Adaptive Interrupt Frequency
The adapter driver intelligently adjusts host interrupt frequency based on traffic conditions to increase overall application
throughput. When traffic is light, the adapter driver interrupts the host for each received packet, minimizing latency. When
traffic is heavy, the adapter issues one host interrupt for multiple, back-to-back incoming packets, preserving host CPU
cycles.
ASIC with Embedded RISC Processor
The core control for Broadcom NetXtreme II adapters resides in a tightly integrated, high-performance ASIC. The ASIC
includes a RISC processor. This functionality provides the flexibility to add new features to the card and adapts it to future
network requirements through software downloads. This functionality also enables the adapter drivers to exploit the built-in
host offload functions on the adapter as host operating systems are enhanced to take advantage of these functions.
Broadcom Advanced Control Suite
Broadcom Advanced Control Suite (BACS) is an integrated utility that provides useful information about each network adapter
that is installed in your system. The BACS utility also enables you to perform detailed tests, diagnostics, and analyses on
each adapter, as well as to modify property values and view traffic statistics for each adapter.

Network Link and Activity Indication
For copper-wire Ethernet connections, the state of the network link and activity is indicated by the LEDs on the RJ-45
connector, as described in
Table 1
. For fiber optic Ethernet connections and SFP+, the state of the network link and activity is
indicated by a single LED located adjacent to the port connector, as described in
Table 2
. Broadcom Advanced Control Suite
also provides information about the status of the network link and activity (see
Viewing Vital Signs
).
