A scalable access filter that is used together with others like it in a virtual private network to control access by users at clients in the network to information resources provided by servers in the network. Each access filter use a local copy of an access control data base to determine whether an access request made by a user. Changes made by administrators in the local copies are propagated to all of the other local copies. Each user belongs to one or more user groups and each information resource belongs to one or more information sets. Access is permitted or denied according to of access policies which define access in terms of the user groups and information sets. The rights of administrators are similarly determined by administrative policies. Access is further permitted only if the trust levels of a mode of identification of the user and of the path in the network by which the access is made are sufficient for the sensitivity level of the information resource. If necessary, the access filter automatically encrypts the request with an encryption method whose trust level is sufficient. The first access filter in the path performs the access check and encrypts and authenticates the request; the other access filters in the path do not repeat the access check.

A method, computer readable media, and apparatus of hierarchical-based communication session and data distribution management that indexes client's communication preferences and network attribute information. Indexing is used to generate dynamic group membership lists that map into communication groups. Indexing is replicated at control nodes in the network overlay to allow distributed management of group membership. Send / receive operations are decoupled through data distribution and the indexing structure. Senders and receivers register their group communication interests to a parent node in the hierarchy. The session control structure aggregates client interest and dynamically updates replicas at control nodes which are selected according to the changes in registered client interest. The indexing structure has self-managing properties for automatic clustering based on client session and data interests, and dynamic partitioning of the session / data interest attribute space. Group membership is managed by querying the indexed session / data distribution management structure and mapping output to communication groups.

A groupware management system for collaborative groups is disclosed that is scalable to support large, dynamic, multiple, and other virtual VPNs. The system may introduce a graph (or hierarchical) structure to the VPN, providing multiple master nodes controlling membership in subsets of the collaborative group. Use of multiple master nodes in a graph-structured (or hierarchical) network topology often relaxes the need for a single, centralized, globally consistent view of VPN group membership, and enables distribution of the management burden among multiple master nodes. Membership in the VPN may be changed dynamically by the second master node for the member nodes of the second subset, without requiring the first master node to dynamically update its group membership records to reflect the change and in many cases without even having to notify the first master node (and vice versa), for example. In further embodiments, the use of multiple master nodes may increase the reliability and efficiency of VPNs, such as by enabling load balancing of master node tasks. Fail-over mechanisms may also be used to transparently re-route management tasks to an alternate master node especially in the case of failure of the current master node serving a given member node.
