When the ISP network to which the IP address returned by the DNS server domain name resolution system belongs is not the ISP network to which the client device belongs, such as figure 1 As shown in , the client device uses the telecommunications network, but uses the IP address provided by China Mobile to access the TS transcoding server. This cross-operator network method will cause a large amount of data loss and a large delay during transmission. The image quality is degraded, and when it is more severe, the live screen is blurred and video data is lost, resulting in poor user experience

Embodiment Construction
[0021] In order to solve the above problems, the present invention provides a single domain name and multiple IP domain name resolution method and system to realize that the IP addresses corresponding to the outgoing interface of the client and the TS transcoding server belong to the same ISP network, thereby ensuring that the monitoring images obtained by the client quality.
[0022] See figure 2 , the present invention provides a domain name resolution method for multiple IPs of a single domain name, said method comprising the steps of:
[0023] 101. Among the multiple IP addresses corresponding to the TS transcoding server domain name resolved by the DNS server, the client device selects the first IP address according to preset rules (randomly or in a certain order) as the registration request report to the TS transcoding server. The destination IP address of the message, and the registration request message carries the ISP information to which the client device belongs; ...

The present invention provides a single domain name and multiple IP domain name resolution method and system. The method is as follows: a client device selects the first IP address and sends a registration request message to the transcoding server and carries the ISP information to which the client device belongs; The code server judges whether the first IP address is the same as the ISP to which the client device belongs, if so, generates a routing table entry, and its outgoing interface is the first interface; The same second IP address of the ISP and write the registration response message; the client device judges whether the second IP address is in the cache, and if so, sends a keep-alive message to the transcoding server with the second IP address and carries the update tag; if The transcoding server parses out that the keep-alive message carries the update tag, and then generates a routing entry, where the outbound interface is the second interface. The invention can ensure the image quality of the monitoring video and improve the utilization rate of the ISP network bandwidth.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a domain name resolution method and system for a single domain name and multiple IPs. Background technique [0002] With the rapid development of IP network video surveillance technology and mobile Internet technology, remote video surveillance has gradually become a hot spot in the surveillance industry, and the convenient and fast mobile remote terminal intelligent security is more popular among people. In order to realize the remote intelligent security function of the mobile terminal, mobile monitoring client software is usually installed on the mobile terminal. Since the code stream format of the monitoring data usually matches the video monitoring terminal, it is relatively difficult for ordinary client devices to read the data. Therefore, a TS transcoding server will be added between the client device and the monitoring device so that the client device can ...
