Everyone is familiar with the router. After all, it is the Internet era, and the network is everywhere. As a connecting device of the network, the router has long been familiar with and used by people. At present, routers have been widely used in various industries, and products of different grades have become the main force to realize the internal connection of various backbone networks, the interconnection between backbone networks and the interconnection between backbone networks and the Internet. But the routers that many people come into contact with are just ordinary home or enterprise routers. But in fact, there is another kind of router called Doka aggregation Router. I wonder if you all know about it. Today, the editor mainly wants to analyze that the friends who are interested in the Doka aggregation router can discuss it together.

1. The working principle of multi-card aggregation router:

Routing aggregation enables routing protocols to advertise many networks with one address, designed to reduce the size of routing tables in routers to save memory, and to shorten the time required for IP to analyze routing tables to find paths to remote networks.

Second, the aggregation algorithm:

A single signal source is used for transmission by reverse multiplexing multiple channels, and then reaggregated at the receiver. It includes and improves the IS algorithm, Smart VBR control and advanced FEC algorithm. Through Smart VBR (dynamic coding), the system dynamically manages the transmission rate of a preset delay, ensures that all transmission connections can be fully used, and finally obtains a reliable and stable high-quality network connection with subsecond delay. Compared with other algorithms, IS+ algorithm is faster and more stable, which can effectively improve the transmission efficiency and reduce the network delay.

It is worth mentioning that it also supports all public TCP and UDP protocols, and has better support for TVU Router, the VPN protocol for most enterprises to set up private networks. on top of the multiplexed transport protocol, after overlaying VPN, the transmission efficiency can still be maintained with high efficiency. VPN protocol includes L2TP and so on.

3. Preferred CVM:

The management system in the product cloud has the ability to identify intelligently and can select high-quality cluster servers according to the location of users. Thus, high-quality data links can be guaranteed anytime and anywhere, and data congestion can be avoided.

4. Sequential recovery of packets:

Multiplexing will split the data at the source side and send it through different wireless channels, and the server will recover it in an accurate order to ensure that the customer's data still arrives in the original order.

Fifth, multi-link priority setting:

For the core multiplexing, it can not only automatically detect the signal quality of each link, adjust the retransmission efficiency of the data packet, but also automatically select the pass signal with better signal to connect quickly and automatically to ensure the stability of the data connection.

The technical principles of aggregation routers from different manufacturers are not completely the same, but they are more or less the same. One technology that has to be mentioned is aggregation technology, which is the main technology of 4G multi-card aggregation router.

Taking Qianyuantong's multi-card aggregation router as an example, Qianyuantong successfully developed a "general-purpose large-flow aggregation communication module and system" and enabled multi-link graph transmission technology for the first time in China, which pioneered multi-link transmission architecture. it fills the gap of domestic weak network aggregation map transmission technology, which is not only an important part of the 5G industry chain, but also the core technology of basic communication guarantee.

By virtue of this technology company, it has successively won the Top 50 with the most potential for development in China and the Qingdao Science and Technology Progress Award.

The key projects of the conversion of new and old kinetic energy in Qingdao, the key projects of strategic emerging industries in Qingdao, the special new demonstration enterprises in Qingdao, the expert workstation in Qingdao, and the key projects of the cultivation plan of innovative enterprises in Shinan District.

And won the Ministry of Science and Technology Innovation and Entrepreneurship Competition National Outstanding Enterprise Award, the Ministry of Industry and Information Technology "Creator China" Innovation and Entrepreneurship Competition Internet Industry Competition and other honors.

It is one of the few manufacturers that can customize the aggregation transport card for customers in China. The adoption of bandwidth superposition technology can greatly improve the stability of data transmission. When a link or an operator has a poor signal quality, a large jitter, or even no signal, the route can be intelligently adjusted and packets can be forwarded normally from other links.

Multi-card aggregation routing is mostly used for on-site data acquisition / video acquisition network, on-site emergency command / rescue network, live broadcast / service network, on-site office / government network, etc., for the real-time high-bandwidth and high-stability network requirements on the spot, it is generally rarely used in families, so we are not common, and we know little about it, but the function of this router is really very powerful!
