Abstract
An exemplary technique is provided for a scalable architecture for a network node that allows a very high switching capacity. The network node has a number of packet optical add drop multiplexers (POADMs), a number of dual line cards, respectively associated with the POADMs, and an optical switch matrix. Each POADM has an input and an output line interface and serves to selectively add and drop optical packets into and from packet timeslots of output and input wavelength-multiplexed optical signals transmitted and received at said output and input line interfaces, respectively. The dual line cards serve to electrically process and buffer packets to be added and dropped. The optical switch matrix configurably interconnects internal optical interfaces contained within the dual line cards on a packet by packet basis.
