NEW YORK, Oct. 25, 2018 /PRNewswire/ -- Garland Technology, a leading provider of network and test access solutions, today announced a release of two new products, a 40G Bypass Network TAP, that addresses evolving security threats, and a 1G Advanced Aggregator, which increases efficiency and utilization of existing infrastructure.
"With Garland's continued focus on providing the highest quality and best-of-class functionality in today's network test access products, we are continually striving to meet industry demands," states, Jerry Dillard, Chief Technical Officer, Garland Technology. "It is important to address the challenges network and security teams face by providing customers with complete network visibility."
SUMMARY AND HIGHLIGHTS OF PRODUCTS:
1G Advanced Aggregator System: Garland Technology's 1G Advanced Aggregators are devices designed to increase the efficiency and port utilization of network packet brokers through aggregation, filtering and tunneling. Aggregators improve ROI by reducing the total cost of a network visibility fabric and increasing the efficiency of existing infrastructure.
Bypass Modular Network TAP 40G System: Garland Technology's new 40G modular bypass TAP is for use with inline security tools. Network bandwidth requirements are continuously increasing, so this device is designed to support any network with a 10G or 40G infrastructure and tools. Bypass technology, developed by Garland Technology's CTO Jerry Dillard, increases network uptime by preventing inline devices from disrupting the network by "bypassing" that device, in the event it fails or needs to be updated.
To support the new products in their portfolio, Garland Technology has hired five new members to its sales teams in North America to include:
The continuous release of new products and additions to the team reflects the ongoing momentum Garland Technology is delivering to is customers worldwide.

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.
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.
Heartbeat packet: a soft detection technology that monitors the health of inline appliances. Read the heartbeat packet blog here.
Critical link: the connection between two or more network devices or appliances that if the connection fails then the network is disrupted.
