sdp transmission

WCF uses messages as the only means of communication. It supports different Message Exchange modes (MEP: Message Exchange Pattern). The following are typical MEP types: one-Way, Request/Reply, and Duplex. The message is sent to the transport layer by the channel layer of WCF and sent to the destination through the corresponding transmission protocol. For TCP, it can provide a duplex channel, so it can provide native support for the above three MEP pro

Network transmission protocol and http protocol, transmission http protocolOverview: it refers to the constraints and specifications for communication between the server and the client. The data interaction between the client and the server is not disorganized and must follow (based on) certain specifications. Common protocols: A) HTTP and HTTPS Hypertext Transfer Protocol B) FTP File Transfer Protocol c) S

In section c #, we discussed the reliable transmission of udp packets (packet group transmission). However, the problem with the previous program is that the data is relatively large, A Message class has 2048B after serialization, and the actual data volume is only 50B, which indicates that the data is very effective. In this way, when too many packets are transmitted, the efficiency will be greatly reduced

What is the length of Coaxial Transmission compared with that of twisted pair wires? 1. Coaxial Transmission Line is a high-quality broadband shielded Transmission Line [Excellent]: low transmission attenuation. [Broadband]: the current product level in China has already reached 0 ~ 20Gz; twisted pair

(19th) Use block for message transmission and block message transmission Messages are transmitted between two classes, generally through a proxy or block. It is troublesome to write the proxy and the block is relatively simple. However, the block must pay special attention to the memory leakage problem, note that there must be weak references between self and block. The following describes how to use block

Event transmission and corresponding chain, event transmission chain Aside from the title above, This article focuses on how the system finds the control that needs to respond to the touch event when you touch the screen of your mobile phone, and the control's response to the touch event First, find the process to respond to the touch Event Control: the touch event is first detected by the message loop mech

Transmission of Struts2 and jqGrid parameters, and transmission of struts2jqgrid Recently, jqGrid was used in the project to display data. However, I have never understood how data is transmitted. In jqGrid, The rowNum parameter defines how many rows of data are displayed on each page, while in Action, the rows attribute defines the number of rows displayed on each page. Therefore, I have never understood

(usually home router), fill in the router password, click the blue button below, wait about 30 seconds, until the button becomes successful, if more than 1 minutes has not changed, Cliff is your password is wrong, or the account selected and password mismatch. 4.5 Successful people go ahead, return to the main interface4.6 Click on the network mode, for example, if the icon below the device online is a picture state, then the connection is successful, if the gray advanced bar in the rotation, i

Logu P2661 information transmission and logu p2661 Information Transmission This question has been done a long time ago. After a few months, I still don't know about it. First, consider each person as a node and generate a directed graph from the side that each person wants to tell him. Obviously, if a person is not on the ring, then it will never be able to hear his own information; if a person is on the r
