背景技术 Background technique
在流媒体领域， 流媒体服务器 （以下简称 VS ) 的并发能力一直是运营平 台中最关键的性能指标， 由于在较大并发情况下， VS随机读取节目数据的概 率大大增加， 导致磁盘读取效率大大降低， 往往远远无法满足网络 10的输出 能力， 因此磁盘 10在这里就成为了 VS并发性能的最大瓶颈，很多 VS软件商 都在 VS中增加了緩存机制， 但是由于在传统 32位服务器架构中， CPU的寻 址能力最大只有 232Bytes ( 4GB ), 也就说系统最大物理内存不能超过 4G, 并 且操作系统内核和其他服务也占用了不少内存， 剩下可以用来给 VS当作緩存 的物理内存就更有限了， 再加上视频文件尺寸较大（ 1M码率 90分钟的节目 文件尺寸约有 0.7GB ), VS不可能将数个视频文件全部緩存， 只能将其中的部 分信息进行緩存，比如视频文件的索引、会话预读緩存数据等。在这种策略下， VS虽然减少了一定的磁盘吞吐， 但整体性能并没有得到很大的提高， 由于节 目数据的庞大， 磁盘 10的瓶颈问题仍然没有摆脱。  In the field of streaming media, the concurrency capability of streaming media server (hereinafter referred to as VS) has always been the most critical performance indicator in the operating platform. Because of the large concurrency, the probability of VS randomly reading program data is greatly increased, resulting in disk reading. The efficiency is greatly reduced, and it is often far from meeting the output capability of the network 10. Therefore, the disk 10 becomes the biggest bottleneck of the VS concurrent performance here. Many VS software vendors have added a caching mechanism in the VS, but due to the traditional 32-bit server architecture. In the CPU, the maximum addressing capacity of the CPU is only 232Bytes (4GB), which means that the maximum physical memory of the system cannot exceed 4G, and the operating system kernel and other services also take up a lot of memory, and the rest can be used to cache the VS. Physical memory is more limited, plus the size of the video file is large (1M code rate 90 minutes of program file size is about 0.7GB), VS can not cache all the video files, only some of the information can be carried out Cache, such as indexing of video files, session read-ahead cache data, etc. Under this strategy, VS has reduced the disk throughput, but the overall performance has not been greatly improved. Due to the huge amount of program data, the bottleneck of disk 10 has not been undone.

具体实施方式 detailed description
为了使本发明的目的、技术方案及优点更加清楚明白， 以下结合附图及实 施例， 对本发明进行进一步详细说明。 应当理解， 此处所描述的具体实施例仅 仅用以解释本发明， 并不用于限定本发明。  The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
图 1示出了本发明实施例提供的节目存储方法的实现流程，其详细步骤如 下所述：  FIG. 1 is a flowchart showing an implementation process of a program storage method according to an embodiment of the present invention. The detailed steps are as follows:
在步骤 101中，根据热门级别对热门节目进行级别分类， 其中热门节目列 表记录每个热门节目的热门等级分类及热度。  In step 101, the popular programs are classified according to the popularity level, wherein the popular program list records the popularity ranking and popularity of each popular program.
在本发明实施例中，热门节目的等级为级别最高的热门节目及级别较低的 热门节目， 其中， 级别最高的热门节目为 T+类节目， 而级别较低的热门节目 为 T类节目。 In the embodiment of the present invention, the hot program has the highest level of popular programs and the lower level. Popular programs, among which the highest-ranking popular programs are T+ programs, while the lower-level popular programs are T-type programs.
在运营的开始， 系统可以根据节目自身的流行度来指定定义， 即指定某个 节目为某个级别的热门节目。在随后的热门节目的点播过程中，每个热门节目 的相关信息都会存储在热门节目列表中， 点播频率高的节目就是热门节目，在 该实施例中， 系统可以根据某个标准确定热门节目的分类级别， 例如规定超过 某个数值的热门节目就属于级别最高的热门节目， 而低于该数值的热门节目 为级别较低的热门节目，其中热门节目列表中有一字段就是标记该热门节目的 级别分类。  At the beginning of the operation, the system can specify a definition based on the popularity of the program itself, that is, designating a program as a certain level of popular programs. In the on-demand process of subsequent popular programs, relevant information of each popular program is stored in the popular program list, and the program with high frequency of on-demand is a popular program. In this embodiment, the system can determine the hot program according to a certain standard. The classification level, for example, a popular program that specifies a value exceeding a certain value belongs to the highest-ranking popular program, and a popular program below the value is a lower-level popular program, wherein a field in the popular program list is a level that marks the popular program. classification.
热度为每个热门节目被点播的次数，对于级别相同的热门节目， 通过热度 来决定热门节目在上述热门节目列表的排列顺序。  The popularity is the number of times each popular program is clicked. For popular programs of the same level, the order of the hot programs in the list of popular programs is determined by the heat.
在步骤 102中， 判断热门节目的级别类型， 若该热门节目为 T+类节目时， 则执行步骤 103; 若该热门节目为 T类节目时， 则执行步骤 104。  In step 102, the level type of the popular program is determined. If the hot program is a T+ program, step 103 is performed; if the hot program is a T program, step 104 is performed.
在本发明实施例中，该判断热门节目的级别类型的过程实际上就是判断在 热门节目列表中该热门节目的相应的级别分类字段的标记， 当该标记为 T+类 节目时就判定该热门节目为 T+类节目， T类节目也类似。  In the embodiment of the present invention, the process of determining the level type of the popular program is actually determining the mark of the corresponding level classification field of the popular program in the popular program list, and determining the popular program when the mark is a T+ program. For T+ programs, T programs are similar.
在步骤 103中， 若该热门节目为 T+类节目时， 则将该 T+类节目的内容全 部进行緩存， 供用户点播。  In step 103, if the popular program is a T+ program, the content of the T+ program is all cached for the user to order.
在步骤 104中，若该热门节目为 T类节目时，则将该热门节目的部分片段 进行緩存， 其中， 该部分片段为该热门节目的开始部分及热门片段部分进行緩 存。  In step 104, if the popular program is a T-type program, a partial segment of the popular program is cached, wherein the partial segment is cached for the beginning portion and the popular segment portion of the popular program.
在本发明实施例中，若该热门节目为 T类节目时，可以对该热门节目的内 容进行部分片段划分， 即该部分片段为节目的开始部分以及热门片段部分。在 该实施例中， 按照普通用户的观看习惯， 热门节目的开始部分是一定要看的， 因此该热门节目的开始部分要进行緩存，其中该热门节目的开始部分可以才艮据 实际需要进行设置， 例如可以设置为 10分钟； 然后就是在该 T类节目中的每 个精彩的片段进行划分， 然后对划分的该热门节目的热门片段进行緩存。  In the embodiment of the present invention, if the popular program is a T-type program, the content of the popular program may be partially segmented, that is, the partial segment is a beginning portion of the program and a hot segment portion. In this embodiment, according to the viewing habits of ordinary users, the beginning part of the popular program must be viewed, so the beginning part of the popular program is to be cached, wherein the beginning part of the popular program can be set according to actual needs. For example, it can be set to 10 minutes; then each of the wonderful segments in the T-type program is divided, and then the divided hot segments of the popular program are cached.
