SONIC SwSS Newbie

[Ahmed Selim]

Hi All,
I am a newbie to SONiC (SwSS).

I have looked at the architecture and began by tracing the code like any C++ project, from main function at orchagent(main.cpp), and here is what I came up with so far (see file attached).

I am currently working with the 202111 release on Ubuntu Server 18 VMWare.

# My questions:

1. Correct me if I am wrong or misunderstood something.

2. I need some references/documentation/videos about sonic for newbies to have a solid ground to understand the workflow better.

3. I have basic knowledge about Networking, How far should I know to work with SONiC?

4. Is there a better way to debug my work or trace the code in sonic, other than SWSS_LOG_DEBUG(...)?

5. It would be great if I found others who can peer program, to facilitate learning and work closely together.

Thanks

Hi Ahmed,

 

You’ve captured the flow pretty well in the diagram. Please find some feedback

 

1. CLI/RestAPIs writes to DB and portmgrd subscribes from config_DB.
2. Portmgrd/portsyncd is recently changed and all incremental updates to PORT Table is handled *only* by portmgrd.
3. You can refer this page for the Sonic Architecture - Architecture · sonic-net/SONiC Wiki (github.com). Sonic wiki also has references to CLI and other useful components
4. Logging is the best option although you can also use ‘gdb’.
