As a packet sampling technology, sFlow samples IP packets moving from a source to a destination through a particular port. Sampled flow, commonly known as sFlow, is the standard technology for packet export in Layer 2 of the Open Systems Interconnection model.

Analyze and classify real-time network traffic.

It allows packets in the input stream to be sampled when enabled on an interface. J-Flow works by monitoring each packet that flows inside a network. The data includes all network activities, such as conversations inside enabled ports, and also identifies top talkers. Juniper Networks developed the data flow sampling technique known as J-Flow, which the SRX Series devices support.

Analyze instances of poor network performance.

NetFlow versions 5 and 9 are most commonly used. NetFlow datagrams carry information like the source address, destination address, source port, destination port, and protocol values in the flow record. NetFlow is often used for flow data analytics. It tracks and records all traffic as it enters and exits an interface. NetFlow was created by Cisco and is the most commonly used flow technology. It also helps you weed out performance and security issues within the network by analyzing network device traffic (i.e., traffic through routers, switches, firewalls, and servers).īenefits of using network traffic monitoring: Monitoring network traffic provides improved visibility and invaluable insights that are highly beneficial to understanding your network's behavior. Network traffic monitoring is the process of analyzing the traffic that flows across a network by keeping track of its source its destination and the applications, ports, and protocols involved in the conversation.

Busy/heavy traffic: Traffic that consumes a high amount of bandwidth.

Non-real-time traffic: Traffic consumed by an application for day-to-day activities.

Real-time traffic: Traffic that is time-sensitive and requires high-quality data transmission.

During data transmission, traffic data from the source gets divided into individual packets and is reassembled at the destination later. The data transferred is comprised of packets, which are the fundamental units of network data transfers. Network traffic is the total data moving through a network from a source to a destination at a given point in time.
