Abstract: A state machine circuit converts a first network packet into a second network packet according to modification actions from a textual language specification. Each modification action is either an insertion action inserting a data segment or a removal action removing a data segment. Each state corresponds to a pairing of a first data word from the first packet and a second data word from the second packet. Each state selects the data units of the second data word from the data segment of each insertion action and the data units of both the first and a prior data word. Each state specifies one or more next states including the state corresponding to the pairing of either the first or a next data word after the first data word in the first sequence and either the second or a next data word after the second data word in the second sequence.

A logical data tunnel is formed and includes one or more packet flows. Each packet flow includes individual packets having a shared destination address. Bandwidth allocated to control an aggregated flow of packets routed through the logical data tunnel. A transfer rate is assigned to control each packet flow transiting within the logical data tunnel.

Abstract: The transformation of data between binary data and hierarchical data, such as might be processed by an Infoset Processor. When data is received from a network in binary format, the transformation module transforms the binary data into a hierarchical data representation of the binary data, and then provides the transformed data to message processors (e.g., Infoset processors) that understand the hierarchical schema. The transformation module may also transform hierarchical data into binary data for transmission on a network.

Abstract: A method and apparatus for updating the system configuration settings of a computer system. Embodiments include a remote system configuration system that enables a user to update the system configuration of a target machine from a server machine over a network or similar communications system. Another embodiment includes a system configuration method using a bus master device to write system configuration data into a target computer system.

Abstract: A modified form of the UDP multicast protocol is disclosed to implement a one-way notification method between a server and one or more clients. The UDP multicast notification method enables UDP messages to be sent only to registered clients, not broadcasted to all clients. This architecture minimizes network traffic and enhances system security, since only registered clients receive the UDP message. The configuration of the UDP multicast notification method does not require the configuration of network devices in order to support a UDP multicast. Furthermore, any number of the clients may be on a different network domain than the DCM engine.

Abstract: A method and apparatus for binding a first wireless communication unit installed on a first asset and a second wireless communication unit installed on a second asset, wherein the first asset is connected to the second asset by electrical power lines. The method and system can be used for binding a wireless communication unit of a tractor and a wireless communication unit on a trailer. The method monitors the current in the auxiliary power connection between the assets. By transmitting and detecting power pulses through the auxiliary power line, the wireless communication units can ensure that the two assets are attached and therefore it would be proper to establish a wireless connection between the two wireless communication units. The number of power pulses can be used to identify differing devices. Such method can also be used to detect an open fuse or circuit breaker. In the case of an open fuse, voltages can be used in place of power pulses to complete the binding process.

Abstract: A system and method of managing objects in a wireless user terminal is described. When an object is created or added to a user terminal, the user terminal assigns a temporary ID to the object. The wireless user terminal can also be coupled to a server by a network. The object or a copy of the object and the object's temporary ID can also be transferred to the server. The server can then assign a permanent ID to the object. The permanent ID of the object can also be transferred to the wireless user terminal.

Abstract: A message, which is to be routed to one of a plurality of authorized parties comprising a first authorized party and a second authorized party, is received by a routing system. A Web service is polled to detect for a presence of the first authorized party. After determining that the presence of the first authorized party remains undetected over an allocated time interval, the Web service is polled to detect for a presence of the second authorized party. In response to detecting the presence of the second authorized party, the message is routed to an active communication device associated with the second authorized party.

Abstract: An Internet Service Provider (ISP), in consideration of being remunerated in some manner by an e-merchant, carries the packets of a designated subset of that e-merchant's clients, designated as VIPs, in a privileged class of service as compared to an unprivileged class of service that is used to carry the packets of the e-merchant's other regular clients. In this way, the adverse effects on performance due to congestion in the unprivileged class of service, whether due to an ongoing denial-of-service attack or not, will not affect the performance of packets sent by and to VIPs using the privileged class of service. An e-merchant may select its VIPs from among those clients that bring in a majority of the e-merchant's revenues. An e-merchant turns a regular client into a VIP by granting it a VIP right.

Abstract: Demographic information of an Internet user is predicted based on an analysis of accessed web pages. Web pages accessed by the Internet user are detected and mapped to a user path vector which is converted to a normalized weighted user path vector. A centroid vector identifies web page access patterns of users with a shared user profile attribute. The user profile attribute is assigned to the Internet user based on a comparison of the vectors. Bias values are also assigned to a set of web pages and a user profile attribute can be predicted for an Internet user based on the bias values of web pages accessed by the user. User attributes can also be predicted based on the results of an expectation maximization process. Demographic information can be predicted based on the combined results of a vector comparison, bias determination, or expectation maximization process.

Abstract: A method, system and apparatus for reducing dataflow disruption when increases in path maximum transmission unit (PMTU) are being detected are provided. Conventionally, when increases in PMTU are being detected, an increased-in-size data packet is sent by a transmitting host. If an intermediate link is unable to process the data packet through, it drops the data packet and sends an error message to the transmitting host. The transmitting host has to reduce the size of the data packet and resend it. The procedure outlines in this disclosure obviates the need to resend the data packet. It does so by transmitting an old data packet that has been increased in size. Hence, there is no need to resend the data packet if it is dropped.
