DAG Card Features & Functions
In addition to full line rate packet capture, DAG® cards also provide a range of additional hardware-based functions, delivering further significant performance benefits over a software-only solution. These include:
- Load balancing
Evenly load-balance up to 10 Gigabits of network traffic to a maximum of 32 memory buffers using intelligent hardware.
Traffic from a single interface may be evenly distributed across multiple memory buffers, while maintaining flow and session continuity. Each application can access its own receive stream in a separate memory buffer. - Packet filtering and classification
Hardware-based classification and filtering provides the ability to interrogate packet protocol headers and compare them with preset rules in hardware. This allows packets to be filtered (accepted or dropped) or classified as they arrive at the DAG card interface. Providing pre-classified network packets to consuming applications, dramatically speeding up their performance. - Traffic replication
Packets may be cloned to multiple memory buffer locations to provide network traffic replication. - Timestamping
Highly accurate packet timestamping and clock synchronisation from external time references.

DAG Powered Systems
Born out of the need to supply our DAG®card customers with server hardware that was genuinely capable of running high-speed packet analysis applications, we developed our range of Endace Systems.
By integrating our industry-leading DAG cards into a highly optimised server solution which has been specifically designed to enable maximum I/O bandwidth between the DAG cards, CPU, memory and storage we have been able to create our unique Endace Systems.
