Patent number: 10084613Abstract: A self adapting driver for controlling datapath hardware elements uses a generic driver and a configuration library to create a set of data structures and methods to map information provided by applications to physical tables. A set of virtual tables is implemented as an interface between the applications and the generic driver. The generic driver uses the configuration library to determine a mapping from the virtual tables to the physical tables. A virtual table schema definition is parsed to create the configuration library, such that changes to the physical infrastructure may be implemented as changes to the virtual table schema definition without adjusting the driver code. Thus automatically generated creation of generic packet forwarding drivers is able to be implemented through the use of a configuration language that defines the meaning of the information stored in the virtual tables.Type: GrantFiled: September 27, 2012Date of Patent: September 25, 2018Assignee: Extreme Networks, Inc.Inventor: Hamid Assarpour
