AI Technical Summary

Benefits of technology

The system efficiently recognizes and correlates transaction occurrences, including variations, without manual intervention, by characterizing transactions as regular expressions, enabling the identification of new occurrences and simplifying the matching process through unique identifiers and normalization.

Problems solved by technology

These variations are often difficult to account for because, though the number of distinct transactions is typically small, the number of transaction occurrence variations can be virtually unlimited.
Accordingly, it is often impractical to manually correlate each variation back to its corresponding transaction.

The Apparatus Configuration

[0034] An apparatus configuration according to the present invention is depicted in FIGS. 1 and 2 for analyzing the performance of a computer network such as by measuring the response time required for a transaction to be performed. FIG. 1 depicts a simple single network segment wherein the term “segment” denotes a portion of a network having at least two network nodes and the network connections therebetween. In the network of FIG. 1, a recording device or probe 20 is connected to a communication line or busline 24 between a client (or user) computer 28, and a server computer 32 (i.e., a server). The recording device 20 selects one or more informational packets in each service request that is transmitted along the communication line 24 and provides the informational packets and the time at which the packets were received by the recording device 20 to the monitoring computer 36 for analysis. In particular, the informational packets selected provide the r...

Abstract

The present invention is directed to a method and apparatus for identifying occurrences of transactions, especially in computer networks. A unique identifier, denoted “request identifier”, is associated with each service request. Accordingly, for a sequence of service requests detected, a corresponding sequence of request identifiers is generated. The request identifier sequence is compared to regular expressions that correspond to different transactions. If the request identifier sequence matches a regular expression, this sequence is deemed to represent an occurrence of that transaction.

Description

TECHNICAL FIELD OF THE INVENTION [0001] The present invention is directed generally to a method and apparatus for recognizing and predicting transactions and particularly to a method and apparatus for recognizing and predicting transactions using regular expressions from formal language theory. BACKGROUND OF THE INVENTION [0002] In computer networks, “information packets” are transmitted between network nodes, wherein an informational packet refers to, e.g., a service request packet from a client node to a server node, a responsive service results packet from the server node to the client node, or a service completion packet indicating termination of a series of related packets. Server nodes perform client-requested operations and forward the results to the requesting client nodes as one or more service results packet(s) containing the requested information followed by a service completion packet. A “service request instance,” or merely “service request” refers to a collection of su...
