Full Duplex Aggregation

Monitoring full duplex network traffic from multiple sources is often a critical requirement for network monitoring applications. For example, in order to properly monitor redundant networks or a pair of load balanced links, network professionals might need to receive traffic simultaneously from two different network segments.

In some cases, two network links may be bound together and operate as one logical network in order to improve bandwidth. In such an implementation, packets are distributed across two different physical links. Often, traffic transmits on one segment and receives on another. This makes network analysis and monitoring especially challenging. If an analyzer or monitoring device is put on only one physical link, it will not see the entire conversation.

Also, while traditional taps might enable fullduplex 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 have the required hardware to aggregate traffic.

The SINGLEstream™ Dual Link Aggregation Tap has two (2) network taps. Each tap combines both directions of a full duplex data stream and allows connected monitoring devices, even those with only one NIC, to receive a copy of all the data collected from both taps in a single trace file.
 

Totally Passive and Power Fault Tolerant

Fiber taps are completely passive devices and are not a point of failure on the network. Even if power is lost to the tap, the network traffic will not be affected. While some copper Gigabit taps prevent the operation of redundant routing and failover systems because they keep both sides of the network invisible to the other, the passive nature of optical fiber also eliminates this possibility of network failure. If one side of the link fails for any reason, the device on the other side of the link will recognize this outage immediately, so routers and switches can engage redundant protocols and failover systems. Because both sides of the link are always open, the network will automatically re-establish the primary link as soon as both sides of the network and the endpoint devices become operational.
 

Regeneration

One-to-Many configurations replicate copies of identical network traffic to provide multiple tools monitoring access to the same links. In addition to eliminating contention for access to critical links, multiple tools can be connected to the same link for redundancy, testing, or advanced monitoring applications.
 

Reliable and Easy to Use

Unlike setting up operating systems and binding NICs, the SINGLEstream™ Link Aggregation Tap is simple to deploy, and every unit comes with dual redundant power supplies to ensure monitoring uptime.
