摘要:
A system, method, and network node (14) for distributing a network management task from a source to a plurality of network nodes in a traffic network (10). When a task is received in a network node (14), the node determines whether the task is to be forwarded to other network nodes. If so, the receiving network node utilizes application-level knowledge of the functionality of each neighboring node to select one or more neighboring nodes that need to receive the task. The receiving network node then utilizes a functional management overlay layer (12) known as the Data Discovery and Distribution, D3, layer to communicate the task to the selected neighboring nodes. The network node receives responses from the neighboring nodes, aggregates the responses with local information, and sends an aggregated response to the source.

Techniques are described for managing traffic flow to an optical network terminal (ONT) on a passive optical network (PON) to prevent an individual ONT from being overrun. Specifically, the techniques involve reducing a transmission rate of a unique traffic flow and selectively denying access to a common traffic flow. By reducing the transmission rate of the unique traffic flow, sufficient bandwidth may be released to receive the unique traffic flow and the common traffic flow without overflowing the ONT. For example, the ONT or, alternatively, the OLT may send the requested common traffic flow without reducing the transmission rate of the unique traffic flow when sufficient bandwidth is available, send the common traffic flow but reduce the transmission rate of unique traffic flow by an appropriate amount, or deny access to the common traffic flow altogether without reducing the transmission rate of the unique traffic flow.

In general, techniques are described for efficient management of ring networks with a system of two network devices. The first network device of the ring network is designated as an adjacent selective forwarding (ASF) device, and the second network device is designated as a master device. The master device monitors the ring network to determine whether a fault has occurred in the ring network and transmits via a secondary port of the master device a network status message to the ASF device based on the determination of whether the fault has occurred. The ASF device determines a status of the ring network based on the network status message and selectively forwards data traffic to the master network device based on the determination of the status. As a result, the master device more efficiently utilizes network resources by not consuming processor or memory resources to prevent traffic loops.
摘要:
A method for managing the configuration of a telecommunications network, the method comprises remotely creating a data file containing attributes of managed objects for one or more network elements of the network, uploading the data file to a management system of the network, inspecting the data file and identifying managed objects having attributes which have been created, varied or deleted, producing a database of the identified managed objects and the values thereof, and analysing the data in the database to manage the configuration of the telecommunications network accordingly. Also disclosed are an apparatus for performing the method, a management system incorporating the or apparatus and a telecommunications network incorporating the management system.
摘要:
A method for use in management of network elements in a communications network performed by a network element of said network. The method comprises receiving by an agent operating in said network element a request to execute a first function, wherein said first function relates to management of at least one network element; sending to said first function a message corresponding to said request and executing said first function. Said request being from a predefined set of requests and said first function being from a predefined set of functions. Said first function is implemented in a network element where it is to be executed.

摘要:
The invention is directed to techniques for reducing power consumption by an optical network transmitter (ONT) in a passive optical network (PON). The techniques may be particularly useful in extending the period of battery powered telephone service during a power outage. In particular, the invention provides a hibernation mode in which power is supplied only to a watchdog circuit while the ONT powers down the optical transmitter, the optical receiver, processing circuitry, data circuitry, video circuitry, and telephone circuitry to conserve power. The watchdog circuit wakes up a subset of the deactivated circuitry at service-critical events in order to service such events, but video and data processing circuitry remain deactivated.

Accelerated heating of automotive exhaust system components is effected by controlling the application of supplemental electrical loads to the vehicle electrical system thereby increasing engine load and increasing exhaust heat. Alternative strategies are disclosed for implementing the invention through control of electrical and engine management system parameters.
摘要:
A method of operating a home-based network device, wherein said home-based network device is part of a telecommunications network. The method comprising the steps of: assigning an address to the home-based network device, wherein said address is a function of a public identity of a subscriber associated with said home-based network device. The method further comprising registering the address of said home-based network device in an addressing space containing addressing information of other home-based network devices and providing access said home-based network device to users that are not associated with said home-based network device.
