Abstract
According to an example, a service coordination apparatus may include a processor that is to determine whether each GLB node-pair in a node-pair state table is at a normal state after receiving a DNS request. If a GLB node-pair in the node-pair state table is not at the normal state, a second DNS response may be sent to a node sending the DNS request according to a DNS parsing list. If each GLB node-pair in the node-pair state table is at the normal state, a proximity list may be inquired. If a record corresponding to the DNS request is searched out from the proximity list, a first DNS response may be sent to the node sending the DNS request according to the searched out record. If not, a second DNS response may be sent to the node sending the DNS request according to the DNS parsing list.
