  1. Network Processor • Programmable semiconductor devices for network oriented processing and switching • Helps new technologies get to market faster • Attempts to do for networking what WinTel did for PC • A business projected to grow to more than $600 million by 2002, according to Dataquest General Purpose Processor High performance Low cost Highly flexible Fast time-to-market Network Processor Good Flexibility, Time to Market Expensive, slow Large R&D expenses Short market window Poor Custom ASICs Poor Good Price/Performance

  2. Network Processors Markets • A high-layer packet-analysis and forwarding function currently served by ASICs • A control function for handling multiple routing and switching channels, usually served by a RISC device such as the 960 or StrongARM • An application processor function for specialized duties such as quality-of-service (QoS) bit assignment and virtual-private-network tunnel creation. • In some cases, the network processor offloads critical instructions from the host processor in a system, thereby improving throughput. In other cases, these new processors can replace the host CPU.

  3. Network Processors can do -- in hardware at wire-speed • Routing (L3 switching, L4 switching, MPLS, multi-layer switching, etc.) • Multi-protocol support for LAN and WAN integration • Bandwidth shaping to create CoS and optimize expensive WAN bandwidth • Setting of precedence bits to map CoS into the Internet • Sophisticated QoS support to help provide reliable Voice over IP transmission • High-speed evaluation of QoS tags to help enhance Policy Based Network Management • Per flow queuing and weighted fair queuing • IP multicast for scalable push and multimedia • Mix and convert frames to cells • Network address translation for network security and simplified IP addressing • IP accounting for network design and billing • IP tunneling to create Internet VPNs
