Method and apparatus for communicating an optimized reply

Abstract: For optimized reply, when sending a reply (902) in a first embodiment a remote communication unit's controller (206) generates a delta between a preceding message and the reply message, and forms an optimized reply (904) using the delta and an identifier of the preceding message. On receiving the optimized reply, the communication server uses the data unit identifier to retrieve (910) the preceding message from a further server (e.g., the post office mailbox of the user associated with the remote unit), reconstructs (914) the full reply from the retrieved message and the delta, and forwards (916) the full reply to the addressee. When receiving a reply for the remote unit (918), an index is preferably maintained by both units of mail stored at the remote unit. From this index a preceding message forming part of the reply is identified (920). An optimized reply is then similarly formed (922) and sent to the remote unit.

Determining and displaying available services for a communication unit

Abstract: Information regarding available services from a RF communication system (101) is transmitted by the RF communication system on an RF communication resource(109). The information is received by at least one communication unit (108). The at least one communication unit (108) determines, from the information, the available services. The at least one communication unit (108) displays an indication of the available services on a display (206) for a user.

Botnet Research Survey

Abstract: Botnets are emerging threat with hundreds of millions of computers infected. A study shows that about 40% of all computers connected to the internet in the world are infected bots and controlled by attackers. This article is a survey of recent advances in botnet research. The survey classifies the botnet research into three areas: understanding botnets, detecting and tracking botnets, and defending against botnets. While botnets are widespread, the research and solutions for botnets are still in their infancy. The paper also summarizes the existing research and proposes future directions for botnet research.

Instruction fetch energy reduction using loop caches for embedded applications with small tight loops

Abstract: A fair amount of work has been done in recent years on reducing power consumption in caches by using a small instruction buffer placed between the execution pipe and a larger main cache. These techniques, however, often degrade the overall system performance. In this paper, we propose using a small instruction buffer, also called a loop cache, to save power. A loop cache has no address tag store. It consists of a direct-mapped data array and a loop cache controller. The loop cache controller knows precisely whether the next instruction request will hit in the loop cache, well ahead of time. As a result, there is no performance degradation.
