Abstract: Application-layer signaling of a packet data network, such as the Session Initiation Protocol (SIP), is used to communicate with an interworking interface between the packet data network and a circuit-switched network, particularly a public land mobile network (PLMN), wherein the interface converts the application-layer signaling of the packet data network to a control protocol utilized in the PLMN, wherein a private user identification is carried, for example, by means of a Session Description Protocol (SDP) within the application-layer signaling between the packet data network terminal and the interface, and wherein standardization of lower layers of the packet data network protocol stack is not required beyond that which is already defined. The interface between the packet data network and the circuit-switched network provides the private user identification to the circuit-switched network in the manner in which the circuit-switched network is accustomed.

Abstract: A way of reducing the impact of denial of service attacks is presented. For each connection request received by a server, the server attempts to establish a connection to accommodate the corresponding request. For each connection request that the server cannot currently handle, the connection request is placed in a backlog queue for future handling. If one or more of the backlog queues have entries, connection sockets that have connections but no received request data are identified and disconnected. Such connection sockets would be highly suspect of being generated as a result of denial of service attacks. Upon disconnection, resources are freed for legitimate requests thereby improving server performance even during denial of service attacks.

Abstract: An isochronous channel is configured on an interconnect bus between a first device and a second device. A first device requests an isochronous channel, required bandwidth, and a required service window size. If a service window of the required size at the required bandwidth is available, an isochronous bus controller sends the request to the second device. If the second device has a service window of the required size at the required, it accepts the isochronous channel request. The isochronous bus controller can be a collection of isochronous controllers, each controlling a subset of the interconnect bus. The isochronous bus controller then allocates bandwidth to the first device, notifying the first device to begin generating isochronous transactions, controlling access to the bus to ensure the first device does not exceed the bandwidth allocation. Further, the isochronous bus controller terminates the isochronous channel, if the first device stops sending isochronous transactions.
