Abstract: Disclosed is a method for routing data packets, as is a data packet router (10) that operates in accordance with the invention. The method includes establishing an ingress filter (20) in individual ones of a plurality of line cards (14) installed within a router and automatically maintaining a content of an ingress filter table (20A) of each ingress filter in each line card at least partially in accordance with data packets passing through individual ones of the line cards, where the content includes an identification of source addresses of hosts (16) coupled to the router. The method further compares a source address of an incoming packet to a line card to the content of the ingress filter table of that line card, and is thus enabled to detect the presence of an IP packet containing a spoofed IP host address. For a first occurrence of a packet having an IP source address that is not found in the ingress filter table, the packet is forwarded to a route processor (12) for analysis.

Abstract: Systems and methods are provided for browsing miniaturized versions of images stored locally on a mobile device while allowing the associated full-sized image to be transferred to the mobile device as needed. In one embodiment of the invention, a method of viewing an image on the mobile device includes the steps of storing in the mobile device a miniaturized version of an image stored in the mobile device, transferring the image to an external storage device, and deleting the image from the mobile device. In response to the user of the mobile device selecting the miniaturized version of the image, the mobile device sends a wireless message to the external storage device requesting transfer of the full-sized image. The external storage device transfers the full-sized image to the mobile device in a second message and the mobile device is able to display the full-sized image.

Abstract: The invention relates to a method and an apparatus for producing path metrics in a trellis. The trellis phase nodes that have the common nodes of the preceding trellis phase through the allowed state transitions determined by the code are defined as basic group nodes. Then path metrics corresponding to the code are produced, and in each basic group winner information on the winner path and path metric information on the rejected paths is stored in a memory in respect of only one node. Finally the signal is re-processed in the opposite direction trellis phase by trellis phase starting from the path metrics produced last by producing the path metrics of the preceding trellis phase basic group by basic group using the path metrics of the one node of the basic group of the present trellis phase and the winner information and path metric information stored in the memory.

Abstract: Apparatus, and an associated method, for forming a UDP-Lite, or other, data packet with multiple, dynamically-selected, checksum-protected parts. Digitized data is provided to a formatter, and the formatter forms the data packet to include header fields identifying parts of the payload portion of the data packet that are checksum-protected with different checksums. Additional indicia is contained in the header part of the data packet to identify the checksum-type and the checksum-values associated with the separate parts of the data packet. Multiple, contiguous parts of the data packet are checksum-protected with selectable checksum-types, selected by a selector that operates to control operation of the formatter.

Abstract: The invention relates to tracing of a malicious call to be implemented in a telecommunications network, especially in a mobile communication network. The inventive idea is that the called subscriber activates the tracing service in real time on finding the call to be malicious. One way of activating the tracing service is a service code sent from the called subscriber's terminal equipment and defined by the operator. The means required for implementing the service may be located according to the operator's wishes either in a mobile services switching center or in an intelligent network.

A circuit element according to the invention comprises two or more logically entangled bi-directional terminals, wherein each bi-directional terminal can assume any one of three logical states, which are a logical true state, a logical false state, and an indefinite state, in which state the bi-directional terminal accepts one of the logical true and logical false states as an external input from an external source. An entanglement logic resolves the logical state of the bi-directional terminals according to a predetermined set of logical entanglement rules between the bi-directional terminals.
