Item Definition
ARP Address Resolution Protocol
BACS Broadcom Advanced Control Suite
BASP Broadcom Advanced Server Program (intermediate driver)
DNS domain name service
G-ARP Gratuitous Address Resolution Protocol
Generic Trunking (FEC/GEC)/802.3ad-Draft Static Switch-dependent load balancing and failover type of team
in which the intermediate driver manages outgoing traffic
and the switch manages incoming traffic.
HSRP Hot Standby Router Protocol
ICMP Internet Control Message Protocol
IGMP Internet Group Management Protocol
IP Internet Protocol
IPv6 Version 6 of the IP Protocol
iSCSI Internet Small Computer Systems Interface
L2 Layer 2. Used to describe network traffic that is not
offloaded, and where hardware only performs Layer 2
operations on the traffic. Layer 3 (IP) and Layer 4 (TCP)
protocols are processed in software.
L4 Layer 4. Used to describe network traffic that is heavily
offloaded to the hardware, where much of the Layer 3 (IP)
and Layer 4 (TCP) processing is done in the hardware to
improve performance.
LACP Link Aggregation Control Protocol
Link Aggregation (802.3ad) Switch-dependent load balancing and failover type of team
with LACP in which the intermediate driver manages
outgoing traffic and the switch manages incoming traffic.
LOM LAN on Motherboard
MAC media access control
NDIS Network Driver Interface Specification
NLB Network Load Balancing (Microsoft)
PXE Preboot Execution Environment
RAID redundant array of inexpensive disks
Smart Load Balancing™ and Failover Switch-independent failover type of team in which the
primary team member handles all incoming and outgoing
traffic while the standby team member is idle until a failover
event (for example, loss of link occurs). The intermediate
driver (BASP) manages incoming/outgoing traffic.
Smart Load Balancing (SLB) Switch-independent load balancing and failover type of
team, in which the intermediate driver manages outgoing/
incoming traffic.
TCP Transmission Control Protocol
TOE TCP Offload Engine. This is the hardware that is capable of
handling stateful fastpath offloading of TCP and IP
processing.
UDP User Datagram Protocol
