Description
技术领域 technical field
本发明涉及一种流媒体技术，尤其涉及一种适合运营商应用的对等网络流媒体业务处理系统及方法，属于网络通信领域。The invention relates to a streaming media technology, in particular to a peer-to-peer network streaming media service processing system and method suitable for operators, and belongs to the field of network communication.
背景技术 Background technique
流媒体(Streaming Media)是指数据在网络上按时间先后次序传输和播放的连续音/视频数据流。与传统的播放方式不同，以流媒体方式播放节目时并不需要客户端下载整个节目文件，而是边接收边播放，并且只需将部分节目数据缓存，这样就节省了下载等待时间和存储空间。Streaming Media (Streaming Media) refers to the continuous audio/video data stream in which data is transmitted and played in chronological order on the network. Different from the traditional playback method, the client does not need to download the entire program file when playing the program in the streaming media mode, but plays it while receiving it, and only needs to cache part of the program data, which saves download waiting time and storage space .
随着对等网络(Peer-to-Peer，以下简称：P2P)技术的发展，P2P流媒体业务得到了广泛应用。P2P技术打破了传统的客户端/服务器模式，是一种基于对等节点非中心化服务的方案。在P2P网络中，每个节点的地位都是相同的，具备客户端和服务器双重特性，可以同时作为服务使用者和服务提供者，其中，节点可以为服务器或者客户端。P2P技术充分利用了对等节点的服务能力，能在较低的扩展成本下避免拥塞，为大量用户提供具备高实时性和容错性能的流媒体服务，为流媒体服务开辟了一条崭新的道路。With the development of Peer-to-Peer (Peer-to-Peer, hereinafter referred to as: P2P) technology, P2P streaming media services have been widely used. P2P technology breaks the traditional client/server model and is a solution based on peer-to-peer decentralized services. In a P2P network, each node has the same status, has the dual characteristics of client and server, and can serve as a service user and a service provider at the same time, where a node can be a server or a client. P2P technology makes full use of the service capabilities of peer-to-peer nodes, can avoid congestion at a lower expansion cost, and provides streaming media services with high real-time and fault-tolerant performance for a large number of users, opening up a new path for streaming media services.
现有技术中，P2P流媒体业务系统实现流媒体业务的方法是：用户登陆客户端，在频道门户点击节目后，由客户端向频道门户服务器发送节目标识获取请求，频道门户服务器将作为节目唯一标识的节目标识信息返回给客户端；客户端向节点索引服务器发送包括节目标识信息的节目数据请求，节点索引服务器查询出边缘服务器不存在节目标识信息对应的节目数据时，客户端根据节目标识信息向内容源服务器请求节目数据；内容源服务器将节目数据分片下发给各边缘服务器；各边缘服务器通知节点索引服务器更新节点列表，其中，节点列表中的节点包括边缘服务器与其它客户端；节点索引服务器向客户端返回更新后的节点列表；客户端根据更新后的节点列表，与其它客户端及各边缘服务器之间实现节目数据传输。In the prior art, the P2P streaming media service system implements the streaming media service as follows: the user logs in to the client, clicks on a program on the channel portal, and then the client sends a program identification acquisition request to the channel portal server, and the channel portal server will serve as the unique The marked program identification information is returned to the client; the client sends a program data request including the program identification information to the node index server, and when the node index server finds out that the edge server does not have program data corresponding to the program identification information, the client Request the program data from the content source server; the content source server sends the program data fragments to each edge server; each edge server notifies the node index server to update the node list, wherein the nodes in the node list include the edge server and other clients; the node The index server returns the updated node list to the client; the client implements program data transmission with other clients and edge servers according to the updated node list.
但是，现有技术中存在如下问题：现有的处理P2P流媒体业务的系统主要是由内容源服务器、节点索引服务器、频道门户服务器等各种业务提供类服务器、管理类服务器以及边缘服务器组成。该系统仅存在一套业务提供类服务器和管理类服务器，并且未对边缘服务器按区域进行划分，因此，无法实现P2P流媒体业务的分区域管理，对于运营商来讲这样的系统难于控制和管理；并且现有系统中由于未对边缘服务器按区域进行划分，客户端与边缘服务器之间进行节目数据传输时，所有的边缘服务器都可作为P2P流媒体业务中节目数据的提供方，这样不仅同一区域的客户端之间可以进行节目数据传输，不同区域的客户端同样可以进行节目数据传输，这就使节目数据传输过程中跨区域流量增加，而现有系统无法实现将P2P流媒体业务的流量限制在该客户端所在的区域内，即无法实现流量区域化，从而增加了骨干网络的负荷。However, the following problems exist in the prior art: the existing system for processing P2P streaming media services is mainly composed of content source servers, node index servers, channel portal servers and other service providing servers, management servers and edge servers. The system only has a set of service provider servers and management servers, and the edge servers are not divided into regions. Therefore, it is impossible to realize regional management of P2P streaming media services. For operators, such a system is difficult to control and manage ; and in the existing system, because the edge server is not divided by region, when the program data is transmitted between the client and the edge server, all the edge servers can be used as the provider of the program data in the P2P streaming media service, so that not only the same Program data can be transmitted between regional clients, and program data can also be transmitted between clients in different regions, which increases cross-regional traffic in the process of program data transmission, and the existing system cannot realize the traffic of P2P streaming services It is limited to the region where the client is located, that is, traffic regionalization cannot be realized, thereby increasing the load of the backbone network.

具体实施方式 Detailed ways
本发明P2P流媒体业务处理系统在保留现有的全网统一的管理类服务器的基础上，划分多个区域，每个区域内配置有例如内容源服务器、频道门户服务器等各种业务提供类服务器，并在每个区域设置一个综合服务器，用于管理其所在区域内的节点和各种业务提供类服务器，以及作为与其它区域内的服务器的统一接口；同时将边缘服务器也按照上述区域进行划分，并且根据实际需要可以在各区域内增加或减少边缘服务器。在划分的各区域内，通过边缘服务器与上述配置的各区域的业务提供类服务器，使客户端可以在其所在区域内实现P2P流媒体业务，从而使运营商可以对P2P流媒体业务分区域管理，符合运营商需要对P2P流媒体业务进行控制和管理的要求，并可以实现P2P流媒体业务的流量区域化，减少骨干网络的负荷。其中区域的划分可以按照现有网络结构以省为单位进行划分，各省的客户端均可以在本省内实现P2P流媒体业务，运营商可以以省为单位实现P2P流媒体业务的运营，有利于运营商进行网络部署和发展用户；同时由于各省的客户端均在本省内实现P2P流媒体业务，进行节目数据传输的流量均被限制在各个省内，最小化了各个省间的流量，从而实现了流量区域化，减少骨干网络的负荷。The P2P streaming media service processing system of the present invention divides a plurality of areas on the basis of retaining the existing unified management server of the whole network, and each area is configured with various service providing servers such as content source server, channel portal server, etc. , and set up an integrated server in each area to manage the nodes and various service-providing servers in its area, and serve as a unified interface with servers in other areas; at the same time, the edge servers are also divided according to the above areas , and edge servers can be increased or decreased in each region according to actual needs. In each divided area, through the edge server and the service provider server in each area configured above, the client can realize the P2P streaming media service in its area, so that the operator can manage the P2P streaming media service in different areas , which meets the requirements of operators to control and manage P2P streaming media services, and can realize the traffic regionalization of P2P streaming media services, reducing the load of the backbone network. Regions can be divided in units of provinces according to the existing network structure. Clients in each province can implement P2P streaming services in their own provinces, and operators can implement P2P streaming services in provinces, which is beneficial to operation network deployment and user development; at the same time, because the clients in each province implement P2P streaming media services in their own provinces, the traffic for program data transmission is limited to each province, minimizing the traffic between provinces, thus realizing Traffic regionalization reduces the load on the backbone network.
