Publication number: 20140075217Abstract: A method and system are provided for reducing power usage in a telecommunications network. An intelligent network manager within a network operations center determines whether to change the power usage of the network, such as reducing power usage at limes of low network activity. The network operations center is in communication with the network elements of the network, and using the communication channels between the network operations center and the network elements the intelligent network manager instructs various ones of the network elements to operate at a lower capacity or even not at all.Type: ApplicationFiled: September 12, 2012Publication date: March 13, 2014Applicant: ALCATEL-LUCENT CANADA INC.Inventors: Kin-Yee Wong, Joseph Rorai

Publication number: 20130329566Abstract: A method and apparatus are provided for determining the power cost of transmitting packets along a specified path. A particular type of OAM packet is transmitted along the path by a first node, and each node along the path adds its power cost of transmitting packets to the OAM packet. Upon reaching the end of the path, the OAM packet is returned to the first node where the power cost of the total path is determined and stored in association with the path.Type: ApplicationFiled: June 7, 2012Publication date: December 12, 2013Applicant: ALCATEL-LUCENT CANADA INC.Inventors: Kin-Yee Wong, Joseph Rorai

Publication number: 20130061072Abstract: A method and apparatus are provided which allow telecommunication equipment to adjust its power consumption. A controller within a telecommunication node uses data to determine whether to reduce the power consumption of components within the node. The data can be real-time data fed to the node or controller, or data read from storage, or both, depending on the particular implementation. Various examples of data and decision-making are given.Type: ApplicationFiled: September 6, 2011Publication date: March 7, 2013Applicant: ALCATEL-LUCENT CANADA INC.Inventors: Kin-Yee Wong, Joseph Rorai

Patent number: 8339995Abstract: The invention is directed to a method and system for providing synchronization clock performance simulation in a timing-over-packet network having a network management system. The system retrieves information from nodes in a network and determines a timing-over-packet topology in a simulated model of the network, and determines clock stability statistics. The system further accepts simulation inputs such as addition or deletion of nodes in the simulated network, or introduction of failures into in the simulated network. The system provides predicted clock stability performance of an existing network under various simulated conditions without requiring modifications or introduction of failures to the existing network which would be useful for network optimization and network planning.Type: GrantFiled: December 10, 2009Date of Patent: December 25, 2012Assignee: Alcatel LucentInventors: Kin Yee Wong, Peter Roberts

Publication number: 20120173660Abstract: A method and apparatus are provided in which a new input to a telecommunications node is provided, namely the real-time cost of power. By providing this information, the node may make more informed decisions as to power cost of various options. For example, the node may alter its operating parameters based on the current cost of power to implement various features. The real-time cost of power is provided to the node by the power provider. The real-time cost of the power is provided to the node using any method, such as by packets through a dedicated interface of the node, packets through a UDP port, or as packets over the electricity grid. The telecommunications node is just one example of end user equipment, and the real-time cost of power may be provided to any power-consuming equipment.Type: ApplicationFiled: January 4, 2011Publication date: July 5, 2012Applicant: ALCATEL-LUCENT CANADA INC.Inventors: Joseph Rorai, Kin-Yee Wong

Publication number: 20120173889Abstract: A method and apparatus are provided which allow telecommunication equipment to adjust its power consumption. By replicating the functionality of a standard component for processing traffic on a general purpose CPU, traffic can be routed within the equipment to the general purpose CPU for processing instead of the component under certain conditions. If the maximum bandwidth supported by the functionality on the general purpose CPU is less than the maximum bandwidth supported by the component, then the component can be powered down during times of low traffic and the traffic routed to the general purpose CPU instead. Since the maximum bandwidth supported by the functionality on the general purpose CPU is less than the maximum bandwidth supported by the component, less power is necessary to operate the telecommunication equipment and hence cost is reduced.Type: ApplicationFiled: January 4, 2011Publication date: July 5, 2012Applicant: ALCATEL-LUCENT CANADA INC.Inventors: Kin-Yee WONG, Joseph RORAI

Patent number: 7376224Abstract: A system and method are provided for enabling additional capacity or features on telecommunication nodes without requiring replacement of hardware. Service providers purchase hardware which is fully capable of providing a full suite of features and providing a large bandwidth capacity. However, depending on the amount of payment by the service provider, not all of the features or the bandwidth capacity is enabled. If the service provider wishes to increase the number of features or the capacity of a node, the additional features or capacity are enabled using software after payment to the vendor. This allows service providers to enter the market at an initially relatively low expense. Additional features and capacity can be purchased and enabled using software as demand grows, without having to purchase replacement hardware.Type: GrantFiled: February 4, 2004Date of Patent: May 20, 2008Assignee: Alcatel LucentInventor: Kin Yee Wong

Publication number: 20040255202Abstract: Method and apparatus providing intelligent fault recovery are presented. The apparatus includes line card equipment separating control plane components from data plane components enabling a control plane reset while the data plane remains operational at least to the extent that content conveyed in respect of currently provisioned services continues to be processed therethrough. Detected faults are categorized in accordance with a group of severity levels and recovery behavior is specified for each fault severity level. As a guiding principle of the engineered failure mitigation response provided, the control plane of a fault affected line card is reset in an attempt to mitigate an experienced fault condition; the entire line card being reset only as a last resort and only to restore service.Type: ApplicationFiled: June 13, 2003Publication date: December 16, 2004Applicant: AlcatelInventors: Kin Yee Wong, David George McKay, Joseph Graham Rorai
