Methods and apparatus to provision name-servers

摘要

Methods and apparatus are disclosed to provision name-servers. An example system disclosed herein includes a name-server evaluator to determine capacities of the plurality of name-servers, a provisioner to compute profile assignment values based on a plurality of subscriber identifiers, and an assignor to assign the subscriber identifiers to one of the plurality of name-servers based on the profile assignment values and the capacities.

主权项

1. An apparatus to provision subscribers to name-servers, comprising:
a correcting profile mapping a first name-server to a first range of profile assignment values and a second name-server to a second range of profile assignment values, the first range and the second range based on a first available capacity of the first name-server and a second available capacity of the second name-server, the first range being smaller than the second range when the first available capacity is smaller than the second available capacity; a random number generator to generate a pseudo random number, the random number generator to calculate a profile assignment value for a subscriber based on (a) a subscriber identifier of the subscriber and (b) the pseudo random number from the random number generator; and an assignor to assign the subscriber to one of the first name-server and the second name-server by applying the profile assignment value for the subscriber to the mapping of the correcting profile.
