Communication method, related buffering element and line termination element

The present invention relates to a communication method, and related buffering and line termination elements to be used in a communication network. The communication network includes a buffering element, a line termination element and several network termination elements. The buffering element is coupled to the line termination element, and the line termination element is coupled to each of the network termination elements over a shared medium. The buffering element and the line termination element interact in such a way that the line termination element adjusts a cell input/output rate of the buffering element to bandwidth related conditions of the network termination elements, or vice versa.
