The receiving processor does not acknowledge any of the transfers until it receives the opcode which is always sent last. Upon receipt of the opcode, the receiving processor knows the instruction transfer is complete and sends the acknowledge signal immediately thereafter.

Oil well treatment

Data transfer method and apparatus

A method and apparatus are disclosed that allow a user to transfer relatively large files, such as full motion video, over a dedicated link with improved efficiency. Relatively cost effective high-speed TCP/IP links are available. However latency issues with TCP/IP prevents their use for transferring large files, especially full motion video for viewing in real time. The present method and apparatus establishes a multi-channel pipeline within the high-speed link from a source node to a target node. A desired file resident on a server of source node is first parsed into chunks of predetermined size appended with a sequence number and placed into circular buffer. The circular buffer is emptied into a next available channel in the multi-channel pipeline established in the high-speed link. The TCP/IP socket channels transfer chunks from the source node to the target node and acknowledge each chunk and then allow circular buffer to transfer the next available chunk. The target node stores the incoming chunks in circular buffer then transfers them in the file assembler into memory in dependence upon the sequence number. Once the file is reassembled it is transferred to server and made available to end user. Advantageously, a more cost effective link may be used for transfer of relatively large files. This technique may also be applied to access networks.

System and method for building packets

Memory requests and responses thereto include a tag that has a shift value indicating the misalignment between the first byte of required packet data and the first byte of a line of data in memory. A packet buffer controller receiving data with an associated tag uses the shift value to shift the received line of data accordingly. The first line of data for the packet data payload is shifted accordingly and written into the packet buffer. Subsequent lines of data require masking the previous line of data except for the last N bytes where N equals the shift value. The shifted line of data is written over the previous line so that the lower order bytes of the shifted received line of data are written. Then the shifted line of data is written into the next line of the packet buffer.
