NetVizion Network Management: FAQ
NetFlow, a network protocol system that collects active IP network traffic as it flows in or out of an interface. That traffic data is analyzed to create a picture of the flow and volume of the traffic. With NetFlow analyzing the data, a network administrator can determine things such as the traffic’s point of origin, destination and paths of traffic on the network, class of service, and the causes of congestion. Netflow is used for finding bandwidth hogs, hunting down network threats, isolating application slowness issues and even for usage based billing by some ISP’s.
Packets that have the SAME IP attributes are grouped into a FLOW. This Flow is made up of these 5 or sometimes 7, attributes, including the Destination Port of the traffic.
- IP source address
- IP destination address
- Source port
- Destination port
- Layer 3 protocol type
- Class of Service
- Router or switch interface

You shouldn’t have to jerry-rig a tool meant for a single corporate installation to somehow work for multiple networks. NetVizion is built for service providers managing multiple networks, which means one dashboard to control everything, simple installation across an unlimited number of sites, smooth workflows, and easy switching between clients.
Two-factor authentication can be applied globally across your service provider account, making it required for all users. Or, for granular control, set it individually per user.
