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: + *

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 + */ + +package com.sun.nio.sctp; diff --git a/src/share/classes/sun/nio/ch/SctpMessageInfoImpl.java b/src/share/classes/sun/nio/ch/SctpMessageInfoImpl.java new file mode 100644 index 000000000..cc5a06467 --- /dev/null +++ b/src/share/classes/sun/nio/ch/SctpMessageInfoImpl.java @@ -0,0 +1,170 @@ +/* + * Copyright 2009 Sun Microsystems, Inc.
