Features

Integrated July 2016 DPDK release
- 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)
- Binding for python
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
Performance, characterize and document performance for this release (more information on CSIT page)
- 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.
