Local Area Network and Wide Area Network Performance Evaluation

Cloud Crushers Company uses both wired and wireless technologies to ensure connectivity of its various devices and employees. In each regional office of the company, the network is designed to use Ethernet connectivity. In this Ethernet network, cables like twisted pair are used to connect between devices and optic fiber used for the backbone connections and then to the switches or hubs.

Service Types & Impacts

ISP connectivity service types such as DSL, CATV, or FTTH (Fiber to the Home) can dictate what options are available for connectivity when designing or upgrading a network infrastructure. For example; a DSL connection or digital subscriber line utilizes an existing telephone line. The speed and performance of DSL can dictate the option for connectivity. DSL is distance dependent, meaning the further the business is from the DSLAM (DSL Access Multiplexer), the lower the data rate. CATV or Community Access Television known as DOCSIS 3.0 provides faster data speeds that DSL. DOCSIS 3.0 provides data rate ranges of 300Mbps download and 100Mbps upload. FTTH or fiber to the home also known as fiber to the premises is a faster technology than DSL and CATV. FTTH provides data rates up from 1Gbps to 10Gbps.

ISP Connectivity

Fiber-to-the-Home (FTTH) is an ISP connectivity that requires a connection to a fiber enabled modem in order to access the internet. This dictates the options for connectivity in that it is not limited by the fiber but by the terminal equipment hence allowing improvement of some speeds by upgrading the equipment. CATV on the other hand is limited to an impedance of 75 ohms and its connector is type F (Trivedi, 2013). To be able to access the required services in a particular location, distribution lines should be present on the region’s poles.

How the Options Change

Businesses in various industries require heavy usage of internet by allowing customers to view and order their products through online platforms and websites. Some of these websites are inaccessible due to the connectivity type. For small businesses or even personal uses, the network can be perfectly acceptable with simple connectivity such as DSL or dial-up. However, large organizations like Cloud Crushers needs robust network connectivity utilizing fiber optic cables. With the increase in the network robustness there are increases to cost. For example, use of fiber optic is expensive as compared to dial-up (Comer, 2015).

Conclusion

Proper and fast connectivity is the key to CloudCrushers success, and providing the proper coverage will ensure they succeed. With the implementation of fiber and MiFi hotspots, along with remote users high-speed connections, CC will have the necessary access to their cloud platform, further allowing them the access they need to their data. The retraction of a WAN environment is possible since all resources are located in the cloud, further reducing the cost of operation. Finally, with this setup, CC can increase productivity and increase profits.
