Introduction

In order to create proper network connection every organization must required effective data communication and network configuration to manage the IT infrastructure. With the help of this kind of configuration any organization have to set up advanced programming machine that will help the particular organization to build up web version for the machine. Biomedical development organization specifically produce or develop software for any kind of programming machine and the organization now is trying to make web version for the machine. The organization has almost 250 representatives with only 2 specific PC room.

Purpose

Purpose of this report is to investigate or figure out proper system administration for this organization. Apart from that another purpose of this report is to construct the network design by which it is possible to maintain the data communication in between a particular network.

Discussion

Network design for recommended network

Circuits

Basic goal of the organization is developed the web version for their machine. Therefore the organization needs to reconstruct their network configuration that are most upgraded and low in cost and flexible. Therefore the organization is going to configure upgraded network connection by which they can provide data communication.

Cat5 and cat6 cabling are better option but it all the wall jacks it takes heavy areas such a media room. Therefore Ethernet jack is the best option because it is most straightforward. With the help of Ethernet switches it is possible to connect with multiple device in the same place with the help of router connection. Apart from it allows all the traffics to pass as fast as possible and without any kind of interference. Therefore the organization can use this cable or Ethernet switches to connect with the network (Aggarwal and Lu, 2013, p.23). Apart from that gigabytes switch like Net gear GS108 can be used because with the help of this network speed will increase almost ten time in comparison with previous generation. Hence the organization must have to configure gigabit rated connection otherwise it is not possible to get maximum speed.

From the case scenario it can be constructed that one building of the organization have room for software programmers and for web designer and other buildings of the organization have the room for software developer and technical department. Hence, fast application response is mostly required in between all the building to transmit the data and other information in proper manner. In order to make proper cable connection between two buildings low latency and high bandwidth utilization is required. Only this kind of configuration can manage the high gigabit speed. With the help of this kind of network other department of the organization will also benefited.

Proposed circuit

According to the scenario it can also be constructed that use of optical fiber is another relevant option for the organization because with the help of this kind of configuration it is possible to transmit all data more efficiently it has the ability to recover the disaster. Main advantage of this kind of optical fiber is resource sharing efficiency and reliability. With the help of this kind of optical fiber cable data transaction and storage of data can transmitted more efficiently. Hence to use this kind of fiber upgrade VPN connectivity is also required. Otherwise it is not possible for the organization to maintain fiber cable connection. Basically use of optical fiber increase the speed of bandwidth almost 10 GB. Therefore it will help the organization to transmit every data from one machine to another machine (Desai et al. 2014, p.2000). With the help of this it is possible to reduce the network traffic. If the network traffic is reduced then all the incoming and outgoing packet data can be transmitted smoothly.

Hardware (Network and user)

In order to construct this kind of circuit and network technology proper hardware is also required for maintaining system. The configuration is generally constructed on the bass of usage of computer and the entire hardware device.

Generally for two kind of user different desktop configuration is required.

Heavy user

For all the heavy user high end application support is required specially for all the software developer, technical team high end configuration is mostly required. For heavy user required operating system required is windows 8 or 8.1 with 64 bit. Dual card video card is required for heavy use. 100/1000 GB network card is the best possible option for this. 64 Gb memory and CPU is i7.apart from the 500 GB hdd and dual monitors is also required.

Standard user

For the standard user that much high end configuration is not required. For standard user required operating system required is windows 7 with 64 bit. 10/100/1000 GB network card is the best possible option for this. 8 Gb memory and CPU is i5. Apart from the 250 Gb hdd and dual monitors is not required.

Switches

With the help of switches it is possible to maintain better connectivity in between layer 2. In case of hubs there is possibility of technical failure because in case of hubs in connected server collapse then it affects the entire system. Therefore with the help of switches it is possible to receive the connection from the server and forward network connection in between the entire designed computer. Most affordable and lost in cost is layer 2 architecture. In case layer 2 all the data transmitted from one device to another device very easily. In case of layer 2 major drawbacks is that if the network get too large then the efficiency of the particular network get reduced (Lu et al. 2014, p.1841). According to the current scenario it can be suggest that the organization is going to develop more web server programming machine therefore the utility of proposed network will be increased and according to the layer 2 concept it reduces the network efficiency therefore layer 3 is the best option. Therefore the organization need to configure more updated and effective switches that can easily identify maintain the connectivity in between the machine using proper hardware.

Router and firewall

After measuring all the condition the organization need to provide best router that will maintain the connectivity in between two buildings. Apart from the proper firewall is also required because with the help of incoming and outgoing traffic device is actually checked, hence it is possible to maintain the security in the network. In order to get better performance and to reduce the amount of specifically broadcast traffic layer 3 configuration is the best possible option mad for that the proper gateway router is the best option for the organization. The router connection will maintain and enables the VPN tunnels that enable telecommuters. The switching in this case must need to align in this manner so that it becomes possible for the router to support the VLAN or virtual LAN. In case of layer 3 it is possible to simplify the security management and at the same time it improved the fault isolation. Therefore the router connection in case of layer 3 must need to configure in proper manner.

Hardware configuration for proposed circuit

If optical fiber cable is used for maintaining the connectivity in between two buildings or multiple computes then layer 3 is the best option and the organization have to maintain some hardware configuration. In case of fiber optics the organization need to use additional SFP module that will connect all switches in between floors. Generally local area network or LAN uses the fiber optics as the backbone. In most of the cases LAN required longer distance than CAT5 or CAT6. Apart from that fiber offers higher bandwidth and it is possible to expand in future therefore most of the organization choose these options. High bandwidth and effective and reliable data transferring facility is most convenient option for optical fiber (Kuzlu et al. 2014, p.83). At the same time in layer 3 it is possible to reduce the network traffic and divide the network connection in sub network. Therefore c required hardware configuration is different for configuring this kind of circuit. Mainly high storage capacity required almost 80-120GB and at the same time high storage capacity required almost 2-4TB.

Logical and physical approach for the proposed network technology

In case optical connectivity at first proper path need to be selected and then appropriate data connectivity need to established via that particular path and in this way the DCC or digital cross connectivity can properly be established. After that the digital signal range or level is expanded via digital signal range or level with the help of optical carrier (Pahlevani et al. 2014, p.55). It performed in this way to achieve their cross connectivity. In order to evaluate the connectivity level of the proposed network it can be evaluated that it has basically two layer and that are physical layer and logical layer. From the optical communication it can be represented that in which way connection transferred.

After that from the below mentioned diagram, it is possible to understand the connectivity that are maintained in the physical layer. In case of physical layer the proposed network maintained the following parameters such as fiber demands, protection methodology, demand distribution and synchronous and asynchronous network.

All the parameters that are present in the physical layer provide some effective works and it will help the organization in various ways.

Fiber demands: it actually explain the number of nodes that means all the users

Protection methodology: with the help of protection methodology it is possible to protect all the links that are connected with the server. Server protection and path protection is the most effective for any organization. Therefore this network technology will support the organization from every aspect.

Demand distribution: it is another major approach in physical layer. According to this approach it consist both the direct and indirect combinations. From the concept of direct path all the source node is distributed directly to the receiver of reception nodes. In case of indirect nodes all the information is divided in sub parts (Esmail and Fathallah 2013, p.945).

Synchronous and asynchronous network: This approach actually suggests actually communication in real time. Apart from that with the help of synchronous and asynchronous network design it is possible to transfer the effective data from the sender to the receiver. In case of asynchronous mode the rate of data transfer is slow.

After this layer logical layer connectivity is introduced. From the below mentioned diagram it can be constructed that this kind of logical approach must contain all the following steps that are mentioned in the diagram.

Quality of services

Integration of Optical Network Design: with the help of this approach any organization can explain the network design in terms of graphs.

Channel utilization: with the help of this approach it is possible to maximize the band with the in between the sender and receiver. Apart from that it also provides path propagation in between the sender and receiver. Therefore this kind of approach is more effective for the organization.

Multihop optical network: with the help of this approach it is possible to maintain connectivity across the sender and receiver.

Node mobility and scalability: according to this part it can be suggested the actual network patterns and size of the network.

Spatial locality: according to the concept it can be constructed to providers actually all the information about the slot.

Resource sharing through optical channel: This approach actually cheeks the fairness in case of data transaction.

Optical channel capacity: from this part it can be suggested that in provide the connectivity in between sender and receiver nodes (Xing and Zhou, 2016, p. 240).

Quality of services: it provides actually every kind of connectivity in between the network.

In this way the proposed network logically and physically perform for any particular network and from this organization it is one of the best approaches because it help the particular organization to maintain their network connection in more effective way.

Software (Network and user)

According to the previous condition it can be suggest that for performing software related application work the organization can use Microsoft visual studio. With the help of this kind of approaches all the developers can manage programming, scheduling and debugging. Apart from that Microsoft project that can an also be used (Marquardt et al. 2016, p.34). In case of maintaining the finance related issue the organization required account related software. Apart from that for maintaining graphics related work the organization must require some software that contains graphics tools.

For proposed network software requirements

According to the proposed network infrastructure it can be constructed that all the software which are going to use in the organization system must need a direct or indirect connection with the layer 3 architecture and optical fiber connectivity. Therefore the organization can use Net suite software for financial purpose and all the upgraded version of the software which can perform in proper manner.

Proposed network layout

From above mentioned logical and physical network approach it is clear the proposed network connection will more flexible in layer 3 architecture because in case of optical fiber it sent all the data packages from sender node to the receiver node very smoothly and in some time it distributes the information in between two or more parts (Espina et al. 2014, p.221). Layer 3 is the best option as because in case of layer 3 it actually reduces the network traffic and distributes the connection in sub-nets. With the the help of proposed network it is possible to maintain the patch panel in between the entire floor. With the help of Ethernet connectivity with 10GB speed it is possible to maintain the connection in between all the computers that are used in the organization. There are almost 254 users in the respective organization. Therefore two subnet can be used to maintain the connectivity and with the help of VLAN it is possible to develop the performance of the network

Recommendation

Implementing fiber optics for maintaining the connectivity in between two buildings is more effective rather that VPN tunnel.

Use of layer 3 rather than layer 2 is more effective because with the help of layer 3 it is possible to avoid the network traffic.

High end storage server is better option rather than multipole server.

Cloud based sales and finance software is far better option rather than other software.

Conclusion

From the above discussion it can be deduced that network and data communication major side of any kind of organizations. In case of IT industry it is the most important part. From the discussion it can be deduced that optical fiber network cable is going to used to maintain the flawless connection in between two buildings and at the same time to create the physical connection in between the two buildings the proposed network connection is established. In order to establish the organization is going to reduce the VPN connectivity in between two buildings.
