Garland Technology is a Sponsor at Palo Alto Networks User Conference

February 18, 2015

Ignite2015Buffalo, NY (PRNewswire) February 18, 2015 -- Garland Technology, a leading manufacturer of network visibility and data access hardware, is a sponsor of the Palo Alto Networks Ignite 2015 user conference. The show focuses on Palo Alto Networks solutions and trends in tech security with a focus on the end user. Special guests include Jamie Hyneman and Adam Savage from "Mythbusters" as well as the CEO and CTO of Palo Alto Networks.

"Ignite is promising to be very big this year," says Garland Technology CEO Chris Bihary. "Between the growing need for cyber security and the emergence of the Palo Alto Networks user community FUEL, I can't imagine a security professional who would not want to be there."

Breakout sessions are broken up into topic-based tracks, including "Advanced Threat Protection Strategies," "Data Center Security Architectures" and "Industry Innovations". Garland Technology will showcase network visibility technologies and network design services that complement the security tools offered by vendors like Palo Alto Networks. Focusing on connecting technology at the edge of the network, as well as guaranteeing 100% uptime and all data, will be a cornerstone of the Garland Technology booth.

Ignite 2015 is taking place at The Cosmopolitan Hotel of Las Vegas in Las Vegas, NV from March 30 – April 1. Registration details can be found here: https://www.paloaltonetworks.com/content/campaigns/ignite/2015/index.html

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.
