如下图所示:来自于https://www.geeksforgeeks.org 1.源端口号(Source Port):16bits,该字段标识发送方应用程序的端口号。 2.目标端口号(Destination Port):16bits,该字段标识接收方应用程序的端口号。 3.序列号(Sequence Number):32bits,在连接建立(三次握手)后,该字段包含一个32位随机初始序列号/起始数据位,...
TCP 连接数限制 通过{Source IP, Source Port, Destination IP, Destination Port} 四元组确定唯一的 TCP 连接。 对于服务提供方:只需要一个暴露一个端口给客户端,即可接收无限数量的 TCP 连接,在不考虑内存的前提下,客户端的 IP, Port 只要不同即可。 对于客户端:连接数量限制在 2^16 - 1 内,即 65535 个...

This means that the data is sent and received as a stream of bytes(unlike UDP or IP that divides the bits into datagrams or packets). However, the network layer, that provides service for the TCP, sends packets of information not streams of bytes. Hence, TCP groups a number of bytes t...

and understand how they work together. We’ll discuss what each layer does and why it’s crucial for successful communication between two systems. By the end of this post, you’ll have a comprehensive knowledge of the five-layer protocols in TCP/IP and how they work. Let’s get started!
