Abstract
A method of transmitting data from a first node to a second node in a communication network includes receiving a signal; dividing the signal into data elements arranged in a first data stream comprising active and inactive data elements; analysing at least one characteristic of the signal to determine if the signal is stable; dropping at least one active data element from a plurality of data elements of the first data stream if it is determined that the portion of the signal included in the plurality of data elements is stable; inputting the data elements that are not dropped from the first data stream into a core stream; and transmitting the core stream from the first node to the second node.
