摘要

Disclosed is a method performed by a gateway server. The method may include the following steps: receiving from a client belonging to a first address realm a request for a network resource from a second address realm; allocating a network resource from the second address realm to the client in response to the request; detecting that the client is not able to communicate with the gateway server; in response to detecting that the client is not able to communicate with the gateway server, setting a retention timer, wherein the retention time is associated with the client; detecting the expiration of the retention timer if the retention timer has not been deactivated; and after detecting the expiration of the retention timer, adding the network resource to a set of available network resources.
