Feature	HLD Review Date	Owner	Code Review Owner	Code Review Date	Code PR Status	SAI Change	Priority/Conf (High/Low)	Description
Deprecating Python2 platform daemons	No HLD	MSFT [Vendors will have to support]	Nvidia-tbd	Need Info		N/A		All platform daemons will run using Python 3. Python 2 support  will be removed. Vendors must build and install Python 3 sonic-platform packages. N/A – No HLD. Some vendors are already building/installing Python 3 sonic-platform packages, so there are a number of examples
MACSec support in Chassis	03/30/2021	MSFT	BRCM/ Juniper	26 - Open
MACSEC enhancement: primary & fallback case	3/30/2021	MSFT	BRCM/ Juniper		403, 193, 5700, 18, 22, 434, 1475, 1474, 713, 714, 715,716, 717, 719, 704, 684, 722 & 755 - Merged	No		MACsec can enable primary and fallback Connectivity Association Keys(CAK) at a same time. Meanwhile the primary and fallback key can be switched or replaced without any outage.
New branch creation for Debian11	(No HLD)	MSFT	MSFT			No		Create initial testing image and Debian 11 branch for community to integrate with respective platform drivers, SAI etc. Debian11 support is targeted for 202112 release. [Will be continued in 202112]
(Test) Testbed v2	Reviewed	MSFT	Confirm with Test subgroup	TBD		No		Improve testbed and deployment management
Enabling IS-IS in the dataplane	Need Info	Metaswitch	Confirm with MPLS WG	Need Info		Yes (new enum value)		Getting IS-IS PDUs to the control plane. To be discussed in sonic-mpls-workgroup
Class-based forwarding	Need Info	Metaswitch	Confirm with MPLS WG	Need Info		Yes		Policy-based tunnel selection.To be discussed in sonic-mpls-workgroup(Might move to 202112 release)
App extension with Orchagent/SWSS		Nvidia	BRCM/ MSFT	Deferred		No	Low	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 Feature on hold for further calcification
(Test) Upgrade to Python3 compliance	Not required	MSFT	Confirm with Test subgroup	Deferred		No		Pytest to use python3 as python2 is at end of life.
(Test) Ansible 2.10 upgrade	Not required	MSFT	Confirm with Test subgroup	Deferred		No		Pick up new features in ansible 2.10.
Link Training	Deferred	MSFT	Nvidia - tbd BRCM- tbd DELL - tbd	Deferred		No [To be confirmed]		Enable and disable link training per port.
Sample Rate on mirror	Need ETA	Innovium	BRCM/ LinkedIn	Deferred		No	Low	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	Need ETA	Innovium	BRCM/ Nvidia	Deferred		No	Low	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 Need ETA	Innovium	BRCM/ LinkedIn	Deferred		No		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.
RPVST+	10/20/2019	BRCM	Deferred	Deferred		No	Conf: High Pri: Low	Best Effort - 202106 Rapid traffic re-convergence per vlan (< 500 ms) following the failure of a bridge or bridge port. Incl BPDU and Root Guard functions, and IS-CLI support (PVST+ also)
Kernel programming performance enhancement	4/28/20 -> rejected New ETA: TBD	BRCM	MSFT/ DELL/ Intel	Deferred		No	High	Replace system() calls with netlink calls (nlapi -> libnl3) (HLD needs some re-work and re-review)
Static Anycast Gateway	TBD	BRCM	Intel - tbd	Deferred		No	High	L3 MC-LAG feature to configure the gateway address on both peers
BFD (SW - 100ms interval from FRR)	Need Info	BRCM	Nvidia - tbd	Deferred		No	BFD	Bidirectional Forwarding Detection - routing OAM feature, linked to BGP neighbor detection. This was submitted before (HLD, code), but needs to change to reflect FRR 7.5 and bgpcfgd changes
Thresholds (statistics)	7/30/2019	BRCM	Deferred	Deferred		No	Low	Best Effort - 202106 Configure a threshold on supported buffers in ingress and egress. A threshold breach notification (entry update in COUNTERS_DB) is generated accordingly.
UI Content (UMF client)	TBD	BRCM	Nvidia - tbd	Deferred		No	High	Big catch-up of UI's using the Management Framework - incremental work (i.e. not all or nothing)
DPB Reconcile	TBD	BRCM	LinkedIn - tbd Need to confirm with DPB WG	Deferred		No	Low	Broadcom has an internal parallel implementation of DPB. This is based upon the Community design and code, but has diverged. We need a catch-up reconcile.
Dynamic CoPP reconcile	TBD	BRCM	MSFT/DELL	Deferred		No	Low	Broadcom has an internal parallel implementation of Dynamic CoPP. This is based upon the Community design and code, but has diverged. We need a catch-up reconcile.
Mgmt FW Phase 3	TBD	BRCM	MSFT/ BRCM/ DELL	Deferred		No	High	Next set of infra enhancements to the Management Framework, including (but not limited to): - - Standard interface-naming - gNMI subscriptions (ON_CHANGE etc) - OC-YANG versioning - Show running - Audit logging - Memory/performance enhancements - RBAC with AAA
Routed sub-interface reconcile	TBD	BRCM	Alibaba/ MSFT-tbd	Deferred		No	Low	Broadcom has an internal parallel implementation of Routed sub-interfaces. This is based upon the Community design and code, but has diverged. We need a catch-up reconcile.
MultiDB reconcile	TBD	BRCM	Alibaba/ MSFT-tbd	Deferred		No	Low	Broadcom has an internal parallel implementation of Multi-DB. This is based upon the Community design and code, but has diverged. We need a catch-up reconcile.
CPU Queues	2/16/2021 (30mins)	BRCM	Intel-tbd	Deferred		No	Conf: High Pri: Low	Ability for manage/view CPU egress queues on the CPU port - basis for other monitoring features/enhancements (Threshold/Snapshot)
ACL enhancements: Policing, DHCP/PCP remark, L2	TBD	BRCM	MSFT	Deferred		?	Pri: Low	Best Effort - 202106 Use Flow-based Services framework to add ACL enhancements, including L2 ACLs, QoS re-marking and policing, and mirroring match enhancements. Included FBS Framework Comprises: - - ACL match extensions (e.g. L2 fields) - MQC equivalent config framework - DSCP, COS Remarking and Policing QoS actions - Flow-based forwarding (e.g. PBR) - ACL-based CoPP rules - Reconcile rules from different policies on the same interfaces (port, PO, VLAN) - Ingress vs. egress binding - Re-factored code to use Flow-based services - etc
ARP Refresh	TBD	BRCM	MSFT Dell - tbd	Deferred		No	Pri: High	More performant alternative to the current ARP Refresh script, implemented in SWSS. Initial design discussed with MSFT - based upon this reworked to move some functions to nbrmgrd (from neighsyncd)
Gearbox part 2		BRCM	MSFT (confirm with MACSEC/gearbox WG)	Deferred		Yes	Pri: High	Best Effort - 202106 We found deficiencies in part 1 during the AS5835 bring-up - these need fixes in both SONiC and SAI. MSFT (Guohan) is aware of these, but we need to close on the details
libebpf support and usage	TBD	BRCM	MSFT - tbd/ Alibaba	Deferred		No	Pri: Low	Best Effort - 202106 Scaling enhancement - filters/reduces netlink processing load by: - kernel extensions - user-space access library - Client application usage (e.g. teamd)
