Based on above-mentioned dual network framework, lower mask body introduction is based on the data transfer mode under the network architecture:
1, the downlink data that the second network is sent
The second server 400, for pushing second network to the network access equipment 200 with broadcast mode
In data, so that the client 100 obtains data from the network access equipment 200, wherein the broadcast mode is
Satellite broadcasting or terrestrial broadcasting or optical fibre broadcast.
For all the elements in the second network (such as U-CDN network), it is stored in each second server 400
In resources bank, second server 400 is understood by these Web content broadcast distributions in resources bank into network access equipment 200,
It is i.e. that the Web content difference in the second network is labelled, and by the abstract of each label and corresponding network content and right
The Web content answered is pushed to network access equipment 200 in the form broadcasted, and 400 jumps of need 1 of second server can be by content
It is pushed to network access equipment 200.Second network is low jump network, and satellite, similar radiated television can be used or have
The modes such as the terrestrial broadcasting of line television network or optical fibre broadcast based on light splitting, directly distribute data with broadcast mode, exist in this way
All users in the broadcast coverages such as satellite can directly obtain from the local i.e. network access equipment 200 (can be simultaneously
Row obtains) Web content in second network, avoid the channel competition that traditional network can not be avoided.In addition, U-CDN net
The trunk of network is an autonomous controllable hub-and-spoke configuration, and default only has down going channel to pass through central nodule without direct data feedback channel
Point control, neither influence performance, and arbitrarily network attack path can be blocked well.
For the data communication mode of U-CDN network, data downstream uses broadcast transmission methods, second server 400
When with broadcast mode to 200 propelling data of network access equipment, satellite or satellite-base station or satellite-specifically can be used
The traffic channels data such as hovering aircraft, even quantum network, data pass through above-mentioned communication channel by second server 400
