Can Lianpu multi-WAN port routers set overlay bandwidth?
TP-link Lianpu is one of the world's leading communication suppliers, so do you know that Lianpu multi-WAN port routers can set overlay bandwidth? Information about overlay bandwidth is for your reference.
The reason why Lianpu router has multiple WAN ports
There are three main purposes of connecting multiple broadband routers:
Increased bandwidth: The Internet host can access the Internet through any broadband, which is equivalent to a higher-speed bandwidth from the application point of view.
Redundant backup: If one of the broadband fails, you can use the other broadband to access the Internet to ensure that the network is smooth and uninterrupted.
ISP route selection: the so-called "access to China Unicom via China Unicom, access to Telecom via Telecom", so that the access purpose takes the correct path.
Can the bandwidth of multiple broadbands be superimposed?
A: Consider two aspects:
[1] For the entire local area network , the number of egress bandwidth is increased, which is equivalent to an increase in the total bandwidth, which can have a superimposed effect.
[2] For a specific host, whether multiple broadbands can be superimposed is related to the application of the host. Let's answer with one example:
The interface router of the network where host A is located pulls two broadbands, as follows:
Interface Broadband Type Downstream Bandwidth Upstream Bandwidth
WAN1ADSL4M512K
WAN2 fiber 20M20M
Note: M here is Mbps, 1Byte=8bit, such as 512Kbps=64KBps.
What is the Internet bandwidth of intranet host A without considering the bandwidth occupied by other hosts?
Upload:
The maximum upload speed of the host to a server on the Internet is 64KBps (512Kbps) or 2.5MBps (20Mbps). The reason is that when uploading to the same server, only one WAN port can be used. For example, QQ uploads email attachments, Baidu network disk uploads, etc.
If it is a multi-link upload, the upload speed can be superimposed.
download
There are two kinds of downloads, multi-link download and single-link download:
Multi-link download: If you start downloading on Thunder, and the number of resources is greater than 1, it means multi-link. At this time, the bandwidth can reach 24M, that is, the WAN port bandwidth can be superimposed. Common applications such as P2P download, P2P video, etc.
Single-link download: For example, right-click >> Save Target As to save a file locally. This kind of download is a point-to-point download and can only go through a fixed WAN port, so the download rate is 500KBps (4Mbps) or 2.5MBps (20Mbps), which cannot be superimposed. Common applications such as downloading data from a company's website.

Generally, it is a single link, and you can only experience the maximum bandwidth of a WAN port.
Frequently Asked Questions about Setting Up Overlay Broadband
1. If multiple single link downloads are enabled, can they be superimposed?
Under normal circumstances, superposition can be achieved, and multiple single links are equivalent to multiple links. However, the target server is required to be different, otherwise it is still a point-to-point transmission.
2. Does Xunlei download have to be multi-links?
Not necessarily, to judge whether it is a multi-link, you need to see the number of resources available on Thunder, if it is 1, it means a single link.
3. Can multi-link downloads be superimposed?
Under normal circumstances, multi-link downloads can be superimposed. However, if all links are connected to the Internet through a WAN port, they cannot be superimposed.
