Abstract:
1. A system for transporting data from a plurality of ingress lines to a plurality of egress lines comprising: a data switching matrix having a plurality of ingress ports and a plurality of egress ports, wherein for each of the ingress ports, the data switching matrix is configured to transport data from each the ingress port to one of the plurality of egress ports; a plurality of ingress edge units, each of which is coupled to one of the plurality of ingress ports of the data switching matrix, wherein each of the plurality of ingress edge units is configured to receive a data from a corresponding one or more of a plurality of ingress lines; a plurality of egress edge units, each of which is coupled to one of the plurality of egress ports of the data switching matrix, wherein each of the plurality of egress edge units is configured to transmit data received from the data switching matrix to one or more of a plurality of egress lines; wherein each of the plurality of ingress edge units is configured to examine data received via the corresponding ingress lines and to identify portions of the data corresponding to each of the egress edge units, wherein portions of the data corresponding to each of the egress edge units is stored in a corresponding buffer, and wherein data in each buffer is transmitted to the corresponding egress edge unit via the data switching matrix in a predetermined time slot, wherein the ingress edge unit comprises: wherein the ingress edge unit is configured to:
