A Linux soft route supporting hybrid multi-line access

There are many ways to achieve broadband Internet access, for ADSL. Most of them enable the ADSL modem routing function to achieve broadband sharing. For some residential broadband, a dedicated computer is generally used as a server or a Broadband Router, however, purchasing a Broadband Router separately is not a small expense. For Internet cafes, the choice of routers is directly related to the operation efficiency of Internet cafes, whether it is through the ADSL leased line or the optical brazing leased line. Therefore, there are two types of routers available for Internet cafes, one is commercialized hard routing, and the other is self-made soft routing. The practice of many Internet cafes proves that soft routes are far better than hard routes in terms of performance and cost effectiveness. There are many self-made software broadband routers on the Internet Article Bbiagent is a common and simple configuration item, but this item is not free now. The software registration fee for each router is USD 36. There are many similar soft routes, such as the disk show, network shiniu, FD Linux, LRP (Linux router project Linux Route Project), fli4l, freecso, coyote Linux, smoothwall, etc, these things share a common feature. They are all based on Linux. Some of them can run on a floppy disk, with excellent performance. However, all these soft routes can only support the access of a single broadband line. In the face of hybrid multi-line access requirements, they can only sigh.

Next we will introduce a Linux soft route that supports hybrid multi-line access.

Does an internet cafe need a Linux soft route that supports hybrid multi-line access? Due to the objective conditions of broadband access, many Internet cafes have different lines, such as telecom optical fiber, Netcom optical fiber, ADSL leased line, and dynamic ADSL line. How to make full use of bandwidth resources, reduce Internet access fees, and improve internet access efficiency is a problem that Internet cafes are facing increasingly fierce market competition.

This Linux soft route supporting hybrid multi-line access has two main functions:
1. It is used to bind a gateway to a hybrid multi-line network, such as optical fiber and ADSL. Advantages:
(1). bandwidth accumulation. The bundled bandwidth is the sum of the accumulated bandwidth of all lines;
(2). lines are divided for mutual backup. If a line is faulty, the Internet cafe will not be disconnected and manual switching is not required;
(3). Reduced Internet access costs. For example, 4 m optical fiber + 2 2 m ADSL cables can achieve or close to 8 m optical fiber cables, and the cost is much lower than 8 m optical fiber cables;
(4). Automatic traffic and load balancing;
(5) Avoid the inconvenience of managing multiple gateways. There is only one gateway in the Internet cafe, which avoids the trouble of managing multiple gateways. After adding lines, you do not need to purchase new routes.

2. Smart gateway that implements Policy Routing
For example, an internet cafe has two optical fibers: China Netcom and China Telecom. If some game servers are located on the Internet of China Netcom, it is better to use the optical fiber access function of China Netcom. If the game servers are located on the Internet of China Telecom, it is better to use the optical fiber access function of China Telecom. In this Linux soft route that supports hybrid multi-line access, the optical fiber cables of China Netcom and China Telecom are connected at the same time. Through the definition and setting of policy routes, the website of China Netcom can be accessed, it directly goes through the optical fiber of China Netcom; access to the website of China Telecom directly connects to the optical fiber of China Telecom.

Other functions
1. bandwidth management
In Internet cafes, web pages, file downloads, various chat services, online games, and online movies are used. Real-time network applications are the key services of online games and various chat services. This Linux soft route can set different bandwidth limits and priorities based on different IP addresses and service categories to ensure the bandwidth traffic of important user services.
In addition, this Linux soft route performs special processing on the network game, and the network game port has been specially optimized. Therefore, the speed of playing games is faster than that of routers and proxies.
2. High-Performance Firewall
It can prevent external attacks and malicious damage to internal competitors, such as competitors. This Linux soft route provides the packet filtering Firewall function based on status monitoring, through a simple management interface, you can set filtering rules conveniently and flexibly. The packet filtering function is used at the network layer and transport layer. It monitors data packets based on the packet header source address, Destination Address, port number, protocol type, flag location, and many other information, determine whether to allow data packets to pass through. Only data packets meeting the filtering logic are forwarded to the corresponding destination egress, and other data packets are discarded from the data stream.
3. Anti-Virus Gateway
Traditional routers and proxies only provide the Internet access function. For viruses in the LAN, they cannot be intercepted or isolated. This Linux soft route provides a professional anti-virus gateway, as long as there is a virus machine in the LAN, the system will automatically intercept it and isolate it. This will not cause the whole LAN to be spread frantically, thus saving a lot of manpower and material resources for Internet cafes.
