2001). Computing the reliability of a network is quite difficult; therefore estimation by means of simulation is a popular choice for determining network reliability.

In contrast, Cisco Layer 2 Resiliency advantages are claimed to offer rapid failover without service disruption. The layer 2 is designed to streamline change management and service turn-up without WAN disruption with fewer errors. It offers a high availability through real-time recovery and resiliency at the network, device and design levels. Cisco Layer 2 Resiliency offers increased system redundancy at the platform level, network security through access layer defense, identity-based trust, pervasive security and management as well as providing device posture assessments. Operational efficiency is achieved through automated configuration, proactive diagnostics and simplified troubleshooting. This is designed to provide predictable application performance to support converged applications as well as support IP multicast for new applications.

With the increasing dependency on wireless networks, the need for proper reliability analysis for Mobile ad hoc networks (Manets) is also increasing. Failure of Manets in areas like warfare, nuclear reactors, medical equipment and airplanes can lead to catastrophe. Unlike traditional networks, measuring the reliability of Manets is a tedious task as it involves dynamically changing topology. The existing methods for calculating reliability use two terminal analysis as the basis for calculation. It uses the same method used for traditional computer networks to calculate reliability. However, the method is not very efficient when it comes to the wireless networks as they are far different from traditional networks. It is also a time consuming task to identify all the nodes and links in a wireless network as nodes move freely in the network. In This paper, We are going to discuss about NLN(Node-Link-Node) technique which reduces the complexity of analyzing the reliability in Manets.

Safety of information is the most valuable asset in any organization particular those who provide financial service to others. Threats can come from a variety of sources such as human threats, natural disasters and technical threats. By identifying the potential threats to the network, security measure can be taken to combat these threats, eliminate them or reduce the likelihood and impact if they should occur.

Now a day’s Information Technology plays an important role in every field whether it is in big Multinational companies, or in Hospital or in school, colleges, bank etc. It is having a wide range. Every field is now a system oriented where each and every person should have knowledge of basic computer. Information technologies also important to beat the competition in various industries. In our survey report we are going to survey and test the reliability of hardware, networks and software in information technology field. Information technology is a combination of Hardware, software and Networks. It is an combining of technology, users and

Cross-Fault Tolerance (XFT) is new trending protocol that makes BFT more feasible and efficient, also attack model is simplified. [17] Most of the BFT protocols believes in adversary which is used to handle compromised nodes, also message delivery of entire network. To handle such a powerful adversity results complexity and therefore becomes less efficient. To overcome this issue XFT is used to provide perfect service as long as replicas are perfect and communicates with each other continuously. Same number of resources are uses as used by protocols that can handle failures and also can

These solutions were based on performing se- lective server replication and intelligent client reassign- ment, where the victimized servers were turned into moving targets in order to isolate attack. The attacked server instances are replaced with new replicas at dier- ent network locations and subsequently the clients are migrated to the new server instances. The new locations are only known to clients that have been
