Core Protocol Pack

Core Protocol pack consisting of many common protocols and runtime support for other modules.

Optional additional modules

• Web protocol pack - TLS/SSL, Quic, etc...
• (several others under development) - Coming soon!
  • Telco/Carrier protocol pack
  • Voice/Video protocol pack - with various codecs and streaming protocols
  • Database protocol pack - database monitoring and quality assurance
  • System tables - auxilary module with support for ARP, ROUTING and other system tables

How to use this module

This module, core-protocols is an extension module which provides protocol level support for one of the main public APIs. You need to setup your application using either jnetpcap-pro or jNetWorks (Coming Soon!) modules which provide the main APIs for building applications using any of the protocol packs.

What's inside

The core-protocols module provides support for the following services:

• Runtime support for all of the modules using combination of public and private APIs
  • Private APIs are exported to other modules and provide common implementation features across all modules
  • A small public API is also exported for things like capture Timestamp and TimestampUnit classes, etc...
• Raw packet dissection
  • Advanced packet descriptors store the results of the dissection process after packet capture
  • Information about the presence of each protocol header is recorded in PacketDescriptorType.TYPE2
• IP Fragmentation processing
  • IP fragment reassembly into full IP datagrams
  • IP fragment tracking regardless if reassembly is enabled
• A very efficient packet implementation using the Packet class
  • Instrumentation using MetaPacket class, similar to java beans
• Packet formatters, various packet formatters for displaying packet state and fields
  • A pretty print formatter which dumps easy to read details about a packet and its headers
  • Coverters for XML, JSON and other output types
• A set of protocols which are considered core or common on most networks
