Techniques for performing an action, based on the present location of a client, to protect resources of the client from theft or unauthorized access. A server may intermittently receive, from a client, location information such as GPS information, triangulation information based on one or more Wi-Fi access points, and IP trace information. The server may determine the client's location by (a) determining, for an interval of time, whether GPS information, triangulation information, and IP trace information are available for the client, and (b) based on the available GPS information, triangulation information, and IP trace information, determining the present location of the client, e.g., by determining a weighted arithmetic mean or by using a sequence of types of location information ordered based on accuracy. In response to following a security policy, the server may perform an action, specified by the security policy, based on the present location of the client.

A system and method for a synchronous task scheduler. The synchronous task scheduler may be used with a CORBA Gateway between CORBA-based client manager applications and an enterprise manager. The CORBA Gateway may include components such as an Event Gateway which manages events from managed objects, and a Request Gateway which manages requests and responses of managed objects. The Event Gateway and the Request Gateway may be designed as multi-threaded systems. A thread pool may be used to increase efficiency and performance of the CORBA Gateway. To ensure ordered delivery of events or replies to the CORBA gateway clients in a multi-threaded environment using a thread pool, a synchronous task scheduler may be used. There may be a synchronous task scheduler associated with each client manager to preserve the chronology of messages sent to each. The synchronous task scheduler may maintain an internal message list, and deliver one message at a time from that internal list. The synchronous task scheduler may hold a reference to a thread pool and use that thread pool to deliver messages. When a message is scheduled, the synchronous task scheduler may check if any message is already being delivered. If no prior message is currently being delivered, an available thread may be assigned from the thread pool for delivery of the message and the scheduler may initiate delivery of the message. If a prior message is being delivered, it may enqueue the message in the message list. Then, when the prior message delivery is completed, the scheduler may dequeue the message, assign another thread from the thread pool, and initiate delivery of the message. This may continue until the message list is empty.

A method and apparatus for requesting bandwidth in a subscriber station is disclosed. The method dynamically changes the size of the bandwidth request based on the prediction of the number of packets needed to be transmitted. The average delay experienced by packets in a queue is measured, and this information is then used to change the coefficient of a prediction equation. When the experienced average delay is below the agreed upon QoS latency parameter or delay target, the method reduces the size of the bandwidth requests by making the prediction equation more conservative. On the other hand, when the experienced delay is above the agreed upon latency, the algorithm will make the prediction equation more aggressive, increasing the bandwidth requests and reducing the latency for future packets. By modifying the prediction equation based on the measured delay, the method is able to select the optimal point for achieving time delay requirements while preserving air-link resources.
