Systems And Methods For Definition And Use Of A Common Time Base In Multi-Protocol Environments
View pageUS Patent:
7804852, Sep 28, 2010
Filed:
Jan 23, 2004
Appl. No.:
10/764095

US Classification:
370469, 375356, 713400, 714 39
Abstract:
Systems, device and methods are provided for determining a reference clock frequency for use by a multi-protocol analyzer in connection with a multi-protocol communications system. Initially, the clock frequencies for each of the links in the multi-protocol communications system are determined. The link clock frequencies are then used as a basis for determining the frequency of the reference clock. While the reference clock frequency is based upon the link clock frequencies, the reference clock frequency is different from each of the reference clock frequencies.

7844690, Nov 30, 2010
Filed:
Jan 23, 2004
Appl. No.:
10/764059
Inventors:
Douglas Durham - Sunnyvale CA, US
John Arrington - Belmont CA, US
Dominic Coupal - Santa Clara CA, US

Dominic Coupal - Santa Clara CA, US
International Classification:
G06F 15/173
US Classification:
709223, 709220
Abstract:
Systems and methods are provided for facilitating analysis of a communications system through the use of a multi-protocol communications analyzer. A graphical user interface employed in connection with the multi-protocol communications analyzer enables a user to create a new domain, or modify an existing domain, that includes a list of ports selected by the user, where each port is associated with a particular communication link of the communications system. The ports are selected from a list of available ports displayed by the graphical user interface. The ports selected for inclusion in the domain can then be configured, by way of the graphical user interface, as desired. After the domain has been defined, the domain can then be used to analyze one or more of the links associated with the ports included in the domain.

International Classification:
G06F 9/44
G06F 15/16
G06F 15/16
US Classification:
719318, 709224
Abstract:
Systems, device and methods are provided for displaying time sorted data events captured in a multi-protocol communications system. Initially, data events are captured in connection with detection of one or more trigger conditions, and each captured data event includes a clock timestamp. The captured data events are then sorted and displayed by a graphical user interface according to their respective clock timestamp. Once the data events have been sorted and displayed, then the temporal relationships and causal relationships, if any, between and among the captured data events can be determined.

Filed:
Oct 24, 2001

International Classification:
G06F011/00
US Classification:
714 39, 715530, 709230
Abstract:
Presently preferred embodiments of the current invention are directed to a protocol analyzer for interpreting data frames captured on a communications network. The protocol analyzer includes a network interface connection for providing the electrical and physical connection to the communications network and for receiving data frames from the network in a particular physical layer protocol format. The protocol analyzer further includes analysis software for providing an interpretation of received data frames. The interpretation of a frame is based upon a series of definition constructs that are stored in a protocol definition file and a protocol database of the protocol analyzer. The definition constructs collectively define the characteristics of a data frame for a given physical layer protocol. Also, the constructs provide a means for identifying any one of a number of higher level protocols that may be embedded within the data frame. Also disclosed is a graphical user interface for use as a protocol editor for assembling the necessary definition constructs for inclusion in a protocol definition file.
