Protocol analyzer for monitoring digital transmission networks
First Claim
Patent Images
1. A protocol analyzer for calculating and displaying protocol distribution in real-time in connection with monitoring data frames carried on a digital transmission network, comprising:
- means for monitoring the transmission, over the digital transmission network, of frames containing data and protocols;
means for identifying the protocols within the frames and for identifying the encapsulation of the protocols within the frames;
means for storing the identity and encapsulation of the protocols within the frames;
means for calculating the protocol distribution of the frames; and
means for displaying in real-time the protocol distribution of the frames in a hierarchical tree format based upon the encapsulation of the protocols within the frames, said means comprising;
a first processing instrumentality, comprising means for periodically requesting a protocol distribution update message containing encoded updated protocol distribution information from said means for calculating the protocol distribution of the frames;
a second processing instrumentality, having;
a. means for receiving and decoding the protocol distribution update message to obtain the updated protocol distribution information, andb. means for providing said first processing instrumentality with a pointer to the updated protocol distribution information;
a display device for displaying the updated protocol distribution information; and
a third processing instrumentality, having;
a. means for obtaining a pointer to the updated protocol distribution information from said first processing instrumentality, andb. means for sending the updated protocol distribution information to said display device in a hierarchical tree format based upon the encapsulation of the protocols within the frames.

Abstract
A new and improved protocol analyzer for monitoring digital transmission networks is disclosed. The protocol analyzer of the present invention is capable of displaying station level statistics, network statistics, real-time event information, and protocol distribution. The protocol analyzer of the present invention is additionally capable of creating baseline network performance information and displaying the baseline information simultaneously with real-time performance information, pre-programming monitoring sessions, and generating presentation-quality reports in conjunction with analyzing digital transmission networks, all in real time.
