+ *
+ *
SCTP channels support non-blocking connection: A
+ * channel may be created and the process of establishing the link to
+ * the remote socket may be initiated via the {@link #connect connect} method
+ * for later completion by the {@link #finishConnect finishConnect} method.
+ * Whether or not a connection operation is in progress may be determined by

+/**
+ * A selectable channel for message-oriented SCTP sockets.
+ *
+ *
An SCTP multi channel supports many associations on a single socket.
+ * An {@code SctpMultiChannel} is created by invoking the
+ * {@link #open open} method of this class. A newly-created channel is open but
+ * not yet bound. An attempt to invoke the {@link #receive receive} method of an
+ * unbound channel will cause the {@link NotYetBoundException}
+ * to be thrown. An attempt to invoke the {@link #send send} method of an
+ * unbound channel will cause it to first invoke the {@link #bind bind} method.
+ * The address(es) that the channel's socket is bound to can be retrieved by
+ * calling {@link #getAllLocalAddresses getAllLocalAddresses}.
+ *
+ *
Messages may be sent and received without explicitly setting up an
+ * association with the remote peer. The channel will implicitly setup
+ * a new association whenever it sends or receives a message from a remote
+ * peer if there is not already an association with that peer. Upon successful
+ * association setup, an {@link AssociationChangeNotification
+ * association changed} notification will be put to the SCTP stack with its
+ * {@code event} parameter set to {@link
+ * AssociationChangeNotification.AssocChangeEvent#COMM_UP
+ * COMM_UP}. This notification can be received by invoking {@link #receive
+ * receive}.
+ *
+ *
Socket options are configured using the
+ * {@link #setOption(SctpSocketOption,Object,Association) setOption} method. An
+ * {@code SctpMultiChannel} supports the following options:
+ *
+ *
+ *
+ * Option Name
+ * Description
+ *
+ *
+ * {@link SctpStandardSocketOption#SCTP_DISABLE_FRAGMENTS
+ * SCTP_DISABLE_FRAGMENTS}
+ * Enables or disables message fragmentation
+ *
+ *
+ * {@link SctpStandardSocketOption#SCTP_EXPLICIT_COMPLETE
+ * SCTP_EXPLICIT_COMPLETE}
+ * Enables or disables explicit message completion
+ *
+ *
+ * {@link SctpStandardSocketOption#SCTP_FRAGMENT_INTERLEAVE
+ * SCTP_FRAGMENT_INTERLEAVE}
+ * Controls how the presentation of messages occur for the message
+ * receiver
+ *
+ *
+ * {@link SctpStandardSocketOption#SCTP_INIT_MAXSTREAMS
+ * SCTP_INIT_MAXSTREAMS}
+ * The maximum number of streams requested by the local endpoint during
+ * association initialization
+ *
+ *
+ * {@link SctpStandardSocketOption#SCTP_NODELAY SCTP_NODELAY}
+ * Enables or disable a Nagle-like algorithm
+ *
+ *
+ * {@link SctpStandardSocketOption#SCTP_PRIMARY_ADDR
+ * SCTP_PRIMARY_ADDR}
+ * Requests that the local SCTP stack use the given peer address as the
+ * association primary
+ *
+ *
+ * {@link SctpStandardSocketOption#SCTP_SET_PEER_PRIMARY_ADDR
+ * SCTP_SET_PEER_PRIMARY_ADDR}
+ * Requests that the peer mark the enclosed address as the association
+ * primary
+ *
+ *
+ * {@link SctpStandardSocketOption#SO_SNDBUF
+ * SO_SNDBUF}
+ * The size of the socket send buffer
+ *
+ *
+ * {@link SctpStandardSocketOption#SO_RCVBUF
+ * SO_RCVBUF}
+ * The size of the socket receive buffer
+ *
+ *
+ * {@link SctpStandardSocketOption#SO_LINGER
+ * SO_LINGER}
+ * Linger on close if data is present (when configured in blocking mode
+ * only)
+ *
+ *
+ *
+ * Additional (implementation specific) options may also be supported. The list
+ * of options supported is obtained by invoking the {@link #supportedOptions()
+ * supportedOptions} method.
+ *

+ *
+ * This option takes an {@code Integer} value. It can be set to a value

+ *
+ *
Setting the three levels provides the following receiver
+ * interactions:
+ *
+ *
{@code level 0} - Prevents the interleaving of any messages. This
+ * means that when a partial delivery begins, no other messages will be
+ * received except the message being partially delivered. If another message
+ * arrives on a different stream (or association) that could be delivered,
+ * it will be blocked waiting for the user to read all of the partially
+ * delivered message.
+ *
+ *
{@code level 1} - Allows interleaving of messages that are from
+ * different associations. For {@code SctpChannel}, level 0 and
+ * level 1 have the same meaning since an {@code SctpChannel} always
+ * receives messages from the same association. Note that setting an {@code
+ * SctpMultiChannel} to this level may cause multiple partial
+ * delivers from different associations but for any given association, only
+ * one message will be delivered until all parts of a message have been
+ * delivered. This means that one large message, being read with an
+ * association identification of "X", will block other messages from
+ * association "X" from being delivered.
+ *
+ *
{@code level 2} - Allows complete interleaving of messages. This
+ * level requires that the sender carefully observe not only the peer
+ * {@code Association} but also must pay careful attention to the stream
+ * number. With this option enabled a partially delivered message may begin
+ * being delivered for association "X" stream "Y" and the next subsequent
+ * receive may return a message from association "X" stream "Z". Note that
+ * no other messages would be delivered for association "X" stream "Y"
+ * until all of stream "Y"'s partially delivered message was read.
+ * Note that this option effects both channel types. Also note that
+ * for an {@code SctpMultiChannel} not only may another streams
+ * message from the same association be delivered from the next receive,
+ * some other associations message may be delivered upon the next receive.

+/**
+ * A Java API for Stream Control Transport Protocol.
+ *
+ *
The Stream Control Transport Protocol (SCTP) is a reliable,
+ * message-oriented, transport protocol existing at an equivalent level with UDP
+ * (User Datagram Protocol) and TCP (Transmission Control Protocol). SCTP is
+ * session oriented and an association between the endpoints must be established
+ * before any data can be transmitted.
+ *
+ *
SCTP has direct support for multi-homing, meaning than an endpoint may be
+ * represented by more than one address and each address may be used for sending
+ * and receiving data, thus providing network redundancy. The connection between
+ * two endpoints is referred to as an association between those endpoints.
+ * Endpoints can exchange a list of addresses during association setup. One
+ * address is designated as the primary address, this is the default address that
+ * the peer will use for sending data. A single port number is used across the
+ * entire address list at an endpoint for a specific session.
+ *
+ *
SCTP is message based. I/O operations operate upon messages and message
+ * boundaries are preserved. Each association may support multiple independant
+ * logical streams. Each stream represents a sequence of messages within a single
+ * association and streams are independant of one another, meaning that stream
+ * identifiers and sequence numbers are included in the data packet to allow
+ * sequencing of messages on a per-stream basis.
+ *
+ *
This package provides two programming model styles. The one-to-one style
+ * supported by {@link com.sun.nio.sctp.SctpChannel} and {@link
+ * com.sun.nio.sctp.SctpServerChannel}, and the one-to-many
+ * style supported by {@link com.sun.nio.sctp.SctpMultiChannel}.
+ * The semantics of the one-to-one style interface are very similar to TCP.
+ * An {@code SctpChannel} can only control one SCTP association. The
+ * semantics of the one-to-many style interface are very similar to UDP. An
+ * {@code SctpMutliChannel} can control multiple SCTP associations.
+ *
+ *
Applications can send and receive per-message ancillary information through
+ * {@link com.sun.nio.sctp.MessageInfo}. For example, the stream number that
+ * the message it is to be sent or received from. The SCTP stack is event driven
+ * and applications can receive notifications of certain SCTP events by invoking
+ * the {@code receive} method of the SCTP channel with an appropriate {@link
+ * com.sun.nio.sctp.NotificationHandler notification handler}.
+ *
+ *
The SCTP protocol is defined by
+ * RFC4960 , and the optional
+ * extension for Dynamic Address Reconfiguration is defined by
+ * RFC5061 .
+ *
+ * @since 1.7
