We present a novel prioritization technique to reduce latencies in Network-on-chips. For individual routers, we adaptively allocate default paths assuming that subsequent packages are part of a data stream and, thus, routing decisions are identical. Since proactive routing to an output port is performed, the conventional router pipeline is partly bypassed. The method is deterministic, non-speculative with local and autonomous decisions, retains the standard network load, and does not penalize non-prioritized links. Virtual point-to-point connections emerge, which span multiple hops and accelerate interleaved streams. We achieve an average package latency reduction of 4.8% to 12.2% in simulations for PARSEC benchmarks.
