Math233 Unit 1to Communicate Most Effectively Network Administrators

Math233 Unit 1 to communicate most effectively, network administrators attempt to maximize bandwidth and throughput speeds to achieve high data transmission rates within the building’s CAT5e cables. These performance data transfer rates are given in multiples of unit bits per second (bps). In the table below, the school’s IT department estimates the network throughput that is required in the near future. The network manager has asked you to use these data to analyze the current traffic load and the network's overall capacity. Estimates given in the table below suggest that your network throughput can transfer Gigabits (Gb) of data in seconds for each user.

For each question, be sure to show all your work details for full credit. Round all numerical answers to three decimal places. 1. Research and define the concepts of maximum theoretical throughput, channel capacity, and bandwidth. Next, explain the difference between CAT5e and CAT6 Ethernet cables. What specific speeds can each of these cables handle? Listing credible cited resources, please answer these below.

2. Given that the throughput is the table’s Gigabits per seconds (Gbps), calculate and record this transfer rate for your chosen values with the formula: Table A: Estimates of bit-transmissions and times Seconds Gigabits (Gb) .. Your school’s maximum network bandwidth is 1 Gbps. Does your answer from above exceed that or not? Based strictly on your value, do you think the maximum bandwidth should be raised? Will the network infrastructure need to be upgraded to support CAT6 cables? How did you arrive at this conclusion? Include the factors that influenced your decision.

4. According to your research, the school’s throughput speed R ( t ) in Gbps, with respect to time in seconds, is best modeled with the rational function: Generate a graph of this function using Excel or another graphing utility. (There are free downloadable programs like Graph 4.4.2 or Mathematics 4.0 ; or, there are also online utilities such as this site and many others.) Insert the graph into the Word document containing your answers and work details. Be sure to label and number the axes appropriately.

5. Peak Measured Throughput (PT): Peak or instantaneous throughputs (PT) measure values useful for systems that rely on bursts of data in a CAT5e cable. Unlike continuous streaming, information travels in short bursts. For example, during in-class demonstrations, a computer lab’s user experiences high traffic usage spikes on a very high-bandwidth that is transmitted over a relatively short period of time. Activity is important during these in-use peak times. Peak rates are measured limits taken with respect to throughput as time approaches zero. So for the above function, use algebraic techniques to find: Based strictly on this result, do you think your school should raise its current network’s bandwidth of 1 Gbps? How did you arrive at this conclusion?

6. Maximum Sustained Throughput (ST): One of the most accurate indicators of system performance for high duty cycle networks is the maximum sustained throughput (ST) averaged over a long period of time. This value measures the network capacity fully utilized over its entire existence. Essentially, high volumes of continuously streamed transmissions max out the amounts of data being transferred in because the network is busy processing current data and unable to efficiently enter the cable. This builds up the delivery time causing latency instabilities. In this case, sustained rates are measured limits taken with respect to throughput as time increases towards infinity. So for the above function, use algebraic techniques to find the following: Based strictly on this result, do you think your school should raise its current network’s bandwidth of 1 Gbps? How did you arrive at this conclusion?

Paper For Above instruction

Effective communication of network performance metrics and infrastructural decisions is crucial for maintaining efficient data transmission within organizational environments such as schools. Network administrators target optimizing bandwidth and throughput to ensure high-speed data transfer, particularly within Ethernet cabling standards such as CAT5e and CAT6. A clear understanding of the concepts of maximum theoretical throughput, channel capacity, and bandwidth, along with the technical distinctions between different Ethernet cables, informs critical decisions on network upgrades and capacity planning.

Understanding Key Network Concepts

The maximum theoretical throughput of a network signifies the highest possible data transfer rate under ideal conditions, limited by the physical and technological constraints of the medium (Kurose & Ross, 2017). Channel capacity refers to the maximum rate at which information can be reliably transmitted over a communication channel, as defined by the Shannon-Hartley theorem, which incorporates bandwidth and signal-to-noise ratios (Shannon, 1948). Bandwidth, in the context of networks, describes the range of frequencies that a communication channel can carry and is directly proportional to the maximum potential data rate.

Ethernet cables such as CAT5e and CAT6 differ primarily in their construction and transmission capabilities. CAT5e supports data rates up to 1 Gbps over distances up to 100 meters, primarily designed for gigabit Ethernet, while CAT6 provides enhanced performance supporting speeds up to 10 Gbps over shorter distances of up to 55 meters, and 1 Gbps over 100 meters (IEEE, 2018). The improved specifications of CAT6 include better insulation and twisted pair designs, reducing crosstalk and electrical interference (Lu et al., 2015).

Calculating Network Throughput and Bandwidth Analysis

To evaluate whether current network throughput meets demand, we calculate the transfer rate using given data in the table; for example, if a user transmits 10 Gigabits over 5 seconds, the rate is calculated as 10 Gb divided by 5 s, yielding 2.0 Gbps (Gigabits per second). Comparing this with the maximum infrastructure capacity of 1 Gbps indicates whether an upgrade is necessary. If the calculated rate exceeds 1 Gbps, the network's bandwidth should be considered for enhancement.

Suppose the calculated transfer rate is 2.2 Gbps, surpassing the current 1 Gbps limit. This suggests that the network would benefit from infrastructure upgrades, specifically from CAT5e to CAT6 cabling, to sustainably support higher throughput without congestion or data loss (Cisco, 2019). The decision hinges on factors like future growth projections, current operational load, and the cost-benefit analysis of network upgrades.

Modeling Throughput with Rational Functions and Visualization

The throughput speed R(t) can often be modeled with rational functions that capture traffic dynamics over time. Using a representative function such as R(t) = a / (b + t), where 'a' and 'b' are constants derived from empirical data, allows visualization of throughput decay or growth patterns. Generating the graph using tools like Excel involves plotting R(t) against time to understand peak and sustained performance levels.

For example, a graph shows high throughput at initial burst times (t approaching zero), indicative of peak throughput conditions, then gradually stabilizes to a lower sustained level as time progresses, mimicking typical network behavior under load (Liu et al., 2016).

Peak and Sustained Throughput Evaluation

Peak throughput (PT) signifies the maximum instantaneous data rate achievable during burst periods. Analyzing the function R(t), algebraic techniques such as evaluating the limit as t approaches zero enable estimation of PT. If PT exceeds the current bandwidth of 1 Gbps, the network risks congestion during peak times, warranting bandwidth enhancements.

Maximum sustained throughput (ST) reflects the long-term average data transfer capacity as time tends to infinity. Calculating the limit of R(t) as t approaches infinity provides the stable throughput achievable under continuous operation. If ST is below or exceeds current bandwidth, it informs whether upgrading to support sustained high data rates is necessary.

Concluding Recommendations

Considering all analyzed metrics—current throughput calculations, peak rates, and sustained throughput—if the maximum or peak values significantly surpass the existing 1 Gbps threshold, an infrastructural upgrade to CAT6 cables and possibly higher bandwidth support should be pursued. Such upgrades ensure the school’s network can efficiently handle bursty traffic, future growth, and continuous high data demands, preventing bottlenecks and maintaining optimal performance.
