Simplified pipeline writes over a network

A method for transmitting data across a network, comprising:

• associating a sequence number with the data;
• associating an expected sequence number with the data, the expected sequence number related to data previously transmitted across the network;
• and
• transmitting the data, associated sequence number and expected sequence number across the network.

A method for receiving data sent across a network, comprising:

• receiving a first data packet, the first data packet comprising data, a sequence number, an expected sequence number, and a node-ID;
• determining whether a second data packet has already been received, wherein the second data packet has a sequence number corresponding to the expected sequence number of the first data packet;
• and
• responsive to a determination that the second data packet has already been received:
• storing the data of the first data packet.

A method for sending data over a network, the data transmitted by a first device coupled to a bus, the data written to a second device coupled to a second bus, the first bus and the second bus each coupled to the network, the method comprising:

• determining sequence information for the data, further comprising:
• associating a sequence number with the data;
• associating an expected sequence number with the data, the expected sequence number related to other data previously transmitted over the network;
• transmitting the data over the network;
• receiving response information indicating whether the data was accepted;
• and
• responsive to an indication that the data was not accepted:
• re-transmitting the data.

A method for writing first data received over a network to a device on a bus, the method comprising:

• determining sequence information associated with the first data, further comprising:
• determining a sequence number associated with the first data;
• determining an expected sequence number associated with the first data;
• determining whether the expected sequence number corresponds to a sequence number of second data previously received;
• responsive to the expected sequence number corresponding to the sequence number of the second data:
• writing the first data to the bus;
• sending an acknowledgement message;
• and
• responsive to the expected sequence number not corresponding to the sequence number of the second data, sending a retry request message.

A method for writing data to a device on a bus, comprising:

• receiving a first data packet over a network, the first data packet comprising a sequence number and a first data;
• receiving a second data packet over the network, the second data packet comprising an expected sequence number and a second data;
• responsive to the expected sequence number corresponding to the sequence number:
• storing the second data.

A system for transferring a data packet across a network, the data packet comprising data, a sequence number and an expected sequence number, the system comprising:

• a sending module, for sending the data packet across the network, and further comprising:
• a bus communication module, for receiving the data from a bus;
• a sequencing module, for assigning the sequence number and the expected sequence number to the data packet;
• a data transmission module, for transferring the data packet a receiving module across the network;
• the receiving module, coupled to the network, for receiving the data packet, and further comprising:
• a sequence table module, for determining whether the data packet has been received in a correct order;
• a data buffer for storing the data;
• and
• an acknowledgement module, for sending an acknowledgement to the sending module.
