 extends org.apache.ignite.spi.communication.tcp.internal.TcpCommunicationConfigInitializer</pre>
 <div class="block"><tt>TcpCommunicationSpi</tt> is default communication SPI which uses
  TCP/IP protocol and Java NIO to communicate with other nodes.
  <p>
  To enable communication with other nodes, this SPI adds <a href="../../../../../../org/apache/ignite/spi/communication/tcp/TcpCommunicationSpi.html#ATTR_ADDRS"><code>ATTR_ADDRS</code></a> and <a href="../../../../../../org/apache/ignite/spi/communication/tcp/TcpCommunicationSpi.html#ATTR_PORT"><code>ATTR_PORT</code></a> local node
  attributes (see <a href="../../../../../../org/apache/ignite/cluster/ClusterNode.html#attributes--"><code>ClusterNode.attributes()</code></a>.
  <p>
  At startup, this SPI tries to start listening to local port specified by <code>TcpCommunicationConfigInitializer.setLocalPort(int)</code> method. If local
  port is occupied, then SPI will automatically increment the port number until it can successfully bind for listening.
  <code>TcpCommunicationConfigInitializer.setLocalPortRange(int)</code> configuration parameter controls maximum number of ports that SPI will try before it
  fails. Port range comes very handy when starting multiple grid nodes on the same machine or even in the same VM. In
  this case all nodes can be brought up without a single change in configuration.
  <p>
  This SPI caches connections to remote nodes so it does not have to reconnect every time a message is sent. By
  default, idle connections are kept active for <a href="../../../../../../org/apache/ignite/spi/communication/tcp/TcpCommunicationSpi.html#DFLT_IDLE_CONN_TIMEOUT"><code>DFLT_IDLE_CONN_TIMEOUT</code></a> period and then are closed. Use <code>TcpCommunicationConfigInitializer.setIdleConnectionTimeout(long)</code> configuration parameter to configure you own idle connection timeout.
  <h1 class="header">Failure Detection</h1>
  Configuration defaults (see Configuration section below and <a href="../../../../../../org/apache/ignite/configuration/IgniteConfiguration.html#getFailureDetectionTimeout--"><code>IgniteConfiguration.getFailureDetectionTimeout()</code></a>)
  for details) are chosen to make possible for communication SPI work reliably on most of hardware and virtual
  deployments, but this has made failure detection time worse.
  <p>
  If it's needed to tune failure detection then it's highly recommended to do this using <a href="../../../../../../org/apache/ignite/configuration/IgniteConfiguration.html#setFailureDetectionTimeout-long-"><code>IgniteConfiguration.setFailureDetectionTimeout(long)</code></a>. This failure timeout automatically controls the following
  parameters: <code>TcpCommunicationConfigInitializer.getConnectTimeout()</code>, <code>TcpCommunicationConfigInitializer.getMaxConnectTimeout()</code>, <code>TcpCommunicationConfigInitializer.getReconnectCount()</code>. If any of
  those parameters is set explicitly, then the failure timeout setting will be ignored.
  <p>
  If it's required to perform advanced settings of failure detection and <a href="../../../../../../org/apache/ignite/configuration/IgniteConfiguration.html#getFailureDetectionTimeout--"><code>IgniteConfiguration.getFailureDetectionTimeout()</code></a>
  is unsuitable then various <code>TcpCommunicationSpi</code> configuration parameters may be used.
  <h1 class="header">Configuration</h1>
  <h2 class="header">Mandatory</h2>
  This SPI has no mandatory configuration parameters.
  <h2 class="header">Optional</h2>
  The following configuration parameters are optional:
  <ul>
  <li>Address resolver (see <code>TcpCommunicationConfigInitializer.setAddressResolver(AddressResolver)</code></li>
  <li>Node local IP address (see <code>TcpCommunicationConfigInitializer.setLocalAddress(String)</code>)</li>
  <li>Node local port number (see <code>TcpCommunicationConfigInitializer.setLocalPort(int)</code>)</li>
  <li>Local port range (see <code>TcpCommunicationConfigInitializer.setLocalPortRange(int)</code></li>
  <li>Use paired connections (see <code>TcpCommunicationConfigInitializer.setUsePairedConnections(boolean)</code></li>
  <li>Connections per node (see <code>TcpCommunicationConfigInitializer.setConnectionsPerNode(int)</code>)</li>
  <li>Shared memory port (see <code>TcpCommunicationConfigInitializer.setSharedMemoryPort(int)</code></li>
  <li>Idle connection timeout (see <code>TcpCommunicationConfigInitializer.setIdleConnectionTimeout(long)</code>)</li>
  <li>Direct or heap buffer allocation (see <code>TcpCommunicationConfigInitializer.setDirectBuffer(boolean)</code>)</li>
  <li>Direct or heap buffer allocation for sending (see <code>TcpCommunicationConfigInitializer.setDirectSendBuffer(boolean)</code>)</li>
  <li>Count of selectors and selector threads for NIO server (see <code>TcpCommunicationConfigInitializer.setSelectorsCount(int)</code>)</li>
  <li>Selector thread busy-loop iterations (see <code>TcpCommunicationConfigInitializer.setSelectorSpins(long)</code></li>
  <li><code>TCP_NODELAY</code> socket option for sockets (see <code>TcpCommunicationConfigInitializer.setTcpNoDelay(boolean)</code>)</li>
  <li>Filter reachable addresses (see <code>TcpCommunicationConfigInitializer.setFilterReachableAddresses(boolean)</code> </li>
  <li>Message queue limit (see <code>TcpCommunicationConfigInitializer.setMessageQueueLimit(int)</code>)</li>
  <li>Slow client queue limit (see <code>TcpCommunicationConfigInitializer.setSlowClientQueueLimit(int)</code>)</li>
  <li>Connect timeout (see <code>TcpCommunicationConfigInitializer.setConnectTimeout(long)</code>)</li>
  <li>Maximum connect timeout (see <code>TcpCommunicationConfigInitializer.setMaxConnectTimeout(long)</code>)</li>
  <li>Reconnect attempts count (see <code>TcpCommunicationConfigInitializer.setReconnectCount(int)</code>)</li>
  <li>Socket receive buffer size (see <code>TcpCommunicationConfigInitializer.setSocketReceiveBuffer(int)</code>)</li>
  <li>Socket send buffer size (see <code>TcpCommunicationConfigInitializer.setSocketSendBuffer(int)</code>)</li>
  <li>Socket write timeout (see <code>TcpCommunicationConfigInitializer.setSocketWriteTimeout(long)</code>)</li>
  <li>Number of received messages after which acknowledgment is sent (see <code>TcpCommunicationConfigInitializer.setAckSendThreshold(int)</code>)</li>
  <li>Maximum number of unacknowledged messages (see <code>TcpCommunicationConfigInitializer.setUnacknowledgedMessagesBufferSize(int)</code>)</li>
  </ul>
  <h2 class="header">Java Example</h2>
  TcpCommunicationSpi is used by default and should be explicitly configured only if some SPI configuration parameters
  need to be overridden.
  <pre name="code" class="java">
  TcpCommunicationSpi commSpi = new TcpCommunicationSpi();

  // Override local port.
  commSpi.setLocalPort(4321);

  IgniteConfiguration cfg = new IgniteConfiguration();

  // Override default communication SPI.
  cfg.setCommunicationSpi(commSpi);

  // Start grid.
  Ignition.start(cfg);
  </pre>
  <h2 class="header">Spring Example</h2>
  TcpCommunicationSpi can be configured from Spring XML configuration file:
  <pre name="code" class="xml">
  &lt;bean id="grid.custom.cfg" class="org.apache.ignite.configuration.IgniteConfiguration" singleton="true"&gt;
          ...
          &lt;property name="communicationSpi"&gt;
              &lt;bean class="org.apache.ignite.spi.communication.tcp.TcpCommunicationSpi"&gt;
                  &lt;!-- Override local port. --&gt;
                  &lt;property name="localPort" value="4321"/&gt;
              &lt;/bean&gt;
          &lt;/property&gt;
          ...
  &lt;/bean&gt;
