If the client layer is making remote calls to the API layer, the client layer must use a protocol and transaction manager that supports the propagation of a transaction context (such as RMI-IIOP).
如果客户端层向api层发起远程调用，则客户端层必须使用支持传播事务上下文的协议和事务管理程序(比如说rmi - IIOP)。
The protocol reduces the normalized propagation delay of control channel.
本协议中控制通道的传播时延很小。
The Ice protocol provides a mechanism for implicit propagation of contextual information such as versioning, so we need not pollute all our object interfaces by adding an extra version parameter.
对于比如版本这样的上下文信息，Ice协议提供了一个隐式传播机制，我们不必为所有对象的接口都添加额外的版本参数。
