- * NOTE: Do not change this documentation. This documentation is based on
- * gnunet.org:/vcs/fsnsg/2014-p2p-ats.git/tech-doku/ats-tech-guide.tex
- * use build_txt.sh to generate plaintext output
- *
- * 1 ATS addresses : ATS address management
- *
- * This ATS addresses ("addresses") component manages the addresses known to
- * ATS service and suggests addresses to transport service when it is
- * interested in address suggestion for a peer. ATS addresses also
- * instantiates the bandwidth assignment mechanism (solver), notifies it
- * about changes to addresses and forwards changes to bandwidth assignments
- * to transport, depending if transport is interested in this change.
- *
- * 1.1 Input data
- *
- * 1.1.1 Addresses
- *
- * Addresses are added by specifying peer ID, plugin, address, address length
- * and session, if available. ATS information can be specified if available.
- *
- * 1.1.2 Networks
- *
- * ATS specifies a fix set of networks an address can belong to. For each
- * network an inbound and outbound quota will be specified. The available
- * networks and addtional helper varaibles are defined in
- * gnunet_ats_service.h. At the moment 5 networks are defined:
- * * GNUNET_ATS_NET_UNSPECIFIED
- * * GNUNET_ATS_NET_LOOPBACK
- * * GNUNET_ATS_NET_LAN
- * * GNUNET_ATS_NET_WAN
- * * GNUNET_ATS_NET_WLAN
- *
- * The total number of networks defined is stored in
- * GNUNET_ATS_NetworkTypeCount GNUNET_ATS_NetworkType can be used array
- * initializer for an int array, while GNUNET_ATS_NetworkType is an
- * initializer for a char array containing a string description of all
- * networks
- *
- * 1.1.3 Quotas
- *
- * An inbound and outbound quota for each of the networks mentioned in 1.1.2
- * is loaded from ats configuration during initialization. This quota defines
- * to total amount of inbound and outbound traffic allowed for a specific
- * network. The configuration values used are in section ats:
- * * "NETWORK"_QUOTA_IN = <value>
- * * "NETWORK"_QUOTA_IN = <value>
- *
- * You can specify quotas by setting the <value> to a:
- * * unrestricted: unlimited
- * * number of bytes: e.g. 10240
- * * fancy value: e.g. 64 Kib
- *
- * unlimited is defined as GNUNET_ATS_MaxBandwidthString and equivalent to
- * the value GNUNET_ATS_MaxBandwidth Important predefined values for quotas
- * are:
- * * GNUNET_ATS_DefaultBandwidth: 65536
- * * GNUNET_ATS_MaxBandwidth: UINT32_MAX
- * * GNUNET_CONSTANTS_DEFAULT_BW_IN_OUT: 1024
- *
- * Details of loading quotas and default values will be described on
- *
- * 1.1.4 Preference values
- *
- * 1.2 Data structures used
- *
- * Addresse uses struct ATS_Address for each address. The structs are stored
- * in a linked list and provides a pointer void *solver_information for the
- * solver to store address specific information. It provides the int values
- * active which is set to GNUNET_YES if the address is select for transport
- * use and used, representing that transport service is actively using this
- * address. Address information are stored in peer, addr, addr_len, plugin.
- *
- * 1.3 Initialization
- *
- * During initialization a hashmap to store addresses is created. The quotas
- * for all networks defined for ATS are loaded from configuration. For each
- * network first the logic will check if the string
- * GNUNET_ATS_MaxBandwidthString is configured, if not it will try to convert
- * the configured value as a fancy size and if this fails it will try to use
- * it as a value_number. If no configuration value is found it will assign
- * GNUNET_ATS_DefaultBandwidth. The most important step is to load the
- * configured solver using configuration "[ats]:MODE". Current solvers are
- * MODE_PROPORTIONAL, MODE_MLP. Interaction is done using a solver API
- *
- * 1.4 Solver API
- *
- * Solver functions:
- * * s_init: init the solver with required information
- * * s_add: add a new address
- * * s_update: update ATS values or session for an address
- * * s_get: get prefered address for a peer
- * * s_del: delete an address
- * * s_pref: change preference value for a peer
- * * s_done: shutdown solver
- *
- * Callbacks: addresses provides a bandwidth_changed_cb callback to the
- * solver which is called when bandwidth assigned to peer has changed
- *
- * 1.5 Shutdown
- *
- * During shutdown all addresses are freed and the solver told to shutdown
- *
- * 1.6 Addresses and sessions
- *
- * Addresses consist of the address itself and a numerical session. When a
- * new address without a session is added it has no session, so it gets
- * session 0 assigned. When an address with a session is added and an address
- * object with session 0 is found, this object is updated with the session
- * otherwise a new address object with this session assigned is created.
- *
- * 1.6.1 Terminology
- *
- * Addresses a1,a2 with session s1, s2 are "exact" if:
- * (a1 == a2)&&(s1 == s2)
- * Addresses a1,a2 with session s1, s2 are "equivalent" if:
- * (a1 == a2)&&((s1 == s2)||(s1 == 0)||(s2 == 0)
- *
- * 1.7 Address management
- *
- * Transport service notifies ATS about changes to the addresses known to
- * him.
- *
- * 1.7.1 Adding an address
- *
- * When transport learns a new address it tells ATS and ATS is telling
- * addresses about it using GAS_address_add. If not known to addresses it
- * creates a new address object and calls solver's s_add. ATS information are
- * deserialized and solver is notified about the session and ATS information
- * using s_update.
- *
- * 1.7.2 Updating an address
- *
- * Addresses does an lookup up for the existing address with the given
- * session. If disassembles included ATS information and notifies the solver
- * using s_update about the update.
- *
- * 1.7.3 Deleting an address
- *
- * Addresses does an lookup for the exact address and session and if removes
- * this address. If session != 0 the session is set to 0 and the address is
- * kept. If session == 0, the addresses is removed.
- *
- * 1.7.4 Requesting an address suggestion
- *
- * The address client issues a request address message to be notified about
- * address suggestions for a specific peer. Addresses asks the solver with
- * s_get. If no address is available, it will not send a response, otherwise
- * it will respond with the choosen address.
- *
- * 1.7.5 Address suggestions
- *
- * Addresses will notify the client automatically on any bandwidth_changed_cb
- * by the solver if a address suggestion request is pending. If no address is
- * available it will not respond at all If the client is not interested
- * anymore, it has to cancel the address suggestion request.
- *
- * 1.7.6 Address lifecycle
- *
- * * (add address)
- * * (updated address)
- * * (delete address)
- *
- * 1.8 Bandwidth assignment
- *
- * The addresses are used to perform resource allocation operations. ATS
- * addresses takes care of instantiating the solver configured and notifies
- * the respective solver about address changes and receives changes to the
- * bandwidth assignment from the solver. The current bandwidth assignment is
- * sent to transport. The specific solvers will be described in the specific
- * section.
- *
- * 1.9 Changing peer preferences
- *
- * The bandwidth assigned to a peer can be influenced by setting a preference
- * for a peer. The prefernce will be given to to the solver with s_pref which
- * has to take care of the preference value
