[RPC](http://en.wikipedia.org/wiki/Remote_procedure_call) addresses above issues by abstracting the network communications as "clients access functions on servers": client sends a request to server, wait until server receives -> processes -> responds the request, then do actions according to the result.
Let's see how the issues are solved.

Common doubts on RPC:
- My data is binary and large, using protobuf is slow. First this is possibly a wrong feeling, you have to prove it with [profilers](docs/cn/cpu_profiler.md), second many protocols support carrying binary data along with protobuf requests and bypass the serialization.
- I'm sending streaming data, which can't be processed by RPC. Actually there're many protocols in RPC can handle streaming data, including [ProgressiveReader in http](docs/cn/http_client.md#持续下载), streams in h2, [streaming rpc](docs/cn/streaming_rpc.md).

- I don't need replies. With some inductions, we know that in your scene, requests can be dropped at any stage, because the client is always unaware of the situation. Are you really sure this is acceptable? Even if you don't need the reply, we recommend sending back small-size replies, which are unlikely performance bottlenecks and probably valuable clues when debugging complex bugs.
