Algorithmic Design of the Globe Wide-Area Location Service
As the Internet continues to grow exponentially, the problem of locating people, services, data, software, and machines is becoming more severe. To compound the problem, increasingly many users are no longer tied to a single, fixed access point, but instead are using mobile hardware such as telephones, notebook computers, and personal digital assistants. Applications must therefore take into ac...
متن کاملAlgorithmic Design of Lookup Operations in the Globe Location Service
A location service tracks and locates objects including those that are mobile. Such a service should provide an efficient means for updating and looking up an object’s address. However, current location services have limited scalability due to poor exploitation of locality and ineffective caching. This paper describes a worldwide location service that overcomes this limitation. An important asp...
متن کاملThe Architectural Design of Globe: A Wide-Area Distributed System
Developing large-scale wide-area applications requires an infrastructure that is presently lacking entirely. Currently, applications have to be built on top of raw communication services, such as TCP connections. All additional services, including those for naming, replication, migration, persistence, fault tolerance, and security, have to be implemented for each application anew. Not only is t...
متن کاملGlobe: a wide area distributed system
frastructure is still lacking. We propose Globe: a novel scalable infrastructure for a massive worldwide distributed system. Currently, designers build applications on top of a limited number of communication services. On the Internet, for example, this means that applications communicate mainly through transmissioncontrol protocol (TCP) connections, but otherwise must implement all additional ...
متن کاملSupporting Effective Caching in a Wide-Area Distributed Location Service
Globe is a wide-area distributed system that supports mobile objects. To track and locate objects, we use a worldwide distributed location service, implemented as a search tree. An object registers its current position by storing its address in a nearby leaf node of the tree. This knowledge propagates up to the top of the tree, so every object can be found from the root. Remote objects can cach...
