Method for DNS response reordering based on path quality and connection priority for better QOS

摘要

Described embodiments provide systems and method for reordering the IP addresses within a DNS response. The servers associated with a domain can often be located across multiple locations. The paths from a client to each of those different servers can have different link qualities. Additionally, the connection between the client and the domain can have different quality requirements. The present solution can consider the link qualities and the connection quality requirements to reorder the IP addresses within a DNS response. By reordering the IP addresses, the system can control to which of the servers the client connects and can ensure that the connection is made over a path that can fulfill the connection's quality requirements.
