.net core輕量級高性能通訊組件BeetleX 頂 原

BeetleX

beetleX是基於dotnet core實現的輕量級高性能的TCP通訊組件，使用方便、性能高效和安全可靠是組件設計的出發點！開發人員可以在Beetlx組件的支持下快帶地構建高性能的TCP通訊服務程序，在安全通訊方面只需要簡單地設置一下SSL信息即可實現可靠安全的SSL服務。

使用方便性

beetleX網絡流讀寫是基於Stream標準來構建，僅僅基於Stream的基礎讀寫對於應用者來說還是過於繁瑣；組件爲了更方便進行網絡數據處理在Stream的基礎之上擴展了一系列的讀寫規則：ReadLine、ReadInt、WriteLine、WriteInt等一系列簡便方法，在這些方法的支持下使用者就可以更輕鬆地處理數據；爲了在網絡通訊中更好的兼容其他平臺協議以上方法都兼容Big-Endian和Little-Endian不同方式。爲了更好地利用現有序列化組件，組件通過IPacket接口規範消息擴展，通過實現不同的Packet解釋器，即可以實現基於Protobuf,json和Msgpack等方式的對象數據傳輸。

高性能特性

beetleX的高性能是建立在內部一個數據流處理對象PipeStream，它是構建在Stream標準之上；它和.NET內置的NetworkStream最大的差別是PipeStream的讀寫基於SocketAsyncEventArgs實現，這正是在編寫高性能網絡數據處理所提倡的模式。PipeStream不僅在網絡數據處理模式上有着性能的優勢，在內存讀寫上和MemoryStream也有着很大的區別；由於PipeStream的內存塊是以一個基於鏈表的SocketAsyncEventArgs Buffer 組成，因此PipeStream在寫入大數據的情況並不存在內存擴容和複製的問題；因爲PipeStream基礎內存是SocketAsyncEventArgs Buffer，所以在數據和網絡緩存讀寫並不存在內存塊複製過程。如果在應用中中使用PipeStream相應的BinaryReader和IBinaryWriter讀寫規範，那大部分數據處理基本不存在內存複製過程，從而讓數據處理性能更高效。

以下是PipeStream的結構： 

性能

beetleX的性能到底怎樣呢，以下簡單和DotNetty進行一個網絡數據交換的性能測試,分別是1K,5K和10K連接數下數據請求併發測試

DotNetty測試代碼

        public override void ChannelRead(IChannelHandlerContext context, object message)
        {
            var buffer = message as IByteBuffer;
            context.WriteAsync(message);
        }

Beetlex 測試代碼

        public override void SessionReceive(IServer server, SessionReceiveEventArgs e)
        {
            server.Send(e.Stream.ToPipeStream().GetReadBuffers(), e.Session);
            base.SessionReceive(server, e);
        }

測試結果

1K connections

5K connections

10K connections

構建TCP Server

    class Program : ServerHandlerBase
    {
        private static IServer server;

        public static void Main(string[] args)
        {
            NetConfig config = new NetConfig();
            //ssl
            //config.SSL = true;
            //config.CertificateFile = @"c:\ssltest.pfx";
            //config.CertificatePassword = "123456";
            server = SocketFactory.CreateTcpServer<Program>(config);
            server.Open();
            Console.Write(server);
            Console.Read();
        }
        public override void SessionReceive(IServer server, SessionReceiveEventArgs e)
        {
            string name = e.Stream.ToPipeStream().ReadLine();
            Console.WriteLine(name);
            e.Session.Stream.ToPipeStream().WriteLine("hello " + name);
            e.Session.Stream.Flush();
            base.SessionReceive(server, e);
        }
    }

構建TCP Client

    class Program
    {
        static void Main(string[] args)
        {
            TcpClient client = SocketFactory.CreateClient<TcpClient>("127.0.0.1", 9090);
            //ssl
            //TcpClient client = SocketFactory.CreateSslClient<TcpClient>("127.0.0.1", 9090, "localhost");
            while (true)
            {
                Console.Write("Enter Name:");
                var line = Console.ReadLine();
                client.Stream.ToPipeStream().WriteLine(line);
                client.Stream.Flush();
                var reader = client.Read();
                line = reader.ToPipeStream().ReadLine();
                Console.WriteLine(line);
            }
            Console.WriteLine("Hello World!");
        }
    }

異步Client

    class Program
    {
        static void Main(string[] args)
        {
            AsyncTcpClient client = SocketFactory.CreateClient<AsyncTcpClient>("127.0.0.1", 9090);
            //SSL
            //AsyncTcpClient client = SocketFactory.CreateSslClient<AsyncTcpClient>("127.0.0.1", 9090, "serviceName");
            client.ClientError = (o, e) =>
            {
                Console.WriteLine("client error {0}@{1}", e.Message, e.Error);
            };
            client.Receive = (o, e) =>
            {
                Console.WriteLine(e.Stream.ToPipeStream().ReadLine());
            };
            var pipestream = client.Stream.ToPipeStream();
            pipestream.WriteLine("hello henry");
            client.Stream.Flush();
            Console.Read();
        }
    }

實現一個Protobuf對象解釋器

    public class Packet : FixedHeaderPacket
    {
        public Packet()
        {
            TypeHeader = new TypeHandler();
        }

        private PacketDecodeCompletedEventArgs mCompletedEventArgs = new PacketDecodeCompletedEventArgs();

        public void Register(params Assembly[] assemblies)
        {
            TypeHeader.Register(assemblies);
        }

        public IMessageTypeHeader TypeHeader { get; set; }

        public override IPacket Clone()
        {
            Packet result = new Packet();
            result.TypeHeader = TypeHeader;
            return result;
        }

        protected override object OnReader(ISession session, PipeStream reader)
        {
            Type type = TypeHeader.ReadType(reader);
            int bodySize = reader.ReadInt32();
            return reader.Stream.Deserialize(bodySize, type);
        }

        protected override void OnWrite(ISession session, object data, PipeStream writer)
        {
            TypeHeader.WriteType(data, writer);
            MemoryBlockCollection bodysize = writer.Allocate(4);
            int bodyStartlegnth = (int)writer.CacheLength;
            ProtoBuf.Meta.RuntimeTypeModel.Default.Serialize(writer.Stream, data);
            bodysize.Full((int)writer.CacheLength - bodyStartlegnth);
        }
    }
