Ixia Video: What is a Virtual Tap?
Author: David Avery
Ixia has just posted a quick tutorial on “virtual taps.” This tutorial will answer the following questions:
- What is a virtual tap?
- How and where do you deploy a virtual tap in the network?
- What are the benefits of using a virtual tap?
Virtualization is one of the most influential trends in networking, both lowering hardware costs and enabling efficient use of network resources. Today, more than 80 percent of data center traffic travels between servers, making total visibility critical to network security and performance. Unfortunately, virtualization presents a major challenge in the form of blind spots that can lay a network open to intrusion, error, and compliance issues, as well as putting SLAs at risk.
Traffic between virtual servers residing on the same hypervisor (Inter-VM or “east-west” traffic) is managed by virtual switching internal to the hypervisor. This traffic is switched locally and never gets out to monitoring tools, creating a “blind spot” or “black hole.”
The answer to these challenges is a highly scalable visibility architecture that enables the elimination of current blind spots, while providing resilience and control without added complexity.
A virtual tap is a key part of a visibility architecture. Watch this video to find out how a virtual tap can improve your network security and performance.
