GETB, a gigabit Ethernet application platform: its use in the ATLAS TDAQ network
M. D. Ciobotaru, Stefan Nicolae Stancu, M. J. LeVine, B. Martin · 2005
The ATLAS trigger and data acquisition system (TDAQ) employs a large high-speed Ethernet-based network, comprising several hundred nodes. Ethernet switches handle all the data transfers, their performance being essential for the success of the experiment. We designed and implemented a system, the GETB (gigabit Ethernet testbed), which can be used to assess the performance of network devices. This article introduces the architecture and the implementation of the GETB platform, as well as its applications. These include the GETB network tester and the ATLAS read-out buffer emulator. The features of the system are described and sample results are presented
