It was - * automatically generated from specially formatted comment blocks in - * OpenVPN's source code using Doxygen. (See - * http://www.stack.nl/~dimitri/doxygen/ for more information on Doxygen) - * - * The \ref mainpage_modules "Modules section" below gives an introduction - * into the high-level module concepts used throughout this documentation. - * The \ref mainpage_relatedpages "Related Pages section" below describes - * various special subjects related to OpenVPN's implementation which are - * discussed in the related pages section. - * - * @section mainpage_modules Modules - * - * For the purpose of describing the internal structure of OpenVPN, this - * documentation and the underlying source code has been broken up into a - * number of conceptually well-defined parts, known as modules. Each - * module plays a specific role within the OpenVPN process, and in most - * cases each module has a clear interfacing strategy for interacting with - * other modules. - * - * The following modules have been defined: - * - Driver module: - * - The \link eventloop Main Event Loop\endlink: this module drives the - * event handling of OpenVPN. It implements various types of - * select-loop which wait until an event happens, and then delegate - * the handling of that event to the appropriate module. - * - Network interface modules: - * - The \link external_multiplexer External Multiplexer\endlink: this - * module sends and receives packets to and from remote OpenVPN peers - * over the external network interface. It also takes care of - * demultiplexing received packets to their appropriate VPN tunnel and - * splitting control channel and data channel packets. - * - The \link internal_multiplexer Internal Multiplexer\endlink: this - * module sends and receives packets to and from locally reachable - * posts over the virtual tun/tap network interface. It also takes - * care of determining through which VPN tunnel a received packet must - * be sent to reach its destination. - * - Control channel modules: - * - The \link reliable Reliability Layer\endlink: this module offers a - * %reliable and sequential transport layer for control channel - * messages. - * - The \link control_tls Control Channel TLS module\endlink: this - * module offers a secure encapsulation of control channel messages - * using the TLS protocol. - * - The \link control_processor Control Channel Processor\endlink: his - * module manages the setup, maintenance, and shut down of VPN - * tunnels. - * - Data channel modules: - * - The \link data_control Data Channel Control module\endlink: this - * module controls the processing of data channel packets and, - * depending on the settings of the packet's VPN tunnel, passes the - * packet to the three modules below for handling. - * - The \link data_crypto Data Channel Crypto module\endlink: this - * module performs security operations on data channel packets. - * - The \link fragmentation Data Channel Fragmentation module\endlink: - * this module offers fragmentation of data channel packets larger - * than the VPN tunnel's MTU. - * - The \link compression Data Channel Compression module\endlink: this - * module offers compression of data channel packets. - * - * @subsection mainpage_modules_example Example event: receiving a packet - * - * OpenVPN handles many types of events during operation. These include - * external events, such as network traffic being received, and internal - * events, such as a %key session timing out causing renegotiation. An - * example event, receiving a packet over the network, is described here - * together with which modules play what roles: - * -# The \link eventloop Main Event Loop\endlink detects that a packet - * can be read from the external or the virtual tun/tap network - * interface. - * -# The \link eventloop Main Event Loop\endlink calls the \link - * external_multiplexer External Multiplexer\endlink or \link - * internal_multiplexer Internal Multiplexer\endlink to read and - * process the packet. - * -# The multiplexer module determines the type of packet and its - * destination, and passes the packet on to the appropriate handling - * module: - * - A control channel packet received by the \link - * external_multiplexer External Multiplexer\endlink is passed on - * through the \link reliable Reliability Layer\endlink and the \link - * control_tls Control Channel TLS module\endlink to the \link - * control_processor Control Channel Processor\endlink. - * - A data channel packet received by either multiplexer module is - * passed on to the \link data_control Data Channel Control - * module\endlink. - * -# The packet is processed by the appropriate control channel or data - * channel modules. - * -# If, after processing the packet, a resulting packet is generated - * that needs to be sent to a local or remote destination, it is given - * to the \link external_multiplexer External Multiplexer\endlink or - * \link internal_multiplexer Internal Multiplexer\endlink for sending. - * -# If a packet is waiting to be sent by either multiplexer module and - * the \link eventloop Main Event Loop\endlink detects that data can be - * written to the associated network interface, it calls the - * multiplexer module to send the packet. - * - * @section mainpage_relatedpages Related pages - * - * This documentation includes a number of descriptions of various aspects - * of OpenVPN and its implementation. These are not directly related to - * one module, function, or data structure, and are therefore listed - * separately under "Related Pages". - * - * @subsection mainpage_relatedpages_key_generation Data channel key generation - * - * The @ref key_generation "Data channel key generation" related page - * describes how, during VPN tunnel setup and renegotiation, OpenVPN peers - * generate and exchange the %key material required for the symmetric - * encryption/decryption and HMAC signing/verifying security operations - * performed on data channel packets. - * - * @subsection mainpage_relatedpages_tunnel_state VPN tunnel state - * - * The @ref tunnel_state "Structure of VPN tunnel state storage" related - * page describes how an OpenVPN process manages the state information - * associated with its active VPN tunnels. - * - * @subsection mainpage_relatedpages_network_protocol Network protocol - * - * The @ref network_protocol "Network protocol" related page describes the - * format and content of VPN tunnel packets exchanged between OpenVPN - * peers. - * - * @subsection mainpage_relatedpages_memory_management Memory management - * - * The @ref memory_management "Memory management strategies" related page - * gives a brief introduction into OpenVPN's memory %buffer library and - * garbage collection facilities. - */ -- cgit v1.2.3
