利用分层边缘服务器的负载平衡
Abstract:
一种包括边缘服务器(132)、域名服务器，DNS(131)和负载控制器的边缘服务器节点(130)。DNS被分配给边缘服务器节点层，其中每一边缘服务器节点层都具有该层的DNS的DNS任播IP地址和该层的完全限定域名FQDN。DNS处理或卸载请求以解析所分配的层的FQDN以便平衡边缘服务器上的负载。通过返回另一层的FQDN来卸载请求。负载控制器监视边缘服务器上的负载，并指示DNS卸载请求以便减少边缘服务器上的负载。
Abstract(English):

An edge server node comprises an edge server, a DNS, and a load controller. The DNS is assigned to a layer of edge server nodes where each layer of edge server nodes has a DNS anycast IP address for the DNSs of that layer and a FQDN for that layer. The DNS either handles or offloads requests to resolve the FQDN for the assigned layer to balance the load on the edge server. A request is offloaded by returning the FQDN for another layer. The load controller monitors the load on the edge server and directs the DNS to offload requests to reduce the load on the edge server.
