An interconnect having a plurality of interconnect nodes arranged to provide at least one ring, a plurality of caching nodes for caching data coupled into the interconnect via an associated one of said interconnect nodes, and at least one coherency management node for implementing a coherency protocol to manage coherency of the data cached by each of said caching nodes. Each coherency management node being coupled into the interconnect via an associated one of said interconnect nodes. When each caching node produces a snoop response for said snoop request, the associated interconnect node is configured to output that snoop response in one of said at least one identified slots. Further, each interconnect node associated with a caching node has merging circuitry configured, when outputting the snoop response in an identified slot, to merge that snoop response with any current snoop response information held in that slot.
