The openflowswitch hwft with hardware flow table reference design provides a set of board specific projects. An openflow switch is a software program or hardware device that forwards packets in a software defined networking environment openflow switches are either based on the openflow protocol or compatible with it. Enabling hardware exploration in software defined networking.

Openflow switch is designed to provide consistency in traffic management and engineering by making control function independent of the hardware it s intended to control. A company that wishes to offer a commercial openflow controller might start their project with one of the openflow controllers we list in section 13 8 add features to it.

Openflow switches are either based on the openflow protocol or compatible with it. Switch config no hardware profile openflow forward pdu optional removes the protocol data unit configuration. In a conventional switch packet forwarding the data plane and high level routing the control plane occur on the same device in software defined networking the data plane is. Ing of openflow switch performance.

We note that data plane forwarding performance is not in the scope of this paper. Specifically the focus of this paper is on analyzing control plane performance and flow table update rate in hardware openflow switches that support version 1 0 or 1 3 of this protocol. A hardware switch company wishing to convert a legacy switch into an openflow enabled switch may use the openflow switch code presented in section 13 7 as a starting point. It talks to openflow controllers over the network and to switch hardware or software through an ofproto provider explained further below.

Netdev the open vswitch library in lib netdev c that abstracts interacting with network devices that is ethernet interfaces. The difference lies in how flow rules are inserted and updated inside the switch s flow table. A standard switch can have static rules inserted into the switch or can be a learning switch where the.
