Abstract
A network oscilloscope, including a network interface configured to receive a stream of network data, one or more processors, and a display. The one or more processors generate a timestamp for each data packet parsed from the stream of network data, extract a portion of information from each of the data packets received from the stream of network data, the portion of information being less than an entirety of information in each data packet, and generate a data record indicating extracted information and a timestamp for each data packet parsed from the stream of network data. The display configured to display at least a portion of the data record.
Claims20
A network oscilloscope, comprising:
- a network interface configured to receive a stream of network data;
- one or more processors configured to:
- generate a timestamp for each data packet parsed from the stream of network data,
- extract a portion of information from each of the data packets received from the stream of network data, the portion of information being less than an entirety of information in each respective data packet,
- generate a data record indicating extracted information and a timestamp for each data packet parsed from the stream of network data, and
- arrange the data record based on at least the portion of the extracted information or the timestamp;
- and
- a display configured to display at least a portion of the arranged data record.
A method for use by a test and measurement instrument coupled to a high speed network, comprising:
- receiving a stream of network data, the stream of network data including a plurality of data packets;
- detecting a trigger event;
- determining a timestamp for each data packet received in the stream of network data;
- extracting a portion of information from each of the data packets received in the stream of network data,
- generating a data record, the data record including extracted information and a timestamp for each data packet received in the stream of network data, and
- displaying at least a portion of the data record based on the trigger event.
