Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] For IP (Internet Protocol, Internet Interconnection Protocol) network, in theory, as long as the IP addresses of the communication parties remain unchanged, the network connection between the two parties will not be disconnected, so as long as the following two points are fulfilled, the network can be switched seamlessly. 1 , The IP address of the IP message transmitted to the network peer (such as a file server in the network) remains unchanged after the net...

Abstract

The embedment of the invention discloses a network seamless handover device, a network seamless handover system and a computer terminal. The device is used in a terminal which is connected to an enterprise gateway through a virtual private network, and comprises a handover control proxy module which is positioned between a transmission control protocol (TCP) / internet protocol (IP) stack and a network card and is used for shielding the plug and play (PNP) event of the network card for the TCP / IP stack and reconnecting to the enterprise gateway through the virtual private network after the network handover is accomplished successfully. The technical scheme provided by the invention can realize the seamless handover of the network on the basis of not changing the conventional network architecture.

Description

technical field [0001] The invention mainly relates to the field of network switching, in particular to a network seamless switching device, system and computer terminal. Background technique [0002] With the development of communication technology, it has become the direction of development to realize the integration of communication services and communication networks through various common protocols. The purpose is to make communication more convenient for users. Handover technology is a technology required for communication networks to provide services, which enables terminals to obtain online connections and services at any time and anywhere. At present, there are more and more network methods, and the mobility of users is also increasing. It is often necessary to switch between different networks. When switching between networks, it often leads to complete disconnection of network applications, thereby affecting user experience. Therefore, there are more and more tec...
