Maintaining historical LAN traffic statistics
First Claim
1. A method for collecting and displaying statistical data for a plurality of local area networks, said process comprising the steps of:
- (a) collecting the statistical data in a plurality of remote computer systems, one computer system connected to each of the plurality of local area networks;
(b) transferring the statistical data from each of said remote computer systems to a management node computer system; and
(c) receiving, assembling, storing, compressing and displaying the statistical data in said management node computer system wherein said compressing compress the steps of(c1) combining samples having different sample intervals, and(c2) estimating a new peak value for samples having a new sample interval wherein said estimating comprises the step of computing the following formula
space="preserve" listing-type="equation">new-peak=(total-old-peak)*(NSI-OSI)+old-peak P-OSI.

Abstract
Disclosed is a system for collecting and displaying statistical data for a plurality of local area networks (LANs). The data is collected in several remote nodes, each of which is attached to a local area network. The data is obtained by using a LAN driver that intercepts all records on the LAN. The records are sent to a collector process where statistics are accumulated into a shared memory area and then transferred to an archiver process in a management node. The archiver process writes the statistics to a history file while compressing older data to prevent the file from growing too large. The file is compressed based on a table of compression schedules, and peak data from samples having varying sampling rates is combined by reducing all sampling rates to the same value and estimating the peak data for samples wherein the sampling rate is changed.

11. A system for collecting and displaying statistical data for a plurality of local area networks, said system comprising:
-
means located in a plurality of remote computer systems, one computer system connected to each of the plurality of local area networks, for collecting the statistical data; management node means for assembling, storing, and displaying the statistical data; means located in each of said remote computer systems for transferring said statistical data to said management node computer system; and means located in said management node for receiving said statistical data transferred from each of said remote computer systems and for compressing said statistical data wherein said compressing comprises means for combining samples having different sample intervals, and means for estimating a new peak value for samples having a new sample interval, comprising means for computing the following formula
