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 load-balancing.
  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.
• Time-stamping
  Highly accurate packet time-stamping and clock synchronisation from external time references.
