CIS 175: Network + Guide To Networks

November 04, 2013 After analyzing the network system that is presently being used I would recommend moving to a star network topology and using cat5e cables for the network. The star network has the advantage of adding nodes or work stations as the business grows. When it comes to monitoring and troubleshooting the system, it is made easier due to the centralization of the hub/switches. The reliability of a star network is another advantage to the company. If one node or workstation fails in the network the rest of the network is affected by the failure. While the star topology has many advantages it also has some disadvantages. The star utilizes a central location for the hub/switch so if it fails the entire system is down. By adding a backup hub/switch this issue can be minimized in the event of the main hub/switch failure. The initial cost of equipment can also be a concern. The cost of the hub/switch will run about $750 to $1800 for each hub/switch, if you add a backup that price will be $1500 to $3600. Depending on the work station NIC cards you may need to upgrade to new cards that accept the Cat 5e cable. I would recommend installing Cat 5e or Cat 6 (speeds up to 1000 Mbps, 1 gigabit per second Gbps) twisted pair cables rather than using the coaxial cable. The twisted-pair cable is designed for telephone communications and modern Ethernet networks. The pairs of wires are twisted to give protection against crosstalk; crosstalk is interference of noise generated by adjacent pairs. Just like any electrical wire a magnetic field is produced when current flows through it. By twisting the wires together in pairs the magnetic fields will be opposite of each other and while null or cancel out. Two basic types of twisted-pair cable exist: unshielded twisted pair (UTP) and shielded twisted pair (STP). The UTP cable contains pairs of copper wires that are covered with an insulating material and then are twisted around each other to help with the cancellation of crosstalk. UTP cable has a few advantages, one of which is the size. Due to its small size in can be run easily through duct work or in the ceiling and allows you to install more cables in wiring ducts. UTP is compatible with most network systems and is easy to install and the cost be foot is less than other cable types. The other cable type is (STP) and is the same as UTP but is shielded. Four pairs of wires are wrapped with a metallic braid or metallic foil to protect from crosstalk. The added protection makes the cost of STP more expensive compared to UTP. STP is more difficult to install, if not grounded properly the protective shield will act as an antenna and pick up unwanted signals. Because of this STP and the cost it is not normally used in Ethernet networks. The distance of cable length of Cat 5e or Cat 6 is 328 feet compared to the thousand feet of the coaxial cable before the transmission strength begins to diminish. This can be overcome by adding a switch or repeater to boost the signal which will cost about $65.00 each. That would add to the cost depending on how many are needed. The cheapest way to buy the Cat 5e UTP cable is in bulk and will cost around $83.00 for a thousand feet of the cat 5e standard cable and the male ends. The other cable type is fiber optics. Fiber optic cables are strands of insulated glass that transmit information using pulses of light. The cables are for long distances and very high bandwidth network communications. Fiber optics offers extremely high bandwidth and resistance to the electrical interference and also has a data security advantage being the data cannot be detected during transmission. Fiber optics sound great but does have some disadvantages that come with it. For one it is more expensive and requires special tools and test equipment to install and maintain the network. You must also consider the fact that it is made of glass which means it can be easily damaged so care has to be taken on where the cable is installed and during the installation and trouble shooting. While fiber optics transmits more data and is less susceptible to electrical interference, the added performance increases the cost to $500 for thousand feet plus the cost of the cable ends. My personnel recommendation would be to install a star network due to the performance and reliability. As I stated earlier the hub/switch would need to be upgraded and the length and size of the network could be increased or decreased if needed. I would also upgrade to the UTP Cat 5e or Cat 6 Ethernet cable due to its cost, reliability and easy instillation. The STP cable is an over kill and would be a waste of money. I would not even consider fiber optics because of the tradeoff of cost that comes with the performance. If you have any questions or concerns please feel free to contact me anytime.

...THE BENEFITS OF TWISTED PAIR CABLE Recommended Changes and Benefits As I am a consultant for NCF, the Networking Consultant Firm and my first assignment are at Ocper, Inc. We will first study to their current networking and current technology that they are using. First, they have use coax cable to connect 20 windows peer to peer computers. The president had told me that he expect his company to be expand and double in size, in the next two years. What NCF will recommend is to take a closer look at benefit of twisted pair cable. Since the business now needs to connect 20 computers, I would explain how twisted pair cable will help them. Cable is the medium through which information usually moves from one network device to another. There are several types of cable which are commonly used with LANs. In some cases, a network will utilize only one type of cable, other networks will use a variety of cable types. The type of cable chosen for a network is related to the network's topology, protocol, and size. They need to be more understand their current situation so; it could help them to get the highest performance from it. The twisted pair cable come with in two varieties; shielded and unshielded twisted pair....

...Benefits of Twisted Pair Cable Gregory M. Dowell CIS 175 Professor Blanson November 3, 2013 Benefits of Twisted Pair Cable Ocper, Inc. is a company that currently has twenty employees connected in a peer-to-peer network. Over the next two years they are looking to double in size and are looking for a solution to their computer networking needs but are weary of any drastic changes. Currently all of their computers are connected using coaxial cable. Through this paper I will show the benefits of changing their network configuration, as well as replacing the coaxial cable with twisted pair or possibly fiber optic cable. My fist suggestion is to reconfigure their network from peer-to-peer to a client/server network in a star configuration. By doing so, there will be a central computer used as a server that would facilitate communications and resource sharing between the other computers on the network. With this server clients will be able to share data, data storage space, and devices such as printers. The users will still be able run applications and save data to their own computer, but will also have the option to save it to the server (Dean, 2009). Saving the data to the server will enable better security of the data since backups to the system can be scheduled every night. In addition, each client can be authorized only the access to the applications they need....

...Suggestion of Changes In Terms of the Current Network Type/Structure with the Benefits. I would advise the president to replace the current network setup to twisted pair cable. Coaxial cable carries high frequency signals along a single center conductor, whereas, twisted pair cable improves its electrical characteristics at a lower voice frequency and prevents signals from crossing into adjacent wires. It also allows the signal to travel longer distances. Reasoning for Suggesting Connecting All Current and New Client Computers Using Twisted Pair Cable Instead of Staying With the Current Coax Wiring Structure. Twisting two insulated wires together improves their electrical characteristics at a lower voice frequency and prevents signals from crossing into adjacent wires. It also allows the signal to travel longer distances. Coaxial cables carry high-frequency signals along a single-center conductor surrounded by a foil or braided copper shield. Coaxial cable has less loss than twisted pair, and the shield protects the signal from interference. There are two types of twisted pair cable, shield and unshielded. Unshielded twisted pair, or UTP is so closely identified with Ethernet implementations that it is often called “Ethernet cable.” This form of cable can contain any number of wires, but the most common form used for networks contains eight wires, configured as four pairs, with...

...Unshielded Twisted Pair – A pair of copper wires twisted together with no electromagnetic shielding around them. Each wire pair is twisted many times per foot (higher grade UTP cable can have more than 20 twists per foot). The twists serve to cancel out the electromagnetic interference that the transmission of electrical signal though the pairs generates. Shielded Twisted Pair – A type of twisted-pair cable in which the pairs are enclosed in an outer braided shield, although individual pairs may also be shielded. The pairs in STP cable have an individual shield, and the individual shielded cables are wrapped in an overall shield. The advantage of STP cable over UTP cable is that there is less attenuation at higher frequencies and is less susceptible to EMI. Fiber-Optic Cable – Fiber-optic cable uses a strand of glass or plastic to transmit data signals using light; the data is carries in light pulses. Unlike UTP/STP, the transmission techniques are not electrical in nature. Plastic-core is easier to install than traditional glass core, but plastic cannot carry data as far as glass. Dark Fiber – When telecommunication companies first run the fiber-optic cable, they don’t run the exact number of strands that they need. They install two to three times as much as they require. The spare strands of fiber are called dark fiber because they are not in use. The Dark Fiber usually lease out these lines to other companies. Coaxial Cable – Also called coax cable....

...Introduction The company Parstech is undergoing a change in infrastructure. There are several changes which were suggested by the top management. The cost of branch communications should be reduced by using current technology. Besides that, services to be online to make it easier to fix errors. The online services need to be extended up to international level. There should be security for the now-online services. Online services (troubleshooting and maintenance) should be able to continue its operation on 24/7 basis without interruption. Finally, existing technology should be used as much as possible to save cost. Based on the existing technology, it is known that the corporate MAN connection makes use of lease lines. In the office buildings, LAN connection with hybrid bus/star topology is used with Ethernet LAN transmission medium. In the new Network Design, a few additions are present. Figure 1 - Parstech Wide Area Network This network design shows the Wide Area Network and the relationships between the branch offices and the main headquarters. The main headquarters is where the application servers of the company is present. This is to enhance security by placing it in one place.
