PRS 64Gu
Packet Routing Switch
Target Markets and Applications
The AMCC PRS family of packet
routing switch products provides a
highly-integrated, non-blocking, and
scalable migration path for a wide
range of switch applications: in the
enterprise, with data center (web
caching, load balancing, security),
NAS/SAN and high-end LAN
products; in the wireless
infrastructure, with wireless
aggregation and base station
controller equipment; and in the
Metro/WAN, with access, edge and
transport switches.
The latest member of the PRS family,
the PRS 64Gu is an excellent fit for
applications requiring compact
design, to address card real estate
constraint or floor space restriction.
The PRS 64Gu enables design of
switch fabrics with up to 32 ports for
support of GE/OC-48c interfaces, or
eight ports for support of 10GE/
OC-192c interfaces, or any
intermediate combination.
High Throughput and
Non-Disruptive Migration
The PRS 64Gu Packet Routing
Switch provides a powerful engine
for high-throughput switch
applications and port speeds of up to
10-Gbps/OC-192c. The chip features
configurable fixed-size, fast packet
switching and is capable of
supporting either frame-based traffic
(through segmentation and
reassembly) or cell-based traffic.
Protocol-independent, it enables
non-blocking and scalable switch
fabrics offering 64-Gbps or 128-Gbps
core switch aggregate throughput.
Manufacturers using the PRS 64Gu
can benefit from IBM’s advanced
silicon technology and the proven
reliability, redundancy, and load
sharing features of the AMCC packet
routing switch technology. The
PRS 64Gu Packet Routing Switch
offers:
• 16 input ports and 16 output ports
(one chip); or 32 input ports and 32
output ports (two chips)
• 40-Gbps (one chip) or 80-Gbps
(two chips) aggregate user
bandwidth
• Up to four GE or one OC-48c per
port, or one 10GE or one OC-192c
per group of four ports
• Quality of Service (QoS) with four
levels of traffic priority and
programmable flow control
thresholds
• Packet lossless switchover
capability and efficient multicast
(replication at sending)
• Industry standard CSIX-L1
interface to Network Processors or
Traffic Managers
• Embedded high-speed serial links
at 2.5 Gbps for simpler wiring,
compact switch board design, and
common wiring rules across
multiple PRS-based switches
(PRS 64Gu, Q-64G, and so on)
• End-user evolution from/to other
PRS switch cores, using the same
line adapters (investment
protection)
