### What information was incorrect, unhelpful, or incomplete?

> SDP (Session Description [Protocol](https://developer.mozilla.org/en-US/docs/Glossary/Protocol)) is the standard describing a [peer-to-peer](https://developer.mozilla.org/en-US/docs/Glossary/P2P) connection. SDP contains the [codec](https://developer.mozilla.org/en-US/docs/Glossary/Codec), source address, and timing information of audio and video.

### What did you expect to see?

Unique id is important, I guess?

I was trying to figure out if cache for signaling is possible, and I found information unique or always changes so far is just `sess-id`. Is this correct?

### Do you have any supporting links, references, or citations?

` is a numeric string such that the tuple of , , , , and forms a globally unique identifier for the session. The method of allocation is up to the creating tool, but a timestamp, in seconds since January 1, 1900 UTC, is recommended to ensure uniqueness.`
