Abstract
Abstract The disclosure relates to a method of monitoring a communications network comprising a plurality of node equipment, eg switches, and link equipment, eg fibre optic links, in which performance parameters of individual components of the node equipment are used to determine an overall performance parameter for the node equipment. By comparing like performance parameters for individual network elements, the performance of different types of network element can be compared with each other. Parameters which can be monitored include quality of service, cell discard, cell loss, and other measures of network performance. The method includes selecting a network element for monitoring (180) using a user interface, selecting a parameter to monitor (182), eg cell discard for the network element, collecting (183) a plurality of data signals describing that parameter, eg in a protocol specific to the network element, and converting the data signals into a generic format independent of the type of network element.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
96 words
A method of monitoring a communications network comprising a
plurality of network elements, each comprising a plurality of components, said
method characterised by comprising the steps of: selecting at least one network element for monitoring (181); selecting an operational parameter of said at least one network element for
monitoring (182); collecting a plurality of data signals from an individual network element, in a
form specific to said individual network element (183); and converting said data signals collected in a form specific to said individual
network element, into a form independent of said individual network element
(184).
Claim 2
Dependent Claim
43 words
A method as claimed in claim 1, comprising the step of obtaining a
plurality of component data signals from an individual network element (185),
each said component data signal containing data describing an operation of a
respective component of the network element .
Claim 3
Dependent Claim
40 words
A method as claimed in claim 2, comprising the step of generating
an element data signal in response to said plurality of component data signals,
said element data signal describing an overall operational parameter of a plurality
of said components.
Claim 4
Dependent Claim
71 words
A method as claimed in claim 2, comprising the step of obtaining
from a first network element a first set of component data signals in a first format
specific to said first network element; obtaining from a second network element a second set of component data
signals in a second format specific to said second network element; wherein said first and second formats are partially or wholly incompatible
with each other.
Claim 5
Dependent Claim
40 words
A method as claimed in claim 4, comprising the step of converting
said first and second sets of component data signals to a common format in
which said first and second component data signals are directly comparable with
each other.
Claim 6
Dependent Claim
121 words
A network monitoring apparatus for monitoring a communications
network comprising a plurality of interconnected network elements, said network
monitoring apparatus characterised by comprising: means for selecting at least one network element for monitoring (10, 24); means for selecting an operation of said at least one network element for
monitoring (10, 24); means (43) for obtaining data signals from said at least one network
element, said data signals containing data describing said selected operation, wherein said means for obtaining data signals from said network element
operates to collect a plurality of data signals from an individual said network
element in a form specific to said individual network element and converts said
data signals into a form independent of said individual network element.
Claim 7
Dependent Claim
21 words
A network monitoring apparatus as claimed in claim 6, wherein a
said operation comprises a performance parameter of said network element.
Claim 8
Dependent Claim
24 words
A network monitoring apparatus as claimed in claim 7, wherein a
said operation comprises a service supported by said at least one network
element.
Claim 9
Dependent Claim
53 words
A network monitoring apparatus as claimed in any one of claims 6
to 8, wherein said means for obtaining data signals operates to obtain a plurality
of component data signals from a said individual network element each said
component data signal containing data describing operation of a respective
component of said network element.
Claim 10
Dependent Claim
50 words
A monitoring apparatus as claimed in any one of claims 6 to 9,
wherein said means for obtaining data operates to generate an element signal in
response to said plurality of component data signals, said element signal
describing an overall operation of said plurality of components of the network
element.
