Roots of the Problems Links and servers are facing increasing
pressure. Traditional routing devices are unable to smartly select
the optimal link for outbound traffic and inbound traffic). Traffic
is randomly distributed among the servers, regardless of the
current load or health status of the servers, which may cause link
failures. AD Redundancy of links? Redundancy of servers? Select the
optimal link? Select the optimal server? Take inbound traffic for
example:

Feathered Technology DNS transparent proxy: By the agent of DNS
queries, Sangfor AD evenly assign the users access request to the
internet links(regardless of the DNS address the internal users are
using),ensure efficiency of resource use while taking into account
the user's access speed, opposed to traditional link load
algorithm.
