Testing Ethernet Networks for the ATLAS Data Collection System
This paper reports recent work on Ethernet traffic generation and analysis. We use Gigabit Ethernet NICs running customized embedded software and custom-built 32-port Fast Ethernet boards based on FPGAs to study the behavior of large Ethernet networks. The traffic generation software is able to accommodate many traffic distributions with the ultimate goal of generating traffic that resembles th...
متن کاملTesting and Modeling Ethernet Switches and Networks for Use in ATLAS High - level Triggers
The ATLAS second level trigger will use a multi-layered LAN network to transfer 5 Gbyte/s detector data from ~1500 buffers to a few hundred processors. A model of the network has been constructed to evaluate its performance. A key component of the network model is a model of an individual switch, reproducing the behavior measured in real devices. A small number of measurable parameters are used...
متن کاملEthernet for the ATLAS second level trigger?
The use of Ethernet in implementing the ATLAS second level at the CERN Large Hadron Collider (LHC) is considered. Tests carried out on a large network testbed using 100 Mbps DS links and switches are used as a reference point. The evolution and present status of the IEEE 802.3 Ethernet standard is reviewed and technical problems in exploiting the technology at the LHC are explored.
متن کاملEvolution of Ethernet for Data Transport Networks
The Recent introduction of new revenue-generating services based on Ethernet has made more acute the need to improve Ethernet by adding features essential for efficient data transport. Various enhancements to the bridged Ethernet protocols in terms of scalability, OAM, restoration, QoS, and synchronization are being standardized that are making the native Ethernet protocols suitable for the agg...
