Network traffic is the level of activity on a computer network, based on the volume of data packets, delivery time, and bottlenecks. Monitoring software and operations analysts can help manage traffic, and tools can send notifications when traffic reaches certain values. Without monitoring tools, user complaints are the only way to detect problems.
Network traffic is a term used to explain the level of activity on a computer network. When computers are linked together in a network, data is sent back and forth in data packets. Network traffic or activity is based on the volume of data packets in the system, delivery time, and an assessment of any bottlenecks in the system.
As computer systems became more ingrained in business operations, the number of computers on a network increased. Network engineers and other systems professionals devote their time and effort to ensuring that the network can handle both current and future traffic. Staff expectations have risen and it has become increasingly important to monitor network traffic and keep the operating system within an ideal performance range.
The vast majority of network switches and servers come with traffic monitoring software. This software is constantly running and keeps a record of all data packets, including origin, destination, delivery time and route taken. Another feature often included in this type of software is security protocols. A network sniffer is a computer program that accesses the network and reads data packets as they travel within the network. Software that monitors network traffic can be configured to identify this type of program and alert the appropriate people.
Another method of monitoring network traffic is to have an operations analyst responsible for day-to-day management of the network. This person may be responsible for monitoring traffic indicators, assessing any bottlenecks or problems, and resolving them. This is an additional overhead expense, but may be justified for very sensitive networks or peak periods, where the system needs to perform at optimal levels.
The basic tools that come with a network switch can be configured to send automatic emails or notifications when traffic reaches certain values or tolerances. This method is best used for a very small network, where the cost of specialized software to monitor network traffic is not justified. Upon receipt of the notification, the network staff member should have protocols in place that determine what the next course of action should be.
The tools used to monitor traffic are constantly changing and being refined to provide a greater level of detail and accuracy. It’s important to note that without these tools, the only way to know when there’s a problem with your network is by user complaints. This method is the least effective, as it does not provide insight into the core problem. It is also highly subjective, based on personal preferences and pressures.
