Abstract
A controller for distributing logical control plane data to other controllers is described. The controller includes an interface for receiving user inputs to define logical datapath sets. The controller includes a translator for translating the user inputs to output logical control plane data. The logical control plane data is for subsequent translation into logical forwarding plane data by several other controllers. The controller includes a scheduler for (1) storing the output logical control plane data in a plurality of storage structures, each storage structure corresponding to one of the other controllers and (2) sending the output logical control plane data to the other controllers from the corresponding storage structure.
Claims14
A computer for distributing logical control plane data to controllers, the computer comprising:
- a set of processing units for processing instructions;
- a non-transitory machine readable medium storing sets of instructions for:
- receiving user inputs to define logical datapath sets;
- translating the user inputs to output logical control plane data, said logical control plane data for subsequent translation into logical forwarding plane data by a plurality of controllers;
- storing output logical control plane data for each controller that is a master controller of at least one logical datapath set;
- and
- sending in batch each controller's stored output logical control plane data to the controller.
A non-transitory machine readable medium storing a program which when executed by at least one processing unit distributes logical control plane data to controllers, the program comprising sets of instructions for:
- receiving user inputs to define logical datapath sets;
- translating the user inputs to output logical control plane data, said logical control plane data for subsequent translation into logical forwarding plane data by a plurality of controllers;
- storing output logical control plane data for each controller that is a master controller of at least one logical datapath set;
- and
- sending in batch each controller's stored output logical control plane data to the controller.
A method for distributing logical control plane data from a controller that receives user inputs that specify forwarding behaviors of a logical forwarding element implemented by a set of managed switching elements to a set of other controllers, the method comprising:
- translating the user inputs to output logical control plane data, said logical control plane data for subsequent translation into logical forwarding plane data by a plurality of other controllers;
- storing output logical control plane data for each controller that is a master controller of at least one logical datapath set;
- and
- sending in batch each controller's stored output logical control plane data to the controller.
