Problems solved by technology

Between frames, however, data transfer is limited by the number of cables interconnecting the boxes
Thus, it becomes a complex task to coordinate the actions of multiple ports interconnected in multiple domains on multiple sheets over multiple frames
This coordination becomes more difficult when the analyzer examines multiple channels

Embodiment Construction

[0031] Generally, embodiments of the present invention relate to a system in which each multi-protocol analyzer frame or box with a separate page and port is serially linked together to allow data to be captured from multiple ports in the domain, so The domain may extend across the frame of the serial connection. Specifically, the present invention relates to the "normal mode" part of the system, through which the serial protocol is used to transfer running, stopping and triggering data between the network protocol frameworks of the serial connection. Through the use of the serial protocol, the number of lines connecting the frame can be minimized, and each page across the frame can be simultaneously started, stopped, and triggered simultaneously to capture the network data of interest synchronously.

[0032] The related embodiments and sync-groups of operating the protocol analyzer framework in the "discovery mode" to discover and configure multiple ports on one or more framework...

Abstract

Protocol analyzers systems and methods coordinate the capture of network data of interest across multiple chassis. Each chassis has individual blades with accompanying ports and is serially connected to other chassis in the system. Selected ports from each chassis are configured in domains that can be spread across the serially connected chassis and used in coordination to capture network data of interest. A serial protocol containing control signals is used to transmit run, stop, and trigger data between the serially connected chassis and thereby coordinate the activity of ports within each domain. Through the use of the serial protocol the number of wires connecting adjacent chassis is minimized and each of the blades in the multi-chassis systems can be synchronously started, stopped, and triggered at the same time to synchronously capture the network data of interest.

Description

[0001] Cross references to related applications Technical field [0002] The present invention generally relates to a multi-channel high-speed communication system, method and device for analyzing communication services. More specifically, the embodiments of the present invention relate to systems and methods for coordinating the operations of various chassis, blades, ports, and analyzers in a multi-frame protocol analyzer system. Background technique [0003] Due to declining costs, improved performance of computers and networking devices, and increased demand for communication bandwidth, computer and data communication networks continue to develop and expand. Communication networks include, for example, wide area networks (WAN), local area networks (LAN), and storage area networks (SAN), which allow increased productivity through resource sharing, voice and data transfer, and processing of voice, data, and related information in the most efficient location And the use of distrib...
