the generation of the sending sequence of packets, continuously adjusts the sending sequence, realizes the flow control and data integrity.Network layerThen send the data segment sent to the network layer, in the network layer is packaged, so encapsulated on the network layer of Baotou, Baotou contains the source and destination IP address, the layer of data transmission unit is called Packet. The network layer is responsible for transferring such pa

ACTIVEMQ the process of sending and receiving messages is similar to the JDBC Operations database: First create the Connection connection object, then the session object, and then create producer, Consumer, Objects such as message, except that ACTIVEMQ connection objects are generated through the Activemqconnectionfactory factory. Here are the test code for some scenarios. Define some constant data, which is also useful in the following example User name private final static string USERNAME = ac

-Ethernet router and a four-port small switch, and its WAN port is connected to the Internet, the LAN port is connected to the Intranet for differentiation.A route is the act of transmitting information from the source to the destination. In terms of image, the information package is like a person who wants to go to a specific location. routing is the process of selecting a path for this person. The route table is like a map marking various routes. Th
