An interface for a private IP network interfaces flows of packets between gateway controllers and external media gateways. It has a network address translator and an IPsec device for maintaining secure paths to the external devices. A path identifier records which of the packet flows corresponds to which path. It is incorporated in the packet header, and means that the same interface can be used to couple many different external gateways, and interface them with many of the gateway controllers. Widespread deployment of such interfaces in anonymisers to achieve hiding of device addresses and network topology, as well as the reduction in use of expensive registered addresses is facilitated. By sending the path identifier in the packet, the IPsec device and the address translator can be loosely coupled devices, so standard readily available devices can be used.

An improved system and method for network management is presented which facilitates better administration with a more intuitive reflection of the organizational structure with integrated security concerns by introducing novel strategies for grouping users of a network. In particular, a new group, the Universal Group, is introduced to facilitate nested groups with members in more than one Domain. Members of a universal group may be allowed access to resources across Domain boundaries, where Domains reflect a security boundary in the Network. In addition, the nesting of groups, e.g., within Universal Groups, is enabled, subject to some restrictions, in order to reduce the overhead associated with discovering the groups to which a user belongs. Furthermore, allowing a group to include members without security clearance, but restricting the groups listed on an access token corresponding to a user to groups to which the user has security clearence / authorizarion allows flexible management of groups having similar memberships but different security attributes.

A location register for a mobile communications network is coupled by an SS7 network for passing messages, has a mated location register at a different location to provide geographical redundancy, and has a status detector for detecting a status of the associated register, by sending a heartbeat message to the associated register. It deduces a fail if the message is returned by the signaling network. A cutover manager is arranged to enable a cutover on the basis of at least the detected status. By providing a more positive detection of a failure than merely passively interpreting a lack of response to the heartbeat, false triggering of cutovers owing to transient failures or temporary congestion, can be reduced.

In networked communication systems, a document in a communication (e.g., a response) may be similar between multiple communications involving the same resource, such that duplicate data can be discarded and not stored by a network storage system. Storage of differences in network traffic facilitates compression of storage of network traffic, thereby significantly reducing data storage. Techniques are disclosed for efficient search and retrieval of the compressed data storage. Network traffic may be compared to communications in previous network traffic to identify differences if any. Resource templates may be generated for different (e.g., new) resources identified in network traffic. Storage of the different resources identified in network traffic enables compression of network traffic. Similarity matching may be implemented to improve processing performance for compact storage of network traffic, including determining differences in network traffic for storage.
