Abstract: 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.

Abstract translation: 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。

Abstract: 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.

Abstract: 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.

Abstract translation: 用于计算盲校验和的系统和方法包括具有用于接收分组的系统的主机以太网适配器（HEA）。 系统确定数据包是否处于Internet协议版本四（IPv4）中。 如果分组不在IPv4中，则系统计算分组的校验和。 如果分组在IPv4中，则系统确定分组是否在传输控制协议（TCP）或用户数据报协议（UDP）中。 如果分组不在TCP或UDP中，则系统将伪报头附加到分组，并基于伪报头和IPv4标准计算分组的校验和。
