Traffic Segmentation

Captured packets are trafficked to individual instances of the DNCA based upon the specified Desired Traffic for each instance and the global Ignored Traffic settings.

DNCA examines every network packet and determines how to traffic it based upon the filter rules. With the help of filter rules, you can specify where you want the required traffic to go, help balancing the load between multiple DNCA instances, and define the types of traffic that DNCA can ignore.

Note: The DNCA automatically configures its listen filters to allow 802.1q VLAN packets in for capture. See VLAN Filters.

To remove all filters from all instances, select Remove Filters in the General Functions section.

Either of the following two methods can be configured in the Interface tab to segment traffic loads to multiple instances of the DNCA:

Web Server Host IP/Port Addresses Filtering: The typical and preferred method for segmenting traffic by DNCA instance is to filter on web server host IP/Port addresses. See Web Server Host IP/Port Addresses Filtering.
TCP Client Port Segmentation Filtering: The alternate method, TCP client port segmentation, is used when the capture traffic is presented as a single virtual web IP address (VIP). See TCP Client Port Segmentation Filtering.
