Abstract: The invention relates to a system and method called autotopology of a network or advertising based network management which enables the analysis and automatic graphical and hierarchical representation of any hierarchical or flat network topology, especially a switched Ethernet (SE). The autotopology can be used for self-configured networks (for example by using zeroconf) and for any otherwise configured networks, especially using DHCP or manually configured networks. The use of zeroconf is called autoconfiguration. Autoconfiguration and autotopology enable a comfortable and safe administration of a network. Administration of a self-configured network using the autotopology data proceeds in a separate and low-priority sub-network (link local) so that the productive operation of the network remains undisturbed. The topology of the network is used as a clear possibility of administering a network. Administration of the network is possible immediately after determination of the topology.

Abstract: A device retrieval system in a network system including a plurality of devices each having at least one attribute. The retrieval system includes: a plurality of device registration units, a device retrieval unit and an identity judgment unit. The device registration unit registers at least a part of the devices and attributes thereof while associating the devices with the attributes respectively. The device retrieval unit retrieves devices and attributes thereof from the devices and the attributes registered in the device registration units. The identity judgment unit judges identity as to whether a device retrieved from one of the device registration units is identical to a device retrieved from one of the others of the device registration units, based on common points of attributes of the retrieved devices.

Abstract: A signaling method for use in a communication network, in particular a unified network, for supporting a communication along a communication path (12) via a plurality of in-path network infrastructure elements (6, 8, 10) of the network. A service element (26, 28) of the network which is located off the communication path triggers an in-path network infrastructure element (6) and the triggered in-path network infrastructure element initiates in-path signaling along the communication path. In particular, the service element may send a message to a terminating end point of the communication, which message is intercepted by the network infrastructure element (6) closest to the terminating end point, which closest network infrastructure element initiates the in-path signaling.

Abstract: A tiered distribution service is provided in a content delivery network (CDN) having a set of surrogate origin (namely, “edge”) servers organized into regions and that provide content delivery on behalf of participating content providers, wherein a given content provider operates an origin server. According to the invention, a cache hierarchy is established in the CDN comprising a given edge server region and either (a) a single parent region, or (b) a subset of the edge server regions. In response to a determination that a given object request cannot be serviced in the given edge region, instead of contacting the origin server, the request is provided to either the single parent region or to a given one of the subset of edge server regions for handling, preferably as a function of metadata associated with the given object request. The given object request is then serviced, if possible, by a given CDN server in either the single parent region or the given subset region.

Abstract: In a computer system, peripheral computers with business applications send alert messages to a central computer when a current variable exceeds a reference value. The central computer implements an alert server to notify a target group of multiple users via communication devices. The central computer escalates further notification to a supervisor user in the event that during a predetermined time period no user of the group has confirmed reception. The notifications have predefined fixed and variable text portion that relate to the alert type. The group of users to be notified is determined by subscription or by a role-to-application assignment.

Abstract: The present invention is directed to voice communication devices in which an audio stream is divided into a sequence of individual packets, each of which is routed via pathways that can vary depending on the availability of network resources. All embodiments of the invention rely on an acoustic prioritization agent that assigns a priority value to the packets. The priority value is based on factors such as whether the packet contains voice activity and the degree of acoustic similarity between this packet and adjacent packets in the sequence. A confidence level, associated with the priority value, may also be assigned. In one embodiment, network congestion is reduced by deliberately failing to transmit packets that are judged to be acoustically similar to adjacent packets; the expectation is that, under these circumstances, traditional packet loss concealment algorithms in the receiving device will construct an acceptably accurate replica of the missing packet.

Abstract: In a peer-to-peer collaboration system, deltas containing data change commands are organized in a persistent data structure called a delta log. The delta log is organized into blocks, which are the largest division in the delta log. In turn, blocks contain groups, groups contain chains and chains contain deltas. Delta blocks are used to implement priority deltas that are used to limit the collection of data change commands that must be transferred. Within a block the deltas are organized by groups, each of which is a set of deltas organized into chains. The delta group in used to determine which deltas to purge. The chains are ordered by increasing creator ID of the endpoint that created the chain. Organizing the delta log in this fashion allows the log to be “walked” to detect convergence problems. To achieve causality-preservation, each delta has a list of dependencies representing other deltas that must be executed before the current delta can be executed.

Abstract: Method and apparatus for authorizing Internet transactions using the public land mobile network (PLMN). An association, or linking, of a mobile terminal to a transaction being made with a more traditional Internet access device such as a PC is provided using the resources of the public land mobile network (PLMN). The mobile terminal can in turn be used to provide authentication and/or authorization for the transaction. The link or coupling between the transaction documents or information sets presented on the two devices can be created by a service provider or merchant sending a WAP push message to the mobile terminal. Authentication and/or authorization can be provided using the client-side PKI capabilities of the wireless terminal, using a user ID and/or password, or through other means.

Abstract: Methods, computer systems, and computer readable media provide for automated control of the status of network address space. Blocks of networking address space assigned to a network may be allocated from a free status to a new status based upon a request to allocate a particular size block. Blocks of networking address space assigned to a network that have been allocated to a new status may be deallocated to return to a free status based upon a request to deallocate the chosen block. Blocks of networking address space assigned to a network that have been allocated and otherwise manipulated such as through a lend from another network may be reclaimed for the original network upon a request to reclaim the chosen block.

Abstract: A mutual recognition process is performed in step S1. When it is determined in step S2 that a request for sending a list of musical pieces has been received, the list of musical pieces is sent in step S3. When a request for sending audio data has been received in step S4, a transfer-rate measurement process is executed in step S5. When it is determined according to the transfer rate in step S6 that the audio can be transmitted, the corresponding compressed audio data is extracted in step S7, the compressed audio data is decoded to generate linear PCM data suited to the transfer rate in step S8, and transmitted in step S9. When the audio data cannot be transmitted, an error message is transmitted in step S10. The present invention can be applied, for example, to a server for distributing audio data and an audio player terminal for reproducing the distributed audio data.

Abstract: Methods of operating a first endpoint device (ED) facilitate the making of a peer-to-peer (P2P) connection between the first ED and a second ED despite intervening network address translators (NATs) at both ends. The P2P connection extends across a system compliant with the internet protocol (IP) whose architecture that includes a first network (having at least the first ED and a first NAT), a second network (having at least the second ED and a second NAT) and a third network. The first ED connects to the third network via the first NAT while the second ED connects to the third network via the second NAT. A first such method includes: providing the second ED with the first IP-address/port pair; and providing the second ED with first type-information regarding the type of the first NAT.
