Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0044] An SDN-based IPv4 / IPv6 conversion system shown in an exemplary embodiment of the present invention includes: an IPv6 / IPv4 dual-stack client, an IVI server, and an SDN switch, wherein:

[0045] The IPv6 / IPv4 dual-stack client is configured with an IPv6 address and an IPv4 address;

[0046] The IVI server is used to convert the IPv4 data packet received from the SDN switch into an IPv6 data packet and return it to the SDN switch;

[0047] The SDN switch is used to receive IPv4 packets from the IPv6 / IPv4 dual-stack client, and the SDN switch is used to judge whether the IVI server is running normally, and when the IVI server is running normally, the SDN will The IPv4 data packet received from the IPv6 / IPv4 dual-stack...

Abstract

The invention provides an IPv4 / IPv6 (Internet Protocol version 4 / Internet Protocol version 6) conversion system and method based on an SDN (Software Defined Network). In the system, an IVI (Interchangeable Virtual Instrument) server is used for converting an IPv4 data packet received from an SDN switchboard into an IPv6 data packet and then returning the IPv6 data packet back to the SDN switchboard; the SDN switchboard is used for receiving the IPv4 data packet from a client and the SDN switchboard is used for judging whether the IVI server is normally operated or not; if the IVI server is operated normally, the SDN is used for transmitting the IPv4 data packet received from an IPv4 / IPv6 dual-stack client to the IVI server and sending out the IPv6 data packet returned back by the IVI server through an IPv6 route; when the IVI server is operated abnormally, the SDN switchboard is used for transmitting the IPv4 data packet received from the client through a reserved IPv4 route.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to an SDN-based IPv4 / IPv6 conversion system and method. Background technique [0002] Today, the Internet has become an important source of knowledge, and individuals, schools, and businesses have access to the Internet in various ways. The connection between the campus network and the Internet does provide great convenience to teachers, students and staff, but it also brings severe challenges to management. In the campus network, the following issues need to be considered: [0003] 1. Sustainable development of the Internet [0004] Operating a network requires not only initial investment in software and hardware, but also continuous operating expenses. If you rely entirely on the school's funds to maintain network operations, it may bring a lot of financial burden to the school. This needs to give full play to the businessability of the network and realize a healthy ...
