摘要： A method, system and computer program product for detecting conditions of network instability. An attribute indicative of network instability, e.g., processor and/or co-processor utilization, packet arrival rates, packet peak rates, packet size distribution, packet clustering tendencies, buffer usage patterns, occurrence of peak utilization, out-of-buffer conditions, packet discard rates, may be monitored for a network device, e.g., router. The monitored attribute may be associated with a plurality of labels (variables) where a portion of those labels may be stored in a cache. A hit ratio for the cache storing labels associated with the monitored attribute may be tracked within a period of time based on the number of requested items, i.e., labels, that are currently stored in the cache. A condition of network instability may then be detected based on the hit ratio by determining if the absolute value of the acceleration of the hit ratio exceeds a threshold.

摘要： A method, system and computer program product for generating variable price billing whereby a customer may balance its data traffic in response to such billing. A subsystem in an edge gateway may extract the packet header from a copy of a received packet of data associated with a session between a customer and a server and generate a key based on the extracted packet header. The key may be used to index into a table that may store pointers to particular statistics records associated with particular sessions. Once the subsystem identifies the statistics record associated with the current session, the subsystem may execute a per packet statistics update for the statistics record associated with the session. A per packet statistics update may include one or more of the following: time stamping arrival of the packet, updating packet count, updating byte count, determining transfer rate, determining distance packet traveled.
摘要翻译：一种用于产生可变价格计费的方法，系统和计算机程序产品，由此客户可以响应于这种计费来平衡其数据流量。边缘网关中的子系统可以从接收到的与客户和服务器之间的会话相关联的数据分组的副本中提取分组报头，并且基于提取的分组报头来生成密钥。密钥可以用于索引到可以存储指向与特定会话相关联的特定统计记录的指针的表。一旦子系统识别与当前会话相关联的统计记录，则子系统可以执行与会话相关联的统计记录的每个分组统计更新。每个分组统计更新可以包括以下中的一个或多个：分组的时间戳到达，更新分组计数，更新字节计数，确定传送速率，确定行进的距离分组。

摘要： An interface connection is described for joining a host device, such as a Network Processor, to peripherals such as modems, printers, local area networks, Ethernets and Token-Ring interfaces. The connection is particularly useful for joining portable computers, such as laptops, to these peripherals. The connector utilizes a programmable Network Processor (NP) either in the host device or in an external fan-out box. This programmable Network Processor adapts the host device to a variety of peripheral devices utilizing different protocols and I/O speeds. The NP can use a Digital Signal Processor to provide programmable services to the physical layers. The host device may contain a high-speed communication interface with the NP contained in the external connection box.
