Patent number: 9559948Abstract: A network switching device includes a macroflow sub-plane that performs packet-based routing in the network switching device and a microflow routing module that performs flow-based routing in the network switching device. The microflow routing module is separable from the network switching device and operates to provide a data packet via a software defined network agent to an SDN controller. The data packet is associated with a first unknown flow on the network switching device. The microflow routing module further operates to receive via the SDN agent a flow-based routing rule from the SDN controller and route the data packet based upon the flow-based routing rule.Type: GrantFiled: August 28, 2012Date of Patent: January 31, 2017Assignee: DELL PRODUCTS, LPInventors: Rajesh Narayanan, Saikrishna Kotha, Robert L.

If the frame type is a log in frame, then the frame is forwarded to the second device and another access control entry is added to the access control list. The second access control entry causes the network device to permit data frames to be forwarded from the first device to the second device. If not, then the frame is dropped based upon the first access control entry.Type: GrantFiled: May 27, 2011Date of Patent: April 9, 2013Assignee: Dell Products, LPInventors: Gaurav Chawla, Saikrishna Kotha
