A method in a configuration server for configuring a communication system comprises configuring a plurality of nodes in a first cluster, and configuring a plurality of nodes in at least a second cluster, such that the configuration server acts as a common configuration server for at least first and second clusters. A method in a node associated with a cluster comprises determining a configuration service address relating to a common configuration server that is adapted to configure the cluster associated with the node and at least one other cluster, sending a request for configuration information to the common configuration server, and receiving configuration information from the common configuration server.

According to an embodiment of network address translation traversal, a server agent interfaces a private network to a public network. Private IP addresses for servers located in the private network are mapped to corresponding identifiers known to clients located outside the private network. A request message sent over the public network by a client located outside the private network is received by the server agent. The request message includes a host identifier having a first portion that identifies the server agent to the public network and a second portion that identifies a server located in the private network. The second portion of the host identifier is unknown to the public network. The request message is sent to the server identified by the second portion of the host identifier using the private IP address that maps to the second portion of the host identifier.

Packet data are efficiently communicated from a packet data network to a mobile subscriber by way of a mobile communications network. When the mobile communications network receives a message from the packet data network intended for the mobile subscriber, an available mobile communications network packet address is dynamically assigned from a pool of packet addresses to the mobile subscriber. Thereafter, packets included in the data message are routed to the mobile subscriber using that dynamically-allocated address. When the address is no longer needed, it is returned to the pool. Each packet address in the pool includes a corresponding indication that designates whether that address is allocated or available for allocation. A correspondence is established between a name associated with the mobile subscriber (e.g., an Internet domain name), and a mobile subscriber identifier (e.g., an IMSI). A dynamically-assigned packet address is associated with the corresponding mobile subscriber name and identifier. Thereafter, packet data from the packet data network that include the mobile station name are directed to the mobile subscriber using the corresponding mobile subscriber identifier and the associated, dynamically-allocated packet address.
