Abstract: A selective pre-caching system reduces the amount of content cached at cache proxies by limiting the cached content to that content that a particular cache proxy is responsible for caching. This can substantially reduce the content stored on each cache proxy and reduces the amount of resources consumed for pre-caching in preparation for a particular event. The cache proxy receives a list of content items that and an indication of the topology of the cache network. The cache proxy uses the received topology to determine the content items in the received list of content items that the cache proxy is responsible for caching. The cache proxy then retrieves the determined content items so that they are available in the cache before client requests are received.

Abstract: A wireless mouse for inputting commands to a host computer includes a casing, a control circuit, a wireless receiver, an electronic switch circuit and a resilient member. The control circuit includes a wireless module to transmit a wireless signal to the wireless receiver. The wireless receiver can be either received in the port of the casing or attached to a connector of the host computer. The electronic switch circuit includes a control terminal, a power input terminal connected to an external power source, and a power output terminal connected to the control circuit. The input and output power terminals are electrically connected or disconnected according to electrical potential at the control terminal. The resilient member is disposed on an inner side of the port. The resilient member is electrically connected with the control terminal by insertion of the wireless receiver in order to disconnect the input and output power terminals.

Abstract: A low latency streaming system provides a stateless protocol between a client and server with reduced latency. The server embeds incremental information in media fragments that eliminates the usage of a typical control channel. In addition, the server provides uniform media fragment responses to media fragment requests, thereby allowing existing Internet cache infrastructure to cache streaming media data. Each fragment has a distinguished Uniform Resource Locator (URL) that allows the fragment to be identified and cached by both Internet cache servers and the client's browser cache. The system reduces latency using various techniques, such as sending fragments that contain less than a full group of pictures (GOP), encoding media without dependencies on subsequent frames, and by allowing clients to request subsequent frames with only information about previous frames.

Abstract: A caching system segments content into multiple, individually cacheable chunks cached by a cache server that caches partial content and serves byte range requests with low latency and fewer duplicate requests to an origin server. The system receives a request from a client for a byte range of a content resource. The system determines the chunks overlapped by the specified byte range and sends a byte range request to the origin server for the overlapped chunks not already stored in a cache. The system stores the bytes of received responses as chunks in the cache and responds to the received request using the chunks stored in the cache. The system serves subsequent requests that overlap with previously requested ranges of bytes from the already retrieved chunks in the cache and makes requests to the origin server only for those chunks that a client has not previously requested.

Abstract: A load balancing system is described herein that proactively balances client requests among multiple destination servers using information about anticipated loads or events on each destination server to inform the load balancing decision. The system detects one or more upcoming events that will affect the performance and/or capacity for handling requests of a destination server. Upon detecting the event, the system informs the load balancer to drain connections around the time of the event. Next, the event occurs on the destination server, and the system detects when the event is complete. In response, the system informs the load balancer to restore connections to the destination server. In this way, the system is able to redirect clients to other available destination servers before the tasks occur. Thus, the load balancing system provides more efficient routing of client requests and improves responsiveness.

Abstract: A live caching system is described herein that reduces the burden on origin servers for serving live content. In response to receiving a first request that results in a cache miss, the system forwards the first request to the next tier while “holding” other requests for the same content. If the system receives a second request while the first request is pending, the system will recognize that a similar request is outstanding and hold the second request by not forwarding the request to the origin server. After the response to the first request arrives from the next tier, the system shares the response with other held requests. Thus, the live caching system allows a content provider to prepare for very large events by adding more cache hardware and building out a cache server network rather than by increasing the capacity of the origin server.
