M2M world of connected services
• The current marketplace is extremely fragmented, which has increased the R&D cost in each specific domain.
• Current M2M silo model is not an efficient way to communicate, it is a barrier to further development.
• Many vertical M2M solutions have been designed independently and separately for
different applications, which impedes large-scale M2M deployment.
M2M market fragmentation

143 organizations around the world are involved in M2M standardization according to the Global Standards Collaboration M2MTask Force.

Standards landscape for M2M
Standards for vertical Industries applications Target: enable interoperable, cost-efficient Solutions
Standards for M2M Service capabilities: Target: end-to end enablement across servers, gateways, devices with standardized service interfaces.

Standards for M2M service capabilities
M2M network 5
Smart M2M standard (ETSI M2M)
Provide a horizontal M2M service platform with a generic set of service capabilities to enable M2M interoperability in terms of communication and data.
Define a Service Capability Layer (SCL) on top of connectivity layers:
SCL deployed in network server, gateways and devices.
SCL enables discovery, registration, authentication, data-transfer using containers, publish/subscribe, groups, access rights, security, etc.
Interface with existing technologies: Multiple communication
protocol binding. Re-use existing remote
device management. Interwork with vendor-
specific and legacy devices.
Facilitate innovation across industries by exposing data and providing services.

• OM2M provides a Service Capability Layer (SCL) including a set of common services for M2M interoperability.
• A SCL can be deployed on the Network domain, or on the Device and Gateway domain.
OM2M primitive procedures and resources
SCL resource tree structure 10
OM2M implements a RESTful API. All M2M communications are performed
based on simple primitive procedures.
• Each SCL data model is structured using a standardized resource tree.
• The resources can be simply triggered using basic CRUD requests.

OM2M building blocks
13
OM2M is a java platform running on top of an OSGi Equinox runtime which make it highly extensible via plugins.
Each SCL includes required plugins and is build as an Eclipse product using maven and Tycho.
