Posedge Switching and Routing Solutions

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.

Posedge Wire-Speed Switching and Routing (WSP) is an enterprise class modular, scalable network software module for managed Home/SMB gateways, routers, switches to perform Layer2 - Layer4 switching and routing. It significantly accelerates the performance of common protocols like DNAT, SNAT, VLAN and PPPoE in Host processor based communication processors. Posedge WSP implements very sophisticated QoS algorithms amenable for Software only (and Coprocessor based HW) implementations. NFP performs state-full classification / modification / scheduling of packets to achieve higher throughput across multiple ports. The slow path of the software sets up tables to aid the fastpath processing of packets. It provides framework for advanced protocols like IPSec and for processing advanced Application level gateways (ALG). The architecture allows very high number of flows without degradation in performance and supports numerous industry-standard RFC’s and protocols. Posedge WSP is developed as a Loadable Kernel Module for Linux operating system for facile integration.
