Abstract
The goal of the LHCb readout upgrade is to accelerate the DAQ to 40 MHz. Such a DAQ system will certainly employ 10 Gigabit or similar technologies and might also need new networking protocols such as a customized, light-weight TCP or more specialized protocols. A test module is being implemented to be integrated in the existing LHCb infrastructure. It is a multiple 10-Gigabit traffic generator, driven by a Stratix IV FPGA, and flexible enough to generate LHCb's raw data packets. Traffic data are either internally generated or read from external storage via the network. We have implemented a light-weight industry standard protocol ATA over Ethernet (AoE) and we present an outlook of using a file-system on these network-exported disk-drivers.
