这两个协议都使用端点标识符来识别服务器端中间件中的目标对象，且它们都使用方法标识符来确定待调用方法的签名。

Both protocols use endpoint identifiers to identify a target object within the server-side middleware and they both use method identifiers to determine the signature of the method to be invocated.

这些服务是用于客户端和服务器组件集成的中间件。

These services are middleware for integration between client and server components.

每个客户端都在本地连接，但被分配一个全局惟一的ID，以便在中间件的函数调用中客户端间可以相互引用。

Each client connects locally, but is allocated a globally unique id so that the clients may refer to each other in function calls to the middleware.
