2.5.7 ABR Flow Control Manager
28236-DSH-001-B
The ABR Flow Control Manager operates in conjunction with the xBR Scheduler
to control the rate of ABR channels. The CN8236 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 conformance ABR behavioral
responses to network and connection states. The CN8236 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 TM 4.1 specification.
Mindspeed provides the initial templates, which can be customized by the
user later, shortening developmen
