High-Performance Cell Processor
The MXT3010 is the industry’s highest-performance programmable cell processing
engine. It offers the throughput normally associated with hardwired designs while
delivering all of the benefits of a programmable solution. Capable of supporting data
rates up to 800 Mbps, the MXT3010 can perform data path functions such as
segmentation/reassembly or traffic shaping for ATM interfaces running at up to
OC-12 speeds. With its efficient RISC processor, high-speed context switching,
and flexible cell scheduling system, the MXT3010 can easily integrate all current and
emerging ATM Forum traffic classes, including ABR, in a single application.
Developers can license prepackaged software products that run on the MXT3010
or may write their own custom software. MXT3010 software products include:
CellMaker
configurations with integrated ABR traffic management.
