摘要： A base station controller (BSC) of a radio or wireless telecommunications network base station includes a director. A BSC includes multiple central processing units (CPUs), with each CPU running a call-processing application for one or more connections. The director is a logical entity that intercepts wireless call-setup signaling and assigns each corresponding connection to a CPU according to a centralized load-balancing algorithm. The centralized load-balancing algorithm distributes connections to less loaded CPUs to i) prevent individual CPUs from overloading, ii) utilize otherwise unused system resources, and iii) increase overall system performance. The director hosts cell components that manage code division multiple access (CDMA) downlink spreading codes for a base station, providing centralized allocation of spreading codes by the base station.

摘要： The amount of information associated with an electronic mail message that must be transmitted from an electronic mail server to a client electronic mail application at a user's computer or workstation is reduced using a cache-based compaction technique. This technique enable a requested electronic mail message to be encoded in the server using information relating to similar objects that were previously transferred by the server to the client and that remain available to the server. Differential encoding is performed in the server such that the server transmits to the client information indicative of the differences between the requested object and the reference (similar) objects available in the server cache. A corresponding decoding operation is performed in the client, using the encoded version and reference objects available in the client cache. A similar technique is employed for encoding electronic mail messages in the client that are to be transmitted to the server.

摘要： The amount of information that must be transmitted from an Internet server to a user's computer or workstation when the user requests an Internet object, for example, by clicking on a URL in a web browser application, is reduced using a cache-based compaction technique in which the requested object is encoded in the server using information relating to similar objects that were previously supplied to the user. Similar objects available in both a client side cache and a server side cache are selected by comparing the URL of the requested object to the URL's of stored objects. Differential encoding is performed in the server such that the server transmits to the client information indicative of the differences between the requested object and the reference (similar) objects available in the server cache. A corresponding decoding operation is performed in the client, using the encoded version and reference objects available in the client cache.

摘要： Techniques and systems for managing transmissions from a TCP source by regulating the flow of acknowledgement signals to the TCP source are described. An acknowledgement signal regulator monitors a data queue used to buffer data packets received from the TCP source and an acknowledgement signal queue used to store acknowledgement signals to be transmitted to the TCP source. An acknowledgement signal release manager determines the available space in the data queue and the expected number of data packets arriving at the data queue, and manages the release of acknowledgement signals from the acknowledgement signal queue to the TCP source so as to prevent an undesired overflow of the data queue resulting from the arrival of an excessive number of data packets from the TCP source.
