Figure 4: Link aggregation sublayer (according to IEEE 802.3ad)
The link aggregation sublayer is composed of the following functions:
• Frame distribution:
This block takes frames submitted by the MAC client and sends them for transmission on
the appropriate port based on a frame distribution algorithm employed by the Frame
Distributor.
Frame distribution also includes an optional Marker Generator/Receiver used for the
Marker Protocol. Ethernet Routing Switch 8800/8600, only implements the Marker
Receiver function. For details about the frame distribution algorithm, see
distribution algorithm
• Frame collection:
This block passes frames received from the various ports to the MAC client. Frame
collection also includes a Marker Responder which is used for the Marker Protocol.
• Aggregator Parser/Multiplexers:
During transmission operations, these blocks pass frame transmission requests from the
Distributor, Marker Generator, and Marker Responder to the appropriate port.
