The Meizo RD588 series Dual SIM 4G Ethernet wireless router is designed to offer a backup 3G/4G network when the primary network fails. The router is using Broadcom chipset, integrated with WAN, LAN, SIM, VPN, VRRP, WiFi, and Serial port services, product line supporting the following radio...
-The Meizo RD588 series Dual SIM 4G Ethernet wireless router is designed for establish 4G LTE cellular and Wi-Fi wireless network and share a cellular broadband connection, which can fallback to 3G/2G networks.
-Powerful, integrated antennas provide stable wireless connections and better coverage.
-With the inclusion of the WAN/LAN port, the TL-MR6400 can also support a wide variety of connection types, including cable, fiber, and DSL modems.
-Take full advantage of your cutting-edge 4G LTE network, which can achieve high download speeds. It allows you to share your 4G LTE network with multiple Wi-Fi devices so you can enjoy uninterrupted HD movies, rapid file downloads, and video chats that won't freeze up.
-The router is using Industrial Grade equipment design standards, passing CE and EMC test, stable and reliable. External antenna connectors make it possible to attach desired antennas to easily find the best signal location. Multiple encryption protocols as L2TP, IPSec, PPTP and GRE are owned, making it ideal solution for applications in which high data bandwidth and strong stability is required.

The Concept of Failover and how Load Balancers help in the process
Load balancing also provides the failover functionality. Failover is a concept or rather a process of the continuation of a service after the failure of one or more of components. It fails over to the next component. The components of load balancers are monitored continually and when one is non-responsive, the load balancer is informed and does not send traffic to it. When the component is back on line, the load balancer routes the traffic to it all over again. In order for this to operate, there should be at least one component outside the service's capacity.
This is less expensive and more flexible. That is, a single "live" component is coupled with a single backup component that helps in the time of a "failure".
VPN Load Balancing Technologies
An important addition designed to offer all the features in an enhanced format is the Virtual Private Network (VPN) Load Balancing functionality. The software makes use of the built in Internet Protocol Security (IPSEC) support to access a network of VPN tunnels that is established between two desired locations. The merits of this technology are:
Doubling of the VPN bandwidth.
Helps in remaining protected in case of the link failure even when one link collapses at each site. This software also offers in-built or additional ADSL ports.
