We shall describe the PEP-II network which consists of a central host connected to an FDDI ring located around the PEP-II ring. FDDI-to-ethernet bridges connect the networked nodes to the FDDI ring. This network is separated from the rest of SLAC networks by the multihomed OpenVMS central host and two multihomed UNIX application gateways. The UNIX hosts act as EPICS control system OPIs providing data and displays to exterior networks. The network is addressed using a Private IP network address to further improve security. TCP/IP is required for EPICS and other applications to control the PEP-II equipment. This was a driving force to convert the SLC control system micro clusters to ethernet-based Multibus Single Board Computers along with TCP/IP software. This obsoletes the current SLAC-developed SLCNET communications system in areas accessible by the new PEP-II FDDI ring. We shall describe the details behind some of our design choices and the issues we faced while implementing this network. Show Partial Abstract
