Question:
Discuss About The Network Fundamentals To Network Management?
This report is about the designing of local area network in an organization however there are three major departments in the organization namely general support, marketing, and sales departments. These departments will be interconnected together to form the local area network; however since they are in the separate floors each department will have its network segment and then will be joined together [1].
The network to be installed will require to have access to internet therefore internet access devices will be installed in each and every network section, to enable the intranet services in this network there will be all network will be configured and a WEB/HTTP server will be installed and it will be located in the general support department .
However the network will require support of email services the network will be installed a E-Mail server and will also be located in operation department.
Below is the design for the recommended local area network.
The local area network as shown in the above network design diagram indicates the connection made between the various network segments. During the network design there was wiring that was done to link the various components, however the equipments used for the network wiring includes:
The wiring cannot be complete without use of the switch devices, however these devices has a total of 24 ports and therefore allow the connection of many devices to it, however the switches were used in each department where two or one switches were linked to one switch in order to accounting the number of devices in that section in the general operations there were three switches where two were used to connect the computer end devices while third one connected to the network router [2].
The sales department there was also three switches used to connect the end devices and the router connected to the router, while in the marketing department there were two switches one used to connect the computers and the other one connected the computer’s switch with the router,
The routers are other types of devices and they are connected to the switches that form the departments subnets ,however these routers are then linked to other routers in the other department which will from the entire Local Area Network and through these routers users in the different network can communicate through E-mail or intranet connections.
These are other components that are used to connect the end devices to the switches or the switches to the routers they have the male and female jack connection according to the type of the connection.
The access point were used to do the internet connectivity to the users where each department was allocated the a internet access point to enable internet connections.
The fiber optic cables are also used to do the connection between the departments routers, this will help to offer a high speed internet access and hence better internet and intranet connectivity.
The optic fiber cable was recommended to be used for the connection between the departments due to the following reasons.
The fiber optic cable will enable quick and simple transmission of data since it can carry more data than any other type of medium. Copper cables were originally designed for voice transmission and have a limited bandwidth [3].
The fiber optic cable uses the light principals to do data transmission and its transmission speed exceed the one for the cat 5 and 6 since the signals hardly get degraded during the transmission.
The fiber optic cables also are good since the data signals can be transmitted for very long distance without loss for even 25kms.
The fiber optic cable cannot be affected by variation of the climate or change in temperature and also there are no chances of having interference since it do not transmit signals electronically therefore it posses more reliability in the network.
In case the network expansion the fiber optic cable will be easy to extend and the current network will also be included without any network failure.
The cat 7 Ethernet cable is a type of cable that was used to connect the computers ,and the internet access points to the switches in the different departments which are then connected to the routers .However this type of cable was used due to the various advantages associated to it.
The cat 7 Ethernet cable has high speed and rate in terms of transmitting the data in various locations where it can be able to transmit at a rate of 600MHz.
This cable also has other properties where it is bale to shield any interference which is external and thus no chance of distorting the data signals.
The network cable is more strong and no one can be able to bend it and thus it is safe from any physical damage .
This Ethernet cable has a very long life span where it can be used for more than twenty years without any damage unless the network will be upgraded or changed.
This network cable is also very good since the upgrade from the old version of cables do not require replacement but it needs the connection since this cable is compatible with all network cables
The local area network design will require a topology that will guide on the physical layout of the local area network however, there will be also the protocol used that will be guiding on how the network components will be communicating with each other. Below are the respective topologies and protocols [4].
This is the psychology that will be used, this is because the network in the department level is in star topology which is made after linking the end devices to one router then all these routers are linked to the routers which are then linked to the other devices to form a ring topology as in figure below.
In this network will however use FDDI type of network protocol where the three different departments has routers that link them then since all these routers are linked to each other in a circular manner the resulting protocol is FDDI which is represented by use of two rings and since it is appropriate for long distance it will fit this network [5].
This protocol is appropriate since there will be data transmission even after the network breakage since signals will be transmitted through the next ring which is not broken, however this network is also best due to speed of up to 100MBps because it uses the fiber optic cables [7].
In order to install the network there is need to have a map of the plan; this will indicate the location of the various devices in the floor of the three departments [6].
Below is the diagram of the physical plan of this network:
Conclusion
The organization local area network designing takes various aspects where there are three segments of the network where the second floor is the general operation department, while the second first floor is the marketing and sales department.
This network is implemented by joining separate network segments for all these networks where each segment has a network router that connects to the other networks, however the major network components used for wiring and connection is the switches which links the computers in the department level ,routers that connect the network to other departments ,and RJ-45 jack pin that was used to link the devices to the switches or routers,
However among the cables used were the fiber optic cable that was used to link the routers to the other departments and the cat 7 Ethernet cables that was used to link switches to the routers and then end devices to the switches.
For the purpose of implementation the hybrid topology was used where the switch connected the departments in a star topology and then the routers were connected as a ring hence the topology used is the hybrid topology, however the Fibber Distributed Data Interface network protocol is the topology that was used to guide the network communication and the most important thing is it speed which is quite high.
Therefore the network is very important for every organization since it assists in the process communication, internet access, E-mail services and sharing of other resources in the network in order to cut on the operation cost.
