how blink communicates with network?

[sangitac...@gmail.com]

Hi Guys,

I want to know whether blink has its own networking stack or it uses chrome networking stack - "http://www.chromium.org/developers/design-documents/network-stack"
I have confused because I have seen page - "http://www.chromium.org/blink/blink-network-stack".
I am testing with Android- Kitkat, chrome networking stack is not hitting with chrome browser. Can anybody help me for this?

Regards,
Sangeeta

Blink does not have a network stack, it relies on the network stack of Chromium.

I am not sure about the network stack architecture of Chromium for Android, though. I think Chrome for Android has its own still, but the Android KitKat WebView version is different in this regard (for example, uses the system OpenSSL).

Right. But please see inlined comment below.

This site is about networking related code in Blink. For web platform APIs such as XHR, WebSocket and EventSource, Blink side network code can also be considered as a part of network stack, so we called it "Blink network stack". Sorry about the confusion. Blink doesn't directly touch platform's low level networking API (e.g BSD socket). Blink has APIs representing abstracted networking operation (e.g. blink::WebURLLoader for resource loading including HTTP) and platform code (e.g. Chromium's content::WebURLLoaderImpl) implements the interface and performs actual network communication.

WebSocket is a bit different. We've implemented most of protocol processing (framing, parsing/generating raw handshake bytes) in Blink and Chromium provided just a pipe for binary stream. So, it's more natural to say the WebSocket network stack is in Blink.
