Overview

The ABM-P PXF 4336 Version 1.1 is Infineon’s new generation ATM Buffer Manager device. It addresses the performance needs of new multi-service platforms with combined ATM cell and packet-handling applications. The ABM-P manages ATM traffic flowing through multi-service platforms in which voice, video, and data traffic converge.

Features

• ATM Traffic Management processing support up to STM-4/OC-12 equivalent bandwidth

• Throughput at UTOPIA Interface up to 687 Mbit/s transmit, 795 Mbit/s receive

• Speed-up factor relative to STM-4/OC12: 1.32

• Uni-directional mode with combined resources of both directions (optional)

• 256K cells buffer per direction (configurable in guaranteed and shared buffer)

• Up to 16384 connections arbitrarily assignable to queues for sharing connections and saving resources

• Up to 8192 queues per direction, individually assignable to schedulers and to traffic classes

• Up to 128 Scheduler Blocks (SB) per direction with programmable service rates, individually assignable to UTOPIA ports

• The ABM-P is cascadable to provide up to 512 schedulers, 32K queues, and 1M cell memories per direction

• Up to 16 traffic classes with individually-selectable thresholds for highest service differentiation

• Up to 48 ports per UTOPIA Interface

• Standards-compliant support for the following ATM Forum service categories: CBR, rt-VBR, nrt-VBR, GFR, ABR (EFCI, CI/NI relative marking, ER, VS/VD, RSC), UBR, UBR+

• Generic PHB (Per Hop Behavior) characteristics are configurable (PHB traffic class is not standardized)

• Configurable cell-address translation modes
