the mobile station and GGSN (gatewayuplssupportnode, gateway GPRS node) establishes a logical path for data transmission. It can be seen that the activation process is the key to system implementation, which is implemented by the central controller software. The activation of the grouped data protocol involves multiple network protocols, such as www.2cto.com, PPP, LCP (LinkControlProtocol), NCP (NetworkControlProtocol, Network Control

Video image transmission has the following characteristics: 1 requirements for small transmission delay, high real-time, 2 transmission flow, requiring high transmission efficiency; 3 allow transmission errors or data loss on certain programs. According to the above characteristics, it is more ideal to use UDP protocol to transmit video relative to TCP protocol. UDP is the abbreviation of User Datagram

Mobile device Management (MDM) and OMA (OTA) DM Protocol Wizard (ii)--WAP Protocol (1)On the "Mobile Device Management (MDM) and OMA (OTA) DM Protocol Wizard (i)"16. Can I access WiMAX devices directly from the Web server?See "WAP Protocol (1)--6th WAP Network Deployment" in this article17. Can I use TCP instead of WDP

First, the introduction The Protocol deals with properties and methods that act like abstract classes in Java, and the types in swift implement agreed properties and methods by complying with the protocol. The protocols in Swift are declared using the Protocol keyword. The protocol in Swift also has a very interesting

Redis Communication Protocol (protocol) This document is translated from: Http://redis.io/topics/protocol. The Redis protocol compromises between the following three goals: ease of implementation can be efficiently analyzed by computer (parse) can easily be read by humans to understand the network layer The client and

TPC/IP Protocol is a Transport layer protocol, which mainly solves how data is transmitted in the network, and HTTP is the application layer protocol, which mainly solves how to wrap the data. regarding the relationship between TCP/IP and HTTP protocol, the network has a relatively easy to understand: "When we transmit

One, the distinction between communication and communication protocol:1, the traditional meaning of "communication" mainly refers to telephone, telegraph, telex. The "message" of the communication means the messages, and the media messages are passed from one end to the other through the communication network. The content of media message is mainly voice, text, picture and video image. The composition of its network is mainly composed of electronic eq
