什么是滑动窗口(Sliding Window) The Sliding Problem contains a sliding window which is a sub – list that runs over a Large Array which is an underlying collection of elements. 滑动窗口算法可以用以解决数组/字符串的子元素问题,它可以将嵌套的循环问题,转换为单循环问题,降低时间复杂度. 比如找最长的全为1的子数组长度.滑动窗口一般从第一个元…

TCP滑动窗口详解  http://lyjdamzwf.blog.163.com/blog/static/75206837201193373226/ TCP滑动窗口(Sliding Window)   滑动窗口协议可以用图四来形象表示. 图中我们已经将字节进行了1到11的编号.由接收者通告的窗口称为提议窗口(offered window),它覆盖了第4到第9个字节,意味着接收方已经确认了第3字节之前(包括第3字节)的数据,并且通告窗口的大小是6.窗口大小与确认的顺序号(acknowledged…

一.TCP状态转换图 下图对排除和定位网络或系统故障时大有帮助,也帮助我们更好的编写Linux程序,对嵌入式开发也有指导意义.    先回顾一下TCP建立连接的三次握手过程,以及关闭连接的四次握手过程:   1.建立连接协议(三次握手) (1)客户端发送一个带SYN标志的TCP报文到服务器.这是三次握手过程中的报文1. (2) 服务器端回应客户端的,这是三次握手中的第2个报文,这个报文同时带ACK标志和SYN标志.因此它表示对刚才客户端SYN报文的回应:同时又标志SYN给客户端,询问客户端是否准…

滑动窗口机制 滑动窗口协议的基本原理就是在任意时刻,发送方都维持了一个连续的允许发送的帧的序号,称为发送窗口:同时,接收方也维持了一个连续的允许接收的帧的序号,称为接收窗口.发送窗口和接收窗口的序号的上下界不一定要一样,甚至大小也可以不同.不同的滑动窗口协议窗口大小一般不同.发送方窗口内的序列号代表了那些已经被发送,但是还没有被确认的帧,或者是那些可以被发送的帧.下面举一个例子(假设发送窗口尺寸为2,接收窗口尺寸为1): 分析: ①初始态,发送方没有帧发出,发送窗口前后沿相重合.接收方0号窗口打…

TCP窗口机制 TCP header中有一个Window Size字段,它其实是指接收端的窗口,即接收窗口.用来告知发送端自己所能接收的数据量,从而达到一部分流控的目的. 其实TCP在整个发送过程中,也在度量当前的网络状态,目的是为了维持一个健康稳定的发送过程,比如拥塞控制.因此,数据是在某些机制的控制下进行传输的,就是窗口机制. 窗口缩放因子(Window Scaling) 以前,window size最大为2的16次方,为65535,随着宽带不断提高,65535字节已经小了,为了突破限制,便…

滑动窗口 滑动窗口(sliding windows algorithm)这种方法,专门用于解决区间解的问题.它在运算的时候,将解集放在窗口中,结束的时候比对是否符合预期.在运算的过程中,会对窗口的左右边缘进行操作(扩大.缩小).特别针对于线性输入解决,滑动窗口就很形象了. 30. Substring with Concatenation of All Words You are given a string, s, and a list of words, words, that are all…

Median is the middle value in an ordered integer list. If the size of the list is even, there is no middle value. So the median is the mean of the two middle value. Examples: [2,3,4] , the median is 3 [2,3], the median is (2 + 3) / 2 = 2.5 Given an a…

滑动窗口基础 滑动窗口常用来解决求字符串子串问题,借助map和计数器,其能在O(n)时间复杂度求子串问题.滑动窗口和双指针(Two pointers)有些类似,可以理解为往同一个方向走的双指针.常用滑动窗口代码框架如下: //3. Longest Substring Without Repeating Characters int lengthOfLongestSubstring(string s) { vector<,); //用于对窗口内的各个字符计数 ,end=,res=; //窗口计数器…
