The Wgscd-picked Rtp/rtcp (real-time transport protocol/real-time Transport Control Protocol) is based on UDP-derived protocols and adds control over real-time transmission. Commonly used for online transmission of real-time video data, such as remote video surveillance, video-on-demand. There is a book called "Multimedia Network Transmission Protocol" on the structure and principle of the 2 agreements to

USB Transport Type There are four types of endpoints in USB, which correspond to four different modes of transmission, namely control transmission, interrupt transmission, synchronous transmission and block transmission. 1 Control Transfer The read and write timing of the control transmission is as follows: A total of three phases, the setup phase, the data phase, and the state phase, where the data phase is optional, and each phase consists of thr

TCP: Transmission Control Protocol) The transport control protocol is a transport layer protocol that enables reliable data transmission in TCP/IP groups, and implements virtual connection services for applications through sequential response, forward packets when necessary. In combination with the IP protocol, TCP represents the core of the network protocol. Most network applications run on the same machin

China's IP routers have developed rapidly and their technology is also very mature. Many people may not understand the connection between IP Routers and SDH devices of the IP transport network, after reading this article, you must have gained a lot. I hope this article will teach you more things. In recent years, the broadband high-speed Internet, with the IP technology as the core and SDH or DWDM as the bearer, has developed rapidly. IP Over SDH is o

Summary Symptom After the transport, the transformation has a reference to the wrong source system. As a result, there may be no rules, which is an error (rstran 514: "No rules exist "). Dumps may also occur when the data transfer processes (dtps) are activated. Other terms After import, dump, DTP, data transfer process, source, development system, rstran 514, rstran514 Reason and prerequisites This problem is caused by a program error. Solution SAP

Link: HuangJing Idea: The most short-circuit variant of the output path .. This question lies in multiple groups of inquiries, so I personally think it is more secure to use Floyd. In addition, there is a toll in every city, so you can change the Loose Condition in Floyd .. What about the output path ?? I use the successor of the output starting point instead of the precursor to the end point .. Because we care about the smallest Lexicographic Order of paths and the successor of the starting poi

TCP/IP Note 3. Transport Layer (1) -- UDP, TCP 1. Transport Layer 1.1 two Protocols: TCP and UDP. (1) TCP: provides a reliable data transmission service. TCP is connection oriented and can communicate only after the link is established. (2) UDP: data is sent directly, and no matter whether the recipient is receiving or not, even if UDP cannot be delivered, no ICMP error message will be generated. 1.2 upper

Connection-oriented and connectionless protocols To provide different levels of quality assurance for different situations, the transport layer provides two prototype protocols: Connection-oriented protocol: a connection is established and maintained between communication computers, and the connection status is monitored during the communication process. In other words, each packet transmitted over the network will have a confirmation. the sender

The origin of the transport layer includes the MAC address and IP address. We can establish communication between any two hosts on the Internet. Many programs on the same host need to use the network. For example, you can browse the Web page and chat with friends online. When a packet is sent from the Internet, how do you know whether it indicates the content of the webpage or the content of online chat? That is to say, we also need a parameter to ind

Heavy game relatively light casual games, the content of the game more rich, more mature players, pay will more obvious, so 15 years is likely to usher in a serious high-paying players concentrated outbreak, heavy game market share will rise further.3. The time fragmentation feature of the hand tour is no longer obviousWith the game content o

They are more inclined to continue to use the power of technology to achieve growth, such as the earliest online application search, the establishment of the application gene pool, as well as white pea wash, model identification, 0 traffic download and other innovative features.

Now there are some cargo that should being delivered from the one city to another. The transportation fee consists of the parts:The cost of the transportation on the path between these cities, andA certain tax which'll be charged whenever any cargo passing through one city, except for the source and the destination Cities.You must write a program to find the route which
