WPAN Gateway and WPAN Range Extender Data Flow
Data Flow Paradigms
There are two potential data flow paradigms with the WPAN gateway and WPAN range extender devices:
• Serial DA device remote connectivity over CG-Mesh by transporting serial data in TCP/IP—this is
achieved by routing traffic between a WPAN gateway serial port attached DA device and an
application server through a Raw Socket connection
• IPv4 DA device remote connectivity over the IPv6-based CG-Mesh by using Mapping of Address
and Port using Translation (MAP-T)—this is achieved by routing traffic between a WPAN gateway
Ethernet port connected IPv4 DA device and an application server
Both traffic flows involves MAP-T enabling non-IPv6 traf
fic to be tran
sparently forwarded over
6LoWPAN, or the mesh network that is IPv6 only.
Figure 5-1 shows the deployment of the WPAN gateway and WPAN range extender devices and the role
of Raw Socket and M
AP-T.
