Creating directed circuits including encoding of policy and state information associated with directed circuits that may be established between two network entities on separate protected networks. The policies are maintained and implemented according to security methods that initially belong to network apparatus on either of the two protected networks; however the security methods may be relinquished to trusted third parties.

Method for establishing directed circuits between parties with limited mutual trust

A method of transferring information across a computer network with a server and a client. The information is divided into a plurality of cards and a plurality of card forms. Each card includes a plurality of values. Each card form corresponds to one of the cards and includes a description of the values of a corresponding card. The cards and the card forms are stored in a server data base on the server and a client data base on the client. The information in the server is changed or replaced by attaching a card delta to one of the cards. The card delta indicates which information in the respective card is to be replaced. The card deltas are transferred between the client data base and the server data base when data bases are to be updated.

Method for encoding and transporting database objects over bandwidth constrained networks

A local net area network, or LAN, configuration is provided with a multiple generic LAN channel architecture which can be logically and dynamically changed. The configuration control can be applied to each module of the network and to each port of a module of a LAN hub. The architecture provides multiple LAN protocols to be used simultaneously, as needed, through protocol specific functions. Industry standard protocol such as: token bus, token ring, and fiber distributed data interface (FDDI), can be implemented using the generic channel architecture and its characteristics providing respective network functions. The architecture also provides a digital collision detection method and provides information necessary for precise network statistics monitoring. The token passing ring architecture provides a logical ring formation within the generic channel. A token passing bus architecture uses modified Ethernet.TM. architecture, and a hub management provides control for the generic multichannel and the LAN management provides protocol dependent network management. The architecture provided allows multiple hub management entities via hub mastership arbitration to provide a unique master for the hub management function.
