What network topologies are allowed ?
DDS is agnostic to network topologies . All possible network topologies can be used with DDS . What is the span of the transport : LAN vs . WAN ?
A DDS data space is agnostic to the network constraints , and can therefore span both the LAN and the WAN . DDS implementations allow application components to be located anywhere — on the LAN or across the WAN . DDS 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 , DDS can support multiple independent and isolated communication paths between the same network endpoints . DDS accomplishes this by providing a PARTITION QoS policy , which allows communication between DDS endpoints tagged with the same partition label .
