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。
