+/**
+ * A selectable channel for message-oriented SCTP sockets.
+ *
+ * <P> 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}.
+ *
+ * <P> 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}.
+ *
+ * <P> Socket options are configured using the
+ * {@link #setOption(SctpSocketOption,Object,Association) setOption} method. An

+     * 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,

+     * delivered message.

+     * <P> {@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

+     * 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.
+     *
+     * <P> {@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.
+ *
+ * <P> 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.
+ *
+ * <P> 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.
+ *
+ * <P> 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.
+ *
+ * <P> 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.
+ *
+ * <P> 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}.
+ *
+ * <P> The SCTP protocol is defined by
+ * <A HREF="http://tools.ietf.org/html/rfc4960">RFC4960</A>, and the optional
+ * extension for <I>Dynamic Address Reconfiguration</I> is defined by
+ * <A HREF="http://tools.ietf.org/html/rfc5061">RFC5061</A>.
+ *
+ * @since 1.7
