Mindspeed Technologies™ CX27470 Traffic Stream Processor (TSP)
is the second generation of the industry ’s first programmable traffic management
engine for gigabit-scale packet- and cell-based networking equipment. Coupled
with off-the-shelf PortMaker™ firmware applications or customized source code
solutions, the CX27470 delivers a proven, packet- and cell-based traffic
management solution that forms the foundation of sophisticated Quality
of Service (QoS) applications.
The protocol agnostic CX27470 TSP with an Octave™ uniprocessor pipelined
architecture and multiple hardware engines adapts the protocol and traffic
flow of up to 64K input traffic streams to managed traffic streams in an
output data path. Defining traffic streams as cells or packets enables the
CX27470 to excel in a wide range of ATM, Packet-over-SONET,
Frame Relay and Multi-Protocol Label Switching (MPLS)
applications from DS-3 to OC-48.
For OC-48 operation, two CX27470 TSPs are required. Each CX27470
processor offers PCI, POS Level 3 and UTOPIA interfaces, a 200 MHz core speed,
and 64-bit memory interfaces.
