Network traffic
Network traffic refers to the flow of data over a network. In switched networks, a traffic flow is a sequence of packets moving from a source to a destination and may involve multiple hosts across networks. A traffic flow can comprise all packets in a data transfer and need not be 1-to-1.
There are various definitions that describe traffic as a set of packets in transit within a given time window.
Bandwidth
Bandwidth is the capacity for data transfer per second, i.e., the speed at which data can be transmitted. In hosting environments, this capacity is typically shared among users on the server.
Traffic vs bandwidth
The main difference is that traffic is the amount of data moved, while bandwidth is the capacity through which the data can travel. Bandwidth is generally described as port speed and is measured in bits per second.
For example, a port with a given bandwidth can carry traffic up to that capacity, and actual monthly usage may vary.
Network traffic
Network traffic is the amount of data transmitted through the network over a given period. On dedicated or virtual servers, traffic includes data transferred from the network interface and data downloaded by a website in a given period.
Bandwidth vs network traffic
The key distinction is that traffic is the flow of data, while bandwidth is the capacity. Bandwidth is the port speed measured in bits per second.
In practice, the relationship between these concepts depends on utilization and capacity planning.
Monitoring tools for network traffic
- Wireshark — a free tool for capturing and analyzing packets and providing precise details for network professionals.
- SolarWinds Network Performance Monitor — an advanced commercial tool for monitoring network performance and generating detailed reports.
- PRTG Network Monitor — a comprehensive monitoring platform with diverse sensors for measuring bandwidth, traffic, and device status.
- Nagios — an open-source tool for monitoring networks and systems with alert capabilities.
- ManageEngine OpManager — an integrated solution for managing and monitoring networks with customizable dashboards.
