+# AT&T Workflow
+
+You can find a complete description of the SEBA workflow for At&t in [this document](https://docs.google.com/document/d/1nou2c8AsRzhaDJmA_eYvFgd0Y33KiCsioveU77AOVCI/edit#heading=h.x73smxj2xaib). This pages focus exclusively on the internals details of the workflow such as actions triggered by the environment and decisions taken by NEM.
+
+## Workflow description
+
+1. ONT discovered bottom-up
+2. If ONT serial number is not allowed or unknown (i.e it has NOT been provisioned by OSS), disable the ONT; generate an event to external OSS that an ONU has been discovered but not yet provisioned.
+3. When OSS provisions the ONT, re-enable it & program 802.1x flow - UNI port(s) will be UP
+4. Ensure that DHCP fails here (because subscriber/service-binding has not been provisioned by OSS yet)
+5. 802.1x EAPOL message happens from RG, and ONOS AAA app adds options and sends to radius server. Options are pulled from Sadis/NEM  - no subscriber information is required here
+6. If RG authentication fails, allow it to keep trying (in the future consider redirection to captive / self-help portal). DHCP should not succeed since RG authentication has failed
+7. If RG authentication succeeds, ONOS AAA app notifies via an event on the kafka bus that authentication has succeeded
+8. NEM can listen for the event, and then check to see if subscriber/service-binding has happened on that port from OSS - if not, then nothing to be done
+9. Must ensure that DHCP fails here even though RG has been authenticated (because subscriber/service-binding has not been provisioned by OSS yet)
+10. When OSS provisions the subscriber/service-binding on the UNI port and gives the C and S vlan info, then DHCP trap will be programmed on the port, and DHCP process can start
+11. If RG is disconnected from UNI port, force authentication again (even if subscriber/service-binding has been provisioned by OSS). Upon reconnection  to UNI port, RG must re-authenticate before DHCP/other-traffic can flow on the provisioned VLANs.
+12. DHCP L2 relay -> add option 82, learn public IP address, forward via dataplane to external DHCP server
+
+
+This schema summarizes the workflow, please note:
+
+- in `light blue` are environment events (wether they are triggered from hardware or from an operator)
+- in `yellow` are NEM configuration calls to ONOS or VOLTHA
+- in `green` are decisions
+- in `orange` event published on the kafka bus

+
+> NOTE: when we refer to `service chain` we are talking about the set of subscriber specific service instances that will trigger the `add_subscriber` call in ONOS-VOLTHA and provision the crossconnect in ONOS-FABRIC
