Tight Coupling The Manageability Of The Industry Grid

Tightly Connected Industrial Grid is different from common Grids. All units ofTightly Connected Industrial Grid belong to a single organization, and are distributedgeographically. For one unit of such a grid, both of the unit itself and central unit havethe ability do system management on it. And the resource accesses between differenceunits need to be approved by the central unit.Moreover, Tightly Connected Industrial Grid emphasizes the reduction of TotalCost of Ownership (TCO).For Tightly Connected Industrial Grids, the expense ofmanagement is a key part of TCO, and this paper does research to cut the expenses ofmanagements, and then increase its manageability. The main contributions are:1,In this paper, the Tightly Connected Industrial Grid is analyzed, and it's keyrequirements for manageability is given;2,An architecture to support overall system monitoring and controlling isdesigned to reduce repeated labors of distributed administrators;3,The traditional Role Based Access Control (RBAC) module is expanded to beused with the resource access mechanism of Tightly Connected Industrial Grid, whichis defined in a formal model too.4,To handle accidents like unit joining, quitting, center disability and so on, aself-organizing protocol is designed, which can avoid the intervention ofadministrators, thus reduces TCO.5,Based on a cluster operating system Phoenix OS, which is developed byNCIC-ICT, we implemented one management platform for Tightly ConnectedIndustrial Grids, Phoenix Platform, and evaluate too.
