2 - 2-bit port based balancing: add the lower 2 bits of the TCP source port
number to the Queue# from the entry.
3 - 3-bit port based load balancing: add the lower 3 bits of the
TCP source port number to the Queue# from the entry.
Example 1:
If the incoming packet’s IP address matches the IP Address of the IP Address entry,
then the target receive queue is equal to:
Target queue = Queue# + TCP Port Number & Policy
If the source port number of this packet is 32763 (0x7FFB), then the resulting target
queue will be:
This packet will be delivered to Queue #3. The CPU that runs this particular queue
will handle the interrupt processing for this packet.
Example 2:
This setup is for receive side load balancing based on the TCPport number alone
without considering the IP address.
In this example, if the incoming packet’s source port number is 32763 (0x7FFB), then
the result target queue will be:
This is a typical setup for receive load balancing within a single host.
