Dear members, We're glad to announce INT v2.0 was cut and is available at: https://github.com/p4lang/p4-applications/blob/master/docs/INT_v2_0.pdf The major changes in v2.0 include * Domain specific extension * Provides a lot of flexibility, adopted by IETF IOAM as well * in INT it also allows 'source-only' metadata for Edge-to-Edge use cases * New transports * IPv4/GRE * new UDP encap using a new UDP destination port * VXLAN <-> VXLAN GPE conversion * Metadata * Timestamps in 8B * Level 2 Port ID (e.g., virtual interface) * shared buffer occupancy * Introduced XD, MD, MX application modes Next steps: * Telemetry report spec 2.0 * INT v2.1 * define MX-type header * define CL (Closed Loop) type for NIC closed-loop control use cases * define Destination header, if needed * (all three has a commonality: no header addition by transit nodes) * ipv6 hop-by-hop extension Thanks a lot for all your great inputs. We will soon announce the next meeting schedule. JK Lee Mukesh Hira

- Domain specific extension
   - Provides a lot of flexibility, adopted by IETF IOAM as well
   - in INT it also allows 'source-only' metadata for Edge-to-Edge use
   cases
- New transports
   - IPv4/GRE
   - new UDP encap using a new UDP destination port
   - VXLAN <-> VXLAN GPE conversion
- Metadata
   - Timestamps in 8B
   - Level 2 Port ID (e.g., virtual interface)
   - shared buffer occupancy
   - Introduced XD, MD, MX application modes

- Telemetry report spec 2.0
- INT v2.1
   - define MX-type header
   - define CL (Closed Loop) type for NIC closed-loop control use cases
   - define Destination header, if needed
   - (all three has a commonality: no header addition by transit nodes)
   - ipv6 hop-by-hop extension

Great job team - this is a big milestone for INT. It is really super to see it evolve and mature as more people use it.
