Claim:
1. A method for supporting data service address resolution in a network environment, comprising: providing a subnet administrator in a subnet of the network environment; configuring the subnet administrator with a policy, wherein the policy includes a rule, and wherein the rule defines that each data packet sent from a source node in the subnet having a first global identification and targeting a destination node in the subnet having a second global identification is transmitted with a destination local identification of an intermediate node; receiving, by the subnet administrator, a path resolution request from the source node, wherein the path resolution request includes the first global identification and the second global identification; responding, by the subnet administrator, to the path resolution request, wherein the response includes the destination local identification of the intermediate node; sending, by the source node, a data packet to the local identification of the intermediate node; receiving, by the intermediate node, the data packet, wherein the data packet contains the local identification of the intermediate node and the second global identification in the header of the data packet; obtaining, by the intermediate node from the subnet administrator, a local identification of the destination node based on the second global identification of the destination node; and sending, by the intermediate node, the data packet to the destination node based on the obtained local identification of the destination node.
