Embodiment 1

[0046] like figure 1 , as shown in 2 and 4, a high-concurrency tunnel system connecting cloud network and user intranet, including cloud network, public network, user intranet, cloud tunnel management module and address translation module, wherein:

[0047] The cloud network includes a cloud service facility, and the cloud service facility is provided with a cloud service logic module, and the cloud service logic module is used to reserve an address space CA in the cloud network, and the address space CA is used to accommodate concurrently accessed clients The sum of addresses in the internal network address segment;

[0048] Specifically, the address space CA is a public network address segment or a private network address segment, for example, CA=10.0.0.0 / 8.

[0049] The cloud tunnel management module is used to set up or remove the VPN (virtual private network) tunnel connecting the cloud network and the user's intranet in the public network;

[0050] The user intranet in...

Embodiment 2

[0062] The difference between this embodiment and Embodiment 1 is that, when the address translation module is located in the user intranet, the VPN tunnel transmits the address of the cloud-organized address segment allocated for the user, and the cloud network leads to the user In the direction of the intranet, the address translation module converts the address of the orchestration network segment into an address of the intranet; in the direction from the user intranet to the cloud network, the address translation module converts the address of the intranet into the address of the orchestration network segment.

[0063] In the process of this embodiment, the cloud tunnel management module will send a message of address translation parameter configuration to the springboard after the request for tunnel establishment is successful, and the cloud management module will convert the addresses of the orchestration network segment and the user equipment in the orchestration segment ...

Abstract

The invention discloses a high-concurrency tunnel system for connecting a cloud network and a user intranet, which comprises a cloud network, a public network, a user intranet, a cloud tunnel management module and an address conversion module, and is characterized in that the cloud network reserves an address space CA; the cloud tunnel management module is used for establishing or removing a VPN tunnel; when the cloud network accesses one user intranet i each time, an arrangement network segment Cai is allocated to the cloud network in a reserved address space CA of the cloud network to ensurethat any two user intranets are not overlapped; and the address conversion module is used for mutually converting the address conversion of the user intranet and the arrangement network segment address, and after the address conversion, the cloud network establishes connection with the user intranet through the VPN tunnel. The address is converted through the address conversion module to be matched with the VPN tunnel, cloud service facilities can concurrently access devices of different user intranets, the concurrency degree of cloud service users is improved, and meanwhile the cloud cost isreduced.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a high-concurrency tunnel system and method for connecting a cloud network and a user intranet. Background technique [0002] In many cases, the cloud service facilities on the cloud platform need to provide remote services to the devices inside the user network, which requires the establishment of a network connection from the cloud service facilities to the user's internal devices. Address translation (NAT) technology is generally adopted at the egress of the user network. The user intranet uses a dedicated network address segment, including 10.0.0.0 / 8, 172.16.0.0 / 12 and 192.168.0.0 / 16, while the cloud service facility is located in the public network , so the cloud facility cannot directly establish a network connection with the user's intranet device. [0003] In order to solve this network connection problem, a network springboard device needs to be installed inside the...
