2.5.7 ABR Flow Control Manager
28234-DSH-001-B
The ABR Flow Control Manager operates in conjunction with the xBR Scheduler
to control the rate of ABR channels. The RS8234 implements the TM 4.1
specification in a template-controlled hardware state machine. Mindspeed
provides an initial set of templates which reside in SAR shared memory. The
information within these templates define conformant ABR behavioral responses
to network and connection states. The RS8234 generates ABR Source traffic,
including internally generated RM cells, according to the template instructions.
The reassembly coprocessor and the Flow Control Manager collaboratively act as
a fully compliant ABR Destination Terminal.
These templates provide three significant benefits to the user:
1.
2.
3.
Since they control the Flow Control Manager state machine, they can be
optimized for specific applications.
The programmability of the templates insulates the hardware from changes
in the TM 4.1 specification.
Mindspeed provides the initial templates, which may be customized by the
user later, which shortens developmen
