Abstract
The present invention provides a method in a data processing system for efficiently sending a data packet from a source node to a destination node. The data processing system includes a multi-segment network having at least two segments, wherein the source node and the destination node are located within in different segments. Communication of a data packet from one segment to another segment is provided by an agent node. The present invention generates a data packet at the source node within a first segment on the multi-segment network. The data packet includes a source address, a destination address, and data. The data packet is then transmitted within the first segment and the source node retains ownership of the data packet. Thereafter, the data packet is received within the first segment at an agent node. The data packet is examined to determine the destination address and then transmit it to the destination node within a second segment in the multi-segment network. The data packet is thereafter received at the destination node within the second segment and an echo packet is automatically transmitted from the destination node to the source node to indicate a successful recepti…
