Abstract: The described embodiments distribute and synchronize objects in a network. More specifically, the described embodiments distribute copies of objects locally (i.e., store copies of objects in local address spaces). By storing a copy of a given object in a local address space, the object's methods may be executed locally, which can help to avoid excessive network traffic associated with remotely executing the object's methods. However, executing an object's methods locally can result in the state of the object (i.e., data associated with the object, etc.) becoming out of sync with other copies of the object in the network. To avoid issues associated with unsynchronized copies of the object in the network, the described embodiments use a policy that specifies conditions under which objects are to be synchronized.

Abstract translation: 所描述的实施例分发和同步网络中的对象。 更具体地，所描述的实施例在本地分配对象的副本（即，将对象的副本存储在本地地址空间中）。 通过将给定对象的副本存储在本地地址空间中，对象的方法可以在本地执行，这可以帮助避免与远程执行对象的方法相关联的过多的网络流量。 然而，本地执行对象的方法可导致对象的状态（即，与对象相关联的数据等）与网络中的对象的其他副本不同步。 为了避免与网络中对象的不同步副本相关的问题，所描述的实施例使用指定对象要被同步的条件的策略。
