A generic interface for Open vSwitch
Dinh Thai Bui, Kahina Aberkane · 2016
In this paper, we describe a new generic interface to a software-defined switch allowing the controller to inform the switch of the existence of an external function. Through the same generic interface, the switch can call for the external function during its internal forwarding processes. Such innovating interface allows the network operator to add new functionalities to the switch, in the form of external functions, without having to upgrade the switch core forwarding processes. This should allow the operator for saving his/her OPEX After describing the new concept, we present the implementation of such a concept onto the open-source software-based Open vSwitch.
