Abstract

See full text

A mechanism is provided for recovering from a catastrophic failure that results in a large number of user endpoints attempting to come on line simultaneously after an NGN is restored. In an enhanced DNS load balancer, DNS queries from the user end points relating to a particular NGN edge device are selectively dropped if a rate of queries for the particular edge device suddenly increases or exceeds a threshold. The query dropping may also be based in part on the class of service assigned to the user endpoint.
