Garland Technology Announces the Release of the PacketMAX™ Advanced Features and Advanced Aggregator at CiscoLive!

January 28, 2019

NEW YORK, Jan. 28, 2019 -- Garland Technology, a leading provider of network test access point (TAP) and packet broker solutions, today announced, ahead of CiscoLive! Barcelona 2019, the release of two new products from their PacketMAX™ purpose-built packet broker line, developed to increase efficiency and utilization of existing network infrastructure.

"Garland's focus is on providing the highest quality, best-in-class solutions for today's Network Visibility Fabrics. As networks continue to grow we saw the need to launch a high density TAP aggregation device," states Jerry Dillard, Chief Technical Officer, Garland Technology. "With the increased volume of traffic, our customers' tools are struggling to keep up, so we looked for a way to reduce the number of packets being processed. We solved this with our PacketMAX™ Advanced Features, which can reduce traffic by up to 50% by removing duplicates and giving our customers the option of stripping off the payload."

 

SUMMARY AND HIGHLIGHTS OF PRODUCTS:

PacketMAX™: 10G Advanced Features - is a hardware device that provides advanced features such as deep window deduplication, Network Time Protocol (NTP) time stamping, and configurable packet slicing for both inline and out-of-band applications. Deduplication and packet slicing can significantly reduce the processing overhead from security or monitoring tools.

PacketMAX™: 100G 64 Port Advanced Aggregator  - improves ROI by reducing the total cost of a network visibility fabric and increasing the efficiency of existing infrastructure. The 100G 64 port Advanced Aggregator provides high density TAP aggregation and speed conversion with up to 256 10G interfaces managed on a single platform.

The continuous release of new products reflect the ongoing momentum Garland Technology is delivering to its 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.
