Formulas Used in Network Latency Impact Calculator

The calculator uses the following formulas for latency impact:

Transmission Time:

\\[ T_{\text{trans}} = \frac{S \cdot 8}{B} \\]

Latency Time:

\\[ T_{\text{lat}} = N \cdot \text{RTT} \cdot 10^{-3} \\]

Total Transfer Time:

\\[ T_{\text{total}} = T_{\text{trans}} + T_{\text{lat}} \\]

Performance Impact:

\\[ I_{\text{perf}} = \frac{T_{\text{total}} – T_{\text{trans}}}{T_{\text{trans}}} \cdot 100 \\]

Where:

\\( S \\): Data size (MB)
\\( B \\): Bandwidth (Mbps)
\\( \text{RTT} \\): Round-trip time (ms)
\\( N \\): Number of round trips
\\( T_{\text{trans}} \\): Transmission time (s)
\\( T_{\text{lat}} \\): Latency time (s)
\\( T_{\text{total}} \\): Total transfer time (s)
\\( I_{\text{perf}} \\): Performance impact (%)

Example Calculations

Example 1: Standard Case

Input: Data Size = 10 MB, Bandwidth = 100 Mbps, RTT = 50 ms, Round Trips = 2

\\[ T_{\text{trans}} = \frac{10 \cdot 8}{100} = 0.8 \, \text{s} = 800 \, \text{ms} \\] \\[ T_{\text{lat}} = 2 \cdot 50 \cdot 10^{-3} = 0.1 \, \text{s} = 100 \, \text{ms} \\] \\[ T_{\text{total}} = 800 + 100 = 900 \, \text{ms} \\] \\[ I_{\text{perf}} = \frac{900 – 800}{800} \cdot 100 = 12.5 \, \% \\]

Result: T_trans = 800 ms, T_lat = 100 ms, T_total = 900 ms, I_perf = 12.5%

Example 2: High Latency

Input: Data Size = 10 MB, Bandwidth = 100 Mbps, RTT = 200 ms, Round Trips = 2

\\[ T_{\text{trans}} = 800 \, \text{ms} \\] \\[ T_{\text{lat}} = 2 \cdot 200 \cdot 10^{-3} = 400 \, \text{ms} \\] \\[ T_{\text{total}} = 800 + 400 = 1200 \, \text{ms} \\] \\[ I_{\text{perf}} = \frac{1200 – 800}{800} \cdot 100 = 50 \, \% \\]

Result: T_trans = 800 ms, T_lat = 400 ms, T_total = 1200 ms, I_perf = 50%

Example 3: Large Data Size

Input: Data Size = 50 MB, Bandwidth = 100 Mbps, RTT = 50 ms, Round Trips = 2

\\[ T_{\text{trans}} = \frac{50 \cdot 8}{100} = 4000 \, \text{ms} \\] \\[ T_{\text{lat}} = 2 \cdot 50 \cdot 10^{-3} = 100 \, \text{ms} \\] \\[ T_{\text{total}} = 4000 + 100 = 4100 \, \text{ms} \\] \\[ I_{\text{perf}} = \frac{4100 – 4000}{4000} \cdot 100 = 2.5 \, \% \\]

Result: T_trans = 4000 ms, T_lat = 100 ms, T_total = 4100 ms, I_perf = 2.5%
