摘要:
The invention relates to a method for evaluating the bandwidth between a first point and a second point liable to exchange digital data packets in a telecommunications network including a plurality of sub-networks. The method according to the invention includes the following steps: for each transmission direction through at least one of said sub-networks, associating a same identifier with the quasi-simultaneously transmitted packets, time-stamping and recording the received packets, identifying and sorting the packets received with the same identifier, selecting the largest possible integral number m of groups of packets with the same identifier, measuring the time intervals separating the instants when the packets of the selected groups are received by the second point, calculating the bandwidth according to the number of packets of the selected groups and to said total transmission time of said packets.

A device for checking a transmission line carrying a plurality of digital and/or analogue transmission channels is provided. The device includes a measurement block designed to evaluate performances, search for faults and determine the quality of the line and services transmitted through the said line. A system for measuring disturbances is also provided. The system measures disturbances in a transmission line firstly connecting a subscriber to a high speed server through an xDSL modem, and secondly to a switched telephone network.

Method for distributing hardware and software resources for testing links between a plurality of subscriber devices and a telecommunications operator in a telecommunications network, comprising: a central control site (2), at least one intermediate connection site (4), connected on the one hand to the central site (2) by a first transmission line (3), and on the other hand to the subscriber devices (12) by a second transmission line (13). This method is characterised by the following steps: defining the tests to be performed on the first line (3) and the tests to be performed on the second line (13), distributing said hardware and software resources between said central site (2) and said intermediate connection site (4) depending on the tests likely to be performed on the first transmission line (3) and on the second transmission line (13) respectively.
摘要:
The invention relates to a device for checking (1) a transmission line carrying a plurality of digital and/or analogue channels comprising a measurement block (14) designed to evaluate performances, search for faults and determine the quality of the line and services transmitted through the said line. According to the invention, the device also comprises a switching module (16) capable of selectively connecting the measurement block (14) only to the transmission channels to be checked and to keep other channels in the transmission line active.
摘要:
The invention concerns a non intrusive control process of an xDSL transmission line from signals and messages exchanged between at least one emitter (1) to at least one receiver (2) at the end of or during a predefined handshaking procedure.This process comprises the following steps:a1. Analysing the type of signals exchanged between the emitter (1) and the receiver (2) during the establishment of the new contact,b1. Establishing a diagnosis on the state of the line according to the result of step b1.

The invention relates to a monitoring system and method for performing a connectivity check and a trace routing test in Ethernet based networks built around VLAN switching. For the connectivity check, a beacon frame is inserted at an originating point by an initiating test unit for transmission to a destination point provided with a loop for returning a response frame to the initiating test unit whenever the beacon frame is received, thereby confirming connectivity between the originating and destination points. For the trace routing test, a marker frame is inserted at the originating point by the initiating test unit and monitored as it passes through network nodes along its way towards the destination point. At any node where the beacon frame is detected, a tracing frame containing a copy of the marker frame is returned to the initiating test unit to build a sequential list of every node where the marker frame is detected.
摘要:
Systems and methods for analyzing the consumption of transmitted audio visual content are disclosed. The methods may comprise analyzing content viewed by consumers and updating the profiles of that content and/or the consumers accordingly, such as a method for analyzing the consumption of AV content by consumers comprising: assigning to each AV asset a tag comprising a unique asset ID and a multiple-entry asset qualification tag; assigning to each consumer a multiple-entry consumer qualification tag; and assigning to a consumer a new consumer qualification tag that is derived from a weighted combination of an existing consumer qualification tag associated with the consumer and an asset qualification tag of a selected AV asset, the consumer having requested the selected AV asset. The systems may comprise appropriately configured computing hardware, software, and connectivity for performing such methods, such as a calculation component configured to determine a new tag value for a consumer qualification tag associated with a consumer based on a weighted combination of a current tag value of the consumer qualification tag and a tag value of an asset qualification tag associated with an AV asset, the AV asset having been requested by the consumer; and a consumer qualification tag update component configured to set the tag value for the consumer qualification tag to the new tag value.
