Problems solved by technology

However, since different PUC platforms may allocate the same virtual IP address for themselves, related technologies will cause conflicts in the virtual IP addresses of PUC platforms, which will cause the multi-level and multi-domain monitoring system of the public security national standard protocol to fail to interconnect.

Embodiment Construction

[0041] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0042] see figure 1 , figure 1 It is a network diagram showing a multi-level and multi-domain monitoring system of the public security national standard protocol.

[0043] in such as figure 1 In the monitoring system shown, the server of the provincial department platform is located in the upper-level domain, and the server of the city bureau platform is located in the lower-level domain. Th...

Abstract

The invention relates to a virtual IP address allocation method and device. The method comprises the steps that a tunnel building request message is sent to a VPN server, wherein the tunnel building request message comprises a user name and a user password; an advice message which is used for indicating that a VPN tunnel is agreed to be built and sent by the VPN server according to the situation that verification of the user name and the user password is passed is received; after the advice message is received, the virtual IP address used for building the VPN tunnel is allocated to the VPN server from a preset address pool. Due to the fact that a VPN client is used for allocating corresponding virtual IP addresses for multiple VPN servers connected with the VPN client, the problem that in related technologies, due to the fact that the multiple VPN servers allocate the same virtual IP address for the VPN servers themselves, interconnection of monitoring systems cannot occur can be solved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for allocating virtual IP addresses. Background technique [0002] With the continuous development of standardized and easily expandable network technology and IP technology, intelligent monitoring technology based on IP and network has developed rapidly, and IP monitoring has become the mainstream of current monitoring. In the multi-level and multi-domain monitoring network of the public security national standard protocol, each city bureau platform and the provincial department platform are interconnected, but because the provincial department platform is isolated from several city bureau platforms through NAT (Network Address Translation, Network Address Translation) , and the provincial government platform is generally inside the NAT. Therefore, when the municipal bureau platform and the provincial government platform perform data interaction, VPN (...
