  • System and method for switching traffic through a network
    Patent number: 9426092
    Abstract: Embodiments of the present invention generally relate to network communications. More specifically, embodiments relate to a system and method for switching data through a network. An embodiment of a switching system communicatively couples an external network to a wide area network. The system includes a plurality of edge switches communicatively coupled to the external network, a plurality of core switches communicatively coupled to the wide area network, and an interconnected matrix of switches communicatively coupled to the core switches and the edge switches and configured to forward communication traffic between the edge switches and the core switches.

  • Systems and methods for network routing in a multiple backbone network architecture
    Patent number: 8995451
    Abstract: Embodiments of a network architecture include a backbone node having a plurality of independent routers or switches connected in a matrix, wherein the matrix includes a plurality of stages of routers or switches, to form a node having a node switching capacity that is greater than the node switching capacity of the individual routers or switches. A method includes assigning one of a plurality of backbone networks to a destination network address, associating a next hop loopback address with the destination network address, and advertising the destination network address in combination with the next hop loopback address through the selected backbone network address.
