Hardware Design Guide
Flow Control Bus
The MSF Flow Control Bus passes CSIX-L1 flow control CFrames between two network
processors or between a Switch Fabric and a single network processor. The bus is implemented as
two independent unidirectional buses. It uses LVDS signaling with the same clocking rate as the
MSF receive and transmit channels and has a 4-bit data bus — yielding an available bandwidth
equal to 25 percent of the receive and transmit channels.
The Flow Control Bus can be configured in one of two modes:
When the IXP2800 or IXP2850 network processor is configured in Dual Chip, Full Duplex Mode,
the egress IXP28XX network processor automatically forwards CFrames received from the Switch
Fabric across the Flow Control Bus to the ingress IXP28SS network processor. Additionally, the
egress IXP2800 or IXP2850 network processor sends incoming and outgoing Link Level flow
control information across the Flow Control Serial Bus to the ingress IXP28XX network processor.
When the IXP2800 or IXP2850 network processor is configured in Simplex Mode, the Flow
Control Bus signals are connected directly to the Switch Fabric. The egress IXP2800 or IXP2850
network processor sends flow control CFrames directly to the Switch Fabric, and the Switch Fabric
sends flow control CFrames directly to the ingress IXP2800 or IXP2850 network processor.

Dual Chip, Full Duplex Mode for applications where the Fabric Interface uses the transmit and
receive channels to pass flow control CFrames.
Simplex Mode for applications where the Fabric Interface is designed to use the Flow Control
Bus to pass flow control CFrames.
