摘要： The present invention provides a method of and a system for providing buffer management mechanism in an on-Demand environment to keep the popular content sections in server memory so as to reduce the repeatable disk I/O and improve the server performance. The method comprises: setting the state of a buffer to be ACTIVE when a file section stored in the buffer is requested by any users; setting the state of the buffer to be INACTIVE when users no longer request the file section stored in the buffer, the buffer in INACTIVE state having a lifetime; changing the state of the buffer from INACTIVE to FREE when the lifetime decreases to zero. The system comprises at least one detector for detecting the number of the users requesting a file section stored in the buffer and providing the detection results for a processor, one processor for determining the state of the buffer according to the detection results and providing instructions for at least one state setting unit, and at least one state setting unit for setting the state of the buffer based on instructions from the processor.
摘要翻译：本发明提供了一种用于在按需环境中提供缓冲器管理机制的方法和系统，以将流行内容部分保留在服务器存储器中，以便减少可重复的磁盘I / O并提高服务器性能。该方法包括：当任何用户请求存储在缓冲器中的文件段时，将缓冲器的状态设置为ACTIVE; 当用户不再请求存储在缓冲区中的文件段时，将缓冲区的状态设置为INACTIVE，在INACTIVE状态的缓冲区具有生存期; 当生命周期减少到零时，将缓冲区的状态从INACTIVE更改为FREE。该系统包括至少一个检测器，用于检测请求存储在缓冲器中的文件部分的用户的数量，并为处理器提供检测结果;一个处理器，用于根据检测结果确定缓冲器的状态，至少一个状态设置单元，以及至少一个状态设置单元，用于基于来自处理器的指令来设置缓冲器的状态。

摘要： A user equipment node, upon determining that the data loss in a requested file is above, or likely to be above a threshold value, transmits a delivery missing report to a server node indicating that the data loss in the requested file is above the threshold value. The delivery missing report is used by the server node for determining whether or not a multicast file repair procedure should be enabled, based on the number of delivery missing reports it has received from other user equipment nodes. This enables a point-to-multipoint file repair procedure to be enabled sooner, and prevent a flood of point-to-point file repairs.
摘要翻译：用户设备节点在确定所请求的文件中的数据丢失高于或可能高于阈值时将传送缺失报告发送到服务器节点，指示所请求的文件中的数据丢失高于阈值。根据其从其他用户设备节点接收的传送缺失报告的数量，服务器节点使用传送缺失报告来确定是否应启用多播文件修复过程。这使得能够更快地启用点对多点文件修复过程，并防止大量的点对点文件修复。

摘要： A method and apparatus are provided for delivering multicast media in a network in which at least some nodes do not support delivery of multicast packets. A RTSP SETUP request is sent to a streaming server to send multicast packets, encapsulated within unicast wrappers, to a gateway node in the network. The RTSP SETUP request includes details both of the multicast destination address, and of the unicast destination address of the gateway node, requiring an extension to the RTSP protocol as currently defined and enabling the media server to send multicast packets in a unicast tunnel dynamically.
