scalability. Extended XMPP can address the needs of users by sending extended information, as well as applications such as content publishing systems and address-based services at the top of XMPP. Furthermore, XMPP contains software protocols for the server side to communicate with the other, making it easier for developers to build client applications or to add functionality to a system that is well equipped.

I. Summary This article compares the transmission performance of five communication protocols, including RMI, Hessian, burlap, httpinvoker, and Web Service, in different data structures and data volumes. RMI is a remote communication protocol provided by the Java language. It is stable and efficient and is the basis of EJB. But it can only be used in Java Progra

protocols since HTTP and SMTP. Advantages of SIP: Web-like scalable open communication With SIP, service providers can select standard components at will to quickly control new technologies. Regardless of the number of media content and participants, users can find and contact each other. SIP negotiates sessions so that all participants can agree on and modify session functions. It can even add, delete, o
