Features for Release VPP 18.07¶
This section lists those features that became available in VPP Release 18.07:
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
