This will make the Universal Port a very light weight component since it will only have to read the first header/ line of the message and then forward the message to the appropriate protocol listener in the body of the ESB. 这将使通用端口成为一个非常轻量型的组件,因为它只需读取消息的第一个头部/行,然后将消息转发给ESB主体中合适的协议监听器。
Each TCP session has a destination port number in the TCP header. 每个TCP会话在TCP报头中有一目的端口号。
When a TCP segment is received, the TCP router knows which port to pass it to by looking at the port number in the TCP header. 当接收到一个TCP段时,TCP路由器通过查看TCP报头中的端口号就知道向哪个端口传送包。
