GenieATM is a Flow-based solution supporting all major flow exporting protocols, including Netflow, sFlow and Netstream. In order to provide MPLS analysis, it supports MPLS-aware Flows using v9 Flow export format. In addition, GenieATM supports BGP, SNMP and RADIUS protocols to collect routing, device and user identity information respectively.
IP flow is a technology embedded in network routers and switches to gain visibility into IP traffic traversing networks and detect DDoS attacks. A flow is a unidirectional set of packets exported by routers and switches, which carries granular and accurate information of the IP traffic entering the routers and switches. Flow technology enables IP traffic analysis and answers the questions of who, what, where, when and how much IP traffic is on the networks. By receiving flow packets exported from the existing routers and switches, flow-based solutions enable IP traffic analysis without probes.
Therefore, for a large-scaled network of telecom, ISP or large enterprise, a flow-based solution is much more scalable and cost-efficient to carry out the network-wide network traffic analysis and security protection.
