UDP lacks sequencing, connection +management, management of bandwidth resources, and imposes limitations on +the size of packets. A significant investment is required to integrate these +two protocols, and the end result is worse off in features and performance +than the uniform protocol presented by ENet. + + ENet thus attempts to address these issues and provide a single, uniform +protocol layered over UDP to the developer with the best features of UDP and +TCP as well as some useful features neither provide, with a much cleaner +integration than any resulting from a mixture of UDP and TCP. + +* Connection management + + ENet provides a simple connection interface over which to communicate +with a foreign host. The liveness of the connection is actively monitored +by pinging the foreign host at frequent intervals, and also monitors the +network conditions from the local host to the foreign host such as the +mean round trip time and packet loss in this fashion. + +* Sequencing + + Rather than a single byte stream that complicates the delineation +of packets, ENet presents connections as multiple, properly sequenced packet +streams that simplify the transfer of various types of data. + + ENet provides sequencing for all packets by assigning to each sent +packet a sequence number that is incremented as packets are sent. ENet +guarentees that no packet with a higher sequence number will be delivered +before a packet with a lower sequence number, thus ensuring packets are +delivered exactly in the order they are sent. + + For unreliable packets, ENet will simply discard the lower sequence +number packet if a packet with a higher sequence number has already been +delivered.

ENet will attempt +to resend the packet up to a reasonable amount of times, if no acknowledgement +of the packet's receipt happens within a specified timeout. Retry timeouts +are progressive and become more lenient with every failed attempt to allow +for temporary turbulence in network conditions. + +* Fragmentation and reassembly + + ENet will send and deliver packets regardless of size. Large packets are +fragmented into many smaller packets of suitable size, and reassembled on +the foreign host to recover the original packet for delivery. The process +is entirely transparent to the developer. + +* Aggregation + + ENet aggregates all protocol commands, including acknowledgements and +packet transfer, into larger protocol packets to ensure the proper utilization +of the connection and to limit the opportunities for packet loss that might +otherwise result in further delivery latency. + +* Adaptability + + ENet provides an in-flight data window for reliable packets to ensure +connections are not overwhelmed by volumes of packets.

ENet hosts are polled for events with enet_host_service(), +where an optional timeout value in milliseconds may be specified to +control how long ENet will poll; if a timeout of 0 is specified, +enet_host_service() will return immediately if there are no events to +dispatch. enet_host_service() will return 1 if an event was dispatched +within the specified timeout. + +Currently there are only four types of significant events in ENet: + +An event of type ENET_EVENT_TYPE_NONE is returned if no event occurred +within the specified time limit. enet_host_service() will return 0 +with this event. + +An event of type ENET_EVENT_TYPE_CONNECT is returned when either a new client +host has connected to the server host or when an attempt to establish a +connection with a foreign host has succeeded.

The "peer" field contains the peer the packet was +received from, "channelID" is the channel on which the packet was sent, and +"packet" is the packet that was sent. The packet contained in the "packet" +field must be destroyed with enet_packet_destroy() when you are done +inspecting its contents. + +An event of type ENET_EVENT_TYPE_DISCONNECT is returned when a connected peer +has either explicitly disconnected or timed out. Only the "peer" field of the +event structure is valid for this event and contains the peer that +disconnected. Only the "data" field of the peer is still valid on a +disconnect event and must be explicitly reset. + +@code + ENetEvent event; + + /* Wait up to 1000 milliseconds for an event. */ + while (enet_host_service (client, & event, 1000) > 0) + { + switch (event.type) + { + case ENET_EVENT_TYPE_CONNECT: + printf ("A new client connected from %x:%u.\n", + event.peer -> address.host, + event.peer -> address.port); + + /* Store any relevant client information here. */ + event.peer -> data = "Client information"; + + break; + + case ENET_EVENT_TYPE_RECEIVE: + printf ("A packet of length %u containing %s was received from %s on channel %u.\n", + event.packet -> dataLength, + event.packet -> data, + event.peer -> data, + event.channelID); + + /* Clean up the packet now that we're done using it. */ + enet_packet_destroy (event.packet); + + break; + + case ENET_EVENT_TYPE_DISCONNECT: + printf ("%s disconected.\n", event.peer -> data); + + /* Reset the peer's client information. */ + + event.peer -> data = NULL; + } + } + ... + ... + ... +@endcode + +@section SendingPacket Sending a packet to an ENet peer + +Packets in ENet are created with enet_packet_create(), where the size +of the packet must be specified. Optionally, initial data may be +specified to copy into the packet. + +Certain flags may also be supplied to enet_packet_create() to control +various packet features: + +ENET_PACKET_FLAG_RELIABLE specifies that the packet must use reliable +delivery. A reliable packet is guarenteed to be delivered, and a +number of retry attempts will be made until an acknowledgement is +received from the foreign host the packet is sent to. If a certain +number of retry attempts is reached without any acknowledgement, ENet +will assume the peer has disconnected and forcefully reset the +connection. If this flag is not specified, the packet is assumed an +unreliable packet, and no retry attempts will be made nor +acknowledgements generated. + +A packet may be resized (extended or truncated) with +enet_packet_resize(). + +A packet is sent to a foreign host with +enet_peer_send(). enet_peer_send() accepts a channel id over which to +send the packet to a given peer. Once the packet is handed over to +ENet with enet_peer_send(), ENet will handle its deallocation and +enet_packet_destroy() should not be used upon it. + +One may also use enet_host_broadcast() to send a packet to all +connected peers on a given host over a specified channel id, as with +enet_peer_send(). + +Queued packets will be sent on a call to enet_host_service(). +Alternatively, enet_host_flush() will send out queued packets without +dispatching any events. + +@code + /* Create a reliable packet of size 7 containing "packet\0" */ + ENetPacket * packet = enet_packet_create ("packet", + strlen ("packet") + 1, + ENET_PACKET_FLAG_RELIABLE); + + /* Extend the packet so and append the string "foo", so it now */ + /* contains "packetfoo\0" */ + enet_packet_resize (packet, strlen ("packetfoo") + 1); + strcpy (& packet -> data [strlen ("packet")], "foo"); + + /* Send the packet to the peer over channel id 0. */ + /* One could also broadcast the packet by */ + /* enet_host_broadcast (host, 0, packet); */ + enet_peer_send (peer, 0, packet); + ... + ... + ... + /* One could just use enet_host_service() instead. */ + enet_host_flush (host); +@endcode + +@section Disconnecting Disconnecting an ENet peer + +Peers may be gently disconnected with enet_peer_disconnect(). A +disconnect request will be sent to the foreign host, and ENet will +wait for an acknowledgement from the foreign host before finally +disconnecting. An event of type ENET_EVENT_TYPE_DISCONNECT will be +generated once the disconnection succeeds. Normally timeouts apply to +the disconnect acknowledgement, and so if no acknowledgement is +received after a length of time the peer will be forcefully +disconnected. + +enet_peer_reset() will forcefully disconnect a peer. The foreign host +will get no notification of a disconnect and will time out on the +foreign host. No event is generated. + +@code + ENetEvent event; + + enet_peer_disconnect (peer, 0); + + /* Allow up to 3 seconds for the disconnect to succeed + * and drop any packets received packets. + */ + while (enet_host_service (client, & event, 3000) > 0) + { + switch (event.type) + { + case ENET_EVENT_TYPE_RECEIVE: + enet_packet_destroy (event.packet); + break; + + case ENET_EVENT_TYPE_DISCONNECT: + puts ("Disconnection succeeded."); + return; + ... + ... + ... + } + } + + /* We've arrived here, so the disconnect attempt didn't */ + /* succeed yet.
