Mapping the VMAC to the nodes connection
URI:: e.g. „90d195d198bd“ to
„
wss://B1.THK:47809“
The VMAC is the virtual MAC address that is used under BACnet/SC to
address data requests and responses that are sent or requested by
the BACnet application. The virtual MAC address is then translated
into the actual target URI in the BACnet/SC data link using a table and
the data is then sent to the respective node via this URI.
The fact that a virtual address is used instead of the target URI or
target IP address is due to a restriction in the BACnet network layer,
which only allows addresses with a maximum length of 8 bytes.
But since BACnet/SC should also work for IPv6 (with 16 byte
addresses), virtual VMACs are used.
