    摘要： Systems and methods for publishing objects (e.g., pages and/or fragments) include assigning expiration times to different versions of objects and determining a plurality of objects which should be published atomically, that is, together in a single action. Then, the invention includes computing updated versions of the plurality of objects and atomically publishing the updated versions wherein the updated versions are not available until after expiration times corresponding to previously published versions of at least one of the plurality of objects (e.g., a cached object) have elapsed. Advantageously, clients attempting to access related cached objects over an information network such as the Internet will not be presented with versions of related objects that are inconsistent with one another.

    摘要： Methods for serving data include maintaining an incomplete version of an object at a server and at least one fragment at the server. In response to a request for the object from a client, the incomplete version of the object, an identifier for a fragment comprising a portion of the objects and a position for the fragment within the object are sent to the client. After receiving the incomplete version of the object, the identifier, and the position, the client requests the fragment from the server using the identifier. The object is constructed by including the fragment in the incomplete version of the object in a location specified by the position.

    摘要： In a computer system in which caching is utilized for improving performance, a method for determining whether an uncached object should be cached, and, if so, which objects, if any, should be removed from a cache to make room for the new uncached object. The method assigns a metric correlated with the desirability of caching an object, considering parameters such as access frequencies, object sizes, object lifetimes and times to calculate and/or to fetch the object. The metric weights more recent accesses more heavily than less recent accesses. The method can be used for improving the performance of an algorithm which utilizes priority queues and can additionally be applied when attempting to predict the expected frequency of an occurrence based upon past occurrences.

    摘要： Techniques are disclosed for load balancing in networks such as those networks handling telephony applications. By way of example, a method for directing requests associated with calls to servers in a system comprised of a network routing calls between a plurality of nodes wherein a node participates in a call as a caller or a receiver and wherein a load balancer sends requests associated with calls to a plurality of servers comprises the following steps. A request associated with a node belonging to a group including a plurality of nodes is received. A server is selected to receive the request. A subsequent request is received. A determination is made whether or not the subsequent request is associated with a node belonging to the group. The subsequent request is sent to the server based on determining that the subsequent request is associated with a node belonging to the group.

    摘要： A technique for delivering content in a client-server system based on a request received at a computing device from a client includes determining a current load on a next-level computing device of a hierarchy. When this current load is such that a response time for delivery of the request from the next-level computing device would increase above a given threshold, a client type associated with the request is checked and, when the client type indicates that the client is below a given priority level, content to be delivered to the client in response to the request is personalized at the receiving computing device. When the current load is such that the response time would not increase above a given threshold, the request is sent from the receiving computing device to the next-level computing device and the content to be delivered is personalized at the next-level computing device.

    摘要： Techniques are disclosed for load balancing in networks such as those networks handling telephony applications. By way of example, such techniques direct requests associated with calls to servers in a system comprised of a network routing calls between a plurality of callers and at least one receiver wherein a load balancer sends requests associated with calls to a plurality of servers as follows. A request associated with a call, a caller, or a receiver is received, depending on the particular load balancing technique. A server is selected to receive the request. A subsequent request is received. A determination is made whether or not the subsequent request is associated with the call, the caller, or the receiver, depending on the particular load balancing technique. The subsequent request is sent to the server based on determining that the subsequent request is associated with the call, the caller, or the receiver, again depending on the particular load balancing technique.
