Seamless management of resource constrained wireless devices along with enterprise hosts is complex because of the multitude of management protocols and architectures. An atomic and coordinated management action that spans the scale of the enterprise is needed. In this paper we present the architecture and our experiences in building a Universal Manager that manages all mobile and non-mobile devices in the enterprise. We came up with a multi-protocol gateway that blends intermittently connected mobile devices seamlessly with enterprise hosts. Our implementation of SyncML based mobile devices integrated with SNMP based enterprise manager is deployed in the enterprise and performance results are presented.
