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.

The present invention relates to a LED wall plate night light and more particularly, to a LED wall plate night light with a ultra-thin assembly by utilizing a simple light-emitting diode (LED) as a source of illumination and a transparent plastic film. When LED light passes through a transparent plastic film, it generates speeding clear light. The transparent plastic film allows light to form an evenly distributed glow, making it a safe and reliable way of illumination.

A system and method of routing a conference call participant to a conference call is disclosed. Participant location data is requested from an electronic device of the conference call participant. The participant location data is received on a system server from the electronic device of the conference call participant. A least cost connection conference call access phone number is determined from an access number group of one or more available conference call access phone numbers based on the location data from the electronic device of the conference call participant. The conference call participant is provided with the least cost connection conference call access phone number.

Devices, systems, functional data and methods are provided for an improved route generation in navigational enabled devices. In generating the route, the available locations are inspected repetitively and locations adjacent to a last selected location are inserted into a first data structure such that the first location of the first data structure is always a least cost location associated with all adjacent locations comprising the first data structure. The first location is then optionally inserted into a second data structure. The generated route includes the current location, one or more first locations, and the destination.

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 adapter is disclosed which allows attachment of a standard telephone to a computer as a standard peripheral. The adapter converts analog signals of the telephone to digital signals of the computer and vice versa. The adapter can also be a stand-alone device allowing the telephone to be attached to a computer network. The adapter, in this case, contains the computing power to support the necessary data network protocols, and PSTN signaling protocols. In this way voice communication is enabled over a computer network without requiring the computers to be equipped with sound cards.

Multiple product, multiple step optimization methods useful for manufacturing products. The optimization methods comprise defining a first group and a second group. The first and second groups each comprise at least two subgroups. One or more of the subgroups for each group comprises one or more variables and one or more constraints. The variables are optimized to obtain final values for the variables based on a defined objective subject to the constraints.

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. This prevents a person having no knowledge of the thumbnail information from obtaining a document from a device main body, thereby tightening security for document management in the main body and providing the document management device capable of fully managing even a document requiring higher security.

A merge join method by a merge join system including a database is provided. The merge join system unequally divides data after a current position of a join column participating in merge join in the database into K partitions, K being greater than 2, and compares the first value of each of remaining partitions excluding the first partition from the K partitions with a value to be searched for the merge join, in order to check whether the first value and the value to be searched satisfy a specific condition. Further, the merge join system determines a partition in which the value to be searched is expected to exist based on a comparison result, and applies a k-ary search to the determined partition.
