ABSTRACT:
Employing a coherency controller having a primary path and at least one secondary path to at least one interconnection network is disclosed. A method of an embodiment of the invention is performed by the coherency controller of a node. The coherency controller determines whether transactions are being properly sent to other nodes of a plurality of nodes of which the node is a part via a primary path. In response to determining that the transactions are not being properly sent to the at least one interconnection network via the primary path, the coherency controller instead sends the transactions to the other nodes via a secondary path.
