Abstract
In a multicomputer, concurrent computing system having a plurality of computing nodes, this is a method and apparatus for routing message packets between the nodes. The method comprises providing a routing circuit at each node and interconnecting the routing circuits to define communications paths interconnecting the nodes along which message packets can be routed; at each routing circuit, forming routes to other nodes as a sequence of direction changing and relative address indicators for each node between the starting node and each destination node; receiving a message packet to be transmitted to another node and an associated destination node designator therefor; retrieving the route to the destination node from a memory map; adding the route to the destination node to the beginning of the message packet as part of a header; transmitting the message packet to the routing circuit of the next adjacent node on the route to the destination node; and at each intermediate node, receiving the message packet; reading the header; directing the message packet to one of two outputs thereof as a function of routing directions in the header, updating the header to reflect passage through the routing circuit; and at the destination node, stripping remaining portions of the header from the message packet; storing the message packet; and, informing the node that the message packet has arrived.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
