The amount of raw data gathered is usually quite large, typically ranging somewhere between several megabytes to several gigabytes of data each month.

This document defines a model and protocol for a set of tools which could be used by NSPs and Network Operation Centers (NOCs) to share data among themselves and with customers.Network administrators gather data related to the performance, utilization, usability and growth of their data network.The primary goal of gathering the data is to facilitate near-term problem isolation and longer-term network planning within the organization.From this raw data, the network administrator produces various types of reports.This document defines a protocol which would allow a client on a remote machine to retrieve data from a central server, which itself retrieves from the common statistics database.

The client then presents the data to the user in the form requested (maybe to a X- window, or to paper).

The basic model used for the retrieval methods defined in this document is a client-server model.

This architecture envisions that each NOC (or NSP) should install a server which provides locally collected information for clients.

Using a query language the client should be able to define the network object of interest, the interface, the metrics and the time period to be examined.

Using a reliable transport-layer protocol (e.g., TCP), the server will transmit the requested data.

Once this data is received by the client it could be processed and presented by a variety of tools including displaying the data in a X window, sending postscript to a printer, or displaying the raw data on the user's terminal.
