Identify device as endpoint or switch with LLDP #3

Open sdhesika opened 7 years ago

Should we be using LLDP capacity type to identify whether attached device is an endpoint or a Network. For example: Switch (bridge - type =3) or Endpoint (Station - type = 8). This will help in multi-vendor switch environments. Email thread: https://basecamp.com/1791706/projects/12900329/messages/69380784

Thomas has added a user story for it in the following thread (user story copied below): https://basecamp.com/1791706/projects/12900329/messages/69380784#attachment_287904223

As a networked media operator, I need my SDN controller to be able to distinguish between endpoints and network devices in a predictable and consistent fashion in a multi-vendor environment, so that network topology can be coherently inferred by the SDN controller and communicated to NMOS services so that NMOS services can effectively authorize the streams that I desire.

One proposal is similar to the one above with a small change: If the network device can reliably do LLDP with Bridge type -3 and the endpoint can reliably do ARP (including receiver only endpoint), we have a solution to this issue. Please review and comment.

This is related to #32, and discussion in 'Full Stack' group. Perhaps with IS-06 as a northbound API, for true multi-vendor interoperability, a common southbound API (e.g. OpenFlow) needs to be discussed.
