Method, apparatus and system for monitoring network conditions via a stacked topology of network captured traffic distribution devices

Abstract

Methods, systems, computer-readable media, and devices for monitoring a stacked topology of network captured traffic distribution devices and / or a device or network connected thereto are described. For example, a network captured traffic distribution device communicatively coupled to a plurality of network captured traffic distribution devices arranged in a stacked topology via a communication link may monitor a status of the stacked topology, a network captured traffic distribution device included in the stacked topology, a network communicatively coupled to the stacked topology, and / or a network device communicatively coupled to the stacked topology. Configuration information included in the network captured traffic distribution device may be updated responsively to the monitoring.

Description

RELATED APPLICATIONS[0001]This application is a NONPROVISIONAL of, claims priority to and incorporates by reference U.S. Provisional Patent Application 61 / 248,837, filed 5 Oct. 2009.FIELD OF THE INVENTION[0002]The present invention relates to methods and systems for monitoring a stacked topology of network captured traffic distribution devices and / or a device or network connected thereto.BACKGROUND[0003]Traditionally, network traffic is captured locally using a mirror port present on a network switch or a network tap in conjunction with an inline traffic capture point positioned along a communication link coupling two or more communicating devices. Network traffic captured in this way is typically monitored locally, thus requiring a port on a monitor for every individual capture point and mirror port in the network. This localization leads to great infrastructure and bandwidth costs and, consequently, many networks are inadequately monitored.[0004]Another drawback to traditional net...

AI Technical Summary

Benefits of technology

The patent describes a system for monitoring network traffic and detecting changes in the distribution of network devices. The system includes multiple network captured traffic distribution devices that communicate with each other through a communication link. The devices can detect changes in the network traffic, such as congestion or a breach of security, and adjust their configurations accordingly. The system can also analyze the network traffic to identify patterns and trends, and provide information on the network's operational status. The technical effects of the patent include improved monitoring and analysis of network traffic, as well as improved resilience against unauthorized intrusions.

Problems solved by technology

Exemplary detected changes include a communication link failure, a failure of the network captured traffic distribution device, a security breach, a suspected denial of service attack, a power failure, the addition of a network captured traffic distribution device to the stacked topology, the removal of a network captured traffic distribution device from the stacked topology, and a change in the status of a network device communicatively coupled to the stacked topology.
