Socket.NoDelay プロパティ
アセンブリ: System (system.dll 内)
構文
/** @property */ public boolean get_NoDelay () /** @property */ public void set_NoDelay (boolean value)
Socket が Nagle アルゴリズムを使用する場合は false。それ以外の場合は true。既定値は false です。
Nagle アルゴリズムは、ソケットで最大 200 ミリ秒の間パケットをバッファリングし、それらを 1 パケットに結合して送信することによりネットワーク トラフィックを低減します。
NoDelay プロパティの使用方法を示すコード例を次に示します。
static void ConfigureTcpSocket(Socket tcpSocket) { // Don't allow another socket to bind to this port. tcpSocket.ExclusiveAddressUse = true; // The socket will linger for 10 seconds after // Socket.Close is called. tcpSocket.LingerState = new LingerOption (true, 10); // Disable the Nagle Algorithm for this tcp socket. tcpSocket.NoDelay = true; // Set the receive buffer size to 8k tcpSocket.ReceiveBufferSize = 8192; // Set the timeout for synchronous receive methods to // 1 second (1000 milliseconds.) tcpSocket.ReceiveTimeout = 1000; // Set the send buffer size to 8k. tcpSocket.SendBufferSize = 8192; // Set the timeout for synchronous send methods // to 1 second (1000 milliseconds.) tcpSocket.SendTimeout = 1000; // Set the Time To Live (TTL) to 42 router hops. tcpSocket.Ttl = 42; Console.WriteLine("Tcp Socket configured:"); Console.WriteLine(" ExclusiveAddressUse {0}", tcpSocket.ExclusiveAddressUse); Console.WriteLine(" LingerState {0}, {1}", tcpSocket.LingerState.Enabled, tcpSocket.LingerState.LingerTime); Console.WriteLine(" NoDelay {0}", tcpSocket.NoDelay); Console.WriteLine(" ReceiveBufferSize {0}", tcpSocket.ReceiveBufferSize); Console.WriteLine(" ReceiveTimeout {0}", tcpSocket.ReceiveTimeout); Console.WriteLine(" SendBufferSize {0}", tcpSocket.SendBufferSize); Console.WriteLine(" SendTimeout {0}", tcpSocket.SendTimeout); Console.WriteLine(" Ttl {0}", tcpSocket.Ttl); Console.WriteLine(" IsBound {0}", tcpSocket.IsBound); Console.WriteLine(""); }
static void ConfigureTcpSocket(Socket^ tcpSocket) { // Don't allow another socket to bind to this port. tcpSocket->ExclusiveAddressUse = true; // The socket will linger for 10 seconds after // Socket.Close is called. tcpSocket->LingerState = gcnew LingerOption(true, 10); // Disable the Nagle Algorithm for this tcp socket. tcpSocket->NoDelay = true; // Set the receive buffer size to 8k tcpSocket->ReceiveBufferSize = 8192; // Set the timeout for synchronous receive methods to // 1 second (1000 milliseconds.) tcpSocket->ReceiveTimeout = 1000; // Set the send buffer size to 8k. tcpSocket->SendBufferSize = 8192; // Set the timeout for synchronous send methods // to 1 second (1000 milliseconds.) tcpSocket->SendTimeout = 1000; // Set the Time To Live (TTL) to 42 router hops. tcpSocket->Ttl = 42; Console::WriteLine("Tcp Socket configured:"); Console::WriteLine(" ExclusiveAddressUse {0}", tcpSocket->ExclusiveAddressUse); Console::WriteLine(" LingerState {0}, {1}", tcpSocket->LingerState->Enabled, tcpSocket->LingerState->LingerTime); Console::WriteLine(" NoDelay {0}", tcpSocket->NoDelay); Console::WriteLine(" ReceiveBufferSize {0}", tcpSocket->ReceiveBufferSize); Console::WriteLine(" ReceiveTimeout {0}", tcpSocket->ReceiveTimeout); Console::WriteLine(" SendBufferSize {0}", tcpSocket->SendBufferSize); Console::WriteLine(" SendTimeout {0}", tcpSocket->SendTimeout); Console::WriteLine(" Ttl {0}", tcpSocket->Ttl); Console::WriteLine(" IsBound {0}", tcpSocket->IsBound); Console::WriteLine(""); }
