Problems solved by technology
A small number of OPENFLOW-based switches are now available in the market, but in the announced OPENFLOW switches, the data channel solutions are all software processing or limited custom ASIC, with low processing performance or low degree of user customization. The form of programmable hardware fully supports the SDN network data plane, and the general network card does not have a good protection effect on the network card plug

The invention discloses an all-programmable SDN (Software Defined Network) high-speed network card. The all-programmable SDN high-speed network card comprises a network card body, a network card plug and a central controller, wherein the network card plug is fixedly arranged at one end of the network card body; a switch is arranged at one end, which is far away from the network card plug, of the network card body; an internal end of a connection block is connected with one end of an electric telescopic rod; the electric telescopic rod is electrically connected with the switch; the other end of the electric telescopic rod is connected with one end of a connecting rod; the other end of the connecting end is fixedly connected with an inner side of a protection cover; and the protection cover is movably connected to one end of the network card body in a sleeving way. Through adoption of the all-programmable SDN high-speed network card, the network card can be protected from being damaged by external force, and the network card plug is protected particularly, so that the service life of the network card can be prolonged. Moreover, through an SDN module and an all-programmable module, programmability of the network card can be realized on the aspects of hardware and software from bottom to top, and implementation of various network system nodes is ensured. The all-programmable SDN high-speed network card is economical and practicable.
Description
technical field [0001] The invention relates to the technical field of network cards, in particular to a fully programmable SDN high-speed network card. Background technique [0002] Software-Defined Networking (SDN) is currently a hotspot in network research. Its core is the separation of the data plane and the control plane. The control plane is abstracted and the upper-layer software is operated in a unified manner, which provides great flexibility for network design planning and management. Currently, OPENFLOW is the most widely used SDN protocol and has become the de facto standard of SDN. Through the OPENFLOW protocol, controllers other than network switching devices can program and manage behavior rules such as packet forwarding of network switching devices, making it possible for controllers to centrally control and manage the operation of switching devices in the entire network. A small number of OPENFLOW-based switches are now available in the market, but in the a...
