/**
|
|
* 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
