NetFlow is a feature that was introduced on Cisco routers that provides the ability to collect IP network traffic as it enters or exits an interface. By analyzing the data provided by NetFlow, a network administrator can determine things such as the source and destination of traffic, class of service, and the causes of congestion. There are numerous key metrics when it comes to Netflow Monitoring: 1-Netflow Top Talkers The flows that are generating the heaviest system traffic are known as the "t...

“Who Makes the Rules?” The Hidden Risks of Defining Visibility Policies

Imagine what would happen if the governor of one state got to change all the laws for the whole country for a day, without the other states or territories ever knowing about it. And then the next day, another governor gets to do the same. And then another. Such foreseeable chaos is precisely what happens when multiple IT or security administrators define traffic filtering policies without some overarching intelligence keeping tabs on who’s doing what. Each user acts from their own unique perspec...

Advanced Packet Filtering with Ixia’s Advanced Filtering Modules (AFM)

An important factor in improving network visibility is the ability to pass the correct data to monitoring tools. Otherwise, it becomes very expensive and aggravating for most enterprises to sift through the enormous amounts of data packets being transmitted (now and in the near future). Bandwidth requirements are projected to continue increasing for the foreseeable future – so you may want to prepare now. As your bandwidth needs increase, complexity increases due to more equipment being added to...

How Not to Rollout New Ideas, or How I Learned to Love Testing

I was recently reading an article in TechCrunch titled “The Problem With The Internet Of Things,” where the author lamented how bad design or rollout of good ideas can kill promising markets. In his example, he discussed how turning on the lights in a room, through the Internet of Things (IoT), became a five step process rather than the simple one step process we currently use (the light switch). This illustrates the problem between the grand idea, and the practicality of the market: it’s awesom...

Failure to adequately monitor each of these and their interactions, means that you could be flying blind – susceptible to degraded service levels.

State of Networks: Faster, but Under Attack

Two recent studies that look at the state of mobile and fixed networks show that while networks are getting ever faster, security is a paramount concern that is taking up more time and resources. Akamai recently released its fourth quarter 2014 State of the Internet report. Among the findings: In terms of network security, high tech and public sector targets saw increased numbers of attacks from 2013 to 2014, while enterprise targets had fewer attacks over the course of the year – except Q4, whe...

See How Ixia’s NTO 7300 Vastly Outperforms the Closest Competitor in 100GbE Visibility, Scalability, Capacity, and Cost-Efficiency

Visibility Is an Urgent Challenge Lack of visibility is behind the worst of IT headaches, leaving the network open to malicious intrusions, as well as compliance, availability, and performance problems. Today’s soaring traffic volumes are bringing greater complexity, proliferating apps and devices, and rising virtual traffic—in fact, “east-west” traffic between virtual machines now makes up half of all traffic on the network. Virtual traffic is the culprit that spawns unmonitored "blind spots," ...
