Question: Discuss About The International Journal Advances Information? Answer: Introduction The report gives an overview of the wide area design created for the connecting the different offices of Arr Company. A local area network is designed and a discussion is given on the cabling plan and type of connection used for the local area network. The type of topology used for the network is also discussed and each of the floor of the office buildings are analyzed for the creation of the floor plan. The network solution is designed by analyzing the requirement and the number of hosts required to be installed and enabling the users to communicate with each other using the network solution. For designing the network diagram Cisco packet tracer simulator software is used and the floor plan of the head office is created in Microsoft visio. Potential Concerns related with the connections There are different potential concerned that should be analyzed for increasing the efficiency of the network design and reduce the response time of the proposed network solution. The installation of the network device near the power lines, motors and other sources can cause electromagnetic interferences and thus degrade the quality of the signals and cause error in the transmission. The network should be designed with redundant links such that if a link is broken the secondary link can be used for backup for transmitting the data packets in the network. There are many security related issues that needs to be resolved for securing the network and restrict the access of the unauthorized users to connect with the core components of the network. The network administrator may face difficulty while management of the network resources distributed in different location of the network. There are other potential concerns that can affect the network such as cost, administrative time and the fai lure of the file server installed in the network. The network is designed to remove the complexity such that it can save the effort of the technician to resolve any problem associated with the maintenance of the network. The connection between the offices should be secured and some encryption algorithm, must be applied such that if it is accessed by any third party agents it would not be recovered and thus cannot use for illegal activity. The wireless access point installed in the network should have proper protection such that it cannot be access by unauthorized users. The servers connected in the network should be configured to group the users and manage the printing jobs for better management of the users and the network resources. A network monitoring tool should be used for the analysis of the flow of data packets and protect the network from distributed denial of service attacks. Discussion on the local area wiring The main physical property of the local area network are the network interface cards and the cables used for connecting the computers in the network for communicating with the other users connected in the network. Twister pair network cables are used for connection and wireless access points are installed at each of the floor for allowing the users to connect their wireless devices in the network. Some of the LAN equipments such as the bridge and repeaters are used for extending the network and separate them from another network. The capacity of the transmission is also important for increasing the efficiency of the network solution and direct connection should be used for connecting the network devices installed in the network. The network backbone should be fiber optics cable for connecting the different offices in the network because it allows higher bandwidth and is best suited for long distance transmission. Different types of cables are used for interconnecting the routers, switches and the nodes connected in the network. There are different types of cables such as unshielded twisted pair, shielded twisted pair, multi-mode fiber and single mode fiber for local wiring. The interconnection between the routers are done using the serial cables and cat 6a cables are used for connecting the layer 2 switch with the router and for local distribution purpose the cat 6 cable is applied. The cat 6a cables operates in the frequency of 500 Mhz and has the support for 1000 Mbps Ethernet and 10 Gbps Ethernet connections. The cat 6 cable is used for reducing the cost of cabling because its price is less when compared with the cat 6a cables. Discussion on the type of local area network topology Two types of network configuration are applied for designing the network solution for Arr Company, such as peer to peer network and client server network. The peer to peer network is designed for each of the departments that have less number of users and where security is not the main aspect. Each of the users connected in the peer to peer network can share their files and documents easily without any restriction acting on them. The client server network is used for the management of the wide area network where a central server is installed in the network for storing the files in the server and controlling the access of the other users. High level of security can be implemented and the server should have high end configuration for supporting the virtualization and balancing the load of the network. The local area network is designed following the star topology and a central router is used for each of the department for connecting the nodes installed in different location of the offic e building. The star topology is selected because different medium can be used for transmission of data packets in the star topology. Separate cables are used for establishment of connection between the device and the central switch and thus if a device fails it does not affects the performance of the network. A backup plan should be available for the central device because it is the main element of the network, if it fails the whole network would stop working. Each of the department of the organization are connected using a separate VLAN configured on the switch used for providing connection to the users. Since it is a large organization many data are generated in the network and there is a risk of collision between the data packets in the network and the data may get lost. Thus the creation of the VLAN would help to create separate channels for transmission of the data packets in the network and increase the efficiency of the network. Floor Plan for the companys head office The office buildings of Arr Company is located in different location of the suburb and a wide area network connection should be used for the connecting the offices. Local server are installed in each of the building for serving the needs of the users. The head office of the company is located in Melbourne CBD in the top three floor of a building for three departments namely: general support, sales and marketing. The first floor needs a LAN for connecting the 32 workstations, the second floor needs LAN for connecting the 20 workstations and the third floor needs the local area network for connecting the 38 workstations. Each of the LAN should be configured with IP address and subnetted for reducing the wastage of the IP address. A central router should be installed in the network for connecting all the three departments and configured with IP route for enabling communication with the other offices. A layer 3 switch should be connected with the router for creation of VLAN and minimize the impact of the potential problems identified for the development of the network solution. A same layout is followed for each of the floor for the development of the network solution. The head office of the company should be connected with a strong backbone and the network servers should be installed in the DMZ zone and the physical access should be restricted. Conclusion From the above report it can be concluded that for the development of the network solution and analysis is made on the structure of the building, floor plans and the number of workstations and servers required for each of the department. For the preparation of the network solution a wide area network and a local area network is designed. There are some potential concerns related with the connection between each of the departments and they are also discussed in the report. The wide area network is designed for connecting the different offices located in different location of the suburbs and the local area network is designed for connecting each of the departments in the office. For designing the wide area network for the company separate cluster is used different VLANs are allocated for each of the cluster for increasing the security of the network.
