摘要： Techniques and articles of manufacture are provided comprising computer readable programs that, when executed on the computer, cause the computer to delete a leaf from a Patricia tree having a direct table and a plurality of PSCB's which decode portions of the pattern of a leaf in the tree without shutting down the functioning of the tree. A leaf having a pattern is identified as a leaf to be deleted. Using the pattern, the tree is walked to identify the location of the leaf to be deleted. The leaf to be deleted is identified and deleted, and any relevant PSCB modified, if necessary. The technique also is applicable to deleting a prefix of a prefix.

摘要： A line adapter for permitting the transfer of information between terminals and a bus connected to the central control unit CCU of a communications controller. The line adapter includes a microprocessor associated with a control memory and a scanner. A random access memory is split into zones, one zone being assigned to each line. During an initiating phase, the zones are personalized under the control of the microcode by sending initiating parameters (which are characteristics of the lines) to the memory, through an asynchronous path bus and external registers. Exchanges of temporarily-stored data between the CCU bus and the lines are carried out through cycle steal operations between the control memory and the random access memory.

摘要： A mechanism for offloading the management of send queues in a split socket stack environment, including efficient split socket queue flow control and TCP/IP retransmission support. An Upper Layer Protocol (ULP) creates send work queue entries (SWQEs) for writing to the send work queue (SWQ). The Internet Protocol Suite Offload Engine (IPSOE) is notified of a new entry to the SWQ and it subsequently reads this entry that contains pointers to the data that is to be transmitted. After the data is transmitted and acknowledgments are received, the IPSOE creates a completion queue entry (CQE) that is written into the completion queue (CQ). The flow control between the ULP and the IPSOE is credit based. The passing of CQ credits is the only explicit mechanism required to manage flow control of both the SWQ and the CQ between the ULP and the IPSOE.

摘要： A method and apparatus are used for finding the longest prefix match in a variable length prefix search when searching a direct table within a routing table structure of a network processor. The search through the routing table structure is expedited by hashing a first segment of an internet protocol address with a virtual private network number followed by concatenating the unhashed bits of the IP address to the result of the hash operation to form an input key. Patterns are compared a bit at a time until an exact match or the best match is found. The search is conducted in a search tree that provides that the matching results will be the best possible match.

摘要： An addressing model is provided where devices, including I/O devices, are addressed with internet protocol (IP) addresses, which are considered part of the virtual address space. A task, such as an application, may be assigned an effective address range, which corresponds to addresses in the virtual address space. The virtual address space is expanded to include Internet protocol addresses. Thus, the page frame tables are also modified to include entries for IP addresses and additional properties for devices and I/O. Thus, a processing element, such as an I/O adapter or even a printer, for example, may also be addressed using IP addresses without the need for library calls, device drivers, pinning memory, and so forth. This addressing model also provides full virtualization of resources across an IP interconnect, allowing a process to access an I/O device across a network.

摘要： A mechanism for offloading the management of send queues in a split socket stack environment, including efficient split socket queue flow control and TCP/IP retransmission support. As consumers initiate send operations, send work queue entries (SWQEs) are created by an Upper Layer Protocol (ULP) and written to the send work queue (SWQ). The Internet Protocol Suite Offload Engine (IPSOE) is notified of a new entry to the SWQ and it subsequently reads this entry that contains pointers to the data that is to be transmitted. After the data is transmitted and acknowledgments are received, the IPSOE creates a completion queue entry (CQE) that is written into the completion queue (CQ). After the CQE is written, the ULP subsequently processes the entry and removes it from the CQE, freeing up a space in both the SWQ and CQ. The number of entries available in the SWQ are monitored by the ULP so that it does not overwrite any valid entries. Likewise, the IPSOE monitors the number of entries available in the CQ, so as not overwrite the CQ. The flow control between the ULP and the IPSOE is credit based. The passing of CQ credits is the only explicit mechanism required to manage flow control of both the SWQ and the CQ between the ULP and the IPSOE.
摘要翻译： 一种卸载分组套接字堆栈环境中发送队列管理的机制，包括高效的分裂套接字队列流控制和TCP / IP重传支持。 当消费者发起发送操作时，发送工作队列条目（SWQE）由上层协议（ULP）创建并写入发送工作队列（SWQ）。 互联网协议套件卸载引擎（IPSOE）被通知一个新条目到SWQ，它随后读取这个条目，其中包含指向要发送的数据的指针。 在发送数据并接收到确认之后，IPSOE创建写入完成队列（CQ）的完成队列条目（CQE）。 在编写CQE后，ULP随后处理该条目并将其从CQE中删除，从而释放了SWQ和CQ两者的空间。 SWQ中可用的条目数由ULP进行监视，以使其不会覆盖任何有效的条目。 同样，IPSOE监视CQ中可用条目的数量，以免覆盖CQ。 ULP和IPSOE之间的流量控制是基于信用的。 CQ信用证的通过是在ULP和IPSOE之间管理SWQ和CQ两者流量控制所需的唯一明确的机制。

摘要： Mechanism for allowing data and packetized non coded information NCI such as packetized voice or images, to be exchanged between workstations connected to nodes of a communication network. The workstations arrange the bit stream to be sent into a format of regularly occurring time slots separated by flags. The data only containing time slots begin with a first flag (F2), the NCI only containing and NCI and data containing time slots begin with a second flag (F1) and inside these slots, flag F2 separates the NCI and data portions.The route between two workstations is established by a data session using the node resources. Once a route is established, the NCI portions of the bit stream are switched using high speed bus 26 and the data portions are routed using the normal data paths.
