摘要： A system, apparatus and method for transparently authenticating continuous data streams. A continuous data stream is divided into data blocks. Block authentication code(s) are determined using the data in the data blocks, a hash function and a key. The block authentication code(s) are embedded into the data block(s) by adjusting the timing between the packets in the data block(s). Timing delays may be used to separate the blocks. The continuous data stream may be received and authenticated by comparing an extracted block authentication code with a new calculated content-based block authentication code.

摘要： A worm containment system comprising a host computing machine, a virtual machine running under the control of a virtual machine monitor, a worm detector, a diverter and a buffer. The host computing machine has a host operating system and host application(s). The virtual machine has a clone of the host operating system and a clone of the host application(s). The worm detector is configured to monitor the virtual machine traffic for signs of worm propagation. The splitter is configured to duplicate packets intended for the host computing machine into diverted packets and buffered packets. The diverter is configured to route the diverted packets to the virtual machine. The buffer is configured to store the buffered packets and then forward the buffered packets to the host operating system on indication from the worm detector that no worm propagation behavior was detected.

摘要： Methods and systems for supplying media over communication networks are described. In one embodiment, a media supplier determines whether a media object hosted on a web server will be supplied to a client by streaming or not by streaming. Preferably, if the determination is to stream, the media supplier streams the media object to the client. Otherwise, the media supplier preferably allows the host web server to supply the media object to the client. In some cases, the same media supplier may be capable of supplying clients with media objects hosted on any of at least two web servers.

摘要： A method and system for streaming media objects. A streaming system includes a group of end nodes and at least one core node connected via an overlay network. The end nodes cache segments of media objects and stream the media objects to a client segment by segment. Each end node stores segment indices for locating segments cached on end nodes or a core node in the system. The core node is a dedicated proxy which fetches media objects from a remote media server and streams the media objects to a client when the media objects are unavailable from the end nodes.

摘要： Methods and systems for prioritizing content are described. A request for a first content object is received at a caching proxy. A search of an access log of the proxy cache for a portion of the first content object is then performed. The size of the portion of the first content object on the proxy cache is calculated and the normally utilized size of the segment of the first content object is derived. A comparison is then made between the size of the portion of the first content object on the proxy cache and the normally utilized size of the first content object requested.

摘要： A server-proxy-client network delivers web content objects from servers to clients from cache content at a proxy server in between. Multiple, moving-window buffers are used to service content requests of the server by various independent clients. A first request for content is delivered by the server through the proxy to the requesting client. The content is simultaneously duplicated to a first circulating buffer. Once the buffer fills, the earlier parts are automatically deleted. The buffer therefore holds a most-recently delivered window of content. If a second request for the same content comes in, a check is made to see if the start of the content is still in the first buffer. If it is, the content is delivered from the first buffer. Otherwise, a second buffer is opened and both buffers are used to deliver what they can simultaneously. Such process can open up third and fourth buffers depending on the size of the content, the size of the buffers, and the respective timing of requests.
摘要翻译：服务器 - 代理 - 客户端网络从服务器到客户端之间的代理服务器的缓存内容传送Web内容对象。多个移动窗口缓冲区用于为各种独立客户端的服务器的内容请求提供服务。内容的第一个请求由服务器通过代理传递给请求客户端。内容同时复制到第一循环缓冲器。一旦缓冲区填满，早期的部件将被自动删除。因此，缓冲区拥有最近发布的内容窗口。如果对相同内容的第二个请求进入，则检查内容的开始是否仍在第一个缓冲区中。如果是，内容是从第一个缓冲区传递的。否则，打开第二个缓冲区，并使用两个缓冲区来同时提供它们。该过程可以根据内容的大小，缓冲器的大小以及各个请求的定时来打开第三和第四缓冲器。

摘要： A peer-to-peer communication system in which a peer communicating with a tracker node on a local torrent can locate and download files that are not currently available from other peers communicating on the local torrent. To enable this, the tracker node maintains collaboration information for a list of files. The collaboration information includes, for each file, a list of locations at which a full copy of the file may be located. The list of locations may include active peers, dormant peers and remote tracker nodes. The collaboration information may be obtained from each peer when it joins a local torrent. Upon joining the torrent, the peer may provide the local tracker node with a list of files that it is willing to serve.
