Buffalo, NY (PRWEB) July 17, 2013 -- Garland Technology announces its new hire, Dale Fennell, for the position of sales engineer to provide pre- and post-sales support to clients. He will play an essential role in helping clients set up Network TAPs and monitor networks that maintain 100% visibility with no network downtime.

Fennell has more than 20 years of experience in the computer industry as a specialist, network administrator, and network engineer. During his career, he’s assumed a wide range of responsibilities that included installing and providing support for routers, services, security tools, and other equipment at more than 35 national locations. “I hired Dale when I was an owner at Network Critical, so I know he has a great knowledge of Network TAPs, Aggregation, Filtering, and Bypass TAP technology,” said CEO and Co-owner Chris Bihary of Garland Technology. “I’m excited to have him back with my team. We will continue to expand our workforce in both our Buffalo and Texas offices.”

Market leader Garland Technology is known for its modular Bypass TAP systems, and also provides Network, Aggregation, Regeneration, and Filtering TAPs for enterprise networks, government, global networks, service providers, and other businesses.

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.
