Internet Bandwidth Allocator
Optimize bandwidth distribution for multiple devices based on total bandwidth and device priorities.
Formulas Used
Bandwidth is allocated based on the priority weights of each device, ensuring higher-priority devices receive more bandwidth.
- Total Weight:
\[ W_{\text{total}} = \sum_{i=1}^{n} w_i \]
Where:
- \( W_{\text{total}} \): Sum of priority weights
- \( w_i \): Priority weight of device \( i \)
- \( n \): Number of devices
- Bandwidth per Device:
\[ B_i = B_{\text{total}} \cdot \frac{w_i}{W_{\text{total}}} \]
Where:
- \( B_i \): Bandwidth allocated to device \( i \) (Mbps)
- \( B_{\text{total}} \): Total available bandwidth (Mbps)
- Allocation Level:
Based on \( B_i \):
- Low: \( B_i \leq 10 \, \text{Mbps} \)
- Moderate: \( 10 < B_i \leq 50 \, \text{Mbps} \)
- High: \( B_i > 50 \, \text{Mbps} \)
Example Calculations
Example 1: Equal Priorities
Inputs: Total Bandwidth = 100 Mbps, Devices = 3, Priorities = [1, 1, 1]
Calculations:
- Total Weight: \[ 1 + 1 + 1 = 3 \]
- Bandwidth per Device: \[ 100 \cdot \frac{1}{3} \approx 33.33 \, \text{Mbps} \]
- Allocation Level: Moderate (10–50 Mbps)
Result: Device 1: 33.3 Mbps (Moderate), Device 2: 33.3 Mbps (Moderate), Device 3: 33.3 Mbps (Moderate)
Example 2: Varied Priorities
Inputs: Total Bandwidth = 200 Mbps, Devices = 2, Priorities = [3, 1]
Calculations:
- Total Weight: \[ 3 + 1 = 4 \]
- Device 1: \[ 200 \cdot \frac{3}{4} = 150 \, \text{Mbps} \]
- Device 2: \[ 200 \cdot \frac{1}{4} = 50 \, \text{Mbps} \]
- Allocation Levels: Device 1: High (>50 Mbps), Device 2: Moderate (10–50 Mbps)
Result: Device 1: 150.0 Mbps (High), Device 2: 50.0 Mbps (Moderate)
Example 3: Multiple Devices
Inputs: Total Bandwidth = 500 Mbps, Devices = 5, Priorities = [2, 2, 1, 1, 1]
Calculations:
- Total Weight: \[ 2 + 2 + 1 + 1 + 1 = 7 \]
- Device 1: \[ 500 \cdot \frac{2}{7} \approx 142.86 \, \text{Mbps} \]
- Device 2: \[ 500 \cdot \frac{2}{7} \approx 142.86 \, \text{Mbps} \]
- Device 3: \[ 500 \cdot \frac{1}{7} \approx 71.43 \, \text{Mbps} \]
- Device 4: \[ 500 \cdot \frac{1}{7} \approx 71.43 \, \text{Mbps} \]
- Device 5: \[ 500 \cdot \frac{1}{7} \approx 71.43 \, \text{Mbps} \]
- Allocation Levels: Devices 1–2: High (>50 Mbps), Devices 3–5: High (>50 Mbps)
Result: Device 1: 142.9 Mbps (High), Device 2: 142.9 Mbps (High), Device 3: 71.4 Mbps (High), Device 4: 71.4 Mbps (High), Device 5: 71.4 Mbps (High)
How to Use the Calculator
Follow these steps to optimize bandwidth allocation:
- Enter Total Bandwidth: Input the total available bandwidth in Mbps (0.1–1000, e.g., 100). Use the decimal point button (.) for precision.
- Enter Number of Devices: Input the number of devices (1–20, e.g., 3). This generates priority input fields for each device.
- Enter Priorities: For each device (e.g., Device 1, Device 2, etc.), input a priority weight (0.1–10, e.g., 1). Higher values mean more bandwidth. Use the decimal point button for precision.
- Calculate: Click “Calculate Bandwidth Allocation” to see the result.
- Interpret Result: The result shows the bandwidth per device in Mbps with an allocation level (Low: ≤10, Moderate: 10–50, High: >50). If you see “Please fill in all fields,” ensure all inputs are valid.
- Share or Embed: Use the share buttons to post results on social media, copy the result, or get an embed code.
Note: This is a simplified model assuming static priorities and no network overhead. Real-world allocation may depend on dynamic traffic, QoS settings, and router capabilities.
