Posedge Switching & Routing Solutions by Posedge Inc

Product Description

With fiber to the home, node, basement, the functionality and
the complexity of a Gateway Processor and Ethernet Switches
increases significantly. The current generation gateway
architectures in CPE are not addressing multi gigabit data
rate with the growing functionality. These advanced
architectures would need to

• Route Multi-gigabits of data
• Provide sophisticated Quality of Service for applications like
IPTV, VoIP
• Handle very high number of flows
• Ultra low cost device adaptable to mass markets
• Needs to be highly programmable for changing
requirements
• Enable VPN, deep packet inspection to protect against
attacks

Posedge Wire-Speed Switching and Routing (WSP) Solutions
are highly scalable and configurable for various applications,
enabling network connectivity, switching and routing. The
engines offer complete offload of TCP / IP processing at
hardware level to achieve higher data rates without
burdeningthe host processor.

The WSP Processor architecture guarantees wire speed
secure routing of any size packets between Gigabit Ethernet
ports. The architecture is highly scalable for multiple Ethernet
ports or peripherals with other protocols like ATM and is
scalable for GPON and GEPON architectures. The
hardware/software partitioning and the partitioning of software
between Host Processor and Embedded modules ensure that
WSP software can be very easily integrated into customer’s
existing software.
