    "abstract": "The DZERO experiment located at Fermilab has recently started RunII with an\nupgraded detector. The RunII physics program requires the Data Acquisition to\nreadout the detector at a rate of 1 KHz. Events fragments, totaling 250 KB, are\nreadout from approximately 60 front end crates and sent to a particular farm\nnode for Level 3 Trigger processing. A scalable system, capable of complex\nevent routing, has been designed and implemented based on commodity components:\nVMIC 7750 Single Board Computers for readout, a Cisco 6509 switch for data\nflow, and close to 100 Linux-based PCs for high-level event filtering.",
