A packet forwarding network may include spine and leaf switches that forward network traffic between end hosts that are coupled to the packet forwarding network. A controller may control the switches in the forwarding network to implement desired forwarding paths. The packet forwarding network may additionally include access switches that are directly connected to edge switches to form access switch groups. The access switches may also be controlled by the controller. End hosts may be coupled to access switches as well as leaf switches to extend the reach of the packet forwarding network. Additionally, the access switches may include access-leaf switches and access-edge switches to improve network routing capabilities and network flexibility.
A method of operating a controller to control a network having a leaf switch implemented on a network rack, a spine switch coupled to the leaf switch, and an access switch coupled to the leaf switch the method comprising:
A method of using a controller that controls switches in a packet forwarding network including an access switch group, a core switch, and an edge switch coupled between the access switch group and the core switch the method comprising:
A method of operating computing equipment to control switches in a network having end hosts that are coupled to ports of the switches, the method comprising:
