System and method for switching traffic through a network
View Patent ↗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.
1. A switching system coupling an external network to a wide area network, the system comprising:
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; and
wherein the interconnected matrix of switches comprises multiple stages of switches;
wherein each of the edge switches, core switches and interconnected matrix of switches is an independent switching element associated with a forwarding protocol configured to operate independently from one another;
wherein each of the edge switches, core switches and interconnected matrix of switches develops a forwarding table by exchanging route information with the other switches; and
wherein each of the interconnected matrix of switches is configured with its own broadcast local area network (LAN) facing the edge switches.
2. The system of claim 1 , wherein the interconnected matrix of switches comprises one or more of a full mesh, a partial mesh, a star, a ring, a n-cube, a toroid, a CLOS-like matrix, or an arbitrary mesh configuration.
3. The system of claim 1 , wherein the switches in the interconnected matrix forward communication traffic using one or more of an Ethernet protocol, an MPLS protocol, or a nonproprietary protocol.
4. The system of claim 1 , wherein the interconnected matrix of switches comprises a Local Area Network (LAN).
5. The system of claim 1 , wherein the external network comprises one of a metropolitan area network, a campus area network, an enterprise network or a personal area network.
6. The system of claim 1 , wherein the edge switches and the core switches forward communication traffic using one or more of an Ethernet protocol, an MPLS protocol, an Internet Protocol, or a nonproprietary protocol.
7. The system of claim 1 , wherein each of the edge switches and the core switches includes its own forwarding table.
8. The system of claim 1 , wherein the interconnected matrix of switches comprises ports facing the wide area network and ports facing the external network, and wherein each of the ports facing the wide area network are connected to a port on a core switch and each of the ports facing the external network are connected to a port on an edge switch.
9. The system of claim 1 , wherein the edge switches, the interconnected matrix of switches, and core switches are housed in separate chassis.
10. The system of claim 9 , wherein the plurality of edge switches comprises an edge switching stage, the interconnected matrix of switches comprises one or more middle switching stages, and the plurality of core switches comprises a core switching stage.
11. The system of claim 10 , wherein the independent switching elements are scaled according to the number of switches at each stage in the interconnected matrix of switches.
