New example for INT over UDP. Source-only DS metadata #67

Closed jklr closed 4 years ago

jklr commented 4 years ago

This PR also

  1. change the term hop-by-hop to INT-MD
  2. don't allow transit devices to set 'D' (discard) bit. It's only for the source to set.
  3. allow 'source-only' domain specific metadata and relax INT length requirements

Need to discuss/decide

Once we agree on the details of 'source-only' DS metadata, we will need to update the INT modes descriptions such that INT-MD and MX can also support edge-to-edge usecase via the source-only metadata.
