This component supports producer and consumer endpoints for both TCP and UDP.

You can append query options to the URI in the following format, ?option=value&option=value&...

Options

Name	Default Value	Description
`keepAlive`	`true`	Setting to ensure socket is not closed due to inactivity
`tcpNoDelay`	`true`	Setting to improve TCP protocol performance
`backlog`		Camel 2.9.6/2.10.4/2.11: Allows to configure a backlog for netty consumer (server). Note the backlog is just a best effort depending on the OS. Setting this option to a value such as `200`, `500` or `1000`, tells the TCP stack how long the "accept" queue can be. If this option is not configured, then the backlog depends on OS setting.
`broadcast`	`false`	Setting to choose Mul ticast over UDP
`connectTimeout`	`10000`	Time to wait for a socket connection to be available. Value is in millis.
`reuseAddress`	`true`	Setting to facilitate socket multiplexing
`sync`	`true`	Setting to set endpoint as one-way or request-response
`synchronous`	`false`	Camel 2.10: Whether Asynchronous Routing Engine is not in use. `false` then the Asynchronous Routing Engine is used, `true` to force processing synchronous.
`ssl`	`false`	Setting to specify whether SSL encryption is applied to this endpoint
`sslClientCertHeaders`	`false`	Camel 2.12: When enabled and in SSL mode, then the Netty consumer will enrich the Camel Message with headers having information about the client certificate such as subject name, issuer name, serial number, and the valid date range.
`sendBufferSize`	`65536 bytes`	The TCP/UDP buffer sizes to be used during outbound communication. Size is bytes.
`receiveBufferSize`	`65536 bytes`	The TCP/UDP buffer sizes to be used during inbound communication. Size is bytes.
`option.XX X`	`null`	Camel 2.11/2.10.4: Allows to configure additional netty options using "option." as prefix. For example "option.child.keepAlive=false" to set the netty option "child.keepAlive=false". See the Netty documentation for possible options that can be used.
`corePoolSize`	`10`	The number of allocated threads at component startup. Defaults to 10. Note: This option is removed from Camel 2.9.2 onwards. As we rely on Nettys default settings.
`maxPoolSize`	`100`< /p>	The maximum number of threads that may be allocated to this endpoint. Defaults to 100. Note: This option is removed from Camel 2.9.2 onwards. As we rely on Nettys default settings.
`disconnect`	`false`	Whether or not to disconnect(close) from Netty Channel right after use. Can be used for both consumer and producer.
`lazyChannelCreation`	`true`	Channels can be lazily created to avoid exceptions, if the remote server is not up and running when the Camel producer is started.
`transferExchange`	`false`	Only used for TCP. You can transfer the exchange over the wire instead of just the body. The following fields are transferred: In body, Out body, fault body, In headers, Out headers, fault headers, exchange properties, exchange exception. This requires that the objects are serializable. Camel will exclude any non-serializable objects and log it at WARN level.
`disconnectOnNoReply`	`true`	If sync is enabled then this option dictates NettyConsumer if it should disconnect where there is no reply to send back.
`noReplyLogLevel`	`WARN`	If sync is enabled this option dictates NettyConsumer which logging level to use when logging a there is no reply to send back. Values are: `FATAL, ERROR, INFO, DEBUG, OFF`.
`serverExceptionCaughtLogLevel`	`WARN`	Camel 2.11.1: If the server (NettyConsumer) catches an exception then its logged using this logging level.
`serverClosedChannelExceptionCaughtLogLevel`	`DEBUG`	Camel 2.11.1: If the server (NettyConsumer) catches an `java.nio.channels.ClosedChannelException` then its logged using this logging level. This is used to avoid logging the closed channel exceptions, as clients can disconnect abruptly and then cause a flod of closed exceptions in the Netty server.
`allowDefaultCodec`	`true`	Camel 2.4: The netty component installs a default codec if both, encoder/deocder is null and textline is false. Setting allowDefaultCodec to false prevents the netty component from installing a default codec as the first element in the filter chain.
`textline`	`f alse`	Camel 2.4: Only used for TCP. If no codec is specified, you can use this flag to indicate a text line based codec; if not specified or the value is false, then Object Serialization is assumed over TCP.
`delimiter`	`LINE`	Camel 2.4: The delimiter to use for the textline codec. Possible values are `LINE` and `NULL`.
`decoderMaxLineLength`	`1024`	Camel 2.4: The max line length to use for the textline codec.
`autoAppendDelimiter`	`true`	Camel 2.4: Whether or not to auto append missing end delimiter when sending using the textline codec.
`encoding`	`null`	Camel 2.4: The encoding (a charset name) to use for the textline codec. If not provided, Camel will use the JVM default Charset.
`workerCount`	`null`	Camel 2.9: When netty works on nio m ode, it uses default workerCount parameter from Netty, which is cpu_core_threads*2. User can use this operation to override the default workerCount from Netty
`sslContextParameters`	`null`	Camel 2.9: SSL configuration using an `org.apache.camel.util.jsse.SSLContextParameters` instance. See Using the JSSE Configuration Utility.
`receiveBufferSizePredictor`	`null`	Camel 2.9: Configures the buffer size predictor. See details at Jetty documentatio n and this mail thread.
`requestTimeout`	`0`	Camel 2.11.1: Allows to use a timeout for the Netty producer when calling a remote server. By default no timeout is in use. The value is in milli seconds, so eg `30000` is 30 seconds.
`needClientAuth`	`false`	Camel 2.11: Configures whether the server needs client authentication when using SSL.
`orderedThreadPoolExecutor`	`true`	Camel 2.10.2: Whether to use ordered thread pool, to ensure events are processed orderly on the same channel. See details at the netty javadoc of `org.jboss.netty.handler.execution.OrderedMemoryAwareThreadPoolExecutor` for more details.
`maximumPoolSize`	`16`	Camel 2.10.2: The core pool size for the ordered thread pool, if its in use.
`producerPoolEnabled`	`true`	Camel 2.10.4/Camel 2.11: Producer only. Whether producer pool is enabled or not. Important: Do not turn this off, as the pooling is needed for handling concurrency and reliable request/reply.
`producerPoolMaxActive`	`-1`	Camel 2.10.3: Producer only. Sets the cap on the number of objects that can be allocated by the pool (checked out to clients, or idle awaiting checkout) at a given time. Use a negative value for no limit.
`producerPoolMinIdle`	`0`	Camel 2.10.3: Producer only. Sets the minimum number of instances allowed in the producer pool before the evictor thread (if active) spawns new objects.
`producerPoolMaxIdle`	`100`	Camel 2.10.3: Producer only. Sets the cap on the number of "idle" instances in the pool.
`producerPoolMinEvictableIdle`	`30000`	Camel 2.10.3: Producer only. Sets the minimum amount of time (value in millis) an object may sit idle in the pool before it is eligible for eviction by the idle object evictor.
`bootstrap Configuration`	`null`	Camel 2.12: Consumer only. Allows to configure the Netty ServerBootstrap options using a `org.apache.camel.component.netty.NettyServerBootstrapConfiguration` instance. This can be used to reuse the same configuration for multiple consumers, to align their configuration more easily.
`bossPoll`	`null`	Camel 2.12: To use a explicit `org.jboss.netty.channel.socket.nio.BossPool` as the boss thread pool. For example to share a thread pool with multiple consumers. By default each consumer has their own boss pool with 1 core thread.
`workerPool`	`null`	Camel 2.12: To use a explicit `org.jboss.netty.channel.socket.nio.WorkerPool` as the worker thread pool. For example to share a thread pool with multiple consumers. By default each consumer has their own worker pool with 2 x cpu count core threads.
`networkInterface`	`null`	Camel 2.12: Consumer only. When using UDP then this option can be used to specify a network interface by its name, such as `eth0` to join a multicast group.
`udpConnectionlessSending`	`false`	Camel 2.15: Producer only. This option supports connection less udp sending which is a real fire and forget. A connected udp send receive the PortUnreachableException if no one is listen on the receiving port.

Registry based Options

Codec Handlers and SSL Keystores can be enlisted in the Registry, such as in the Spring XML file.
The values that could be passed in, are the following:

< tr>

Name	Description
`passp hrase`	password setting to use in order to encrypt/decrypt payloads sent using SSH
`keyStoreFormat`	keystore format to be used for payload encryption. Defaults to "JKS" if not set
`securityProvider`	Security provider to be used for payload encryption. Defaults to "SunX509" if not set.
`keyStoreFile`	deprecated: Client side certificate keystore to be used for encryption
`trustStoreFile`	deprecated: Server side certificate keystore to be used for encryption
`keyStoreResource`	Camel 2.11.1: Client side certificate keystore to be used for encryption. Is loaded by default from classpath, but you can prefix with `"classpath:"`, `"file:"`, or `"http:"` to load the resource from different systems.
`trustStoreResource`	Camel 2.11.1: Server side certificate keystore to be used for encryption. Is loaded by default from classpath, but you can prefix with `"classpath:"`, `"file:"`, or `"http:"` to load the resource from different systems.
`sslHandler`	Reference to a class that could be used to return an SSL Handler
`encoder`	A custom `ChannelHandler` class that can be used to perform special marshalling of outbound payloads. Must override `org.jboss.netty.channel.ChannelDownStreamHandler`.
`encorders`	A list of encoders to be used. You can use a String which have values separated by comma, and have the values be looked up in the Registry. Just remember to prefix the value with # so Camel knows it should lookup.
`decoder`	A custom `ChannelHandler` class that can be used to perform special marshalling of inbound payloads. Must override `org.jboss.netty.channel.ChannelUpStreamHandler`.
`decoders`	A list of decoders to be used. You can use a String which have values separated by comma, and have the values be looked up in the Registry. Just remember to prefix the value with # so Camel knows it should lookup.

Important: Read below about using non shareable encoders/decoders.

Using non shareable encoders or decoders

If your encoders or decoders is not shareable (eg they have the @Shareable class annotation), then your encoder/decoder must implement the org.apache.camel.component.netty.ChannelHandlerFactory interface, and return a new instance in the newChannelHandler method. This is to ensure the encoder/decoder can safely be used. If this is not the case, then the Netty component will log a WARN when
an endpoint is created.

The Netty component offers a org.apache.camel.component.netty.ChannelHandlerFactories factory class, that has a number of commonly used methods.

Sending Messages to/from a Netty endpoint

Netty Producer

In Producer mode, the component provides the ability to send payloads to a socket endpoint
using either TCP or UDP protocols (with optional SSL support).

The producer mode supports both one-way and request-response based operations.

Netty Consumer

In Consumer mode, the component provides the ability to:

listen on a specified socket using either TCP or UDP protocols (with optional SSL support),
receive requests on the socket using text/xml, binary and serialized object based payloads and
send them along on a route as message exchanges.

The consumer mode supports both one-way and request-response based operations.

Headers

The following headers are filled for the exchanges created by the Netty consumer:

Header key	Class	Description
`NettyConstants.NETTY_CHANNEL_HANDLER_CONTEXT` / `CamelNettyChannelHandlerContext`	`org.jboss.netty.channel.ChannelHandlerContext`	`ChannelHandlerContext` instance associated with the connection received by netty.
`NettyConstants.NETTY_MESSAGE_EVENT` / `CamelNettyMessageEvent`	`org.jboss.netty.channel.MessageEvent`	`MessageEvent` instance associated with the connection received by netty.
`NettyConstants.NETTY_REMOTE_ADDRESS` / `CamelNettyRem oteAddress`	`java.net.SocketAddress`	Remote address of the incoming socket connection.
`NettyConstants.NETTY_LOCAL_ADDRESS` / `CamelNettyLocalAddress`	`java.net.SocketAddress`	Local address of the incoming socket connection.
