{{Short description|Networking Hardware Appliance}}

<ref name=":0" />A '''data monitoring switch''' is a networking hardware appliance that provides a pool of monitoring tools with access to traffic from a large number of network links. It provides a combination of functionality that may include aggregating monitoring traffic from multiple links, regenerating traffic to multiple tools, pre-filtering traffic to offload tools, and directing traffic according to one-to-one and many-to-many port mappings.<ref>{{Cite web|title=Arista EOS® Precision Data Analysis with DANZ|url=https://www.arista.com/en/solutions/precision-data-analysis-of-network-traffic|last=Sabeesh|date=2017-10-24|website=Arista Networks|language=en-gb|access-date=2020-05-23}}</ref>

== DiversificationAdvantages ==

'''Data Monitoring Switches''' or Network Packet Brokers are mainly diversified using '''Bandwidths''' and '''End-users'''

* Data monitoring switches facilitate centralizing network traffic monitoring in the [[Network operations center|NOC]].

=== Bandwidths ===

* By providing remote monitoring and control, they save the time and expense of traveling to remote locations to install monitoring tools.

* They make it easier to share tools among groups.

* 1 Gbps-40 Gbps

* With data rate conversion capabilities, they enable 1 Gigabit tool to support 10 Gigabit links, and 10 Gigabit tools to monitor traffic aggregated from multiple 1 Gigabit links.

* 41 Gbps-80 Gbps

* They prevent tool oversubscription by pre-filtering traffic.

* 81 Gbps-100 Gbps

* They can Taptap network links directly, instead of relying on switch [[SPAN port]]s for monitoring access.

* Above 100 Gbps

* Because of their high port densities compared to discreet Taps, they save rack space and power and can have a lower price per port.

* They are fully passive and unable to disrupt network traffic in the most commonly found circumstances. (Integrated Taps, if present have fail-to-wire on power failure.) This is compared to SPAN ports, where network traffic can be disrupted if the switch is not properly configured while setting up the SPAN port.<ref>[http://www.ebizq.net/topics/business_service_management/features/11496.html?page=1 Integrating Monitoring Access Into The Network Architecture]</ref>
