LF_DPDK17_Flexible and Extensible support for new protocol processing with DPDK using Dynamic Device Personalization

  1. 1. Brian Johnson, Intel® Corporation Andrey Chilikin, Intel® Corporation DPDK Summit - San Jose – 2017 Flexible And Extensible Support for New Protocol Processing with DPDK using Dynamic Device Personalization #DPDKSummit
  2. 2. 2 Network Landscape
  3. 3. 3 Network Landscape Enterprise GiLANWireless Wireline
  4. 4. 4 Dynamic Device Personalization (DDP) Dynamic Device Personalization (DDP) profiles for Intel® Ethernet 700 Series enables run-time updating and configuration of parse graph to expand or modify protocol support allowing early adoption of new technologies Example: u Default Tunneling protocol support u VXLAN, GENEVE, NVGRE, MPLS, VXLAN-GPE currently supported but limited by hardware resources u Dynamic Device Personalization enables 1. Loadable profiles for packet classification for additional or modification of existing protocols u e.g. MPLSoGRE, GTP-U/GTP-C, PPPoE, QUIC, ESP, AH 2. Configurable tunnel filters for traffic steering u Steering packets to VM queues on QinQ/tunnel ID Load Distribution Software Worker 0 Worker 1 Worker n Worker 0 Worker 1 Worker n External traffic (e.g. GTP-U/GTP-C) External traffic (e.g. GTP-U/GTP-C) Host Software analyzes and distributes packets (without DDP) NIC Hardware with DDP enabled Profile and configured traffic steering Packet analyzes and distribution is done on NIC with additional Rx Descriptor Data
  5. 5. 5 Dynamic Device Personalization DPDK APIs* u rte_pmd_i40e_get_ddp_list() get the list of registered profile(s) u rte_pmd_i40e_process_ddp_package() download dynamic device personalization profile to the device and register profile rollback dynamic device personalization profile and un-register it u rte_pmd_i40e_get_ddp_info() request information about a profile without downloading it to the NIC * Requires XL710 firmware version 6.01 https://downloadcenter.intel.com/product/75021/Intel-Ethernet-Controller-XL710-Series
  6. 6. 6 Dynamic Device Personalization: Without vs. With, GTP-U example Default FVL6 processing (without Personalization profile): DA SA IPv4 UDP GTP TEID IPv4 TCP PAY Parsed fields Payload FVL6 with Personalization profile applied: DA SA IPv4 UDP GTP TEID IPv4 TCP PAY Parsed fields Payload RSS RSS GTP-U is unknown flow type, so no RSS, FDIR or other filters are possible on encapsulated frame GTP-U flow type is defined, encapsulated frame fields (including GTP TEID) can be used for RSS, FDIR. Encapsulated 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 configuration. RSS RSS RSS Packet type: UDP in IPv4 Packet type: TCP in GTP-U
  7. 7. 7 Without Dynamic Device Personalization Profiles Loaded DDP
  8. 8. 8 With Dynamic Device Personalization GTP, QUIC & IPsec Profiles Loaded DDP
  9. 9. 9 With Dynamic Device Personalization RSS Queue Regions Assigned DDP
  10. 10. 10 Summary u Dynamic Device Personalization can be used on any OS supported by DPDK u For example, QUIC protocol classification on both Windows and Linux OSes u Dynamic Device Personalization allows a DPDK application to enable identification of new protocols, for example, GTP, PPPoE, QUIC, MPLSoGRE, SRv6, etc without requiring a reboot due to changing hardware or firmware updates. u Allows for existing Parse Graphs to be modified to support new usage models as they are defined enabling faster time to market for DPDK enable applications. DPDK on Microsoft Windows DPDK on Linux
