利用Vlan技术在千兆以太网上升级Spring-8 Beamline网络
Upgrade of Spring-8 Beamline Network with Vlan Technology Over Gigabit Ethernet
摘要：
SPring-8的束线网络系统由三个LAN组成：用于束线组件控制的BL-LAN、用于束线实验用户的BL-USER-LAN和用于信息服务的OA-LAN。这些局域网通过防火墙系统互连。由于网络流量和光束线数量的增加，我们将BL-USER-LAN的主干从快速以太网升级为千兆以太网。在此基础上，为了建立单条波束线的独立性，提高每条波束线的灵活性，我们还将IEEE802.1Q虚拟局域网（VLAN）技术引入到BL-USER-LAN中。我们在这里讨论了一个未来的计划，建立防火墙系统与硬件负载均衡器。
英文摘要：
The beamline network system at SPring-8 consists of three LANs; a BL-LAN for beamline component control, a BL-USER-LAN for beamline experimental users and an OA-LAN for the information services. These LANs are interconnected by a firewall system. Since the network traffic and the number of beamlines have increased, we upgraded the backbone of BL-USER-LAN from Fast Ethernet to Gigabit Ethernet. And then, to establish the independency of a beamline and to raise flexibility of every beamline, we also introduced the IEEE802.1Q Virtual LAN (VLAN) technology into the BL-USER-LAN. We discuss here a future plan to build the firewall system with hardware load balancers.
