摘要： A method and apparatus for providing distributed communication routing includes a route computation engine operably coupled to a plurality of forwarding engines within a logically distributed router. Registration information is provided to the route computation processor by the forwarding engines, and the forwarding engines are recognized and identified by the route computation processor in response. The registration information includes information regarding interfaces or connections amongst the forwarding engines and external routers and other external destinations. The route computation processor provides control information to at least one of the plurality of forwarding engines for distributed routing maintenance and/or specific data forwarding operations. Distributed routing maintenance includes monitoring the status of the forwarding engines, while specific data forwarding operations include tunneling messages relayed to and from the route computation processor by the forwarding engines and packet formatting information that controls how the format of packets forwarded by a forwarding engine.

摘要： The digital data stream (e.g. ATM cell stream) replicating device features an input port for receiving a continuous digital data stream at an input transmission rate; a broadcast mechanism for replicating the input digital data stream N times; N output ports for transmitting each such replicated digital data stream through a separate output port at an output transmission rate at least equal to the input transmission rate; and a delay mechanism for introducing a relative delay for each said output digital data stream with respect to the input digital data stream such that the output streams are identical but out of phase with one another. Use of such a device enables a multi-port digital data communications device such as an ATM network switch to be tested using only one (expensive) performance test generator while still respecting the statistical multiplexing advantages of the multi-port digital data communications device.

摘要： A system and method of tracking an error condition detectable in a communication network is provided. The method includes generating first derived communication attributes from collected statistics from the communication network in a first time interval and retaining the first derived communication attributes. The method further includes generating second derived communication attributes from collected statistics from the communication network in a second time interval, comparing values for the first and the second derived communication attributes to generate a comparison result and utilizing the comparison result as a factor in determining a status of the error condition.

Each of the first and second communications components include an optical laser for transmitting and receiving laser signals to and from each other through the optical links. In an embodiment, the method comprises the steps of: (a) initializing each of the first and second communications components; (b) enabling the optical lasers and optical sensors; (c) exchanging idle packets between the first and second communications components to establish a datapath across the optical links; (d) exchanging test data packets across the datapath established in step (c) to verify connection of the optical links; and (e) upon verification of connection of said optical links in step (d), enabling data flow between said first and second communications components. In particular, this method is applicable to synchronizing data transmission across a parallel optical link comprising a plurality of parallel links.

摘要： This patent concerns a system and method for detecting a mass calling event in a telephone system and to regulate telephone calls to a call destination for which a mass calling event has been detected where a packet transport network and Call Server is integrated into the Public Switched Telephone Network (PSTN). A packet transport network and a central Call Server implement switching functionality traditionally provided by numerous Time Division Multiplexing (TDM) switches within the PSTN. A credit bucket mechanism is used for call regulation in a mass calling event. The packet network may be based on (but is not limited to) ATM, Frame Relay, or IP packet protocols.

摘要： A method and apparatus for adaptive service interworking include processing that begins by obtaining connection information of a receiving end-point network switch in response to receiving a setup message from a sending party. The setup message identifies a receiving party, which is operably coupled to the receiving end-point switch. Such connection information may be obtained by sending an enhanced traffic descriptor appended to the setup message and receiving an enhanced traffic descriptor that was appended to a connection message from the receiving end-point switch. The connection information is then interpreted to determine whether the receiving end-point switch is capable of supporting a transparent link. If the end-point network switch is capable of supporting the transparent link, the transparent link is established and utilized to transport data between the sending and receiving parties.

摘要： A system and method for managing data traffic through a path that includes a transmission link having a transport rate that is subject to change with time. In one embodiment the data traffic is shaped to ATM Forum's available bit rate (ABR) category of service. ABR traffic has an integrated resource management (RM) cell that returns congestion related information to the source over a feedback path. With this congestion information the source end point is able to tailor its traffic send or transmission rate in order to accommodate or take advantage of any change in transport rate encountered by the traffic due to dynamically changing rate over the transmission link.

摘要： A method of signalling a message using a terminal address across multiple network entities is provided. At least two contiguous network entities are associated with addressing spaces for which message addresses are not routable by way of the terminal address and are not otherwise routable by way of a single address. The method stores a terminal address of either an originating or terminating network entity. At every network border between any two contiguous network entities wherein an immediately succeeding network entity does not provide an address through which the message is routable, it is determined whether the address is to be stored and replaced with another address. If so, the address is stored so as to permit its subsequent retrieval. Once the address has been stored, the another address is assigned to be the address and the message is routed in the succeeding network using the another address.
