Description:
Monitoring network traffic from two different sources is an important and frequent requirement in network analysis, commonly referred to as data “aggregation.” For example, in order to properly troubleshoot most network problems, network professionals need to receive traffic from both sides of a full duplex conversation.
While traditional taps might enable full-duplex monitoring of all traffic on a network link, they transmit the data to the connected monitoring device in two separate half-duplex streams (one for Tx and one for Rx). Not only does this require the monitoring device to have two network interface cards, it also requires that the device be capable of combining and processing both streams of data in order to monitor both sides of the conversation. Not all monitoring systems, including the most popular software solutions, have the required hardware to aggregate traffic.
The SINGLEstream Link Aggregation Tap combines both directions of a full duplex data stream and allows any connected monitoring device, including those with only one NIC, to receive a copy of all the data – in a single trace file.
