Security device and network flow analyzing device based on network bypass deployment increase gradually, as the network security develops rapidly
and enterprise security gets more attention. Therefore, if two or more bypass
audio monitors are deployed, it may not only increase the performance overhead
of core switch, but also fail to meet the demands for deployment of various
security devices.
As shown in the picture above, data flow from the core switch must be
monitored, as the intrusion detection system, network behavior audit system,
flow analyzer and other devices are all bypass deployed devices. NetTAP flow
replicator can flexibly use flow replication technology to replicate the
mirrored data flow from the core switch to multiple ports.
Wireless communication network has entered a refined network analyzing
era; therefore, it is necessary for the operator to analyze and process the
network signal to improve their business operation efficiency. Signal
monitoring platform is an important support system for the operation and
maintenance of the communication network and can identify various network and
business indicators without affecting the normal operation of the network. To
achieve signal monitoring, the communication data among various network elements
(MSC/MGW/GGSN/SGS) of the core network shall be completely replicated,
aggregated and distributed, so as to help the signal monitoring solution
restore and analyze the protocol of the signal data.
