Provides full - screen visualization of network traffic . experiment with these tips and techniques to increase the performance of your sockets applications , including reducing transmit latency by disabling the nagle algorithm , increasing bandwidth utilization of a socket through buffer sizing , reducing system call overhead by minimizing the number of system calls , and tuning the linux tcp ip stack with tunable kernel parameters 尝试使用本文中介绍的技巧和技术来提高socket应用程序的性能，包括通过禁用nagle算法来减少传输延时，通过设置缓冲区的大小来提高socket带宽的利用，通过最小化系统调用的个数来降低系统调用的负载，以及使用可调节的内核参数来优化linux的tcp / ip栈。
For the reduced system , the mean square criterion of stochastic melnikov process is derived to give the critical values of the probable onset of chaos and the conclusion is that the critical value turns from increase to decrease as the amplitude of weiner process increases in the interested parameter range 然后重点讨论了平均系统，经过推导得出相应的随机melnikov过程，用均方值准则导出随机系统可能产生混沌运动的临界条件，由此得到了在一定的参数范围内，随着weiner过程强度参数值的增大，混沌的临界激励幅值先递减继而递增。
