What network topologies are allowed? oneM2M service layer is agnostic to network topologies. What is the span of the transport: LAN vs. WAN?
oneM2M service layer can be used within the LAN or across the WAN. CSEs and application can be located in either the LAN or WAN. The root CSE of the hierarchical tree is usually located within the M2M service providers WAN environment.
oneM2M service layer implementations provide mechanisms to deal with firewalls and other restrictions encountered when going across the WAN.
Can the transport support multiple independent and isolated communication paths between the same network endpoints?
Yes, since the oneM2M service layer runs on IP based communication protocols. As such it can support multiple independent and isolated communication paths between the same network endpoints using the underlying IP network ' s mechanisms for path redundancy and isolation.
