摘要： A method, and apparatus for its use, for reducing the number of disk accesses needed to satisfy requests for reading data from and writing data to a hard disk. A non-volatile cache memory used to hold data blocks for which write requests have been made is purged of "dirty" blocks, not yet written to the disk, based on the proportion of dirty blocks in relation to an upper threshold and a lower threshold. A purge request flag is set when the proportion of dirty blocks goes above the upper threshold, but is not cleared until the proportion of dirty blocks goes below the lower threshold. So long as the purge request flag is set, dirty blocks are purged when the disk is not busy with read requests. Immediate purging is initiated when the write cache becomes totally full of dirty blocks. Purging of dirty blocks is also effected during disk read accesses, by "piggybacking" a writing operation with the reading operation, to write dirty blocks destined for the same track or cylinder in which the requested read data blocks are located.

摘要： A system for controlling the transmission of cells from a network node over multiple Virtual Circuits (VCs) is disclosed. The system performs traffic shaping, as required by connection based systems such as Asynchronous Transfer Mode (ATM), for each VC connected with a network node, so that the Quality of Service (Qos) parameters established when the connection was established are not exceeded. The system includes a process for scheduling the transmission of cells from the network node. The scheduling process periodically scans a table having entries corresponding to virtual circuits connected with the network node. During each scan of the table, the scheduler increments a sustainable rate accumulator field, a peak rate accumulator field, and a latency accumulator field of each table entry that corresponds with a virtual circuit that is open, and for which there is a cell ready to be transmitted. The scheduler further determines if the sustainable rate accumulator value is greater than or equal to a predetermined value and whether the peak rate accumulator value is greater than or equal to a predetermined value. If both conditions are true, then a cell may be transmitted on the virtual circuit corresponding with that table entry. The system further provides that transmissions are scheduled on virtual circuits having the greatest latency since previous transmissions.
摘要翻译：公开了一种用于通过多个虚拟电路（VC）来控制来自网络节点的小区的传输的系统。系统根据与网络节点连接的每个VC的连接系统（如异步传输模式（ATM））的要求进行流量整形，从而不会超过建立连接时建立的服务质量（Qos）参数。该系统包括用于调度来自网络节点的小区的传输的过程。调度过程周期性地扫描具有与与网络节点连接的虚拟电路相对应的条目的表。在表的每次扫描期间，调度器增加与打开的虚拟电路相对应的每个表条目的可持续速率累加器字段，峰值速率累加器字段和等待时间累加器字段，并且有一个单元准备好被传送。调度器还确定可持续速率累加器值是否大于或等于预定值，以及峰值速率累加器值是否大于或等于预定值。如果两个条件均为真，则可以在与该表条目对应的虚拟电路上发送一个单元。该系统进一步规定，在先前的传输之后，传输被安排在具有最大延迟的虚拟电路上。

摘要： A host system and an ATM network adapter using a chaser packet are presented. The adapter receives cells over a virtual connection on the network and generates, in response to the host system, a chaser packet which allows the host to detect that all data has been transferred form the adapter buffers to host memory. When all data has been transferred, the host may release the virtual connection without data loss. The host and adapter may also transmit data. In data transmission, the chaser packet is used to determine that all data has been transmitted out onto the network before the sending host releases the virtual connection. The chaser packet is also used for resynchronization of credits where the ATM network uses credit-based flow control. The adapter uses the chaser packet to drain the local queue so that the link between the adapter and a source system may be resynchronized.
摘要翻译：提出了使用追踪器分组的主机系统和ATM网络适配器。适配器通过网络上的虚拟连接接收信元，并响应于主机系统生成一个追踪器数据包，允许主机检测到所有数据已经从适配器缓冲区传送到主机存储器。当所有数据都被传输时，主机可以释放虚拟连接而不会丢失数据。主机和适配器也可以传输数据。在数据传输中，追踪器数据包用于在发送主机释放虚拟连接之前确定所有数据已经发送到网络上。追踪包也用于ATM网络使用基于信用流量控制的信用重新同步。适配器使用追踪器包来排除本地队列，以便可以重新同步适配器和源系统之间的链接。

摘要： Information needed by application programs from a secondary storage is cached in a cache memory which is organized in multiple levels, each level having multiple entries, the entries of each level receiving information of a predetermined category, each entry being accessible independently. Links are defined between entries of one level of the cache memory and entries at another level of the cache memory, the links corresponding to information relationships specified by a user of information stored in the secondary storage. In response to a request to a file system from an application for needed information, the needed information is fetched into the cache, and in connection with fetching the needed information, other information is prefetched from the system of files which is not immediately needed. Quotas are established on information which may be fetched from a secondary storage into the cache, the quotas being applicable to file contents within a file and to the number of files within a directory. Upon a request from an application program to open a file, an entry is created in a cache corresponding to the file, the entry including file header information. The file header information is retained in the cache so long as the file remains open, whether or not any file contents of the file remain in cache. The entries of three level of the cache respectively receive directory information, file header information, and file contents information.

摘要： A method and system are described to multicast with an adaptive dual state. The system receives multicast traffic over a membership tree including a first plurality of nodes connected in a first topology destined for a plurality of multicast members of a first multicast group. Next, the system determines a rate of multicast traffic that exceeds a predetermined threshold based on the receiving the multicast traffic. Next, the system generates a dissemination tree including a second plurality of nodes connected in a second topology to reduce a number of hops to communicate the multicast traffic to the plurality of multicast members of the first multicast group. Finally, the system forwards the multicast traffic to the plurality of multicast members of the first multicast group over the dissemination tree.
