Abstract

System and method for the unique naming of resources in networked environments including peer-to-peer network environments. Embodiments may be used to generate network resource identifiers that uniquely identify resources such as processes over time and across the networked environment. One embodiment may be implemented as a resource name generator that generates unique identifiers for resources in networked environments. One embodiment may generate unique network resource identifiers for processes from information including, but not limited to, a host address that uniquely identifies on the network the host machine of the resource for which the unique network resource identifier is being generated, a current time (e.g. obtained from the host machine or alternatively from an external source such as an atomic time server), and a process identifier of the process that uniquely identifies the process among current processes on the host machine.
