In a peer-to-peer network system, a local node communicates with a remote node on which detailed information about content objects resides and optionally, the content objects reside. The local node uses caching, message request resizing and predictive message requesting to speed response time to user requests and internal control node requests.

A network caching system for streamed applications provides for the caching of streamed applications within a computer network that are accessible by client systems within the network. Clients request streamed application file pages from other client systems, proxy servers, and application servers as each streamed application file is stored in a cache and used. Streamed application file page requests are broadcast to other clients using a multicast packet. Proxy servers are provided in the network that store a select set of streamed application file pages and respond to client requests by sending a response packet containing the requested streamed application file page if the streamed application file page is stored on the proxy server. Streamed application servers store all of the streamed application file pages. Clients try to send requests to streamed application servers as a last resort. Clients can concurrently send requests to other clients, to a proxy server, and to a streamed application server. Clients measure the response time to the client's requests placing a positive weighting on the more responsive request path and sending subsequent requests to the more positively weighted request path first.

A method and apparatus for dynamically balancing the loading of data storage facilities is described. A listing is acquired of locations and loading of all segments of a requested data object including all copies of the segments of the requested data object. Those storage devices containing copies of each segment of the data object having a least loading is selected. If the loading of the storage devices is greater than the maximum loading for the storage devices, the segment is designated to be copied. The presence of all segments of the requested data object is determined. If there are missing segments of the requested data object, each of those missing segments is assigned a file identification and file location, such that those missing segments are assigned to data storage devices having the least loading. The missing segments are retrieved from a back-up storage device.

An approach is provided for supporting retrieval of a web page over a data network from a web site is disclosed. A downstream proxy communicating with a host executing a browser receives a request message from a browser to retrieve the web page. An upstream proxy parses the web page to determine an object embedded in the web page, wherein a promise list is generated specifying the embedded object that is to be pre-fetched according to a criterion. The promise list is transmitted to the downstream proxy, wherein the upstream proxy pre-fetches the embedded object from the web site. The upstream proxy determines whether to forward one of the pre-fetched embedded object to the downstream proxy based on a comparison of cookies associated with one of the pre-fetched objects supplied, respectively, by the browser and the web site. This approach as particular applicability in relatively high latency networks, such as a satellite communications system.

System and method for monitoring and controlling, defibrillation and pacing which allows a victim of a cardiac rhythm abnormality immediate access to a medical professional at a central station, who will remotely monitor, diagnose and treat the victim at one of a plurality of remote sites in accordance with the following steps:(1) providing a plurality of contact electrodes for a victim at a remote site for the receipt of ECG signals and for the application of electrical pulses to the victim;(2) transmitting the signals from the remote site to a central station and displaying them for review by the medical professional;(3) the medical professional selecting from a menu of defibrillation and pacing pulses, if the application thereof is appropriate;(4) transmitting the selection results to the remote site; and(5) receiving the selection results at the remote site and applying the selected pulses to the victim.
