Abstract
Techniques for maintaining consistent replicas of data are disclosed. By way of example, a method for managing copies of objects within caches, in a system including multiple caches, includes the following steps. Consistent copies of objects are maintained within the caches. A home cache for each object is maintained, wherein the home cache maintains information identifying other caches likely containing a copy of the object. In response to a request to update an object, the home cache for the object is contacted to identify other caches which might have copies of the object.
