电子商务的激增使一系列新的应用程序成为可能，这些应用程序允许通过互联网在全球范围内分散购买书籍、CD、旅游门票等商品。这些商品可以通过令牌在线表示，可以在服务器之间分发令牌，以增强此类应用的性能和可用性。有两种主要的方法来分发这样的令牌：复制和分区。令牌复制需要昂贵的分布式同步协议来提供数据一致性，并且在网络分区的情况下会受到高延迟和阻塞的影响。另一方面，令牌分区允许许多事务在本地执行，而不需要任何全局同步，这导致了低延迟和对网络分区的免疫力。
The proliferation of e-commerce has enabled a new set of applications that allow globally distributed purchasing of commodities such as books, CDs, travel tickets, etc., over the Internet. These commodities can be represented on line by tokens, which can be distributed among servers to enhance the performance and availability of such applications. There are two main approaches for distributing such tokens  replication and partitioning. Token replication requires expensive distributed synchronization protocols to provide data consistency, and is subject to both high latency and blocking in case of network partitions. On the other hand, token partitioning allows many transactions to execute locally without any global synchronization, which results in low latency and immunity against network partitions.
