Abstract
A bypass path is provided in the node for reducing the latency and power consumption associated with writing to and reading from the VC buffer, and is enabled when certain conditions are met. Bypass is enabled for a received packet when there is no other data that is ready to be sent from the VC buffer, which is the case when all VCs either have zero credits or an empty partition in the buffer. In this way, data arriving at the node is prevented from using the bypass path to take priority over data already held in the VC buffer and ready for transmission.
