Inverse multiplexing to control data transfer

Telecom and internet have undergone significant changes due to the advent HFC, satellite and Wimax-networks. However, this has not rendered legacy copper based networks useless. In most countries competitive DSL solutions exist for the "last mile". An important characteristic/drawback of existing xDSL solutions is that it uses a dedicated pair of copper wires between subscriber and exchange (DSLAM). This precludes subscribers from using idle capacity of other neighboring xDSL subscribers. Thus valuable transmission capacity/bandwidth goes to waste/is lost. DSL bandwidth may now be sufficient for most subscribers but transmission capacity over DSL is nearing its physical limits.

Limited upgradeability of xDSL lines has been widely regarded to be a serious drawback of DSL technology. The invention however presents a cost-efficient way to further enhance transmission capacity over DSL networks. By creating individually accessible virtual high speed internet access the upgradeability issue is addressed. This is achieved by virtually bundling several neighboring xDSL lines by interconnecting the individual subscribers by means of a meshed (radio) network and inverse multiplexing up- and downstream traffic generated by the individual subscribers.


Because of the flexibility these systems and methods offer, they would be extremely useful to any company involved in managing network traffic or manufacturing network equipment.

Technical Summart

Inverse multiplexing of the individual data streams is performed through an algorithm embedded in a (distributed) software module in the local interconnection network. A reciprocal algorithm in the cloud recombines the split data streams into the original data stream generated by the individual subscriber. With downstream data a similar process is performed.
