Features
--------

-  `Integrated July 2016 DPDK release <http://www.dpdk.org/doc/guides/rel_notes/release_16_07.html>`__

   -  DPDK-vhost is depreciated pending a complete rework of the
      original integration and addressing of rx performance deltas.
   -  Patches required for DPDK 16.07:

      -  Correctly setting the Packet Type in the IGB, IXGBE and i40e
         drivers.
      -  Correctly setting checksum in the i40e driver.
      -  NXP DPAA2 PMD Driver.
      -  rte_delay (yield) functionality.

-  Add “in tree” plugins:

   -  IPv6 ILA.
   -  iOAM.
   -  Load Balancer.
   -  SNAT.

-  High-performance (line-rate) “neutron like” L4 port-filtering.

-  API refactoring - addressing some of the issues around JVPP bindings.

   -  Accommodating plugins
      `(e.g. NSH_SFC) <https://wiki.fd.io/view/NSH_SFC>`__
   -  Binding for `python <https://wiki.fd.io/view/VPP/Python_API>`__

-  LISP

   -  L2 LISP overlays
   -  Multitenancy
   -  Multihoming
   -  RTR mode
   -  Map-resolver failover algorithm

-  Support 64-bit vector lengths, huge shared-memory segments.

-  Dynamic IP Feature ordering

   -  IP Features can now specify features they appear before and after

-  16.09 Builds

   -  Ubuntu 14.04 LTS - Trusty Tahr
   -  Ubuntu 16.04 LTS - Xenial Xerus
   -  CentOS 7
   -  More information on `VPP wiki <https://wiki.fd.io/view/VPP/Installing_VPP_binaries_from_packages>`__

-  Performance, characterize and document performance for this release
   `(more information on CSIT page) <https://wiki.fd.io/view/CSIT>`__

   -  IPv4 and IPv6 Scale - performance tests.

      -  Bidirectional 10k/100k/1M flows.
      -  64B,570B, 1518B,9000B packet sizes.

   -  IPv6 iACL - performance

      -  DUT1 and DUT2 are configured with IPv6 routing, two static IPv6
         /64 routes and IPv6 iAcl security whitelist ingress /64 filter
         entries applied on links.
      -  TG traffic profile contains two L3 flow-groups (flow-group per
         direction, 253 flows per flow-group) with all packets
         containing Ethernet header, IPv6 header and generated payload.
         MAC addresses are matching MAC addresses of the TG node
         interfaces.

   -  L2XC VXLANoIPv4 - performance

      -  DUT1 and DUT2 are configured with L2 cross-connect. VXLAN
         tunnels are configured between L2XCs on DUT1 and DUT2.
      -  TG traffic profile contains two L3 flow-groups (flow-group per
         direction, 253 flows per flow-group) with all packets
         containing Ethernet header, IPv4 header with IP protocol=61 and
         generated payload. MAC addresses are matching MAC addresses of
         the TG node interfaces.

-  Documentation

   -  Autogenerated CLI documentation.
   -  Using doxygen to automate API/Node documentation.
   -  `(available online) <https://docs.fd.io/vpp/16.09/>`__
