Desc ription
The 89TTM553 is a flow-based traffic management co-processor
that can be used in conjunction with the 89TTM552.
It has two major functional parts: the queue manager (QM) and the
FLQ scheduler. The QMis responsible for all the non-bandwidth func-
tions, which include managing up to 1 Mllion queuing structures,
handling cell and packet arrivals and departures fromthese queues, and
maintaining a database of congestion management and statistics
parameters for each flow queue (FLQ). The FLQ scheduler is respon-
sible for managing the FLQ bandwidth functions.
The 89TTM553 FLQ scheduler supports traffic scheduling on up to
1Mdiscrete flows. In addition to the scheduling levels provided by the
89TTM552, the 89TTM553 provides one or two levels of additional
scheduling hierarchy. It also provides guaranteed mnimumrate,
maximumrate capping, excess rate distribution using weighted fair
queuing (WFQ), byte rate shaping, and dynamc configuration adjust-
ments.
The 89TTM553 stores all the flow-based parameters (and state infor-
mation) that are made available to the 89TTM552 for flow-based
processing. When the 89TTM553 is used with the 89TTM552, conges-
tion and bandwidth management features are enabled at the flow level
as well as at the aggregate-flow level.
89T T M55x Features
N
Deterministic performance at 10Gbps wire-speed (35Mcps)
regardless of the number of flows, traffic size, and patterns.
N
Up to 256 megabytes of external memory buffer space
(equivalent to a 210ms buffer at 10Gbps).
N
Support (Rx and Tx) for industry-standard SPI-4 phase 2,
NPF Streaming Interface, and CSIX over LVDS.
N
Hierarchical queuing and precise scheduling:
– Traffic management flexibility.
– Support for up to 4K aggregate flow queues (AFQs), 1K port
queues (PQs), 2K arrival reassembly queues (ARQs), and 1K
output queues/channels (OQs) with no external memory
required. Configurable AFQ-to-port assignments.
– Support for up to 1Mdiscrete flows (FLQs), with queuing for
each flow using external memory. Configurable mapping of
FLQs into aggregate flow queues.
– Two-level FLQ scheduling mode that supports up to 128K or
256K virtual pipe or subscriber queues with up to 8 or 4 CoS
priority queues each.
– Accurate byte-rate shaping at the FLQ, AFQ and port levels.
N
Multiple levels of buffer congestion management.
– Hierarchical queue structure and thresholding.
– Congestion indication.
– Dynamc adjustment of thresholds during periods of congestion.
– Packet discard (PD).
– Weighted randomearly discard (WRED).
– Local congestion indication (CI).
