[Asking] About the "Computer Networking - A Top Down Approach, 7th" book

linhdangduy commented 4 years ago

First of all, thanks for your contributions. Also, I want to say sorry because I'm going to asking question in English at a Chinese repository.

I searched about the "Computer Networking - A Top Down Approach, 7th" book on internet and end up at the following link of this repository. https://github.com/QSCTech/zju-icicles/blob/master/%E8%AE%A1%E7%AE%97%E6%9C%BA%E7%BD%91%E7%BB%9C%E5%9F%BA%E7%A1%80/%E6%95%99%E6%9D%90/Computer%20Networking%20-%20A%20Top%20Down%20Approach%2C%207th%2C%20converted.pdf

I want to ask two questions:

Does this public copy is allowed by it's authors, or is there an agreement between your organization and authors of the book? (If possible, could you give me the document, link or something that proved the allowance?)
If (1)'s answer is like "yes, this public copy is allowed by book's authors", do I have the right to download this copy use for personal purpose? (Because I'm working as a software engineer now, and I'm not a student of Zhejiang University.)

Below is some context about what I read/understand when finding about this repo and the book:

What did I read in this repo

I have read the Readme of the repo (by using google translate tool).

At 警告 , I see that you have defined which content is not allowed to upload.
At 许可, I read the license.

What did I find about the book on internet:

https://www.pearson.com/us/higher-education/program/Kurose-Computer-Networking-A-Top-Down-Approach-7th-Edition/PGM1101673.html At Pearson website, I see that there are two option for audience of the book. You can only request a copy of the book if you are an educator.

PS

Sorry if I being rude by asking like this (please correct me if I missing something and don't understand properly about the copy right and this repo), I just want to make sure that reading this copy does not violate any copyright related to this awesome book.
