Abstract:
1. A method comprising: receiving data at an ingress line card of a communication node; separating the data into a first group and a second group; forwarding the first group to a first local interconnect module connected to the ingress line card; forwarding the second group to a second local interconnect module connected to the ingress line card; forwarding the first group and the second group to a third local interconnect module connected to the ingress line card; generating, at the third local interconnect module, a redundant version of the data by performing a mathematical operation on the first group and the second group; determining an egress line card based on a destination address included in the data; sending the first group from the first local interconnect module to the egress line card; sending the second group from the second local interconnect module to the egress line card; and sending the redundant version of the data from the third local interconnect module to the egress line card.
