Abstract:
N nodes are assigned to a first layer of nodes having a first domain name server (DNS) anycast Internet Protocol (IP) address and a first fully qualified domain name (FQDN). M nodes are assigned to a second layer of nodes having a second DNS anycast IP address and a second FQDN. When a request to resolve the first FQDN for the first layer of nodes is received by a DNS of a node of the first layer and a load on the ES of the node is less than a threshold, the DNS handles the request by returning an edge server (ES) anycast IP address for the ES of the node. When the load on the ES is greater than the threshold, the DNS offloads the request by returning the second FQDN so that the second FQDN of the second layer is resolved to the second DNS anycast IP address.

Claim (Index 1):
A computer-readable storage medium storing computer-executable instructions for controlling a network of nodes, each node of the network of nodes having a domain name server (DNS) and an edge server (ES) to load balance traffic for the ES, the computer-executable instructions comprising computer-executable instructions that when executed:\n access a first DNS anycast Internet Protocol (IP) address and a first fully qualified domain name (FQDN) of a first layer of nodes of the network, wherein the first layer of nodes includes N number of nodes and N is an integer greater than one; and announce the first DNS anycast IP address of the first layer of nodes; and when a request to resolve the first FQDN for the first layer of nodes is received by the DNS of one node of the first layer of nodes:\n when a load on the ES of the one node indicates that the DNS of the one node should not be offloading load from the ES of the one node, handle the request by returning an ES anycast IP address for the ES of the one node; and \n when the load on the ES of the one node indicates that the DNS of the one node should be offloading load from the ES of the one node, offload the request by returning a second FQDN of a second layer of nodes of the network so that the second FQDN of the second layer of nodes is resolved to a second DNS anycast IP address of the second layer of nodes, \n wherein the second layer of nodes includes M number of nodes and M is an integer greater than zero and less than N.
