Method, Apparatus and System for Communication Between OpenFlow Device and IP Network Device

摘要

Embodiments of the present disclosure provide a method, an apparatus, and a system for communication between an OpenFlow device and an IP network device. According to the embodiments of the present disclosure, an OpenFlow control message is used to carry payload information, a field value that is in a packet header and that is used to determine a protocol type, and identification information of the IP network device that are in a TCP/IP data packet of an IP network control plane protocol message in order to encapsulate the IP network control plane protocol message into the OpenFlow control message for transmission between an OFS and an OFC, such that communication between the OpenFlow device and the IP network device can be implemented, the OFC does not need to process a TCP/IP protocol stack twice, and extra overheads of the OFC are avoided.

主权项

1. A method implemented by an OpenFlow switch (OFS), the method comprising:
receiving, from an Internet Protocol (IP) device, an IP network control plane protocol message; converting the IP network control plane protocol message into an OpenFlow control message comprising information about a Transmission Control Protocol/IP (TCP/IP) data packet, wherein the information comprises payload information, a field value that is in a packet header and is used to determine a protocol type, and identification information of the IP network device; and sending the OpenFlow control message to an OpenFlow controller (OFC) for the OFC to enable, according to the protocol type, a corresponding switched network control plane protocol component to process the OpenFlow control message.
