Traffic Monitoring Application
In traditional network applications, TAP devices are used to sample egress traffic flow. With the expansion of network scale, there is growing requirement in deeper performance monitoring. The high performance TAP devices can be used for such application.
Figure 1: Traffic Monitoring Application
As shown in figure above, user can enable the timestamp and source port label function of TAP devices, the server cluster can access the exact packet process time in each layer via source port and timestamp message carried by the packets. From port1, port2, port3, user can distinguish the devices that the streams come from. Through T1, T2 and T3, packets forward latency of each device can be calculated, according to that, user can find out the bottleneck during packet forwarding for the further optimization of network.
DPI Applications
Generally, TAP devices can be used to assist DPI (Deep Packet Inspection) in networks. TAP is applied to forward flows to intranet and sends a mirrored copy of the packet flow to DPI device at the same time. The DPI device is for traffic analysis, once a virus on website or illegal information has been monitored, the flows will be blocked by a five elements table sent from management channel between DPI and TAP.
