Abstract
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.
