way to implement is the UDP mode. UDP (user Datagram Protocol), Chinese meaning is the User Datagram protocol, similar to texting, is a cheap way of communication, using this method without establishing a dedicated virtual connection, because there is no need to establish a dedicated connection, so the pressure on the server is much smaller than TCP , so it is also a common way of network programming.

The company recently bought a GSM SMS cat pool for texting. Encountered many problems on the way, now summarize the problems encountered.1. First GSM comes with a software for database development, long and short letter server. According to the corresponding rules, the data is stored in the table, and then the short and long message server will automatically send SMS. According to the customer service to the data set of processes to go down, stumbling

model. The construction of the model is believed to be casual Baidu a bit to know. Here I'll talk about the difference between TCP and UDP:①TCP is a connection-based protocol, which means that a reliable connection must be established with the other party before the data is formally sent and received.②UPD is the protocol that corresponds to TCP. It is a non-connected protocol that does not establish a connection with the other, but sends the packet in the past directly.We make a metaphor, TCP i

First, create a common interface between the two:
Public interface Sender {public
void Send ();
}
Second, create the implementation class:
public class MailSender implements Sender {
@Override public
void Send () {
System.out.println () Mailsender! ");
}
}
public class Smssender implements Sender {

Note that a program executes two times, resulting in two mutually isolated processes.Concurrency and parallelismParallel: Run concurrently, only with multiple CPUs to achieve parallel concurrency: pseudo-parallel, which appears to be running concurrently. A single cpu+ multi-channel technology can be implemented concurrently.
