ABSTRACT:
A method and system for maximization of the use of bandwidth capacity of an optical network when adding a data stream received from a switch to the optical network. In one embodiment, a data stream is added to the optical network. A data stream is received from a switch and grouped into a destination group. The destination group is then sent to the network. In another embodiment, a method for dropping a data stream received from an optical network to a switch is provided. A segment is received from the optical network. If the segment is a private segment, then it is demultiplexed into at least one data stream. The data stream from the private segment is then sent to the switch. In still another embodiment, a method for providing an interface between a switch and an optical network is provided. In this embodiment, a data stream is received from the switch. The data stream is grouped into a destination group and the destination group is sent to the optical network. Also in this embodiment, a private segment is received from the optical network. The private segment is demultiplexed into at least one data stream and the data stream or data streams are sent to the switch. In this embodiment, a public segment is also received. The public segment is demultiplexed into at least one data stream. If the data stream from the public segment is local, the local data stream is sent to the switch. If the data stream is non-local, the non-local data stream is returned to the optical network.
