Ensuring Incoming Requests to Internal Servers
Each host connected to the Internet has a unique IP address, with which the other devices can therefore find it. In reality, mostly users access online information through human-readable domain names, like google.com or yahoo.com rather than IP address. The Domain Name Systems (DNS) helps solve the issue. It is like the phonebook of the Internet. When a DNS request is received by a DNS server, the DNS server then returns with the IP address of the domain requested initially. DNS translates domain names to IP addresses, while web browsers interact through IP addresses; therefore, browsers can load the Internet resources.

However, incoming requests would possibly not be able to access the hosted servers in case of link failure. Connecting multiple WAN links and taking turn to reply the requests with IP addresses from different WAN links can possibly mitigate the issue. By doing so, the hosted servers then appear as a different IP address to each of the incoming DNS requests. This multiple WAN connections deployment still involve an issue, where DNS server replies DNS requests with IP addresses from the faulty or congested WAN link as DNS server does not check for WAN outage or congestion.

 Inbound Failover & Load Balancing

With the ability of inbound load balancing, Q-Balancer is able to avoid faulty or congested path(s) when directing incoming requests to the hosted servers. Through the inbuilt intelligent algorithms, the incoming requests will be directed to best-performing path or efficiently distributed across the highly available paths. This highly increases the availability and efficiency of the hosted service to incoming requests. Q-Balancer is the best-in-class inbound load balancing solutions and has been successfully deployed by heavy-traffic enterprises to deliver their hosted content to the customers quickly, reliably, and securely.
