Release Progress Tracking 202106

202106 Features Tracking

Feature	HLD Review Date	Owner	Code Review Owner	Code Review Date	Code PR Status
Telemetry for Multi-ASIC		MSFT	Intel		Single telemetry sever to aggregate data from multiple Redis DB
Dynamic policy based hashing	3/22/2021	Nvidia/MSFT	MSFT/Aviz		Hash packets on custom fields
DHCP relay IPv6 support	03/18/2021	Nvidia	BRCM		Currently DHCP relay supports only IPv4. The idea is to extend the support to IPv6 and it should work for both as the same time. Also, currently DHCP relay is enabled only based on the Type in the METADATA and it must be ‘ToRRouter’. We will remove this restriction and will integrate it with copp manager so user can decide if to have DHCP relay or not regardless of the device type
App extension with Orchagent/SWSS		Nvidia	BRCM/ MSFT		2nd phase of the application extension: dynamically adds logic to swss/orchagent so additional use applications can be developers developed based on SONiC application extension infrastructure. For example: dynamic policy based hashing

Inband mgmt VRF	2/24/2021	DELL	MSFT		HLD pending for review (#638)
Sample Rate on mirror		Innovium	BRCM/ LinkedIn		Ability to sample on a mirror. i.e, instead of mirroring all the packets, just send 1 out of n packets. This involves adding SONiC support  for Mirror session attribute SAI_MIRROR_SESSION_ATTR_SAMPLE_RATE.
Sflow with remote collector		Innovium	BRCM/ Nvidia		Currently, SONiC supports sending sFlow samples to local CPU. Add support to send the samples to a remote collector  using a mirror session of type (SAI_SAMPLEPACKET_TYPE_MIRROR_SESSION).
V4/V6 L3 ACL optimization	March	Innovium	BRCM/ LinkedIn		Currently SONiC uses separate ACL tables for L3 and L3v6 RACLs. In some ASICs, if a user wants both v4 and v6 rules, they would end up using two hardware ACL tables instead of one. The proposal is to give the platform the ability to mention if they want to support L3 and L3V6 ACLs in the same hardware ACL Table. This approach has been taken in the community for Mirror ACL tables but not for L3 ACLs. We are extending this to L3 ACLs as well.
