Smooth dataflow curve & Half CPU usage for client

_(Strongly Recommended for upgrading)_

  1. Smooth dataflow curve by setting MaxStreamWindowSize to sockbuf(hidden).
  2. Half CPU usage by using recv() syscall instead of recvfrom() syscall. (client only)

_（强烈建议升级）_

  1. 设置MaxStreamWindowSize 值为 sockbuf(隐)，以期望平滑数据传输曲线。
  2. 调整UDP接收的系统调用，recvfrom() 改为 recv()，降低客户端CPU消耗(一半以上)。

before

改之后:

Cumulative Non-Critical Updates

Updates(20160808):

  • Add hidden parameters
    • sockbuf: send/recv buffer size of udp sockets, default to 4MB.(macOS limit, pre: 16MB.)
    • keepalive: NAT keepalive interval(in seconds) to prevent your router from removing port mapping, default to 10s.(pre:5s.)
  • Optimized Algorithms:
    • If TX queue is not empty, ping packet is unnecessary to fire.
    • FEC search range is more precise.
    • PAWS detection is not required in markData() of FEC.
    • CLI parameters are parsed only once after startup. (provided by @buaazp)
    • _Explicitly dereference data immediately, hopefully this would lower memory usage. (Update: 20160809)_
    • _Do not update RTT for recovered packets from FEC. (Update: 20160810)_
  • API optimize
    • Listener has it's own SetDSCP() function.

累计非关键更新(20160808):

  • 增加隐藏参数
    • sockbuf：用于调整udp socket的收发缓冲区大小, 默认值为4MB。(macOS限制, 前值为16MB。)
    • keepalive：用于调整NAT keepalive的间隔时间，避免路由器清除端口映射。(默认值10s, 前值5s。)
  • 优化的算法:
    • 如果传输队列非空，则不需要发送ping包。
    • FEC更精确的搜索范围。
    • FEC的markData()不需要检测PAWS。
    • 启动后只解析一次命令行参数。（@buaazp提供）
    • _数据队列显式的去引用，希望能降低内存使用。(Update: 20160809)_
    • _RTT计算优化，不计入通过FEC纠错而来的RTT。(Update: 20160810)_
  • API优化
    • Listener实现独立的SetDSCP()函数。

improve network latency by introducing stream mode

_Update 20160726: recompiled with go1.7rc3 && optimize ikcp_send for stream mode_
_Update 20160803: recompiled with go1.7rc5_

_Strongly Recommended for Upgrading_

the default packet mode operations of kcp would introduce HOL-blocking for a single message; by eliminating message boundary with _stream mode_, this problem has relived.

kcp默认包模式的传输会引入单包的Head Of Line 阻塞问题，因此通过修改kcp，并在kcp-go中增加了stream模式缓解此问题，以降低网络延迟。（官方已同步）

Compression with Snappy (The first compression enabled release)

_CAUTION: NOT COMPATIBLE WITH PREVIOUS RELEASES WITH DEFAULT SETTINGS._

_MAKE SURE TO VERIFY YOUR MD5 HASH BEFORE DEPLOY._
_STRONGLY RECOMMENDED FOR UPGRADING._

  1. Add google snappy compression for transport layer to _accelerate_ data transfer(_enabled by default_) , use -nocomp on both side to disable.
  2. Compression has no effect on _already encrypted_ data stream.

_注意：默认与以前版本不兼容（两端需同时升级）_

_部署之前请务必确认您的MD5哈希值_
_强烈建议升级_

  1. 使用google snappy算法对传输层做数据流压缩（_默认开启），_用于加速数据传输。
  2. 注意: 对于承载的数据**已经加密的**，没有明显效果。

SNMP Millstone Version

_compiler: go version go1.7beta1 darwin/amd64_
_MAKE SURE TO VERIFY YOUR MD5 HASH BEFORE DEPLOY_
_EVERYONE IS SUGGESTED TO UPGRADE_

  1. Reduce memory usage by avoiding make on fec group
  2. Release freebsd binary version
  3. Expose SetNoDelay() function for future manual control
  4. Add SNMP to dump information, kill -SIGUSR1 pid to print
  5. Pipeline ReadFromUDP() for faster receiving of UDP Packets
  6. Fix parse_ack() for _too many fast resend_
  7. Adjust yamux max window size for better streaming of UHD video
  8. _Randomize_ ping packet length and content
  9. Add hidden parameters for manual control of SetNoDelay(), eg:
    -mode manual -nodelay 1 -resend 3 -nc 1 -interval 20
