Overview

Purpose: The Bandwidth Management dashboard provides a detailed view of network bandwidth usage, enabling users to monitor traffic by interface and external sources (ASNs). This dashboard helps identify which interfaces and Autonomous Systems (ASNs) are generating the most traffic, which can aid in recognizing potential network issues or bottlenecks.

Components: The dashboard is composed of four primary visualizations:

• Traffic by Interface (Top Left)
• Bandwidth of Top Interfaces (Top Right)
• Traffic by Autonomous Systems (Bottom Left)
• Top Autonomous Systems (Bottom Right)

Getting Here

1. From the main menu, navigate to Dashboards > All.
2. In the horizontal navigation at the top of the page, click on the System tab.
3. Select Bandwidth Management.

Main Points

Usage Scenarios: This dashboard is particularly useful for network administrators who need to manage network load, troubleshoot traffic issues, and monitor high-usage sources in real time.

Best Practices: Regularly check the dashboard during peak traffic times to identify any unusual spikes or trends. Use the metric selection and time range tools to isolate and analyze specific traffic data more thoroughly.

Charts

Traffic by Interface (Top Left)

Description: This area chart shows the traffic volume across the top interfaces over a selected time range.

Key Elements:

• X-axis: Time in hours and minutes.
• Y-axis: Bitrate in Gbps (Gigabits per second).
• Color-Coded Lines: Each line represents a specific interface, identified by color.

Usage: Track bandwidth usage on each interface over time to detect surges or irregularities that may indicate potential network problems.

Bandwidth of Top Interfaces (Top Right)

Description: This bar chart displays the bandwidth usage for the top interfaces.

Key Elements:

• X-axis: Bitrate in Gbps.
• Y-axis: Top interfaces, ranked by bandwidth usage.
• Color-Coded Bars: Each bar represents an interface, with the bar length indicating the amount of traffic.

Usage: Provides a quick way to identify which interfaces are consuming the most bandwidth, allowing for targeted management of network load.

Traffic by Autonomous Systems (Bottom Left)

Description: This area chart illustrates the traffic attributed to external Autonomous Systems (ASNs).

Key Elements:

• X-axis: Time in hours and minutes.
• Y-axis: Bitrate in Gbps.
• Color-Coded Sections: Each colored area represents traffic from a different ASN.

Usage: Enables tracking of traffic originating from external ASNs, helping administrators assess external network impacts on bandwidth.

Top Autonomous Systems (Bottom Right)

Description: This bar chart highlights the top Autonomous Systems contributing to the network's overall traffic.

Key Elements:

• X-axis: Bitrate in Mbps and Gbps.
• Y-axis: Top ASNs, organized by traffic volume.
• Color-Coded Bars: Each bar represents an ASN, with length indicating its contribution to the total traffic.

Usage: Quickly identify high-traffic ASNs, which assists in planning and securing network resources.

Interpreting the Data

Traffic Surges: Noticeable spikes in the "Traffic by Interface" or "Traffic by Autonomous Systems" charts may indicate periods of high usage or network strain.

High-Usage Interfaces/ASNs: The "Bandwidth of Top Interfaces" and "Top Autonomous Systems" charts allow administrators to pinpoint interfaces and ASNs with high traffic volumes, useful for optimizing performance and troubleshooting.

Additional Features

Metric Selection: Users can select different metrics, like bitrate, to customize their view and focus on relevant data.

Time Range: Adjusting the time range allows for a focused analysis of traffic patterns over specific periods.

Interactive Elements: The SYNC HOVER feature lets users hover over data points, synchronizing related visualizations for integrated data analysis.
