Feature	HLD Review Date	Test Plan Ready for Review ETA	Owner	Code Review Owner	Code Review Date	Test PR Ready for Review ETA	Design/ Code Master PR	SAI Change	Priority/Conf (High/Low)	Description
Active Active ToRs HLD	Apr 15		MSFT							Link manager, Warm reboot support for active-active dual ToRs
Add SAI version check to SONiC build system HLD	Done		Nvidia	MSFT		Done	935 - Merged	No		SONiC is not designed to work in backward compatibility with older vendor SAI implementations. SAI headers that SONiC's synd daemon is compiled against are taken from OCP SAI repository while the actual libsai.so is taken from sonic-buildimage vendor's directory. This leads to a situation that sometimes SAI in sonic-sairedis repository is updated but vendor SAI in sonic-buildimage is not.
Add system date row to ‘show version’ HLD	NA		Nvidia		Done			No		Provide a baseline to improve debug flows
Added fan_drawer class support in PDDF	NA		BRCM	MSFT		NA	10213 - Merged	No		fan_drawer support was missing in PDDF common platform APIs. This resulted in 'thermalctld' not working and 'show platform fan' and 'show platfomr temperature' commands not working._thermal_list array inside PSU class was not initialized. Made changes to attach the PSU related thermal sensors in the PSU instance.
Align crmorch with sai_object_type_get_availability Deferred from 202111	Done		Nvidia					No PR 942		Will not require a new SAI API, but vendors will have to implement this API for using this functionality

Deferred Features to Next Release

Feature	HLD Review Date	Test Plan Ready for Review ETA	Owner	Code Review Owner	Code Review Date	Test PR Ready for Review ETA	Design/ Code Master PR	SAI Change	Priority/Conf (High/Low)	Description
System with zero port support HLD	Done		Nvidia	Juniper/ LinkedIn	Done		900; 109, 221, 1808 & 3663 - Merged, 1697 - Closed	No		Allows to bring up system and finish the init flow

Build Time Improvement HLD	Jan 31		BRCM	Nvidia (stepanblyschak)		Feb 29
Link Training HLD	Feb 8		BRCM			Feb 7	925 - Merged			Link Training is a process by which the transmitter and receiver on a high-speed serial link communicate with each other in order to tune their equalization settings. In theory, link training enables automatic tuning of the finite impulse response (FIR) filter for each channel in an application-specific integrated circuit (ASIC) to achieve the desired bit error rate (BER).In the SONiC system, the ODM vendors rarely provide pre-calibrated pre-emphasis for QSFP(DD) CR/KR modules, which could result in the link reliability issues. With this feature, both IEEE clause 72 and 93 will be activated to dynamically tune the transmitted signal to improve the link quality over the copper cables. This feature could be activated with or without AutoNeg.
Auto Neg Enhancement HLD	Feb 8		BRCM			Feb 14	924 - Merged			Autonegotiation is a signaling mechanism and procedure used by Ethernet over twisted pair or optical media by which two connected devices choose common transmission parameters, such as speed, duplex mode, and flow control. In the case of SONiC, this feature supports two different types of AutoNeg 1. QSFP(DD) CR/KR modules: This feature provides autonegotiation support for speed, FEC and TX_FIR, the LinkTraining will always be activated when autonegotiation is enabled, and users could enable standalone-link-training to activate the clause 72/93 when autonegotiation is disabled. 2. Native RJ45 ports of non-Gearbox design: This feature provides autonegotiation support for speed and duplex to the native RJ45 coppers if they're manageable by the SAI without external PHY drivers on the Gearbox.
SNMPd Enhancements	NA		BRCM				6276, 108, 220, 8130, 225 & 227 - All Open			Enable ipv6 snmpd support. Generate coldStart/warmStart trap based on reboot reason to differentiate. Removed default SNMP community public for security. Add strerror to SNMP file open failure. There is a possibility for snmpd try to open a device file (for reading statistics) which is already deleted by other applications.

To provide anycast gateway for host/VMs. Can be used independently, or with MCLAG to provide single gateway for MC-LAG member host. To provide the possibility for host VM mobility. Both IPv4 and v6
VLAN Stacking HLD	Reviewed on Jan 25		EdgeCore	Intel			915 - Open	Yes		This feature provides Q-in-Q and VLAN translation for service providers who carry traffic of multiple customers across their networks and are required to maintain the VLAN and Layer 2 protocol configurations of each customer without impacting the traffic of other customers.
Config Reload Enhancement: Introduce the Transaction Mechanism HLD	TBD		EdgeCore	Nvidia (Junchao-Mellanox)				No		In the current design of 'config reload', it does not mean the sonic configurations to be reloaded had been finished when the execution of 'config reload' has done. When the execution of 'config reload' is done, it is possible that some sonic services have not been fully populated and the system in terms of sonic services is not in ready state. It is just wasting time to initiate another 'config reload' transaction when the previous transaction has not been done. It is better to have a transaction protection to avoid that condition.
