DATA RETRIEVAL IN A NETWORK OF TREE STRUCTURE
First Claim
1. A method for retrieving data from a network comprising network elements organized 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 definea 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 a number of levels below a 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 network element or elements from which data are to be retrieved to cause the network 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;
wherein the network does not include a management information base, data being returned to the data exchange interface from the elements in a self-explanatory format without passing through a management information base.

Abstract
A method for retrieving data from a network having network elements in a multi-level hierarchical tree includes 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 and a depth indicator, 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 including a description and a value, and communicating the returned data to the data exchange interface in the defined data format.
