<p>A method for retrieving data from a network comprising network elements organised as a multi-level hierarchical tree, each level comprising a set of nodes, the method comprising providing a data exchange interface defining formats for requesting and delivery of types of data to be retrieved; generating a request at the data exchange interface to define the data to be retrieved; using the request to define a canonical name that comprises a series of element names corresponding to at least part of the hierarchical tree containing the network element or elements from which the data is to be retrieved; and a depth indicator indicating the number of levels below the lowest level element name; implementing, at one or more levels in the network, a data retrieval routine that uses the canonical name to generate a command that is issued to the element or elements from which data are to be retrieved to cause the element or elements to return data comprising a description and a value; and communicating the returned data to the data exchange interface in the defined data format.</p> |
