A method for storing a plurality of packets includes receiving a packets from a network, applying a hash function to values of one or more fields in the packet so as define a hash key and to select a storage bucket from a plurality of buckets, and adding the packet to the storage bucket. A bucket record associated with the storage bucket includes a flow index determined based on the values of the one or more fields in the packet.

Method and system for storing packet flows

The invention relates to a method and apparatus for efficient storing and retrieval of captured data packets. The packets are parsed to extract flow defining parameters such as source and destination addresses, the extracted addresses are hashed and the address hash numbers are reversibly combined, for example concatenated in a pre-defined order of their values to obtain a single hash index for a flow. The packets are then saved in a packet store in accordance and/or association with their hash index. The packets may be efficiently retrieved based on the two addresses or on a single network address.

Hashing of network packet flows for efficient searching

A system or method that extends a communication test/measurement agent by providing the communication test/measurement agent with built-in functionality to allow a central communication test/measurement system to generically communicate with and operate the agent, and by providing the communication test/measurement agent with built-in functionality to allow the agent to automatically recognize and dynamically incorporate plugins that are specific to different types of communication interfaces and which allow the network test/measurement system to communicate with the respective different types of communication interfaces.

Methods and systems for assigning participant identifying data to network transmission events. Participant identifying data and identifying data related to a network transmission event are provided to a predetermined (also referred to as central) monitoring location and stored in a database at the central monitoring location.

Systems and methods for collecting and disbursing participant identifying data

Methods and systems for coordinated monitoring of network transmission events. Predetermined information for the network transmission event is obtained at a first network location and the network transmission event predetermined information is provided to a predetermined monitoring location (or server). From the predetermined monitoring location, the predetermined information is provided to other network monitoring devices at one or more other network locations. At the one or more other network locations, the network transmission event, corresponding to the predetermined information obtained at the first location, is monitored. Network transmission event information, corresponding to the predetermined information obtained at the first location, is provided to the predetermined monitoring location from the first location and the other network locations. The monitoring of network transmission can be thereby coordinated.

Methods and systems for coordinated monitoring of network transmission events

Systems and methods are provided for the management and analysis of detail records in a mobile telephony network, including the ability to store remotely and retrieve detail records given a specific call or a data session for signaling analysis in such networks. Computer program products which can execute such methods are also provided.

Tools, methods and systems of storing remotely and retrieving detail records given a specific call or data session

Network analyzing systems and methods are disclosed herein for analyzing a segment of a data communications network. One example of a network analyzing system includes a network analyzer that comprises a frame monitoring device operative to detect frames on the network segment under analysis. The network analyzer further comprises a frame decoder for decoding the frames to provide decode information that is stored on a decode information buffer. A display generating system is operative to create a graphical display view from a portion of the decode information. The graphical display view may be displayed in a graphical user interface of a display device.

A packet data capture apparatus, method and a computer readable medium having instructions recorded thereon, stream data packets in real time. The apparatus includes: a buffer, to store a plurality of data packets until transmission; a macro-packet transmitter, to prepare macro-packets from the stored plurality of packets and operate in a UDP mode that includes a predetermined re-transmit and flow control protocol; and a processor, to stream the macro-packets to a computer/server or storage device in real time and to retransmit respective macro-packets of the stream of macro-packets via the re-transmit and flow control protocol in accordance with a request from the computer/server.

High speed acquisition system that allows capture from a packet network and streams the data to a storage medium

Inflowing data is summarized in real time. The summarized data is displayed as a graph in real time. A portion of the graph is selected using dual sliders. And data that was summarized in real time and represented by the selected graph portion is operated on. Operating on the data that was summarized in real time and represented by the selected graph portion involves displaying components of the data that was summarized in real time and represented by the selected graph portion and/or exporting the data that was summarized in real time and represented by the selected graph portion. Displaying components of the data that was summarized in real time and represented by the selected graph portion involves displaying components of the data that was summarized in real time in one or more new graphs and/or displaying components of the data that was summarized in real time in tabular form.
