Sending information using an in-progress transaction

A method for transmitting information from a second node to a first node, comprising the steps of:

• establishing a communication link between the first node and the second node;
• identifying a data transaction being transmitted from the second node via the data link to the first node;
• the data transaction including a header and a plurality of data pieces;
• the first node, based on data in the header, counting the data pieces to identify the end of the transaction;
• stalling the data transaction to send a packet on the communication link to the first node;
• the packet including the information;
• and
• the first node counting the packet as not part of the data transaction.

A system for transmitting information from a second node to a first node, comprising:

• a communication link between the first node and the second node;
• one or more data transactions transmitted on the communication link between the first node and the second node;
• a data stream of a data transaction being transmitted from the second node to the first node;
• and
• means for stalling the transaction to insert the information into the data stream, thereby transmitting the information from the second node via the data stream to the first node;
• wherein the information is not part of the data transaction when the data transaction starts from the second node to the first node.

A computer-readable medium embodying instructions for a computer to perform a method for transmitting information from a second node to a first node, the method comprising the steps of:

• establishing a communication link between the first node and the second node;
• allowing one or more data transactions transmitted on the communication link between the first node and the second node;
• identifying a data stream of a data transaction being transmitted from the second node to the first node;
• and
• stalling the transaction to insert the information into the data stream, thereby transmitting the information from the second node via the data stream to the first node;
• wherein the information is not part of the data transaction when the data transaction starts from the second node to the first node.
