+This is a code release of Fastpass:
+  "a datacenter network framework that aims for high utilization with 
+   zero queueing. It provides low median and tail latencies for packets,
+   high data rates between machines, and flexible network resource 
+   allocation policies. The key idea in Fastpass is fine-grained control 
+   over packet transmission times and network paths.
+
+   A logically centralized arbiter controls and orchestrates all network 
+   transfers."
