NAT basic IP address conversion PrincipleIn general, the NAT address translation process is the conversion process between the "local address" and "Global Address", whether the packets are sent from the internal network to the external network, or from the external network to the internal network. The difference is that the network corresponding to the local address and global address is different, and the source and destination addresses of data pack

This article will detail the transfer process of the data in the network when the client browses the Web abc.com.For example, PC1 accesses a Web page located on the server through the HTTP protocol. So, how does the Web data be transmitted in the network? Here are the

Receive messagesIn JMS, the receipt of a message can be used in the following two ways:1. Synchronous mode: The message Subscriber calls the receive () method when the message is received synchronously. In receive (), the message does not arrive or until the specified time is reached, and the method blocks until the message is available.(1),
