Abstract: Systems and methods for visualizing traffic coming in from outside to a network to be managed and being sent out of the network. An information presentation apparatus acquires traffic information regarding a traffic specified in accordance with a user's instruction, where the traffic information has been collected from one or more routers located at a border of the network to be managed. The apparatus also acquires path information regarding a path from a start router, through which the traffic passes into the network, to an end router, through which the traffic passes out of the network, referring to stored internal path information. The apparatus then informs a user of the acquired traffic information in association with the acquired path information. At least one of specification of the traffic and determination of the end router is performed referring to stored external path information.

Abstract: A method and an apparatus for implementing a storage function in a passive optical network (PON) system. On the basis of a LINK ID held by the data, data requiring storage, e.g. data making exclusive use of a wide bandwidth such as audiovisual data and large-volume data packages, are determined among all the data sent to an optical network unit. These data requiring storage are stored in a storage device installed in the optical network unit. In case the user requests data stored in the storage device, the stored data are transferred directly to the user, without any need to request and send these data for the second time via an IPTV server and the core network. It is possible to avoid duplicate transfers of data, and in particular to avoid duplicate transfers of data making exclusive use of a comparatively wide bandwidth such as audiovisual data and large-volume data packages, to improve the utilization factor of the downlink bandwidth, and to reduce flow congestion and data delays.

Abstract: Performance of applications such as service capabilities in a container for providing a multimedia service is monitored. Performance monitoring indicates how well the applications are functioning in terms of predefined metrics and also whether the applications are functioning at all. Responses are prompted if performance monitoring indicates that an application is performing below a predefined level or failing to perform entirely. For example, a hung application may be restarted and other applications may alter their manner of function. This allows complex recovery logic through combinations of simple rules.

Abstract: A method and device for detecting and halting specified peer-to-peer (“P2P”) and/or Internet Relay Chat (“IRC” communication sessions based on a priori defined templates is described. Network packets are intercepted and inspected for patterns (defined by the templates) that identify them as definitely, likely or not being associated with one of the specified P2P and/or IRC protocols. Those packets identified as definitely belonging to one of the specified protocols are prevented from reaching their target destination. Those packets identified as only likely belonging to one of the specified protocols are permitted to continue toward their target destination after select information about the particular session/packet is recorded for later use. Those packets identified as not belonging to one of the specified protocols are permitted to continue to their target destination.

Abstract: A mobile node moves from a first IP (Internet Protocol) network to a second IP network in a network system in which the first IP network capable of executing communication in accordance with both first and second kinds of IPs and the second IP network capable of executing communication in accordance with only the first kind of IP are connected with each other. When the mobile node communicates a message with other nodes on the first network after its movement accordance with the second kind of IP, a header for the movement containing both home and foreign addresses of the first kind in IP is added to a header containing home and foreign addresses in the second kind of IP, and put to the message, is added. The message to which the movement header is thus added is used for the communication between a first mobile agent on the first network and a second mobile agent on the second network, or between the mobile node and the first mobile agent.

Abstract: A system and technique for analyzing incoming packets. The path taken by incoming packets can be analyzed from a near end without having access to the far end. This can be done even though packets sent to the far end from the near end, take a different path than that used by the incoming packets. The process is started by an RTP no op packet sent from the near end to the far end. The no op packet request the far end to initiate a trace using a series of media packets that have sequential values in the TTL field. The results of the trace are either send from the far end to the near end and a report is complied at the near end, or the results of the trace are compiled into a report at the far end and the report is sent to the near end.
