A communications architecture utilizes modules arranged in a daisy-chain, each module supporting multiple input and output ports. Point-to-point links are arranged so that a first output link of each of multiple modules connects to the next module in the chain, and a second output link connects to a module after it, and inputs arranged similarly, so that any single module can be by-passed in the event of malfunction. Multiple chains may be cross-linked and/or serviced by hubs or chains of hubs. Preferably, the redundant links are used in a non-degraded operating mode to provide higher bandwidth and/or reduced latency of communication. The exemplary embodiment is a memory subsystem in which the modules are buffered memory chips.
