![]() Using custom visualizers, deep protocol analysis features and scripting you'll be even able to handle certain events. This is entirely a software network sniffing, analyzing and data logging solution that requires no additional hardware equipment. Our network data capturing software has been developed and constantly improved for more than 15 years. It has an intuitive user interface, detailed documentation with examples and requires no special programming skills to start using it. Download this network analyzer now and start to trace network packets in a few seconds!Ĭapturing 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.įor 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.Īll 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.In intranet or internet networks, it is very common for unauthorized access to critical or production servers.
