4 Dynamic Device Personalization (DDP) Dynamic Device Personalization (DDP) profiles for Intel Ethernet 700 Series enables rn-time pdating and configration of parse graph to expand or modify protocol spport allowing early adoption of new technologies Example: Defalt Tnneling protocol spport Loadable profiles for packet classification for additional or modification of existing protocols 2. Worker n Worker 1 Load Distribtion Software Host Software analyzes and distribtes packets (withot DDP) External traffic (e.g. GTP-U/GTP-C) VXLAN, GENEVE, NVGRE, MPLS, VXLAN-GPE crrently spported bt limited by hardware resorces Dynamic Device Personalization enables 1. Worker 0 e.g. MPLSoGRE, GTP-U/GTP-C, PPPoE, QUIC, ESP, AH Configrable tnnel filters for traffic steering Steering packets to VM qees on QinQ/tnnel ID Worker 0 External traffic (e.g. GTP-U/GTP-C) Worker 1 Worker n NIC Hardware with DDP enabled Profile and configred traffic steering Packet analyzes and distribtion is done on NIC with additional Rx Descriptor Data 4

5 Dynamic Device Personalization DPDK APIs* rte_pmd_i40e_get_ddp_list() get the list of registered profile(s) rte_pmd_i40e_process_ddp_package() download dynamic device personalization profile to the device and register profile rollback dynamic device personalization profile and n-register it rte_pmd_i40e_get_ddp_info() reqest information abot a profile withot downloading it to the NIC * Reqires XL710 firmware version

6 Dynamic Device Personalization: Withot vs. With, GTP-U example SA IPv4 UDP RSS DA RSS Defalt FVL6 processing (withot Personalization profile): GTP TEID IPv4 TCP PAY Packet type: UDP in IPv4 Parsed fields Payload GTP-U is nknown flow type, so no RSS, FDIR or other filters are possible on encapslated frame FVL6 with Personalization profile applied: UDP GTP Parsed fields TEID IPv4 TCP Packet type: TCP in GTP-U RSS IPv4 RSS SA RSS DA PAY Payload GTP-U flow type is defined, encapslated frame fields (inclding GTP TEID) can be sed for RSS, FDIR. Encapslated frame type is indicated on RX descriptor, for example, TCP in GTP-U or GTP-U echo message GTP-C flow type is defined as well and has separate RSS/FDIR configration. 6

10 Smmary Dynamic Device Personalization can be sed on any OS spported by DPDK For example, QUIC protocol classification on both Windows and Linx OSes DPDK on Microsoft Windows DPDK on Linx Dynamic Device Personalization allows a DPDK application to enable identification of new protocols, for example, GTP, PPPoE, QUIC, MPLSoGRE, SRv6, etc withot reqiring a reboot de to changing hardware or firmware pdates. Allows for existing Parse Graphs to be modified to spport new sage models as they are defined enabling faster time to market for DPDK enable applications. 10
