* The central entity of OFP is the Device Context, which encapsulate the logical state of a switch

* which is enforced by keeping a cap on the number of outstanding requests a particular Request
* Context can have at any point in time. Should this quota be exceeded, any further attempt to make
* a request to the switch will fail immediately, with proper error indication.
