摘要： In a first aspect, a first method of transmitting a data packet is provided. The first method includes the steps of (1) for each connection from which a data packet may be transmitted, storing header data corresponding to the connection; (2) employing a user application to form header and payload data of a packet, wherein the user application is associated with a connection from which the packet is to be transmitted; and (3) while transmitting the packet, comparing one or more portions of the packet header data with the header data corresponding to the connection with which the user application is associated. Numerous other aspects are provided.

摘要： A method and apparatus tracks packets and reliably transmits data over a computer transmission system with a reduced amount of memory needed in the transmission interface. The invention eliminates the need to keep all the packets of data queued until the acknowledge message for that data has arrived. Instead, it keeps track of how many packets have been sent and which packets correspond to the end of a message, marking them off when acknowledge messages are received. If packets are lost, the invention determines which packet were lost, backs up to the lost packet, re-fetches the data and resends it. Embodiments of the present invention eliminate the need to queue packets, reducing silicon size and allowing the available bandwidth of the output bus to be more fully utilized.
摘要翻译：一种方法和装置跟踪分组并通过计算机传输系统可靠地传输数据，传输接口中所需的存储器数量减少。本发明消除了在数据的确认消息到达之前排队所有数据包的需要。相反，它跟踪已经发送了多少个数据包，哪些数据包对应于消息的结尾，在接收到确认消息时将它们标记出来。如果分组丢失，则本发明确定哪个分组丢失，备份到丢失的分组，重新获取数据并重新发送。本发明的实施例消除了对分组进行排队的需要，减小了硅尺寸并且允许更充分地利用输出总线的可用带宽。

摘要： An Ethernet adapter is disclosed. The Ethernet adapter comprises a plurality of layers for allowing the adapter to receive and transmit packets from and to a processor. The plurality of layers include a demultiplexing mechanism to allow for partitioning of the processor. A Host Ethernet Adapter (HEA) is an integrated Ethernet adapter providing a new approach to Ethernet and TCP acceleration. A set of TCP/IP acceleration features have been introduced in a toolkit approach: Servers TCP/IP stacks use these accelerators when and as required. The interface between the server and the network interface controller has been streamlined by bypassing the PCI bus. The HEA supports network virtualization. The HEA can be shared by multiple OSs providing the essential isolation and protection without affecting its performance.

摘要： A method and system for performing a lookup for a packet in a computer network are disclosed. The packet includes a header. The method and system include providing a parser, providing a lookup engine coupled with the parser, and providing a processor coupled with the lookup engine. The parser is for parsing the packet for the header prior to receipt of the packet being completed. The lookup engine performs a lookup for the header and returns a resultant. In one aspect, the lookup includes performing a local lookup of a cache that includes resultants of previous lookups. The processor processes the resultant.

摘要： Concurrent read access and exclusive write access are provided in a shared memory architecture to permit one or more devices in the shared memory architecture to maintain read access to a block of memory such as a cache line while one device has exclusive permission to modify that block of memory. By doing so, a device that has permission to modify may make updates to its copy of the block of memory without invalidating other copies of the block of memory, and potentially enabling other devices to continue to read data from their respective copies of the block of memory without having to retrieve the updated copy of the block of memory.

摘要： A method, apparatus, system, and signal-bearing medium that in various embodiments determine whether to execute a command in a queue or whether to wait until another command or commands completed. The determination is based on a combination of an in-use vector and a scorecard vector. The in-use vector indicates which slots in various queues contain commands. The scorecard vector indicates the dependencies between various queues. In this way, the scorecard vector, and the thus the queue dependencies can be set and modified after the logic that processes the commands has been designed.

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： A method for coalescing acknowledge packets within a server is disclosed. A Read Request queue having multiple queue pair entries is provided. Each of the queue pair entries includes a packet sequence number (PSN) field and an indicator field. In response to a receipt of a Write Request packet, an indicator field of a queue pair entry is set to indicate that an Ack packet has been queued within the queue pair entry, and a PSN of the Write Request packet is written into a PSN field of the queue pair entry. In addition, a Queue Write Pointer is maintained to point to the queue pair entry. In response to a receipt of a Read Request packet, the indicator field of the queue pair entry is set to indicate that a Read Request packet has been queued within the queue pair entry, and a PSN of the Read Request packet is written into the PSN field of the queue pair entry. Also, the Queue Write Pointer is advanced to point to a queue pair entry that is subsequent to the queue pair entry.
