Patent number: 8488476Abstract: System and method for providing applets to remote devices in a communications network. A preferred embodiment includes a host device, which is the device from which the applet will be transferred, and a target device, which is the device to which the applet will be transferred. In one embodiment, the host device autonomously determines that an applet is to be pushed to the target device. The host device then determines the address of the target device and transmits the applet to the target device. Instructions and commands may be sent to the target device form the host, and the target device may transmit results to the host device. In another embodiment, the target device is customer premise equipment and/or a user device that requests an applet from the host device. The target device requests applets, for example, to perform service parameter verification, performance monitoring, troubleshooting, or the like.Type: GrantFiled: June 2, 2004Date of Patent: July 16, 2013Assignee: Verizon Business Global LLCInventors: Nick DelRegno, Scott R.

Patent number: 8289973Abstract: System and method for providing a layer 2 switch in the access network that switches based upon one or more carrier tags identifying customer traffic. Customer traffic conforming to any variety of different layer 1 or layer 2 protocols may be encapsulated and identified according to carrier tag values. The layer 2 switch may determine how to handle the traffic by interpreting and manipulating the carrier tag values. The layer 2 switch may be capable of switching TDM input traffic to either TDM or packet output traffic, and switching packetized input traffic to either TDM or packet output traffic. Handling classification values may also be processed by the layer 2 switch to affect prioritization of handling of encapsulated traffic.Type: GrantFiled: June 3, 2004Date of Patent: October 16, 2012Assignee: Verizon Business Global LLCInventors: Nick DelRegno, Scott R.

Patent number: 8218569Abstract: System and method for providing a termination point for service emulation instances in an access network is provided. In an embodiment, the service emulation instances are implemented utilizing, for example, pseudowires. Communications to and from the access network are aggregated and transmitted via one or more pseudowires to a service emulation instance terminator. The service emulation instance terminator converts the traffic to its native form and, if necessary, converts the traffic to a different type of format or service. The service emulation instance terminator then frames the traffic for the appropriate type of service and transmits the traffic to the service edge. Traffic received from the service is removed prepended with a pseudowire label and aggregated with other traffic. The aggregated traffic is transmitted to the customer via the access network. If necessary, an interworking function may convert the traffic from one type of service to another type of service.Type: GrantFiled: June 1, 2004Date of Patent: July 10, 2012Assignee: Verizon Business Global LLCInventors: Nick DelRegno, Scott R.

Publication number: 20120170467Abstract: An approach provides virtual circuit protection. Traffic is received at a network interface device configured to interface an Ethernet virtual circuit of a service provider transport network over a user network interface (UNI). The network interface device is configured as a demarcation point between a customer network and the service provider transport network. Circuit replication is performed over the virtual circuit to create a plurality of communication paths over the virtual circuit by assigning respective tags for independently switching the traffic over the communication paths. One of the communication paths is designated as a standby communication path.Type: ApplicationFiled: December 29, 2010Publication date: July 5, 2012Applicant: VERIZON PATENT AND LICENSING INC.Inventors: Michael U.

Publication number: 20120127993Abstract: An approach is provided for auto-bandwidth adjusting bandwidth allocations for traffic-engineered tunnels used to carry traffic along a network. Traffic over the tunnel is sampled at a first interval period and at a second interval period, where the second interval period is shorter than the first interval period. A determination is made as to whether the sampled traffic taken using the second interval period is greater than the bandwidth allocation, and the bandwidth allocation is adjusted upward based upon a determination that the sampled traffic taken using the second interval period is greater than the bandwidth allocation. Also, a determination can be made as to whether the sampled traffic taken using the first interval period is less than the bandwidth allocation, and the bandwidth allocation can be adjusted downward based upon a determination that the sampled traffic taken using the first interval period is less than the bandwidth allocation.Type: ApplicationFiled: January 30, 2012Publication date: May 24, 2012Applicant: Verizon Corporate Services Group Inc.Inventors: Matthew W.

Patent number: 8159968Abstract: A system measures, at a network device, a first frame rate of frame-based transport based on a first frame size, and measures, at the network device, a second frame rate of the frame-based transport based on a second frame size, where the second frame size is different than the first frame size. The system determines per frame encapsulation overhead in the frame-based transport using the first frame rate, the first frame size, the second frame rate, and the second frame size. The system further determines total transport bandwidth associated with the frame-based transport using the first frame rate, the first frame size, the second frame rate, the second frame size, and the determined per frame encapsulation overhead.Type: GrantFiled: December 8, 2009Date of Patent: April 17, 2012Assignee: Verizon Patent and Licensing, Inc.Inventors: Scott R.
