With such an arrangement, the customer VPN is extended to the gatekeeper of the Call Control Element/router Complex, thereby enabling the provision of voice VPN services over an IP network. | 2009-07-02 |
20090168782 | High-Speed Scheduling Apparatus for a Switching Node - A scheduling apparatus for a switch includes multiple schedulers which are assigned in a variety of ways to non-intersecting control domains for establishing connections through the switch. The control domains are defined by spatial and temporal aspects. The control domains may be dynamically selected and assigned to schedulers in a manner that achieves a high throughput gain. Control domains may be considered in a cyclic and/or a pipeline discipline for accommodating connection requests. The invention enables the realization of a highly scalable controller of a switching node of fine granularity that scales to capacities of the order of hundreds of terabits per second. | 2009-07-02 |
20090168783 | Multi-Protocol Support Over Ethernet Packet-Switched Networks - Described are methods and communications network for carrying pseudowires over packet-switched network. A communication network includes a packet-switched network (PSN), a first provider edge (PE) device in communication with a second PE device through the PSN, and a pseudowire (PW) established between the PE devices for emulating a service across the PSN. The PW has a Virtual Circuit Connection Verification (VCCV) control channel that carries an Ethernet Operations, Administration, and Maintenance (OAM) message. In some embodiments, various data plane encapsulation formats enable a PW to emulate an Ethernet or a non-Ethernet service over an Ethernet PSN. Each encapsulation format includes an Ethernet tunnel header and a PW header that encapsulates an Ethernet or non-Ethernet payload. | 2009-07-02 |
20090168784 | STORAGE SUBSYSTEM - Deadlock is avoided in a grid storage system having superior scalability. Provided is a storage subsystem connected to a host computer for receiving a write or read access from the host computer. This storage subsystem includes a plurality of modules respectively having a storage resource, a switch for connecting the plurality of modules, a controller for controlling the transfer of a packet based on the write or read access from the host computer to a target module among the plurality of modules via the switch, and a memory storing a transfer rule of the packet. The controller controls the transfer of the packet based on the transfer rule. | 2009-07-02 |
20090168785 | MODELING NON-DETERMINISTIC PRIORITY QUEUES FOR EFFICIENT MODEL CHECKING - A method and system are disclosed for modeling non-deterministic queues for efficient model checking. In this method and system, a multitude of messages are held in a plurality of queues, and these messages having n priorities. The method comprises the steps of providing (n+1) queues, including a first queue, and n priority queues; passing said messages from a source to the first queue; passing each of said messages from the first queue to one of said n priority queues based on the priority of the message; and passing each of said messages from the n priority queues to a destination based on the priority of the message. One or more non-deterministic waits are introduced into one or more of the passing steps to simplify passing the messages into or out of the n priority queues. | 2009-07-02 |
20090168786 | DEFINING AN END-TO-END PATH FOR A NETWORK SERVICE - A device receives, from a customer, a request for an end-to-end path through a network, determines parameters of a query based on the request and path criteria, and executes the query on a database of network elements capable of being included in the end-to-end path. The device also selects one or more of the network elements provided in the database based on results of the query, and reserves, in the database, the one or more selected network elements for the end-to-end path. | 2009-07-02 |
