# 串流

與 SCTP、SSH 和 HTTP/2 相似，QUIC 在物理連接內具有獨立的邏輯流。 許多並行流可以透過單個連接同時傳輸資料，而不會影響其他流。

連接兩個端點之間的協商設置是類似於 TCP 連接的工作方式。 QUIC 連接建立到 UDP 端口和 IP 地址，但是一旦建立，該連接就由其 "連接ID"（ connection ID ）關聯。

通過已建立的連接，任何一方都可以創建流並將資料發送到另一端。 單一串流的傳輸是可靠、有序的，但不同的串流間可能會有無序傳送。

QUIC 可對連接和串流分別進行流量控制（ flow control ）。

進一步細節請參考 [連接](/zh-tw/quic/quic-connections.md) 和 [QUIC串流](/zh-tw/quic/quic-streams.md)。

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://http3-explained.haxx.se/zh-tw/the-protocol/feature-streams.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
