摘要： Apparatuses and methods for managing jitter resulting from processing through a network interface pipeline are disclosed. In embodiments, a network traffic scheduler annotates packets to be transmitted over a bandwidth-limited network connection with time relationship information to ensure downstream bandwidth limitations are not violated. Following processing through a network interface pipeline, a jitter shaper inspects the annotated time relationship information and pipeline-imposed delays and, by imposing a variable delay, reestablishes bandwidth-complaint time relationships based upon the annotated time relationship information and configured tolerances.

摘要： A network processor includes first communication protocol ports that each support ‘M’ minimum size packet data path traffic on ‘N’ lanes at ‘S’ Gigabits per second (Gbps) and traffic with different communication protocol units on ‘n’ additional lanes at ‘s’ Gbps. The first communication protocol ports support access to an external coprocessor using parsing logic located in each of the first communication protocol ports. The parsing logic, during a parsing period, is configured to send a request to the external coprocessor at reception of a ‘M’ size packet and to receive a response from the external coprocessor. The parsing logic sends a request maximum ‘m’ size byte word to the external coprocessor on one of the additional lanes and receives a response maximum ‘m’ size byte word from the external coprocessor on the one of the additional lanes while complying with the equation N×S/M=

摘要： A network fabric may divide a physical connection into a plurality of VLANs as defined by IEEE 802.1Q. Moreover, many network fabrics use Priority Flow Control to identify and segregate network traffic based on different traffic classes or priorities. Current routing protocols define only eight traffic classes. In contrast, a network fabric may contain thousands of unique VLANs. When network congestion occurs, network devices (e.g., switches, bridges, routers, servers, etc.) can negotiate to pause the network traffic associated with one of the different traffic classes. Pausing the data packets associated with a single traffic class may also stop the data packets associated with thousands of VLANs. The embodiments disclosed herein permit a network fabric to individually pause VLANs rather than entire traffic classes.

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 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： Method and apparatus for providing a checksum in a network transmission. In one aspect of the invention, a checksum for a packet to be transmitted on a network is determined by retrieving packet information from a storage device, the packet information to be included in the packet to be transmitted. A blind checksum value is determined based on the retrieved packet information, and the blind checksum value is adjusted to a protocol checksum based on descriptor information describing the structure of the packet. The protocol checksum is inserted in the packet before the packet is transmitted.

摘要： Assigning work, such as data packets, from a plurality of sources, such as data queues in a network processing device, to a plurality of sinks, such as processor threads in the network processing device is provided. In a given processing period, sinks that are available to receive work are identified and sources qualified to send work to the available sinks are determined taking into account any assignment constraints. A single source is selected from an overlap of the qualified sources and sources having work available. This selection may be made using a hierarchical source scheduler for processing subsets of supported sources simultaneously in parallel. A sink to which work from the selected source may be assigned is selected from available sinks qualified to receive work from the selected source.

摘要： An assignment constraint matrix method and apparatus used in assigning work, such as data packets, from a plurality of sources, such as data queues in a network processing device, to a plurality of sinks, such as processor threads in the network processing device. The assignment constraint matrix is implemented as a plurality of qualifier matrixes adapted to operate simultaneously in parallel. Each of the plurality of qualifier matrixes is adapted to determine sources in a subset of supported sources that are qualified to provide work to a set of sinks based on assignment constraints. The determination of qualified sources may be based sink availability information that may be provided for a set of sinks on a single chip or distributed on multiple chips.
