Multi-Wan port router technology:
At present, the Internet has been deeply integrated into our lives. Broadband routers are the most widely used Internet access tools for common household users and small and medium-sized enterprises. We all know that the earliest Broadband Router solution is IP sharing, that is, to allow multiple terminals in the internal network to share a broadband egress, the core technical application is the simple NAT-network address translation function. Therefore, the old-fashioned Broadband Router is also called an IP sharing device ".
As your network application requirements increase, NAT alone is not enough. In particular, users have urgent requirements on network security and other functions to ensure the safe and smooth operation of the network. The design of broadband routers is increasingly complicated, including FIREWALL, DMZ, and virtual servers, as broadband routers have embarked on a multi-functional road, various SOHO router products have emerged.
Now, the other development trend is becoming more and more obvious. Broadband routers are gradually coming out of SOHO and home applications, and are selected by the majority of enterprises as networking devices for medium-scale networks, in this environment, enterprise users impose more complex functional requirements on Broadband routers, such as faster speed, more secure, manageable, and diversified application modes. As a result, broadband routers are showing a diverse development trend. A wide variety of products with different performance constitute the rapidly growing SMB Broadband Router market.
Among them, the Broadband Router with multiple WAN ports is such a special SMB Product Series. It has changed the "one-to-many" broadband access method into a "many-to-many" method, fully satisfying the desire of enterprise users to own more bandwidth at no cost. This type of router allows users to share 2-4 broadband external lines in a LAN, without dividing the internal network into several independent parts based on the number of WAN ports. In fact, its working mechanism is to distribute all kinds of request data in the LAN to different broadband outlets based on the preset load balancing policy, the requested data is then returned from the egress, so as to achieve intelligent dynamic information delivery. Since Session requests in Lan are distributed and continuously distributed, after allocation, it seems to be like expanding the egress bandwidth of the entire LAN, which doubles the bandwidth.

Multi-Wan port broadband routers are technically complex and require high hardware processing capabilities. The processing of Multi-WAN ports is not a standard network protocol, and there are no standards to follow. It is just an implementation strategy. Therefore, due to different technical capabilities and on-site debugging environments, the similar products of different manufacturers vary greatly. To achieve high-speed data packet distribution and collection, complex algorithms must be constantly optimized to ensure accuracy, efficiency, and adaptability. Therefore, the design engineer's embedded software requires a high level of skill.
At the same time, the multi-Wan port router must use a high-speed CPU and a large-capacity storage device, otherwise it is not competent for parsing each IP packet. The low-speed CPU processing capability is insufficient, which may cause the internal software system to crash, and the router has to crash frequently. According to the analysis of practical results, vrouters with a CPU rate of more than 150 Mips can basically adapt to the working intensity requirements of Multi-Wan Port Routers, and vrouters with a CPU of less than MB, in many environments, the probability of dead-end failures is extremely high, and it seems a little too short to use.
The load balancing mechanism of a Multi-WAN port router is not available for a single WAN port, and is also the most special application mode for multiple WAN ports. Common Server Load balancer mechanisms include Session, Session, Traffic, and manual Server Load balancer.
In addition, the multi-Wan port router can also act as line backup. Once a broadband line fails, the other line will assume the data requests of all users, this reinforces the entire network system and avoids catastrophic consequences caused by network egress paralysis. Especially for operational Internet cafes, line faults not only cause financial losses, but also cause serious consequences of customer loss, which cannot be borne by Internet cafe owners. Similarly, for some enterprises with relatively high informatization level, the daily dependence on the network system is heavy, and the office business network must be unable to leave. A network system without backup also has a huge potential risk. Therefore, choosing a vro with multiple WAN ports is a wise way for managers to prevent them from happening.
Network Topology
To sum up, using a multi-WAN router has the following three benefits:
1. Increase the egress bandwidth. Taking TP-LINK's dual WAN port router TL-R480 + as an example, using two ADSL or Ethernet broadband lines, because the two WAN ports can be load balancing, therefore, the total egress bandwidth is doubled to the original one. At present, both ADSL and 10 M Ethernet bandwidth have very low monthly subscription fees, and the costs of applying for more bandwidth are limited, bandwidth grows exponentially with limited costs, which can be achieved for larger networks.
2. Line backup. Using a multi-Wan port router, applying for multiple lines and using multiple Modem, these lines can also be of different carriers, such as China Telecom's ADSL and 10 M Ethernet of China Netcom, when an ISP, cable, or Modem fails, the data traffic will be re-allocated to a non-Faulty port, and the entire network will not be interrupted.
3. Provide more content services. Different ISPs provide different game, chat, video-on-demand, and other services. These different content services are placed on the ISP Server. to enjoy these services, you must apply for corresponding ISP access. To provide multi-ISP content services, you must apply for multi-ISP access and use a multi-Wan port router.

TP-LINK TL-R480 +/TL-R488 Broadband Router
TL-R480 +
TL-R488
TL-R480 + is a dual-WAN port for High Performance Broadband Router. The TL-R488 has four WAN ports that allow four incoming lines. The main difference between TL-R488 and TL-R480 + is that on this port, the TL-R488 has 4 WAN interfaces and 1 LAN interface, the TL-R480 + has 2 WAN interfaces and 3 LAN interfaces. In terms of performance, the two are basically the same, taking TL-R480 + as an example, the typical load of 150 ~ 250 sets, compared with the early launch of the TL-R480, is unique in the high speed based on the dual WAN port, can be directly connected to two incoming lines, multiply the egress bandwidth, and can connect to different ISP, enjoy more services. With a dynamic and automatic load balancing policy, you can perform backup and load balancing without manual intervention. Automatic line fault shielding/recovery. Traffic is automatically re-allocated when a fault occurs.
Compared with other brands, TP-LINK multi-Wan port router has the following advantages:
1. The load balancing policy of TP-LINK is a dynamic automatic traffic allocation policy based on the bandwidth ratio, which does not require the user to understand the technology, think about the strategy, there is no configuration option of the load balancing policy on the user interface, everything is automatically completed by the router, and when the WAN port changes, such as line failure and recovery) will be automatically adjusted to the most reasonable state, do not interrupt the work of the router, or manually adjust.
2. automatic backup policy. Generally, a multi-Wan port router has a backup policy option or backup mode on the configuration interface.) Which of the following is the main line must be specified, which is the backup line? Normally, only the main line works. The backup line is enabled only when the main line fails. TP-LINK multi-Wan port router adopts automatic adaptive backup policy, and combined with load balancing policy can achieve seamless backup.
In addition, the TP-LINK multi-WAN port router has the following three special features, that is, allow each WAN port to enable or disable the default full enable) you can specify a priority channel by source IP address and a channel by destination IP address.
