Link-Inline™ Software 3.0

Napatech Link-Inline™ Software ensures that all programmed flows are processed on the SmartNIC for maximizing overall system performance.

Lookup table capacity

The lookup table for flows and policies is stored in onboard SDRAM. 140 million records can be stored on NT200A02 (64-byte records, using 12-Gbyte onboard SDRAM).
Note: Frames from the receive pipeline are not stored in onboard SDRAM before transferred to the host memory or transmitted on the TX port.

Lookup rates

Flow/policy lookup rates are as follows.
  • 130 million lookups per second for stateless lookups (flow lookups).
  • 85 million lookups per second for stateful lookups (policy lookups).
Flow lookups are stateless as flow records are not updated whereas policy lookups are stateful as updating the leaky-bucket state and usage counters for metering are carried out.
Note: The given lookup rates are calculated assuming no cache hits. The lookup rates would be higher in practice if recently used flows and policies are cached in the SmartNIC.

Other capabilities

  • Fast path forward latency is below 10 µs.
