    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.
