Openflow Switch Hardware

This combination of open source software and commodity hardware holds the potential for unprecedented efficiency and operational agility which fitted well in the world.

Openflow switch hardware. An openflow switch is a software program or hardware device that forwards packets in a software defined networking sdn environment. The difference lies in how flow rules are inserted and updated inside the switch s flow table. Cisco ios software c2960x software c2960x universalk9 m version 15 2 5 1 50 e test engineering estg weekly build synced to. 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.

Openflow switches are either based on the openflow protocol or compatible with it. 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. Ing of openflow switch performance.

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. We note that data plane forwarding performance is not in the scope of this paper. 2 2 openflow switch openflow switches are like a standard hardware switch with a flow table performing packet lookup and forwarding. The open vswitch library in ofproto that implements an openflow switch.

The openflowswitch hwft with hardware flow table reference design provides a set of board specific projects. Switch config no hardware profile openflow forward pdu optional removes the protocol data unit configuration. Enabling hardware exploration in software defined networking. 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.

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. Mode openflow mode openflow openflow switch 1 pipeline 1 controller ipv4 10 106 253 118 port 6653 security none. A standard switch can have static rules inserted into the switch or can be a learning switch where the.
