//
// PROTOCOL DESCRIPTION
//
// Connection Process
// ------------------
//
// Clients connect to the voice session by sending a DVPROTOCOLMSG_CONNECTREQUEST.
// The host then determines if the client is allowed to join the session. If
// the client's request is rejected, the client receives a DVPROTOCOLMSG_CONNECTREFUSE.
// If the client's request is accepted, the client receives a
// DVPROTOCOLMSG_CONNECTACCEPT. This packet contains all the information the client
// requires to determine if they are compatible.
//
// The client will then attempt to initialize themselves using the compression
// type transmitted by the server. If the client fails to initialize it takes
// no further action. If the client initializes succesfully it transmits a
// DVPROTOCOLMSG_SETTINGSCONFIRM message and is added to the session. All players
// in the session will then receive a DVPROTOCOLMSG_PLAYERJOIN.
//
// Until a DVPROTOCOLMSG_SETTINGSCONFIRM message is received by the host, the client is
// not considered to be part of the session. As such it will not transmit
// speech. (However, it may receive speech).
//
// The server then sends DVPROTOCOLMSG_PLAYERLIST message(s) to give the client the
// current player table. (Peer to peer only).
//
// Disconnection Process
// ---------------------
//
// If a client wishes to disconnect from the voice session, it sends a
// DVPROTOCOLMSG_DISCONNECT message to the host. The host will then transmit
// to all players a DVPROTOCOLMSG_PLAYERQUIT message and will send a
// DVPROTOCOLMSG_DISCONNECT message back to the player to confirm.
//
// If the client disconnects unexpectedly the voice host will detect this and
// will automatically send DVPROTOCOLMSG_PLAYERQUIT messages to all the other clients
// in the session.
//
// Speech Messages
// ---------------
//
// Speech messages are described in detail in the description for DVPROTOCOLMSG_SPEECH.
//
// Messages sent from the host are sent with the DVMSGID_SPEECHBOUNCE instead
// of DVMSGID_SPEECH so that whena host and client share a single dplay id
// the client can ignore it's own speech packets.
//
// Host Migration
// --------------
//
// NEW HOST MIGRATION
//
// Pros/Cons:
//
// First, the advantages to the new system:
// - The new host migration mechanism allows DirectPlay Voice to have a host
// - seperate from the directplay host.
// - Shutting down the host without stopping the dplay interface causes voice host
// to migrate.
// - Minimizes changes to directplay.
// - Removes requirement that all clients had to run voice clients.
// - You can prevent the host from migrating when you call stopsession by
// specifying the new DVFLAGS_NOHOSTMIGRATE which causes the session to be
// stopped.
//
// Disadvantages of the new system:
// - If there are no voice clients in the session when the host is lost, then the
// voice session will be lost.
//
// Host Election
//
// In order to elect a new host, each client is given a "Host Order ID" when
// they have completed their connection. All clients are informed of an
// individual's "Host Order ID" when they find out about the player. These
// identifiers start at 0, are a DWORD in size, and are incremented with each
// new user. Therefore the first player in the session will have ID 0, the
// second will have ID 1, etc.
//
// By using this method we ensure that the client elected to be the host will be
// the oldest client in the session. This has the advantage (because of the way
// the name table is distributed) if any client has any clients at all, they
// will have the oldest clients. Therefore everyone in the session will either
// have just themselves, or at the very least the client who will become the new
// host. If a client doesn't have anyone in the session, it means they either
// are the only ones in the session (in which case they become the new host) or
// they haven't received the name table yet. If they haven't received the name
// table they will not yet have a "Host Order ID" and will therefore be
// inelligable to become the new host.
//
// When the host migrates to a new host, the new host offsets a constant (in
// this case defined in dvcleng.cpp as DVMIGRATE_ORDERID_OFFSET) from it's own
// Host Order ID and uses it as the next Host Order ID to hand out. (So
// duplicate host order IDs are not handed out).
//
// Unless.. you get DVMIGRATE_ORDERID_OFFSET connects between when the new host
// joined and a new player joins before a player with a higher ID joins. (If a
// player informs the server that it's Host Order ID is > then the seed the host
// bumps the seed to be DVMIGRATE_ORDERID_OFFSET from the user's value). In
// this case you may end up with > 1 host. (But this case is extremely unlikely).
//
// How It's Implemented
//
// Each client in the session knows the DPID of the host. Therefore, to detect
// the situation where the host will migrate the client looks at if the session
// supports host migration and for one of two things:
//
// - A DVPROTOCOLMSG_HOSTMIGRATELEAVE message - This is sent by the host when StopSession (
// without the DVFLAGS_NOHOSTMIGRATE flag) or Release is called.
// - DirectPlay informs DirectPlay Voice that the player ID belonging to the
// session host has left the session.
//
// Once one of the above occurs, each clients runs the new host election
// algorithm. Their action will depend on the situation:
//
// - If no clients are found that are elligible to become the new host. Then the
// client will disconnect.
// - If clients are found that are elligible to become the new host but it is not
// the local client, the local client takes no action.
// - If the local client is to be the new host then it starts up a new host locally.
//
// Once the new host starts up, it will send a DVPROTOCOLMSG_HOSTMIGRATE message to all
// the users in the session. Each client in the session responds with their
// current settings using a DVPROTOCOLMSG_SETTINGSCONFIRM message (which includes the
// client's current "Host Order ID". Using these messages the new host rebuilds
// the player list. Also, in response to the DVPROTOCOLMSG_SETTINGSCONFIRM message each
// client receives a copy of the latest name table. For players who respond to
// the host migration after you, DVPROTOCOLMSG_CREATEVOICEPLAYER messages will be sent.
// This player ensures that every client ends up with a proper and up to date
// name table.
//
// Each client in the session ignores duplicate CREATEVOICEPLAYER messages.
//
// The client object that creates the new host holds a reference to the new host
// and will destroy it when the client is destroyed. (Possibly causing the host
// to migrate again).
//
// Session Losses
//
// Using this new scheme it is possible to lose the voice session if there are
// no voice clients elligeble to become the new voice host. (Meaning there are
// no clients properly connected). All clients which are not yet completed
// their connection will detect this situation and will disconnect from the
// session.
//
// In addition, when the host goes to stop, it checks to see if there are any
// clients elligeble to become the host. If there are none it transmits a
// DVPROTOCOLMSG_SESSIONLOST message to all players in the session.
//
// Notes:
//
// One thing to watch for is since the DirectPlayVoice host may migrate to a
// different client then the DirectPlay host does, just because you know who the
// DirectPlay Host is doesn't mean you know who the voice host is.
//
// In order to implement this new mechanism the following related changes were
// made:
//
// - Clients with differing major/minor/build protocol version numbers are
// rejected by the host now. The result is that new clients may be able to
// connect to old hosts but may crash, and old clients are now rejected by new
// hosts. (Handling of these cases on old clients was not good -- just don't do
// it).
// - DirectPlay host migration messages are ignored.
// - Connection requests are sent to everyone in the session. The client
// determines who the host is by seeing who responded to their message.
// - Handling of rejection messages now results in the connection failing. (There
// was a bug).
// - The rejection message now contains the major/minor/build protocol version of
// the host.
// - Instead of sending individual messages for each user in the current session
// to a client when it first joins the host now sends a DVPROTOCOLMSG_PLAYERLIST which
// is a list of players in the session. This reduces bandwidth and makes the
// connection process shorter.
