MOST NetServices Layer I

MOST NetServices Layer I is the foundation of MOST NetServices providing the application with access to all the transportation mechanisms of MOST networks. Configuration files allow Layer I to be adapted to different application and platform requirements.

All INIC circuits have a majority of NetServices Layer integrated on-chip. A wrapper is required in MOST NetServices V2/V3 to interface to the Layer I on-chip. This wrapper is included in all grades and components.
