4 VPP The Magic of Vectors Compute Optimized SW Network Platform Packet processing is decomposed into a directed graph of nodes packets move through graph nodes in vector graph nodes are optimized to fit inside the instruction cache vhost-userinput af-packetinput dpdk-input Packet 0 Packet Microprocessor arp-input cdp-input lldp-input mpls-input l-input ip-lookup* ip-input ip-lookupmulitcast ethernetinput...-nochecksum ip6-input Packet Packet Packet Packet 5 Packet 6 Packet 7 Instruction Cache Data Cache Packet 8 interfaceoutput ip-loadbalance mpls-policyencap ip-rewritetransit ip- midchain Packet 9 Packet 0 packets are pre-fetched into the data cache. * Each graph node implements a micro-nf, a micro-networkfunction processing packets. Makes use of modern Processor micro-architectures. Instruction cache & data cache always hot è Minimized memory latency and usage.
