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
NVGRE/GRE HLD	Done		Nvidia	Intel/ Dell			869	Yes		NVGRE is a Layer 3 tunneling protocol that utilizes a standard GRE header to encapsulate a Layer 2 packet.
System with zero port support HLD	Done		Nvidia	Juniper	Jul 13: ready		900; 109, 1697, 221, 1808, 3663	No		Allows to bring up system and finish the init flow
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
Move Nvidia syncd and pmon to Debian11- "Bullseye"	Done		Nvidia			Jan 30		No		Migrate syncd and pmon containers to Debian 11 - "Bullseye"
Dynamic Policy Based Hashing (edit flow) HLD	Done	Jan 30	Nvidia		Jan 30	Feb 15	909	No		Dynamic policy based hashing with edit flow
counter delay via config_db and not via systemd HLD	Done	NA	Nvidia		Feb 28	NA	918	No
Route Flow counters (based on generic counters) HLD	Done(merged)		Nvidia	Aviz	Mar 15	Mar 30	908	Yes Need this API  implemented
hostcfgd Redesign-split hostcfgd into multiple services	Jan 15	NA	Nvidia	Aviz	Mar 15	NA		No		Currently hostcfgd is handling a lot of tables and this leads to performance issues. This has lead to many bugs like 8619. So It is necessary to split hostcfgd into multiple services.The requirement is to come up with a design of how to split hostcfgd and what approach to use, either multi threaded or multi process. Based on design approval this needs to be implemented
Password Hardening HLD	Done		Nvidia	MSFT			874	No		a user password is the key credential used in order to verify the user accessing the switch and acts as the first line of defense in regards to securing the switch. The complexity of the password, it's replacement capabilities and change frequency define the security level of the first perimeter of the switch. Therefore - in order to further improve and harden the switch - a secure mechanism is required to enforce PW policies.
Queue statistics based on queue configurations and not max	TBD		Nvidia	MSFT	Jan 30		2143	No		Performance optimization to query only relevant queue in MC aware mode (8-15 are unused)
Add system date row to ‘show version’	NA		Nvidia		Feb 28			No		Provide a baseline to improve debug flows
Command for showing specific MAC from DB	NA		Nvidia	MSFT	Jan 30		1982	No		show mac –verbose fetches the whole FDB table When we have large table of Mac the respond will take very long time
Extend auto tech support for memory threshold	Done on 2/22/2022		Nvidia				939	No		Important when debugging production networks
Add SAI version	Done		Nvidia	MSFT		Done	935	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.

CMIS Diagnostics HLD Deferred from 202111	Reviewed on 10/5		BRCM	Dell/ Nvidia/ Google	Oct21 29		876	No		Introduce the CMIS4 transceiver-specific diagnostic test to help users narrow down the root cause of link failures. Scope of the change: 1) sonic-platform-daemons/sonic-xcvrd: Add a new subprocess to subscribe CMIS diag requests and either update DIAG control or post the test result to the RedisDB. 2) sonic-platform-common/sonic_platform_base: Add a generic QSFPDD/CMIS4 parser/handler to sfp_standard. [sfp_standard.py]py 3) sonic-mgmt-common: Add YANG and REST transformer codes for CMIS DIAG
System Ready Enhancements HLD Deferred from 202111	Reviewed on 10/5		BRCM	Dell/ Nvidia	Sep21 29		875, 930	No		Today there is no easy way to know when the device is ready in terms of control/dataplane. The change allows declaration of System ready (Syslog/CLI) when all the services(dockers+host) are up and ready. Also define a framework for each service to declare itself ready based on their application criteria.
Build Time Improvement HLD	Jan 31		BRCM	Nvidia (stepanblyschak)		Feb 29
Link Training HLD	Feb 8		BRCM			Feb 7	925			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			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			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.
SONiC fanout support Deferred from 202111	NA		MSFT	MSFT				No		Change fanout switch o.s to SONiC
100% SONiC YANG model Deferred from 202111	NA		MSFT	MSFT/ YANG WG	Sep21 30		Yang Project	No		Build a full and complete YANG model for SONiC configDB
Deprecating Python2 platform daemons Deferred from 202111	NA		MSFT	MSFT	Aug21 30			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. Question: Will there be new platform APIs to be added in 202111? @Guohan to confirm
MACSEC enhancement: primary & fallback case HLD Deferred from 202111	Done		MSFT	BRCM Juniper	N/A		652	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.

L2 Dot1Q tunneling support	TBD		EdgeCore
VLAN Stacking HLD	Reviewed on Jan 25		EdgeCore	Intel			915	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.
EVPN-MH Phase #1	TBD	N/A	EdgeCore	Nvidia	Jan 1	NA		Yes
