Openflow Switch Hardware

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.

Openflow switch hardware. 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. Enabling hardware exploration in software defined networking. 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. We note that data plane forwarding performance is not in the scope of this paper.

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. The openflowswitch hwft with hardware flow table reference design provides a set of board specific projects. 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. It talks to openflow controllers over the network and to switch hardware or software through an ofproto provider explained further below.

A standard switch can have static rules inserted into the switch or can be a learning switch where the. Netdev the open vswitch library in lib netdev c that abstracts interacting with network devices that is ethernet interfaces. This combination of open source software and commodity hardware holds the potential for unprecedented efficiency and operational agility which fitted well in the world. 2 2 openflow switch openflow switches are like a standard hardware switch with a flow table performing packet lookup and forwarding.

Ing of openflow switch performance. The open vswitch library in ofproto that implements an openflow switch. Configuring global variable for cisco openflow agent logical switch for cisco nexus 3500 procedure command or action purpose.

An openflow switch is a software program or hardware device that forwards packets in a software defined networking sdn environment. 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.
