Each receiver would then do its own mixing. If multiple input signals pass through the same internal node at approximately the same time, that node can mix the signals. If the mixed signal is less than the sum of its constituents, this will reduce the total network traffic. It also reduces the bandwidth and the processing needed at the end nodes. Traditional data networks passively transport bits from one end system to another, i.e. the network is insensitive to the bits it carries and they are transferred between end systems without modification.
Active network carry methods that are executed at the nodes of the network.
The Beacon receives a SmartPacket and forwards it to the actual destination node based on the method stored in the SmartPacket. In this sense, the Beacon acts like a conventional router. However, as opposed to traditional routers, the Beacon itself need not be fixed. Active Nodes can be configured as Beacons as and when necessary. Example, receiving your fax message always on the fax machine nearest you.
