Abstract: A method for cache sharing among branch proxy servers. A branch proxy sever receives a request for accessing a resource at a data center. The branch proxy server creates a cache entry in its cache to store the requested resource if the branch proxy server does not store the requested resource. Upon creating the cache entry, the branch proxy server sends the cache entry to a master proxy server at the data center to transfer ownership of the cache entry if the master proxy server did not store the resource in its cache. When the resource becomes invalid or expired, the master proxy server informs the appropriate branch proxy servers storing the resource to purge the cache entry containing this resource. In this manner, the master proxy server ensures that the cached resource is synchronized across the branch proxy servers storing this resource.

Abstract: An improved solution for managing messages through a request response protocol network utilizing a path-based adaptive prioritization and latency management is provided. A weight for a message is determined at a message management computing device based upon a number of hops and a latency of networks passed through by the message. A hop latency target for a current hop segment is evaluated relative to an overall latency target and the determined weight for the message. A priority of the message is adjusted in response to determining that the overall latency target, relative to the weight for the message and the hop latency target for the current hop segment, exceeds a configured allowable hop latency deviation for the current hop segment.

Abstract: An improved solution for managing messages through a request response protocol network utilizing a path-based adaptive prioritization and latency management is provided. In an embodiment of the invention, a method of managing a message being conveyed through a request response protocol network via a path includes: receiving the message; determining for the message at least one of: an incoming portion of the path or an outgoing portion of the path; and adjusting a priority of the message based on a latency target for the determined portion of the path.

Abstract: A method, system and computer program product for cache sharing among branch proxy servers. A branch proxy sever receives a request for accessing a resource at a data center.

Abstract: The present invention discloses a method and a system for using presence proxies to group presence notifications. In the invention, a presence server can accept, manage, and distribute presence information. Multiple watchers can subscribe to the presence information managed by the presence server. A presence proxy can receive or intercept subscription requests from the watchers, can group these subscription requests, can establish a single subscription between the presence proxy and the presence server for each group of subscription request, can receive notifications form the presence server associated with the single subscription, and can convey received notifications to each of the watchers in a group associated with the single subscription responsive to receiving a corresponding notification from the presence server.

Abstract: The present invention discloses a solution that uses presence proxies to handle local presence information while using a presence server to handle extra-local presence information. In the invention, a computing system can include multiple presence user agents (PUAs), multiple watchers, multiple presence proxies, and a presence server. The PUAs can be are grouped into two or more sub-networks. The watchers can also be grouped by sub-network. The PUAs and the watchers can each be associated with a presentity. A presence proxy can be associated with each of the sub-networks. Exclusively local presence services for each sub-network ears be handled by the associated presence proxy. The presence proxy can route presence information for other presence services (those not exclusively local) to and from the presence server.
