What network topologies are allowed? CoAP is agnostic to network topologies.
CoAP has been used on low power networks that have a central point of connectivity to the outside( sink). What is the span of the transport: LAN vs. WAN?
CoAP can be used within the LAN or across the WAN. CoAP clients and servers can be located in either the LAN or WAN.
CoAP implementations provide proxy 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, CoAP is an IP based communication protocol. 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.
