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 13):
A network of nodes, each node of the network including a domain name server (DNS) and an edge server (ES), the network comprising:\n a first layer of nodes including N nodes, wherein N is an integer greater than one, and wherein the first layer of nodes has:\n a first DNS anycast Internet Protocol (IP) address for the DNSes of the ESes of the first layer; and \n a first fully qualified domain name (FQDN) for the first layer of nodes; and \n a second layer of nodes including M nodes, wherein M is an integer greater than zero and less than N, wherein the second layer of nodes has:\n a second DNS anycast IP address for the DNSes of the ESes of the second layer of nodes; and \n a second FQDN for the second layer of nodes, and \n wherein the DNS of one node of the first layer of nodes includes:\n a component that either:\n handles a request to resolve the first FQDN for the first layer by returning an ES anycast IP address for the ES of the one node; or \n offloads the request to resolve the first FQDN for the first layer by returning the second FQDN of the second layer of nodes 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; and \n \n a load controller that monitors load on the ES of the one node and that, based on a load on the ES of the one node, directs the DNS of the one node to handle requests or offload requests.
