Description

Broadcast cloud platform for transmitting instructions, real-time streams and file streams

Technical Field

The invention relates to the technical field of computer communication, in particular to a broadcast cloud platform for transmitting instructions, real-time streams and file streams.

Background

The core of the broadcast cloud is to solve the problems of bandwidth and flow cost. It first needs to guarantee establishment of business model, and the key issue of establishment is bandwidth cost. Cost analysis shows that when a server distribution mode is developed, the following steps are carried out: only the access bottleneck caused by the scale rise of the terminal can be solved, and the overall bandwidth cost cannot be reduced.

There are indeed commercial solutions to analyze the market through a large number of investigations: CDN (server delivery), PCDN (device side delivery), but there is a problem in applicability: the CDN cannot be applied in a private network environment required by customers, and the PCDN is mainly used for a mobile terminal of a mobile phone and does not support application on terminal equipment. Self-research by reference to business solutions through technical evaluation within the capability of companies currently developing research teams, decision to self-research solutions is taken by integrating various aspects of factor consideration.

The foregoing discussion of the background art is intended only to facilitate an understanding of the present invention. The discussion is not an acknowledgement or admission that any of the material referred to was or was part of the common general knowledge as at the priority date of the application.

Disclosure of Invention

The invention provides a broadcast cloud platform for transmitting instructions, real-time streams and file streams, which is characterized in that the cloud platform is connected among a content cloud, an equipment cloud, a distribution device and a user terminal and is used for transmitting the instructions, the real-time streams and the file streams.

The cloud platform comprises a service interface layer and a functional layer, wherein the service interface layer is used for connecting a service system to provide SDK access service.

The functional layer comprises four sub-modules, namely a file distribution center, a stream distribution center, an instruction communication service and a P2P communication service.

The sub-module of the file distribution center comprises a file distribution node network and a file distribution center, wherein the file distribution node network is composed of a plurality of file cache regions, and the file distribution center is used for monitoring and scheduling the file distribution nodes, auditing resources of a file flow channel and providing access configuration for an upper-layer service system.

The flow distribution center submodule comprises a flow distribution network and a flow distribution center, wherein the flow distribution network consists of a plurality of flow distribution nodes and a source station, and the flow distribution center is used for monitoring and scheduling the flow distribution nodes and the source station, auditing real-time flow channel resources and providing access configuration for an upper-layer service system.

The command communication service submodule comprises a command service center, a command transmission interface and a command communication interface, wherein the command communication service center is used for monitoring and managing the CSA and providing the command transmission interface of an upper-layer service system; and the instruction service access point is used for providing the access of the communication channel of the terminal equipment to which the service system belongs.

The P2P communication service submodule comprises a P2P communication server, and the P2P communication server provides a transmission channel for interconnection and intercommunication of all terminal equipment nodes of the broadcasting cloud; and the P2P distribution center is used for monitoring and scheduling the P2P distribution nodes, auditing P2P channel resources and providing access configuration for an upper-layer service system.

The present invention solves the following three problems:

to solve the problem 1: the public network and the private network are consistent in structure, and the platform supports a public network operation environment and a private network operation environment. The universal broadcast cloud platform uniformly adopts the access form of the domain name to the outside, and in general knowledge, the most general function of the domain name is to replace the access of a fixed IP, so that two problems are solved: 1. the access of the user is convenient, and a certain IP address does not need to be memorized; 2. the problem of complicated system access or product configuration change process caused by IP address change is avoided.

Under the large environment of the internet/mobile internet, the domain name service belongs to infrastructure, and the system of the whole industry utilizes the link of domain name resolution in design to solve the problem of universality. Most systems adopt a multi-service and distributed system design mode, different services are distinguished through different sub-level domain names, information obtained by utilizing a link of domain name resolution is used for matching processing of geographic regions, operators and access loads, and finally, server addresses meeting various conditions are given to an access terminal, so that the problem of an optimal access path is solved.

Under a platform service business model (including CDN, storage, live broadcast service, etc.), a platform service provider needs to perform corresponding service resource audit and access isolation for each customer, and in order to ensure uniform and seamless access to a scheme, a common practice in the industry is to use a mechanism of a client side system (business system) domain name plus CNAME record to perform processing.

The main principle is as follows: and the business system side configures the sub-level domain name needing service into the platform service, and the platform service provides the domain name address actually accessed. The business system side (client side) adds the sub-level domain name and the CNAME mapping of the domain name actually accessed by the platform side in the own domain name service platform. When the user of the client system accesses, the sub-level domain name of the service system is accessed, but the platform service domain name which is actually accessed corresponds to the server, and the platform party performs authentication, resource access and audit according to the sub-level domain name information in the request.

Under the private network environment, the whole framework can keep consistency in deployment and implementation through the self-built domain name service. Problem 2 is solved: the combined architecture design provides a platform instruction, real-time stream and file stream communication service.

In the framework design, each service (module) can independently provide services or can combine to provide services, and no coupling exists between the services (modules). TBC provides instruction transmission service of service system side, TBS provides real-time stream distribution service of service system side, TBF provides file distribution service of service system side, TBP provides communication service between service system side devices, TBPD combines with TBS to perform P2P real-time stream distribution service, TBPD combines with TBF to perform P2P file stream distribution service. And the transmission service based on TBP to realize other types of services can be realized on subsequent extension.

Problem 3 is solved: the technical scheme is used for reducing the traffic bandwidth occupation and the operation cost of the platform while realizing scale enlargement. The architecture design realizes communication based on equipment through TBP, reduces flow access of a business system side terminal to a cloud platform on file flow and real-time flow access by establishing a transmission network between the equipment, and realizes scale enlargement and mass flow access through network transmission solution between the terminals.
