Toward a Reliable Gigabit Network - An Upgrade of the SPring-8 Network

T.Fukui, M.Ishii, T.Masuda, T.Ohata and R.Tanaka

The SPring-8 controls network has maintained accelerator operations in high reliability and shown good performance in the past years. As loads on the network have increased due to faster data acquisition and addition of equipment data, networking hardware have been installed in the last few years. The upgraded network replaces the original FDDI backbone and switches with mixed FDDI/GigabitEthernet/shared memory network and Layer-3 switches. It is necessary to keep the double ring topology for the FDDI and introduce link aggregation technology for the Gigabit Ethernet to maintain full redundancy and bandwidth of the system. This paper will discuss the network performance of the Gigabit Ethernet including the latency and redundancy, and a measured bandwidth of the firewall systems with Gigabit Ethernet cards will be shown. We also discuss a future plan of the network including Quality-of-Service over the Gigabit Ethernet.
