Abstract

A system and method of logging multicast data messages in a communication network implement data logging methodologies mapped onto a multicast architecture exploiting the efficiencies inherent in multicasting techniques. A multicast logging system may include one or more Log Clients publishing log reports to one or more multicast addresses, one or more Log Servers subscribing to one or more multicast addresses and persisting selected log data, and a Log Viewer presenting a real-time view of log traffic directed to one or more multicast addresses. A method of logging multicast messages may incorporate such a system arrangement. Additionally, alarm messages comprising critical system data may be multicast using the foregoing system architecture and functionality.

18. A computer readable medium encoded with data and computer executable instructions for transmitting a log report, the data and instructions causing an apparatus executing the instructions to:

produce a log report for publication to one or more multicast subscribers;

said log report containing data to be logged;

selectively implement reliable multicast transport techniques; and

multicast said log report to said one or more multicast subscribers in accordance with said multicast transport techniques.

19. The computer readable medium of claim 18 further encoded with data and computer executable instructions, further causing an apparatus to receive a request for reliable data transmission from an application producing said log report.

20. The computer readable medium of claim 18 further encoded with data and computer executable instructions, further causing an apparatus to receive a request for reliable data transmission from said one or more multicast subscribers.

21. The computer readable medium of claim 18 further encoded with data and computer executable instructions, further causing an apparatus to:

transmit said log report a log viewer; and

request said log viewer to display information related to said log report.

22. A multicast logging system comprising:

a log client publishing log data to one or more multicast addresses on a communications network; and

a log viewer subscribing to at least one of said one or more multicast addresses and allowing reception and display of information related to said log data.

23. The system of claim 22 wherein said log client publishes said log data without using reliable multicast transport techniques.

24. The system of claim 22 wherein said log client comprises a computer executable program application generating said log data.

25. The system of claim 22 wherein said log viewer comprises a console application.

26. The system of claim 25 wherein said log viewer is incorporated into a World Wide Web browser application.
