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.

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： For enhanced efficiency in setting up routes, and for enhanced throughput in an ATM network, invocation of objects can be parallelized. Also, throughput of a connection manager can be increased, and the latency of call set-up decreased by caching of network states such as recently used routes, output or input VCI/VPIs, bandwidth and buffer resources and existing connection states. And systems throughput can be increased by aggregating multiple request messages into a single invocation instead of making multiple invocations.
摘要翻译：为了提高路由设置的效率，并提高ATM网络的吞吐量，可以并行调用对象。此外，可以增加连接管理器的吞吐量，并且通过缓存网络状态（例如最近使用的路由，输出或输入VCI / VPI，带宽和缓冲器资源以及现有连接状态）来减少呼叫建立的延迟。通过将多个请求消息聚合成一个单独的调用，而不是进行多次调用，可以提高系统吞吐量。

摘要： The amount of TCP/IP packets which can be sent from an Internet network to a wireless network is maximized by modifying a receive window value of an acknowledgment (ACK) before the ACK is sent on to a source of data packets within the Internet network. The receive window value is modified to take into consideration delay and rate variations which occur in the wireless network.

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.
