Capturing of network traffic passing through the NIC (Network Interface Controller) is performed by using a special filter driver that is installed in the NDIS (Network Driver Interface Specification) driver stack. This allows data frames to be captured starting from the Data Link Layer - Layer 2 of OSI (Open Systems Interconnection) model. Such application architecture allows capturing of all network packets passing through the adapters, including transit network packets. To overcome limitation of the Ethernet frame size set by IEEE 802.3 we support jumbo frames that are widely used, for example, in PPPoE networks.
For each running monitoring session, a corresponding session is created in the filter driver, captured data is stored in buffer until the application picks it up. Transport layer packets (for example TCP or UDP packets) are identified according to processes running in the operating system, their PIDs are transmitted to visualizers and then shown to the user, facilitating the identification of analyzed network traffic.
All the data extracted from filter driver is sent to application for further processing. Then data is parsed at the application level by binding different structures (defined in .h files) to the specific packet's offsets. This is the way network packets are parsed at the Data Link Layer (for example ARP, PPP, Ethernet packets), Network Layer (for example IPv6, IPv4 packets), Transport layer (TCP, UDP), Session Layer, Presentation Layer and Application Layer. Thus, using our product you always have a complete trace of structured data at the full depth of encapsulated protocols.

This approach makes our product, in fact, the only nonintrusive software network protocol analyzer available on the market today.
Our network analyser offers advanced protocol-based filtering feature, which allows you to create and configure network packets filtering schemes and quickly apply them to visualizer windows and even data exporting modules. The filters are optimized for high performance, allowing on-the-fly filtering without affecting the monitored communication.
Additionally, you may change the appearance of visual elements for monitored packets in the data visualizers including Structure View, Raw Data View, HTTP View and Custom View. No other solution will allow you to adjust your output as flexibly and conveniently as our product.
Our product is the only one among all other network traffic monitoring software, which offers you the opportunity not only to snoop the TCP/IP & UDP communications in real time, but also to record the network data in the log file with the possibility to replay and analyze it later or share it with your colleagues.
Using our network monitoring tools, you will be able to reproduce arbitrary fragments of previously recorded data on the screen and export it in raw binary or text format.
Basic network packets tracer capabilities include viewing and navigating through the monitored data. All visualizers allow a given data pattern to be easily found using the powerful search feature. Quick search may be performed either throughout the whole visualizer window or among the selected area only.
Some visualizers also provide advanced searching capabilities, including searching for text in different encodings or binary data and a search with regular expressions.
Our product allows you to decode network packets and extract the most detailed information with flexible output customization capabilities. You can explore and view binary or text data for each monitored packet in all character encodings supported by Windows platform.
You can group entire data, assign your own structures and color schemes, specify rules to highlight certain data sequences with support for regular expressions and much more.
Our traffic analysis tools offer you graphical and statistical analysis of data obtained during the sniffing of TCP/IP & UDP connections. You can analyze not only real-time data, but also historical data stored in pre-recorded log files.
You can inspect the following data parameters: Packets Total/sec, Bytes Total/sec, Bytes Read/sec, Bytes Written/sec, IO Packets/sec. The product allows you to customize the list of data being analyzed, and specify the type and form of the analysis.
Structure View network packet explorer is a two-part window. First part displays internal structure of packet parsed according to specified set of network protocols. Second part displays raw packet contents. Cursor navigation may be synchronized between two parts. Each packet is matched against one or more of loaded protocol definition files and all protocol fields are shown in the top part of the visualizer. For each field, its name, value, starting address and size are displayed. If field consists of other fields, you may expand it.
This netanalyzer supports configuring protocol-based filtering (aka Display Filter) and allows changing of the root protocol.
The visualizer has two windows, one of which displays data read from network, and another one displays data transmitted to network.
All subsequent network packets are concatenated into a single data stream, which is displayed as sequence of hexadecimal, decimal, octal, binary data and text. Alternatively, the network dataflow may be displayed as a sequence of floating-point numbers with single or double precision.
The data visualizer is extremely flexible and allows you to customize output layout and appearance.
This exporter parses captured network data according to the loaded set of network protocols, applies optional protocol-based filtering and Root Protocol and writes the resulting binary data into the output file. It produces the result identical to the lower part of the Structure View data visualizer, but does not display any UI, writing raw data directly to the file.
This exporter parses captured network data according to the loaded set of network protocols, applies optional protocol-based filtering and Root Protocol and writes the resulting text data into the output file. It formats its textual output exactly like the upper part of the Structure View data visualizer, but does not display any UI, writing formatted data directly to the file.
HTTP View data visualizer, which is based on "Custom View" network data tracer, decodes and displays HTTP requests and responses.
The built-in script debugger simplifies the process of script authoring. During debugging, expression evaluation, variable watching and stack tracing are provided. A script execution may be traced or continued until the next breakpoint is hit.
A filter is a single condition which follows the syntax of Protocol Definition expressions. It can refer to any field in captured network packet and supports logical or arithmetic operators. Our software network analyzer is supplied with a list of predefined filters, you may also create and use your own custom filter.
This feature supports joining monitored data from multiple network adapters into a single monitoring session. Network protocol analyser parses packets coming from different sources, arranges them in the correct sequence and displays them using supported data visualizers. Network data logging feature also supports multi-source monitoring sessions.
Custom Visualizer allows the user to create his own visualizer in TypeScript. Custom network data visualizer receives each packet parsed according to selected protocol and adds one or more text strings to the output. It also defines several visual schemes which may be customized by the user for convenient output.
Our network protocol analyser comes with a lot of pre-installed protocols.
This feature allows you to add new definition of the custom protocol to the product. Then network snooper will be able to start parsing and decoding all matching packets according to this custom protocol definition.
You may use "Custom network data visualizers" feature, "MODBUS Send" and scripting to build automatic Modbus events handling solution. Use TCP MODBUS RTU/ACSII sniffer to parse function codes from requests and responses, build your TCP MODBUS packets, then automatically send them to the device using MODBUD Send and Scripting upon receiving specific data.
MODBUS Send window provides you with an easy way to control MODBUS-compatible devices. This feature can help in the process of debugging your MODBUS-compatible device, for example, you can test it by sending commands and verifying responses. You can set all standard or user-defined MODBUS function codes and then click on the Send button. It is convenient to use MODBUS parser in a conjunction with MODBUS Send for two-way debugging (view both requests & responses).
Packet builder/sender allows you to create network packets and templates according to the pre-configured or user-defined protocol definition and send them to the network adapter. This function may be used to construct and send TCP packets, IP packets, UDP packets, ARP, DHCP, ICMP, LLMNR, NetBIOS/NBNS, NetBIOS/NBSS, DNS packets and MODBUS TCP packets. There are several settings available in order to help user to automate packet sending process.
