New Features¶

• Currently, when a VNFFG is created, Tacker create new port-pairs,port-pair-groups, port-chains and flow-classifiers. This patch willlet a new VNFFG use existing port-pair-group if it already existed.User can create several VNFFGs that can go through a VNF.

• This feature adds ‘symmetrical’ as a property of forwarding path,so users can set ‘symmetrical’ value to ‘true’ or ‘false’ to changethe symmetrical value of a port chain in networking-sfc.

• Support creating VNFFG without flow-classifier

• Add dnsmasq and qos support for OpenWRT VNFM mgmt driver.

• This patch will add VNFFG support for NS. In NSD, users can describe VNFDsand nested VNFFGD inside. When NS is created, VNFs and VNFFG are alsocreated.

• Support shared vim for policy action execution

• Added placement policy support. Operator can specify below placementpolicies in addition toaffinity to VDU’s:

  • anti-affinity

  • soft-affinity

  • soft-anti-affinity

  Note: There is a known issue in nova thatlate anti-affinity check doesn’t workin multi-cells environment. So it is highly recommended to deploy nova in single cellenvironment until this issue is resolved in multi-cells environment.

Upgrade Notes¶

• Change cirros image from 0.3.5 to 0.4.0.

• Because this version uses the tacker service tenant to manage the fernet key,please remove the registered VIM before upgrading this version.The upgrade steps are as follows.1.Delete the registered VIM. If there is a VNF instance on the VIM,you need to delete the VNF instance first.2.Upgrade with this version.3.Register the deleted VIM.

Bug Fixes¶
