Technical analysis of qianyuantong multi card aggregation router

Before introducing the multi card aggregation router , Let's look at an example first ：
If there is now 1000 A car needs to be moved from A City bound B City , Need to arrive on time B Assemble at the city site , Suppose the current road is designed as a single lane , It doesn't matter if you take the expressway, provincial highway, national highway or something , There will be traffic jams , It is impossible to arrive on time . To arrive on time B Gather at the designated place of the city , Only single lane can be changed into multi lane . Even if one or both of the lanes are blocked , Other lanes can still run normally , In this way, the traffic volume of each lane can be appropriately allocated , More express lanes are allocated , Less traffic lanes are allocated , This can ensure that all vehicles can run smoothly in the whole traffic process , Can safely reach the destination ;
Qianyuantong's multi card aggregation router probably transmits data according to this idea , Avoid delay caused by poor packet transmission due to single line transmission congestion . Transmission over multiple links , According to the network transmission conditions of different links at that time, packet transmission is carried out and then aggregated on the server , It can transmit data better and faster .

 

  
One 、 Function overview of the device
Qianyuantong multi card aggregation router is an internet router that supports multi-channel aggregation ,1 road WAN Extranet input is used for aggregation ,4 road LAN Output to computer or network equipment , It can also provide 2.4G and 5.8G Wireless networks in the frequency band , It can supply network for more devices , To meet more needs of users ;
Weak network aggregation router has 3 individual 4G Communication module and 3 individual 5G Communication module , Support to mix and insert different operators at the same time SIM card , Aggregate through ECS 4 The bandwidth of the Internet link , You can also use a single card without using ECS , But you can only run single card traffic , It improves the uplink and downlink network bandwidth in the mobile environment , Reduce the signal blind area of mobile network , Improve network availability .

 
Two 、 Problems that equipment can solve
1. Network uncertainty 、 When not ideal , Still provide stable communication guarantee .
2. Smooth large-scale data transmission . such as ： Solve the problem of jamming during live video broadcast 、 Unclear phenomenon . Let the live broadcast scene be free from network constraints .
The real-time video playback rate of HD live broadcast should reach 400KB/s～500KB/s, At present, the transmission rate of most wired broadband networks in many events is difficult to reach this standard , The cost of setting up special lines is huge and troublesome . although 4G、5G The network can meet this technical standard , But on many occasions, due to the flow of people 、 Distribution of base stations 、 Dense buildings block 、 bring 4G、5G The signal fluctuates greatly . A single card cannot guarantee the stability of live video data transmission . At present, whether it is TV stations or business broadcast technology service practitioners 、 It is generally accepted that multi card aggregation can overcome the fluctuation of the network , Ensure that the live broadcast is clear, smooth and stable .
3、 ... and 、 Usage scenarios for equipment matching
1. Video instant transmission and other scenarios （ Emergency communication guarantee 、 Vehicle communication 、 telemedicine ）
2. Use big data transmission network in weak network environment
3. High speed railway and other high-speed operating environment
