Load Balancing with MAC or IP Address
The Windows 2000 Teaming Utility lets you load balance IP Packets among
the teamed NICs installed in a server. The primary NIC in the team receives
all incoming packets. The choice is available to load balance with the source
MAC address (the address transmitted from the workstation) or the source IP
address.
Using the last four bits of either source address, the teaming driver algorithm
then assigns this source address to the port of one of the NICs in the team.
This port is then used to transmit all packets destined for that source address.
This configuration the transmission of packets from the server by sharing the
packets among all the NICs in the team. If there are four NICs in the team, the
packets are received by the primary NIC on the team. The packets are
retransmitted through one of the four ports.
Detailed information about these four load-balancing teaming options can be
found in the Compaq Network Teaming and Configuration Help.
