Embodiment 1

[0028] A frame diagram of a DDS-based cross-wide domain dual roaming data transmission method is like image 3 Indicated. The framework is composed of four modules, namely the user registration module, the network data exchange module, the GUID and IP mapping module, and the data transfer module. The data interaction between each module is seen Figure 4 . User Registration Module When you register, first provide the name of the application, appname, and then generate the AppName to generate a GUID through the Hash function, and finally return the GUID to the user.

[0029] Network Data Exchange Module first creates DDS entities in different local area networks. After the entity is created, the gateway in which the entity is located will record information such as GUID, AppName, and IP addresses. When an entity is online, the data of the entity itself is sent to the subnet gateway in which the entity is located. After receiving the data, the gateway will not only record this data, b...

Abstract

The invention discloses a DDS-based cross-wide-area-network dual-roaming data transmission method and system and a storage medium, and the method comprises the following steps: 1, generating a unique identifier GUID for identifying a transmitting and receiving entity by using an application name recorded as AppName; 2, exchanging data such as GUID, AppName, IP address and the like between the gateways; 3, mapping a GUID and an IP address; and 4, addressing the receiving and transmitting entities based on the three steps to complete data transmission. According to the method, the concept of data receiving and transmitting entity identifiers is introduced, and GUIDs, application names and IP addresses are managed and converted. Through the operation, the DDS system supports cross-wide area network, roaming of the data transceiver is supported in the wide area network environment, and effective support is provided for cross-wide area network data roaming transmission. A user does not need to pay attention to network composition and topology, and data transmission is carried out through a specified destination opposite terminal; and the application can roam among the subnets, so that the flexibility of the application is enhanced.

Description

Technical field [0001] The present invention relates to the field of computer networks, and more particularly to a DDS-based cross-domain dual roaming data transmission method, system, and storage medium. Background technique [0002] Wi-Fi is easier to deploy relative to wired networks, which is more flexible and has been widely used in various research fields. The market growth rate of wireless network is getting faster and faster, which has become an indispensable part of people's lives. Roaming is one of the important key services in network transfers, which supports mobile users to access to the network anywhere in order to perform data transmission, so that the data is transmitted unusually restrictions. With the support of roaming services, mobile users can enjoy the convenience of mobile communication and can get massive information in the Internet. Roaming services greatly enhance the network experience of mobile users to meet the needs of mobile users. [0003] At prese...
