Amazingly Scalable Network Visibility with the NTO 7300

Over the past year I have had the pleasure of speaking to dozens of large enterprise and service provider customers who have been experiencing rapid increases in bandwidth, application complexity, overall scale, and the management challenges that come with them. While each network carries its own unique characteristics and challenges, through those conversations I learned that they are no longer just trying to get the “plumbing” to work, but are trying to ensure application viability, customer e...

Comparing the use of Taps and Span Ports

What is a Tap? Test Access Ports or Taps are primarily used to optimize ITs ability to easily and passively monitor a network link. They are normally placed between any two network devices, including switches, routers, and firewalls to provide network and security personnel a connection for monitoring devices. Protocol analyzers, RMON probes and intrusion detection and prevention systems can now be easily connected to and removed from the network when needed. By using a Tap, you also eliminate t...

Using xBalancer to Monitor Your 10 Gig Networks

Two big challenges with 10Gig monitoring are security gaps and the other is overall performance the existing security tools that cannot keep up with the overall throughput and the bandwidth of the network. As a result the 10 Gig links are growing rapidly and the backbones are getting huge. From an attack standpoint they're getting much more sophisticated and as a result the rules in the security devices are getting much more complex. A lot of the resources for being allocated now for content ins...

Leveraging a Visibility Architecture Really Can Make Your Life Easier!

Ixia recently announced its Visibility Architecture, an end-to-end approach to network, application, and security visibility. For some, the first questions asked will likely be “What is a Visibility Architecture?” and “Can it really help me?” The answer to both questions is a resounding yes! First of all, what do we even mean by visibility? Visibility is defined by Webster as the “capability of being readily noticed” or “the degree of clearness.” By network or application visibility, for example...

Addressing Monitoring, Access, and Control Challenges in a Virtualized Environment

Today, network traffic between Virtual Machines (VMs) is skyrocketing past predictions, while network administrators continue to lag in terms of visibility and control of that inter-VM communication. As this traffic soars to more than 50 percent of all traffic on the network, the security and compliance challenges raised by lack of visibility into the virtualized environment have become acute. The financial and legal consequences of this visibility deficit are severe and of long duration, with a...

TAPs Overview: The Start of Visibility

Change is coming to networks faster than ever before. While growth is a new constant in most networks, it is being compounded by new regulations, virtualization of workloads and services, changing security needs, and migration of applications between data centers and the cloud. Network and IT organizations are caught in a constant cycle of deploying new services, supporting new use cases, and managing growth – which results in networks that are always trying to get back to a reliable state befor...
