Figure 2: Intermediate Driver
Outbound Traffic Flow
The Broadcom Intermediate Driver manages the outbound traffic flow for all teaming modes. For outbound traffic, every
packet is first classified into a flow, and then distributed to the selected physical adapter for transmission. The flow
classification involves an efficient hash computation over known protocol fields. The resulting hash value is used to index
into an Outbound Flow Hash Table.The selected Outbound Flow Hash Entry contains the index of the selected physical
adapter responsible for transmitting this flow. The source MAC address of the packets will then be modified to the MAC
address of the selected physical adapter. The modified packet is then passed to the selected physical adapter for
transmission.
