This document specifies the technical requirements for the lean application layer for MOST, a synchronous time-division-multiplexing network.

The lean application layer includes a specification of the services available to control the configuration and behaviour of the network management.

The lean application layer covers the definition of:

  1. node kinds,

  2. node addressing,

  3. data transport,

  4. network configuration,

  5. lean network services interface,

  6. network management, including connection management,

  7. diagnosis, and

  8. timing definitions.
