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： A system and method for computing a blind checksum includes a host Ethernet adapter (HEA) with a system for receiving a packet. The system determines whether or not the packet is in Internet protocol version four (IPv4). If the packet is not in IPv4, the system computes the checksum of the packet. If the packet is in IPv4, the system determines whether the packet is in transmission control protocol (TCP) or user datagram protocol (UDP). If the packet is not in either of TCP or UDP the system attaches a pseudo-header to the packet and computes the checksum of the packet based on the pseudo-header and the IPv4 standard.

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 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： 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 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.
