Command broadcast
-
In this paper, we propose an energy-efficient command broadcast protocol based on the construction of a spanning tree which includes maximizing the number of leaf nodes, and the allocation of one sharable slot to each tree level. The sharable slot that allocates to tree level will be divided into multiple mini slots, and non-leaf nodes at the same level will compete for broadcasting; in this way, collision can be reduced.

For Annex J “BACnet/IP” communication, each device on a BACnet/IP network “speaks IP”, also using UDP transport. The BACnet/IP network may include more than one IP subnet and be spread out over more than one physical location. Devices may send di- rected messages as well as broadcast messages just as in a normal BACnet network. However, since IP does not support broadcasts, a special device is required—the BACnet Broadcast Management Device (BBMD).

Indicates the identity request message type sent from the local router to the network (assignment source point (ASP)) during the automatic TEI assignment procedure; this message is sent in a user interface (UI) command frame; the SAPI value for this message type is always 63 (indicating that it is a Layer 2 management procedure) but it is not displayed; the TEI value for this message type is 127 (indicating that it is a broadcast operation)

A DHCP client uses IP broadcasts to find the DHCP server. However, these broadcasts are not forwarded by routers, so in the case of the remote LAN, the workstations will not be able to locate the DHCP server. The router must be configured with the ip helper-address command to enable forwarding of these broadcasts, as unicast packets, to the specific server. Routing between the remote router and the campus router is done using a static route between the remote router and gateway router, and a default route between the gateway router and remote router....
