Title: John J. Chiang and Scalable Network Caching

Introduction

John J. Chiang is an inventor associated with San Francisco, California. His patent work focuses on scalable distributed caching systems that help networks locate, share, and maintain copies of data objects. He is credited with 2 patents.

Latest Patents

“Scalable Network Object Caching” describes a distributed system that locates caches holding a requested data object. It polls those caches, retrieves a copy from the first one to confirm availability, and stores the copy at the cache handling the user’s request. The system then updates its directory list and uses distributed deletion and time-to-live parameters to help keep cached copies coherent.

“Scalable Distributed Caching System and Method” describes a similar approach to locating and retrieving data across network caches. A directory cache maintains a list of locations that may hold the requested object. After polling those locations, the system obtains a copy from a responding cache, serves it to the user, and adds the receiving cache to the directory list. Distributed deletion and time-to-live parameters help manage outdated copies.

Career Highlights

Chiang’s listed inventions address the challenges of distributing data across networked caches. Their methods combine directory-based lookup, cache polling, replication, and mechanisms for managing stale copies. The supplied information associates him with AT&T Corp.
