APPLICATION EXAMPLE: Application-Specific Templates
Each template may have different flow control parameters. For instance, a system designer may
wish to configure a VCC traversing a network with all ER switches with a Rate Increase Factor
(RIF) and Rate Decrease Factor (RDF) = 1. However, a VCC traversing a network with switches
doing CI/NI (binary) marking will desire an RIF and RDF
be desired for these VCCs.
ABR algorithm in a hardware state machine. However, to provide flexibility
against minor changes in the immature TM 4.1 specification, the state machine is
programmable through Mindspeed-supplied ABR templates. These templates,
resident in SAR-shared memory, also provide a policy tuning mechanism for
interoperability and performance. Separate groups of VCCs can be assigned to
application-optimized templates according to their path through the network.
For optimal performance, the ABR Flow Control Manager implements the
