Method and system thereof for realizing multicast based on user name system

Abstract

The invention provides a system for realizing the broadcast on the basis of a user name system, comprising a broadcasting source, a repeater, a broadcasting sink, a broadcasting controller and the user name system, wherein, the broadcasting source is an information source of generating the broadcasting information and is used for determining the broadcasting path and sending the broadcasting information and a broadcasting list recording the broadcasting path; the repeater is used for receiving the broadcasting list and the broadcasting information and copying the broadcasting information as well as transmitting the copied information to one or a plurality of appointed addresses according to the broadcasting list; the broadcasting sink is an information sink of receiving the broadcasting information and is used for sending a request of receiving the broadcasting information to the broadcasting source and acquiring the broadcasting information from the repeater closest to the broadcasting sink; the broadcasting controller controls the broadcasting network system and comprises functions such as the broadcasting list calculation and distribution; and the user name system is used for providing an inquired user name of the repeater and IP address information. The technical proposal which is based on a UNS is utilized to realize the broadcast, thereby having the characteristics of simplicity, convenience, high performance, easy updating and extending and multiple functions.

Description

technical field [0001] The invention relates to network technology, in particular to a method and system for realizing broadcasting based on a user name system. Background technique [0002] 1. The type of broadcast [0003] The logical address itself essentially expresses the information of a network interface point. Therefore, what is determined by the source IP address plus the destination IP address in an IP packet is generally the information transfer between two network interface points on the network. The information transmission of most websites in the network (such as the main WEB websites in the Internet) needs to adopt the point-to-multipoint communication method. This point-to-multipoint communication method realizes the following types of broadcast information transmission, and different types of broadcast transmission methods will have different requirements: [0004] Connection-type real-time broadcast (can be called "stream"). This kind of broadcast does no...

AI Technical Summary

Problems solved by technology

[0007] 2. The problem of point-to-point broadcasting

For example: if there are 10,000 users who want to order movies in a server at the same time, the video server is required to have the concurrent capability of 10,000 streams at the same time, which is a huge requirement for the processing capacity of the server. In the process, this kind of concurrent capability is difficult to make a profit

[0011] (2), resulting in a huge waste of network traffic

Its economic efficiency on the surface is only due to the dislocation of the current network business relationship, the increased traffic at the user terminal, and the fact that the monthly tariff method does not reflect any cost.

[0015] 3. Existing broadcasting technologies and their defects

[0018] The defect of this technology is that the multicast IP address is not only complicated to control, but more importantly, this technology itself confuses the level of problem solving

[0021] The defect of the above two technologies is that although the DNS-based mirror website and CDN technology are constantly improving in terms of versatility and intelligence, this process also shows the versatility and limitations of automation

But its flaws are also obvious: First, this kind of use is based on the premise that users can provide this service free of charge. If traffic billing is used, a complex benefit sharing mechanism is required, otherwise users will obviously not be willing to accept P2P The information transfer server in the network; the second is that because the user host providing the service will go online and offline arbitrarily, how to re-find the connection point in the middle of the service and maintain the stability of the service in the process is an essential challenge and obstacles
