    摘要: A remote facilitation network (10) includes a base computing equipment environment (12) having a computer (14) and a control and activation device (16). A remote user (18) requests communications with the base computing equipment environment (12) through a wireless paging service (20). The remote user (18) generates a paging message that is transmitted by the wireless paging service (20) and received at the control and activation device (16). The control and activation device (16) processes and interprets the paging message in order to activate the computer (14). The paging message includes a callback number that is transferred from the control and activation device (16) to the computer (14). The computer (14) dials the callback number in order to establish a communication link with the remote user (18). After identification and verification, the computer (14) relinquishes control of the communication link to the remote user (18) such that information exchange can be initiated between the computer (14) and the remote user (18).

    摘要: A control and distribution protocol (CDP) is implemented for transport across a backplane bus, through a high-speed serial link or through a switching fabric connection. The protocol includes an intra-system transport of dynamic routing protocol (DRP) IP messages, the distribution of routing information within the router, the transport of control and maintenance messages, and the transport of IP and multi-protocol label switching (MPLS) traffic between ingress and egress ports. The protocol further includes a dynamic routing and control driver which interacts with dynamic routing control applications to exchange messages that are to be transmitted to packet flow processors and to handoff messages received from packet flow processors. A packet flow processor driver which services messages carried between the dynamic routing control and packet flow processors. An IP traffic interface provides transfer of IP L3/L2 protocol data unit (PDU) header primitive from the packet flow processors. Both the DRC driver and PFP driver include a framework transport interface.

    摘要: Method and system for implementing an inter-domain constraint-based shortest path first (“IrD-CSPF”) technique for supporting hierarchical routing in interconnected multi-domain OTNs are described. In one embodiment, the invention is a method for calculating a network path in an interconnected multi-domain network. The method comprises receiving a path setup request message for a new traffic flow in the network identifying a source node in one domain of the network and a destination node in a second domain of the network; determining a common ancestor hierarchical routing domain that includes ancestor nodes of both the source and destination nodes; calculating an inter-domain path from one ancestor node to the other ancestor node that determines, for each lower-level domain, border nodes in the domain from the source node to the destination node; and for each bottom-level domain, calculating an intra-domain path between the border nodes that were determined for the domain.

    摘要: A signaling network gateway device (12) is provided for use in a signaling network (10), such as a Signaling System 7 signaling network. The signaling network gateway device (12) includes a protocol interface unit, a signaling transport unit, and a signaling gateway control unit (58). The protocol interface unit converts signaling information between a first format and a second format and exchanges signaling information in the second format with a user access element, such as a digital loop carrier (26), of the signaling network (10). The protocol interface unit may include any number of individual protocol interface units such as an ISDN protocol interface unit (50), a future protocol interface unit (52), a TAPI/TSAPI protocol interface unit (54), and an SS7 protocol interface unit (56). The signaling transport unit performs link speed conversion on the signaling information in the first format so that the signaling information may be exchanged with a transport signaling link, such as a link (15), of the signaling network (10) at a desired rate. The signaling transport unit may include any number of individual signaling transport units such as an SS7 signaling transport unit (68) and an SS7/ATM signaling transport unit (70). The signaling gateway control unit (58) controls an exchange of signaling information in the first format between the signaling transport unit and the protocol interface unit.
