KCP C#版

开箱即用。也可以使用 Nuget 搜索。

👁 Nuget

Feature：

  • 异步API标准接口 IKcpIO.cs
    • ValueTask Recv(IBufferWriter<byte> writer, object option = null);
    • ValueTask Output(IBufferWriter<byte> writer, object option = null);
    • 附带一个基本实现。KcpIO.cs
  • kcpSegment泛型化，可由用户自定义高性能实现。
    • KcpCore<Segment> where Segment : IKcpSegment
    • KcpIO<Segment> : KcpCore<Segment>, IKcpIO where Segment : IKcpSegment
    • Kcp<Segment> : KcpCore<Segment> where Segment:IKcpSegment

c: skywind3000 KCP
go: xtaci kcp-go

说明：

  • 内部使用了unsafe代码和非托管内存，不会对gc造成压力。
  • 支持用户自定义内存管理方式,如果不想使用unsafe模式,可以使用内存池.
  • 对于output回调和TryRecv函数。使用RentBuffer回调，从外部分配内存。请参考IMemoryOwner用法。
  • 支持Span<byte>

线程安全

简单的说：
不能在线程1调用Recv/Update时，线程2也在调用Recv/Update。函数内部使用大量共享数据结构，如果加锁严重影响性能。
可以在线程1调用Send/Input时，线程2也在调用Send/Input。函数内部有锁。

  • 可以在任意多线程同时调用Send 和 Input。
    多线程同时发送消息是安全的，可以放心的在异步函数中发送消息。
  • 但不可以多个线程同时调用Recv 和 Update。
    同名方法仅支持一个线程同时调用，否则会导致多线程错误。

测试：

在UnitTestProject1路径下执行 dotnet test 可进行多框架测试。（需要安装dotnetcoreSDK）

相对C版的一些变化：

差异变化 C版 C#版
数据结构
acklist 数组 ConcurrentQueue
snd_queue 双向链表 ConcurrentQueue
snd_buf 双向链表 LinkedList
rcv_buf 双向链表 LinkedList
rcv_queue 双向链表 List
-------------- -------------- --------------
回调函数 增加了RentBuffer回调，当KCP需要时可以从外部申请内存。
多线程 增加了线程安全。
流模式 由于数据结构变动，流模式不会填充当前未发送的最末的数据包。
interval最小间隔 10ms 0ms(在特殊形况下允许CPU满负荷运转)
-------------- -------------- --------------
API变动
增加大小端编码设置。默认小端编码。
增加TryRecv函数，当可以Recv时只peeksize一次。
ikcp_ack_push 删除了此函数（已内联）
ikcp_ack_get 删除了此函数（已内联）
