Release notes for VPP 18.07 =========================== More than 533 commits since the 18.04 release. Features -------- Infrastructure ~~~~~~~~~~~~~~ - DPDK 18.02.1 - Complete rework of the dpdk-input node - Display rx/tx burst function name in “show hardware detail” - Improve buffer alloc perfomance - This is ~50% improvement in buffer alloc performance. For a 256 buffer allocation, it was ~10 clocks/buffer, now is < 5 clocks. - Add per-numa page allocation info to ‘show memory’ - Vectorized bihash_{48,40,24,16}_8 key compare - bihash_48_8 case: - Scalar code: 6 clocks - SSE4.2 code: 3 clocks - AVX2 code: 2.27 clocks - AVX512 code: 1.5 clocks - Pollable Stats - Stats are now available to a client in a shared memory segment and in the form of a directory, allowing very high performance polling of stats without directly querying VPP. VNET & Plugins ~~~~~~~~~~~~~~ - IGMP improvements - Enable/Disable an interface for IGMP - improve logging - refactor common code - no orphaned timers - IGMP state changes in main thread only - Large groups split over multiple state-change reports - SSM range configuration API. - more tests - IP: vectorized IP checksum - VXLAN : HW offload RX flow - Rework kube-proxy into LB plugin and add NATA66 - NAT: - Code refactor - Syslog - Multiple outside interfaces - Endpoint dependent filtering and mapping - ACL: - Tuple Merge algorithm cleanup and integration - Processing pipeline optimizations - Refactoring - Experimental AVF driver Host stack ~~~~~~~~~~ - Session: performance improvements, add support for connectionless transports, datagram reception and transmission - TCP: congestion control improvements and overall fixes - UDP: datagram mode - TLS async support Known issues ------------ For the full list of issues please refer to fd.io `JIRA `__.
