Garland Technology TAPs Industry Demand with New Regeneration Products

September 23, 2019

NEW YORK, Sept. 23, 2019   -- Garland Technology, a leading provider of network test access point (TAP) and packet broker solutions, today announced the release of the new RegenTAP: 1x5 and RegenTAP: Dual Breakout appliances. Network TAPs are hardware devices that create an exact full duplex copy of network traffic, without compromising network integrity. Regeneration TAPs provide multiple complete copies of this data to monitoring and security devices in your network.

"We started noticing some similar products in the marketplace have been discontinued and end-of-life (EoL) without viable replacements, and we strive to fill that demand," states Jerry Dillard, CTO/Co-Founder, Garland Technology. "Garland Technology is focused on continued development and innovation on network access products, where building a strong foundation of visibility is more critical than ever."

SUMMARY AND HIGHLIGHTS OF PRODUCT

The RegenTAP: 1x5 is a network TAP that provides up to five complete copies of data from a single link to monitoring or security devices in your network. It's typically used when you have multiple monitoring devices and need to guarantee every packet to them, a common requirement in government, financial, and enterprise accounts for packet capture, storage requirements and regulations.

The RegenTAP: Dual Breakout is a network TAP that also provides multiple complete copies of data to monitoring and security devices in your network. The Dual Breakout houses two TAPs in one appliance, while providing tap 'breakout' copies of data, this product also provides aggregation copies for additional applications.

A multifaceted device, the Dual Breakout can be used to TAP 10G Copper links or unique types of links, like direct connect cables, which can be difficult to monitor and get visibility into the network. These are very effective in finance, government, telecom, or lawful intercept cases that need all the packets but do not require the sophistication of filtering and aggregation.

The continuous release of new products reflects the ongoing momentum Garland Technology is delivering to their customers worldwide.

Heartbeats Packets Inside the Bypass TAP

If the inline security tool goes off-line, the TAP will bypass the tool and automatically keep the link flowing. The Bypass TAP does this by sending heartbeat packets to the inline security tool. As long as the inline security tool is on-line, the heartbeat packets will be returned to the TAP, and the link traffic will continue to flow through the inline security tool.

If the heartbeat packets are not returned to the TAP (indicating that the inline security tool has gone off-line), the TAP will automatically 'bypass' the inline security tool and keep the link traffic flowing. The TAP also removes the heartbeat packets before sending the network traffic back onto the critical link.

While the TAP is in bypass mode, it continues to send heartbeat packets out to the inline security tool so that once the tool is back on-line, it will begin returning the heartbeat packets back to the TAP indicating that the tool is ready to go back to work. The TAP will then direct the network traffic back through the inline security tool along with the heartbeat packets placing the tool back inline.

Some of you may have noticed a flaw in the logic behind this solution!  You say, “What if the TAP should fail because it is also in-line? Then the link will also fail!” The TAP would now be considered a point of failure. That is a good catch – but in our blog on Bypass vs. Failsafe, I explained that if a TAP were to fail or lose power, it must provide failsafe protection to the link it is attached to. So our network TAP will go into Failsafe mode keeping the link flowing.

Glossary

  1. Single point of failure: a risk to an IT network if one part of the system brings down a larger part of the entire system.

  2. Heartbeat packet: a soft detection technology that monitors the health of inline appliances. Read the heartbeat packet blog here.

  3. Critical link: the connection between two or more network devices or appliances that if the connection fails then the network is disrupted.
