According to the invention, autonomous carriers or vehicles are efficiently navigated over a field of operation. The carriers are equipped to execute a selected procedure at more than one desired location on the field, and the navigation system of the invention directs the carrier to the location that is preferentially accessible to it, based on a defined criterion. After the carrier has executed the selected procedure at the location which is preferentially accessible to it, the navigation system directs the carrier to the location which is preferentially accessible to the carrier from the carrier's new position. This procedure is repeated until all the locations at which the procedure is to be executed have been reached. The task of determining a navigation route to a location that can be preferentially accessed is based on an efficient, structured search procedure of low computational complexity.

Distributed traffic engineering route exchanger routers (TE-Xs) are used in an open shortest path first (OSPF) routing area to collect Traffic Engineering Link State Advertisements (TE-LSAs) and exchange the TE-LSAs with other TE-Xs. TE-Xs store TE-LSAs and compute explicit routes required by edge routers. A single point of failure that exists when a single centralized TE database is used is thereby eliminated. The TE-Xs peer with other TE-Xs in a routing area and exchange TE-LSAs to keep traffic engineering link state databases (TE-LSDBs) synchronized. Network resources are preserved for payload traffic and resource reservation collisions are reduced.

A method and system for determining the best data path in a communication network is presented. A Least Cost Routing path between end users in a multi-network environment, including both public and private networks, is determined based upon a longest prefix match. At network activation time, the numbers or prefixes of numbers of end users attached to the public network (304, 305) are stored in entry node data bases A and C of the private network (303). Assuming an end user terminal U1 calls a target end user U3, an entry node B first checks for a longest prefix match between the called number and numbers already stored into its memory. If this is the first time U3 is called via node B, no match will occur and node B will then broadcast a Query to all nodes in the private network (i.e. Nodes A and C). Only those nodes providing possible access to U3 answer this Query. Node B then determines the longest prefix match with the called number amongst the various query answers, and sets the data path via that node having the longest prefix match.

A border gateway protocol (BGP) management system (10) dynamically determines an optimum or preferred data route (12) from wireline networks (18) into a satellite communication system (11). Multiple gateways (16, 30-34) provide access points to the wireline networks. The management system includes a connectivity matrix which processes (74) information, such as bandwidth availability and route congestion, and then generate a BGP update that is communicated (80) into at least one of the gateways. The BGP update promotes preferred gateways and so identifies a preferred access path to the satellite system. Specifically, the BGP update instruction contains a metric altering a weighting of an identified route data route, which metric effects path selection at a gateway receiving IP datagrams. The metric is derived from information pertaining to a connectivity matrix associated with the satellite system.

A protocol and method for provisioning traffic routes in a BLSR SONET network includes request packets that are broadcast from the source node to neighboring nodes. The neighboring nodes determine whether the route associated with a request packet requires less cost than other request packets previously transmitted by the node, or whether the cost exceeds that of the best response seen by the node so far. If the cost is less, the route in the request packet is updated and the request packet is broadcast to the next neighboring node. If a request packet is received more than once at the same node, the request packet is discarded. When the destination node receives a request packet, it generates a response packet that is propagated through neighboring nodes back toward the source node. If the cost associated in the route is higher than another route known by a node, the response packet is discarded. The source node receives the response packets, determines the route with the lowest cost, and issues a connect packet to establish cross-connects between nodes in the route. The source node may also issue a disconnect packet to dismantle a route.

An approach for morphing between planar shapes is disclosed. Correspondences are established between perceptual feature points that are extracted from both source and target shapes. A similarity metric between two feature points is defined using the intrinsic properties of their local neighborhoods. The optimal correspondence is found by an efficient dynamic programming technique. This approach treats shape noise by allowing the discarding of small feature points, which introduces skips in the traversal of the dynamic programming graph. Intermediate shapes are obtained by interpolating the overall shapes constructed by feature points and the detailed information of the shapes respectively.

A document management device obtains thumbnail information as to a requested document out of an image transmitted via a public network, judges as to whether the thumbnail information is correct with respect to the requested document, and returns the requested document when correct.
