A LINUX soft router that supports hybrid multi-line access

There are many ways to implement broadband Internet access now, for ADSL. Most of them enable ADSL Modem's routing function to achieve broadband sharing. For some community width, it is generally to use a special computer as a server or a broadband router, but purchasing a broadband router alone is also a considerable expense. For Internet cafes, whether it is using ADSL dedicated lines or optical brazing dedicated lines, the choice of routers is directly related to the operational efficiency of Internet cafes, so it is particularly important. There are only two types of routers used in Internet cafes, one is commercialized hard routes; the other is homemade soft routes. The practice of many Internet cafes has proved that soft routing is far better than hard routing in terms of performance or cost-effectiveness. There are many articles on homemade broadband routers on the Internet now. The more common and simple configuration is BBIagent, but this thing is no longer free now. The software registration fee for each router is US$36. There are many similar soft routers, such as Yipanxiu, Network Shenniu, FD Linux, LRP (Linux Router Project Linux Router Project), FLi4L, Freecso, coyote Linux, Smoothwall, etc. These things have a common feature, they are all based on Linux, and some can run on a floppy disk, and their performance is also relatively excellent. However, all these soft routers can only support the access of a single broadband line. Faced with the access needs of hybrid multi-lines, they can only sigh.

Below is a Linux soft router that supports hybrid multi-line access

Do Internet cafes need to support Linux soft routing that supports hybrid multi-line access? Due to the objective situation of broadband access, many Internet cafes have multiple different lines, such as: telecom fiber, network fiber, ADSL dedicated line, dynamic ADSL line, etc. How to make full use of bandwidth resources, save Internet access costs, and improve Internet access efficiency is a problem that Internet cafe operators deserve attention in the face of increasingly fierce market competition.

This Linux soft router that supports hybrid multi-line access has two main functions:
1. It is to realize hybrid multi-line bundling access gateways, such as fiber and ADSL bundling, the benefits are:
(1). Bandwidth accumulation, the bundled bandwidth is the sum of the bandwidth accumulation of all lines;
(2). The lines are divided into each other. If a line fails, the Internet cafe will not be disconnected and there is no need to switch manually;
(3). Save Internet access costs, such as: after 4M fiber + 2 2M ADSL bundled and connected, the effect of 8M fiber can be achieved or close to that of 8M fiber, and the cost is much lower than the cost of 8M fiber;
(4). Automatic flow and load balancing;
(5). Avoid the inconvenience of managing multiple gateways. There is only one gateway in the Internet cafe, which avoids the hassle of managing multiple gateways, and there is no need to purchase new routes after adding lines.

2. It is an intelligent gateway that implements policy routing functions
For example: A certain Internet cafe has two optical fibers, which belong to China Netcom and China Telecom respectively. If some game servers are located on Netcom's dry network, it is better to use Netcom's fiber access; if they are located on Telecom's dry network, it is better to use Telecom's fiber access. On this Linux soft router that supports hybrid multi-line access, connects to Netcom and Telecom optical fibers at the same time. Through the definition and setting of policy routing, accessing Netcom websites, you can directly access Netcom optical fibers; when accessing Telecom websites, you can directly connect to Telecom optical fibers.

Other functions introduction
1. Bandwidth management function
In Internet cafes, the main things that use the Internet are browsing web pages, downloading files, various chat services, online games, and watching movies online. Real-time network applications are online games and various chat services that are the key business of Internet cafes. This Linux soft router can set different bandwidth restrictions and priority levels according to different IP addresses and service categories to ensure bandwidth traffic of important user services.
Moreover, this Linux soft router has made special processing for online games and has specially optimized the online game port, so the speed of playing games is faster than that of routers and proxy servers.
2. High-performance firewall
It can prevent external attacks and malicious corruption from internal opponents, such as malicious damage from competitors. This Linux soft router provides a packet filtering firewall function based on status monitoring. Through a simple management interface, filtering rules can be set conveniently and flexibly. The packet filtering function acts in the network layer and the transport layer. It can monitor data packets based on the packet header source address, destination address and port number, protocol type, flag bit and other information to determine whether the data packet is allowed to pass. Only packets that meet the filtering logic are forwarded to the corresponding destination exit, and the remaining packets are discarded from the data stream.
3. Antivirus gateway
Traditional routers and proxy servers only provide Internet access functions. For viruses in LANs, they cannot intercept and isolate functions. This Linux soft router has a professional anti-virus gateway. As long as a virus machine appears in the LAN, the system will automatically intercept and isolate it, so that the entire LAN cafe will not be spread wildly, thus saving a lot of manpower and material resources for the Internet cafe.
