一种基于SDN的ARP实现方法及装置制造方法及图纸

本发明专利技术实施例涉及数据通信技术领域，公开了一种基于SDN的ARP实现方法及装置，该方法为：控制器接收第一交换机发送的ARP请求，在确定本地不存在与ARP请求对应的ARP表项时，向第一交换机发送用于指示第一交换机将ARP请求泛洪的指令。这样，通过交换机之间的消息转发，可实现ARP请求在全网中广播，由于交换机之间转发消息比控制器向交换机发送packet‑out消息占用网络传输资源较少，因此，可大大减少ARP请求广播占用的网络传输资源，并提高ARP请求的广播效率，同时，由于减少了packet‑out消息的发送，降低了控制器的处理负荷，避免了控制器负荷较重，成为处理瓶颈的问题。

A method and device for implementing ARP based on SDN

The embodiment of the invention relates to the field of data communication technology, and discloses a ARP implementation method and device based on SDN. The method is that the controller receives the ARP request sent by the first switch, and sends the first switch to the first switch to indicate the ARP request when the ARP table item corresponding to the ARP request is determined locally. A flood command. In this way, by forwarding messages between switches, ARP requests can be broadcast in the whole network. Because the forwarding message between switches is less than the controller sends packet out messages to the switch, the network transmission resources of the ARP request broadcast can be greatly reduced and the broadcast of the ARP request can be improved. At the same time, because of reducing the transmission of packet out message, it reduces the processing load of the controller, avoids the heavy load of the controller, and becomes the problem of processing bottleneck.
