这个问题乍看之下有点难以回答,但是其实答案十分简单,因为一个 connection 如果在一个 end point 上处于close wait,那么必然在另一个end point上是处于time wait状态,而一个 tcp connection 是由上述提到的一个四元组所标志的,自然只要一个 end point 能够解决 wandering 包的问题即可,所以close wait自然不需要像ti...
线程进入Timed_waiting状态,等待2秒后恢复到Runnable状态。 另一个示例代码演示了如何使用Object.wait(long timeout)方法使线程进入Timed_waiting状态: publicclassTimedWaitingExample2{publicstaticvoidmain(String[]args){finalObjectlock=newObject();Runnablerunnable=()->{synchronized(lock){try{System.out.println("...
Object.wait(long timeout):使当前线程等待,直到其他线程调用此对象的 notify() 方法或 notifyAll() 方法,或者经过指定的时间量。 LockSupport.parkNanos(long nanos) 和LockSupport.parkUntil(long deadline):这些是更底层的线程阻塞工具,用于在指定的时间或纳秒数内阻塞当前线程。 ScheduledExecutorService 中的任务调...
LISTENING:指TCP正在监听端口,可以接受链接 TIME_WAIT: 指连接已准备关闭。表示收到了对方的FIN报文,并发送出了ACK报文,就等2MSL后即可回到CLOSED可用状态了。如果FIN_WAIT_1状态下,收到了对方同时带FIN标志和ACK标志的报文时,可以直接进入到TIME_WAIT状态,而无须经过FIN_WAIT_2 状态。 FIN_WAIT_1: 这个状态要...
在看tcp_timewait_state_process()函数中的处理之前,需要先看一看不同的返回值会对应什么样的处理。 如果返回值是TCP_TW_SYN,则说明接收到的是一个“合法”的SYN包(也就是说这个SYN包可以接受),这时会首先查找内核中是否有对应的监听套接字,如果存在相应的监听套接字,则会释放TIME_WAIT状态的传输控制结构,跳转...

Currently, if you specify the wait time as a timestamp, Step Functions considers the time value up to seconds and truncates milliseconds. SecondsPath(Optional, JSONPath only) A time, in seconds, to wait before beginning the state specified in theNextfield, specified using apathfrom the state...
The TIME_WAIT state is twice the MSL, this allows MSL seconds for a packet in one direction to be lost, and another MSL seconds for the reply to be lost. ... The 2MSL timer makes the client wait for a duration that is enough time for an ACK to be lost (one SML) and a FIN to...
