Overview of network traffic monitoring
What is network traffic?
Network traffic is the amount of data transferred through a network from a source to a destination at a specific time. This data is transmitted in the form of packets, which are the basic building blocks of network data transfers, and are reassembled at the destination.
What is network traffic monitoring?
Network traffic monitoring is the process of analyzing the flow of data across a network to gain insights into network behavior, analyze traffic patterns, and identify potential issues. It involves tracking the source, destination, and other metrics of network traffic and is usually achieved through specialized software tools that collect and analyze network traffic data in real time.
Benefits of network traffic monitoring:
- Analyze bandwidth issues
- Identify top talkers
- Improve user experience
What is a network traffic monitor?
A network traffic monitor in Site24x7 is any network device, such as a router or switch, for whichyou can observe and analyze traffic flows within your network. This enables you to get immediate insight into the use of network bandwidth, traffic patterns, and protocols being utilized. Site24x7 also displays the relevant measurements in an easy-to-use dashboard.
By analyzing traffic data, you can:
- Identify potential issues like bandwidth hogs within the network.
- Spot applications and device conversations that use high amounts of traffic.
- Plan for bandwidth allocation based on usage patterns.
What is NetFlow?
NetFlow by Cisco is the most commonly used flow technology. It tracks and records all traffic as it enters and exits an interface. NetFlow is often used for flow data analytics. NetFlow datagrams carry information like the source address, destination address, source port, destination port, and protocol values in the flow record. NetFlow versions 5 and 9 are most commonly used.
With NetFlow traffic analysis, you can:
- Identify bottlenecks in the network.
- Analyze instances of poor network performance.
What is J-Flow?
Juniper Networks developed the data flow sampling technique known as J-Flow, which is supported by SRX Series Devices. The sampled data includes all network activities, such as conversations inside enabled ports, and helps identify top talkers. J-Flow monitors each packet as it flows through a network. It allows packets in the input stream to be sampled when enabled on an interface.
With J-Flow traffic analysis, you can:
- Analyze and classify real-time network traffic.
- Assess network usage parameters.
What is sFlow?
Sampled flow, commonly known as sFlow, is the standard technology for packet export in Layer 2 of the Open Systems Interconnection model. As a packet sampling technology, sFlow samples IP packets moving from a source to a destination through a particular port. It provides the means of exporting truncated packets together with the interface counters. sFlow uses sampling to achieve scalability and is used for high-speed networks.
sFlow has two types of sampling:
- Packets or application layer operations (random sampling).
- Counters (time-based sampling).
How does the Site24x7 network traffic monitor work?
Site24x7 uses the On-Premise Poller to monitor network traffic. Once you install the On-Premise Poller (the NetFlow collector) and configure your devices to export flows to it, the On-Premise Poller starts receiving the flows. Then, it processes raw data and presents it intuitively in a custom dashboard or graphical reports.
Can I see what others are doing on my network?
Yes. Using NetFlow monitoring, you can view your network's IP and application traffic stats, which help you observe which particular IP and application has generated or consumed the most traffic.
How do I control network traffic?
You can control network traffic by configuring threshold limits for all the critical metrics, like incoming and outgoing traffic and bandwidth utilization. With these thresholds in place, you will receive alerts whenever the traffic or bandwidth breaches your configured values. Based on these alerts, you can identify the particular applications or ports that are responsible and block them.
What are the types of network traffic?
There are different types of network traffic such as data, video, voice, and control traffic. Each type has specific requirements, including bandwidth and prioritization.
Types of network traffic:
- Real-time traffic: Time-sensitive traffic that requires high-quality data transmission.
- Non-real-time traffic: Traffic that is consumed by an application for daily activities.
- Busy or heavy traffic: Traffic that utilizes a significant amount of bandwidth.
What are the best practices for monitoring network traffic?
Here are some suggestions for effectively monitoring network traffic usage and resolving any issues:
- Monitor your devices and interfaces
- Create a plan for determining your network's traffic requirements
- Measure traffic to gain insights into resource allocation
- Enhance efficiency by using Quality of Service (QoS)
- Choose the appropriate tool that can effectively monitor the traffic of your network, like Site24x7
