Improve Tool Efficiency

Industrial Solutions

Challenge: How to ensure optimal tool performance?

Network monitoring and security tools need packet data to properly analyze the task at hand. Teams are typically tasked with getting more out of their existing tool investments, which becomes challenging with growing traffic volumes and legacy architecture.

• Network and security tools can themselves be oversubscribed.

• Traffic growth outpaces existing tool capacity leading to reduced throughput and effectiveness

To get the data to these tools, your options are spanning a port from your switch or utilizing a network TAP. At the same time, it is imperative to not negatively affect the performance of these tools or the connected network.

SPAN ports generally do not affect the performance of the switch, though this varies with different SPAN port features / vendors, but can have an impact on your data and the tools and they are feeding, including:

• Designed for low-throughput situations, SPAN will drop packets if heavily utilized or oversubscribed.

Can duplicate packets if multiple VLANs are used.

• Can change the timing of the frame interactions, altering response times.

• Will not pass corrupt packets or connection errors

Solution

Network TAPs guarantee tools complete packet data

Network TAPs are purpose-built to pass 100% full duplex traffic, passing errors, without dropping packets or impacting the performance of the network, enhancing the monitoring and security tools they feed.

Other than an advanced XtraTAP, basic network TAPs are “set it and forget it,” requiring little management or impact to the deployment. See Network TAPs, to learn more about how TAPs can improve your network access.

Using data filtering to improve tool efficiency

With the growth in network traffic, analyzing this data is not only time consuming but expensive, as it usually includes an extensive number of tools and network segments.

A more cost-effective technique, that can be used in specific scenarios, is to isolate data that needs to be inspected, like VOIP traffic only, or traffic that has a higher risk of being a security threat and focus on analyzing just that data. This unburdens current tools by reducing traffic load, increasing tool effectiveness and performance.

This approach can be accomplished at the TAP level, with Garland’s XtraTAP or with a PacketMAX packet broker that is aggregating many links at once.

• Set utilization alerts for each monitoring port

• Remotely manage alerts to avoid oversubscription

• Set up filtering rules on layers 2, 3 and 4

• Aggregating and load balancing traffic for optimal performance
