Secure point to point network communications. Secure point to point network communications are accomplished by sending data across a secure link. Trusted partners at the link are matched to each other. To ensure that no un-trusted partners are on the link, authentication is performed. One of the points may be a secure tap. The secure tap authenticates a trusted partner by receiving a hardware embedded encryption key or value derived from the hardware embedded encryption key from the trusted partner. Data sent on the trusted link is encrypted to prevent interception of the data. The secure tap polices the link to ensure that no un-trusted partners are attached to the link and that the trusted partner is not removed from the link. If un-trusted partners are added to the link or trusted partners removed from the link, the secure tap ceases sending data.

In one embodiment, in a peer-to-peer network, data intended to be transferred directly from a first peer node to a second peer node are first redirected to an interception node. In the interception node, the data may be processed prior to being forwarded to the second peer node. The data may be scanned for virus detection and removal, for example.

Network file systems are mounted to a client arrangement via a local, ad hoc, peer-to-peer network. The client arrangement is coupled to the network, and one or more network file protocols that are compatible with the client arrangement are determined. Using XML-based discovery protocols of the network, descriptors of the one or more network file protocols are sent to a file server coupled to the network. A descriptor of at least one network file protocol compatible with the file server are received from the file server. The compatible file protocol is selected from the one or more network protocols. A network file system provided by the file server is mounted to the client arrangement using the compatible network file protocol.

Embodiments of the present invention provide services that enable individuals to rent and/or purchase content over the Internet and to receive it electronically, referred to below as “EZTakes.” This content may include movies, TV shows, music, games and other information typically distributed on CD/DVD. EZTakes leverages high-speed broadband Internet connections, peer-to-peer networking, digital rights management (DRM) and the growing prevalence of home computers that now typically feature large hard drives (e.g. 180+gigabytes) and have the capability to “burn” (i.e. create) DVDs and/or CDs. EZTakes bridges the gap between the home computer and the living room by using standard technologies that consumers already own and are already familiar with: home computers, DVD media, DVD players and the Internet. EZTakes also promotes the interests of content owners (e.g. movie production companies) by expanding their revenue opportunities through enabling them to distribute their content assets over the Internet. EZTakes also includes technical control mechanisms, such as digital watermarking, that could not easily be exploited when using physical DVD/CD distribution channels.

System and method are disclosed for bridging a point-to-point network such as a Bluetooth scatternet with a shared medium network such as an Ethernet LAN. The scatternet is connected to the LAN via a network access point (NAP). Data packets sent from the LAN to the scatternet are filtered at the NAP to eliminate unnecessary data packets from being sent to the scatternet. Only certain ones of the data packets are forwarded between the LAN and the scatternet. An inter-NAP protocol is used to exchange messages where two or more NAPs are connected to the LAN. Broadcast loops are prevented from occurring in the scatternet and the LAN by defining Administrative domains and NAP service areas (NAPSAs), and controlling the borders thereof according to a broadcast type of the data packets.

A station used as a node in a peer-to-peer communications system keeps a list of stations to which requests for resources may be sent. The list includes for each member a performance parameter. When a station receives a request for resources it selects at least one station from the list and sends a resource request message to it. The selection of the station from the list may be performed by a random or pseudo-random process such that the probability of selection of any station is a function of the stored parameter. A station receiving such a request, for resources that it can itself supply, sends a reply to the originator. When the originator receives a reply it updates the respective performance parameter: the degree of adjustment may vary according to the quality of reply received.

A system, method, and apparatus are directed towards managing a Voice over IP (VOIP) message over a network. A computing device may be configured to select a network connection for which to send the message to a destination based on a variety of factors. Duplicate message packets may be communicated to the destination device through multiple network connections. The multiple network connections may include a peer-to-peer network connection, a peer network connection, an ad-hoc network connection, or the like. Metrics may be collected about the multiple network connections. A determination may be made based, in part, on the metrics whether one network connection is optimal over another network connection. If so, that network connection may be selected to continue to provide the message packets, and the communication of the duplicate packets is ceased.

A method and system of congestion control in a network are provided. A required quality of service (QoS) parameter, such as a maximum allowable latency, for a packet received at a queue in the network, and a route cost metric, such as accumulated and estimated latency, are determined, and the packet is either discarded if the route cost metric exceeds the required QoS parameter, or a discard bias value is set for the packet. Also, if the required QoS parameter exceeds the route cost metric, the method includes determining whether a congestion condition exists in the network, and if the congestion condition exists, biasing the packet for discard based on its latency if the route cost metric for the packet exceeds a threshold. The network may be an IP network, and a network such as a mobile ad hoc network (MANET).

A method and system facilitate peer-to-peer delivery of shipments external of traditional shipping industry channels by listing at least one non-commercial shipment in a non-commercial shipment data set using a shipment listing template. The shipment listing template permits direct listing of the non-commercial shipment by an individual user for delivering the non-commercial shipment to a predetermined destination. Listing at least one non-commercial trip in a non-commercial trip data set through a trip listing template according to a predetermined set of parameters permits direct listing of the non-commercial trip by a non-commercial traveler. Determining a necessary route deviation from the non-commercial trip for delivering the non-commercial shipment to the predetermined destination uses a set of route deviation instructions. Associating the non-commercial shipment data set with the non-commercial trip data set uses a set of matching instructions. The matching instructions facilitate an optimal matching of the non-commercial shipments to one of the non-commercial trips. The matching instructions associate further with the route deviation instructions. The method and system further facilitate a transaction between the individual user and the non-commercial traveler using a set transaction instructions.

A method for adjusting a transmission rate in the transmission control protocol (TCP) under a mobile ad hoc network environment, including calculating a difference value (Diff) between the current transmission rate (cur_bw) and the previous transmission rate (base_bw), setting up upper and lower thresholds by calculating the standard variation (basebw_var) of the previous transmission rate, and updating the previous transmission rate to the current transmission rate depending upon a comparison result of Diff and the size of the upper and lower thresholds.

The invention relates to a method, network node, router, serving node and system for performing multicast in a point to point oriented telecommunication network. The basic idea is to introduce multicast transmission for parts of a network that is basically point-to-point oriented. This is done by creating transport multicast group tunnels between a router and a serving node in order to transport the multicast data. This invention describes the application of multicasting in point to point networks, such as UMTS with a scarce number of resources. In a mobile environment like in UMTS the idea could be implemented by using IP multicast for efficient transmission in the IP network between the SEGSN and GGSN for example on the Gn interface.
