Computer Network Infrastructure System †Free Samples to Students

Question: Discuss about the Computer Network Infrastructure System. Answer: Introduction A computer network is the infrastructure and it used to allow more than one computer to communication with each other. This process is achieving by providing the collection of communication rule is called as protocols. The Protocols are observed by participating hosts. The collection of network protocol rules are includes the following characteristics of the network such as data transfer speed, access method, cable types and physical topologies. The Network protocols are listed below ("A brief explanation of computer network protocols", 2017). ATM Token ring Local talk Ethernet FDDI The M2M solutions contains the six building. Each building has the various departments. The Building are connected with the network by using router. The M2M solutions proposed network infrastructure provide the high efficiency and scalability of the network. It using the network analysers to reduce the troubleshooting problems. The company contains the 1200 work stations. These are divided into six building. Six building are Head office, Information technology, Sales office, transport office, finance office and research office. The Proposed network infrastructure is will be discussed. It use the network analyser tool that is wireshark to reduce the trouble shooting issues in the network. The Current company policies does not allow the network analyser tools for the network. But the network Analysers tool provides the effective network. So the Company management team interested to using the network analyser tool. So gives the network analysers proposal for company board. So the staff are analyse the best network analyser tool and their features, benefits, recommendations and how it support the proposed network infrastructure. These informations are once gathered and then it provided to company board. The network analyser tools are will be discuss (Callahan, n.d.). The above diagram display the M2M solution network infrastructure. M2M organization contains six building. Each building connecting the network by using the router. The company has the 1200 work station in six buildings. It contains the following departments such as head office, sales office, research office, transport office, information technology office and finance office. Each department has the workstations like the head office contains the 60 work station, finance office contains the 260 work station, information technology office contains the 520 work stations, research office contains the 120 work stations, transport office contains the 130 work stations and sales office contains the 40 work stations. Every work stations are connect with router. The Proposed network infrastructure using the following components ("Chapter1.Introduction", 2017). They are, Cisco routers Cisco Switches Cisco Core switch Cisco application server Cisco authentication server Cisco main Server PC Printer The cisco products are used to provide the effective network. It reduce the business costs. The Cisco products are also support the medium size organization. It provides the high security and scalability of the network. M2M organization network infrastructure IP addressing for each building is shown below ("Five free network analyzers worth any IT admin's time", 2017). 0.0.0/22 (Building 1) 1.0.0/22 (Building 2) 2.0.0/22 (Building 3) 3.0.0/22(Building 4) 4.0.0/22(Building 5) 5.0.0/22 (Building 6) The above IP address for each building provides the 1024 hosts per network. The network analyser is a set of hardware and programming that can be installed in a computer. It is used to enhance the protection from the malicious activity. It support the anti-virus, firewalls and spyware detection programs. The network analysis is the process of capturing the network traffic to find what happens on the network. It display the network traffic in human readable format. Role of Network analyser The network analyser provides the detailed statistics for recent and current activity on the network ("Network Analysis - Colasoft", 2017). It detect the unusual levels of network traffic. It identify the destinations and sources. It monitor the bandwidth utilization. It display the all statistics on a user friendly. The Network analyser is used to define the conventions and rules for communication between the network devices. It include the device mechanisms to identify and create the connection with each other. It also specify and formatting the data. It support the data compression and message acknowledgement for high performance. The network analyser using the packet switching techniques to send and receive the messages. The network analyser easily detecting the compromised computer and discovering the faulty network card. It prevent the cyber-crime from the network intrusion detection. It easily analysis the applications operations. The M2M organization current policy does not allow the use of network analysers. But the network analyser tools provides the efficiency in network troubleshooting processes. The Most power network analyser is Wireshark. It is used to capture the network packets and it provide the packet details ("What's a Wireshark Network Protocol Analyzer?", 2017). The network administrators are using the wireshark for network troubleshooting problems The network developers are using the wireshark to debug the protocol implementations The network security engineers are using the wireshark to examine the security problems ("Network Protocol - Types of Network Protocols", 2017). Features of wireshark It support the windows and Linux. It create the various statistics. It saves the captured packets. It easily import the packet data to text file includes the hex dumps. It capture the live packet data from the internet (Sanders, n.d.). The wireshark is a protocol analyser and it used to solve the network problems. The hackers are using the wireshark to hack the computer. The wireshark is the ability to capture the network traffic in the network. When trouble shooting problems are occur most of the professionals are using the black approach but it does not provides the effective network. So provides the effective network by using the wireshark. It check everything in the internet site and computer. It capture the network traffic being exchanged by out computer and network. The hackers also using the wireshark to hack (Shimonski, 2013). The most network protocols are designed for security but the HTTP, TELNET and FTP protocols are non-secure protocols. The wireshark capture your login session that is user name and password. So the hackers are easily hack another computer user name and password. Recommendations The Proposed network infrastructure using the network analyser tool to provide the secure and effective network ("What is network analyzer (protocol analyzer or packet analyzer)? - Definition from WhatIs.com", 2017). The Best network analysis tool is wireshark. The wireshark is used to provide the effective network to solve the network issues. It capture the network traffic from the network. So M2M organization decided to use the wireshark network analyser tool to reduce the network problems. The organization team members are fully analysed the wireshark tools and provide the information the organization board. The M2M organization using the wireshark tool to provides the scalable and flexible network for the staff. It helps to optimize the business costs.
