Garland Technology Introduces new 40G BiDirectional Visibility Solution at Cisco Live Berlin

June 7, 2016

 

Buffalo, NY—Garland Technology, the leading network TAP Manufacturer, introduces new 40G-SR-BiDi passive fiber network TAPs for network data center visibility solutions at Cisco Live Berlin.CiscoLive.png

Garland Technology, a proud sponsor of the Cisco Live user conference in Berlin, Germany has recently expanded its fiber network TAP product line to include the new 40G-SR-BiDi that works with Cisco’s new BiDirectional optical technology.

Garland Technology joined the Solution Partner Program in early 2014 – a network of companies that offers market-ready solutions for Cisco users. This program lets design experts at Garland Technology help Cisco users gain complete visibility for their advanced network monitoring tools.

“As bandwidth demands grow in the areas of monitoring and securing network traffic, we needed to provide a reliable visibility solution for our partners.  Our 40G-SR BiDi TAPs have been tested and validated  to ensure that all the data - every bit, byte, and packet® - feeds the Cisco Solution.” said Chris Bihary, CEO/Co-Founder of Garland Technology. “We are committed to providing solutions for the complete enterprise network, from 1G access to 10G distribution and up to 40G and now 100G data center core.”

Details on the new 40G-SR BiDirectional TAP include:

40G-SR BiDirectional TAP to support Cisco’s BiDirectional Optical Technology.  Features of this new product line include:

  • Exclusive High Density solution with 21 TAPs.
  • New Prism based technology that reduces bit errors on OM3 +OM4 applications.
  • Scalable design with 1U rack mount kit that holds up to 4 modules, each module can have 1, 2, or 3 TAPs.
  • Garland will showcase this product at the upcoming Cisco Live Berlin Expo, February 15-19, 2016.

The new Cisco 40G BiDirectional technology (see network flow diagram above) uses 2 parallel multi-mode fiber strands to transmit the signal bidirectionally instead of unidirectional. This quadruples the speed and allows for cost effective network migration from 10G to 40G.

Network TAPs are considered the best practice by network professionals when 100% packet capture and traffic visibility is required. Companies that still rely on their traditional SPAN port will eventually experience lost packets from oversubscribed ports, thus making their network monitoring and analysis appliances ineffective.

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.
