Network traffic refers to the flow of data and information sent and received on a computer network. It is the backbone of any network and is essential for communication and connectivity. Network traffic can be classified into two types – Internal & External traffic.
Internal Traffic
Internal traffic happens within a network. Data and information are sent and received between devices that are connected to the same network. This type of traffic can be further classified into local and remote traffic. Local traffic happens between devices that are directly connected to each other, while remote traffic gets rerouted through other network devices like routers and switches.
External Traffic
External traffic happens when data and information are sent and received between devices located outside of the network. For example, when you're browsing the internet or sending an email, you're generating external traffic. This kind of traffic is essential to keep a network connected to the internet and other networks.
Managing Network Traffic
Managing network traffic is essential to keep network performance running smoothly. Network administrators need to ensure that there's no congestion in the network and that all devices can communicate effectively. This can be done by implementing various network management techniques such as Quality of Service (QoS) and traffic shaping. Additionally, network administrators can use network traffic monitoring tools that allow them to monitor network traffic and identify any issues in real time.
Conclusion
In conclusion, network traffic is an essential part of any computer network. Without it, devices would not be able to communicate with each other, and networks wouldn't be connected to the internet. Managing network traffic is crucial to ensure that networks run smoothly and devices can communicate effectively. Network administrators need to pay close attention to all types of network traffic and implement measures that allow them to manage the flow of data and information effectively.
