Fastdfs is an open source, high performance Distributed File system, his main features include: file storage, synchronization and access, design based on high availability and load balancing,Fastdfs is ideal for file-based Web sites, sample sharing and video sharing sitesFastdfs has two roles: Tracking Service (tracker) and storage services (storage), service control, dispatch files are load balanced access, storage services include: file storage, fil

To obtain the application memory usage type and time, you can view application heap updates in Device Monitor in real time: 1. Enable Device Monitor. Load the monitor tool from the 2. In the Debug Monitor window, select the application process to be viewed from the process list on the left. 3. Click Update Heap in the process list. 4. Select the Heap tab on the right panel. The Heap view displays the basic status of Heap memory usage, which is updated after each garbage collection. To view th

the processing power and bandwidth limitations of the FTP server, the download speed will drop sharply, and some users may not be able to access the server. The BT protocol differs from the FTP protocol in that the more people download, the faster the download, because each downloader downloads the downloaded data to other downloads, taking full advantage of the user's upload bandwidth. With a certain strategy to ensure faster upload speed, download speed is faster. In a very short period of ti

Fastdfs is a lightweight, distributed file system, consisting primarily of tracker server, storage server, and client, which mainly involves two points:1 Client upload file process and protocol analysis2 implementation of a simple file upload function One: The basic process of file upload Fastdfs upload a file, mainly involves the following several steps: 1 Upload the connection request, the client will send the request of uploading file to

It was ant when I got in touch with my computer and used the software to download it. Then we used the BT tool. Now there are countless software downloads, however, we still need to know about the BitTorrent protocol. This is also the specification for BT seeds and BT downloads. For normal HTTP/FTP downloads, the TCP/IP protocol is used, the BitTorrent protocol is a P2P File Transfer Protocol Based on the TCP/IP protocol, which is at the application layer of the TCP/IP structure. BitTorrent also

I believe that those who have experience in Online downloads will certainly not be unaware of the BitTorrent protocol. This protocol supports what we often call "BT" downloads. Here are some basic information about this protocol. It also includes its specific working principles, hoping to let everyone know about this part. Common HTTP/FTP downloads use the TCP/IP protocol. BitTorrent is a P2P File Transfer Protocol Based on the TCP/IP protocol, it is in the application layer of the TCP/IP struct

)The audio Listener acts as a microphone-like device. It receives input from any given audio source in the scene and plays the sound through the computer speakers. For most applications, it is most interesting to attach the listener to the camera. If the audio Listener is within the reverb region (Reverb Zone) boundary, the reverb is applied to all audible sounds in the scene. (Professional Edition only) Also, the audio Effect can be applied to the listener and will be applied to all audible sou

Fourth Chapter pricing AdvancedSo far, we have considered the sale of a product. But what happens when you sell several products, or several versions of a product at the same time?Version controlEach potential user has a psychological price to buy the product. To see our previous example, Belinda (bargain Buyer) and Stewart (student) will only use time Tracker 3000 for free. Willhelm pay a maximum of$, and Pat can accept a maximum price of$. Then we a

The downloading of a seed file into a magnetic link the downloading of the BT magnetic conversion tool can convert the BT seed file into a magnetic link. I believe many friends will use it. After all, the seed file already exists in the form of an attachment file, it also requires server storage and BT Tracker for downloading. Now the problem is that more and more servers are killed, and the server of the plug-in is almost finished. It is time to down

introduction of Peer-to-peer and DHT technology Peer-to-peer in the mind can be said to be the Internet thought/spirit/philosophy is very concentrated embodiment of common participation, transparent open, equal sharing (reminds me of the previous study, is now the crazy speculation of the "centralized" system of cloud computing). There are many applications based on Peer-to-peer technology, including file sharing, instant messaging, collaborative processing, streaming media communication and s

The update tracker accesses the object information that is being tracked by the Entity Framework. The information is not only the values stored in the object attributes

BT source code learning experience (7): Code Analysis of Tracking Server (HTTP protocol processing object)Author: Wolfenstein (neversaynever) The last time we analyzed the initialization process of the tracker class, we started to look at how the tracking server provides services.First, we analyze that the tracker processing object is httphandler, which is defined in BitTorrent/httphandler. py.

The USB Nic is divided into wireless 3G and wired, and wireless 3G Nic has been implemented by my colleagues. I recently implemented wired Nic. That is, connect to the mid through RJ45 to USB, and the driver will register the ethx network device. What I want to achieve is to operate the network device. Connectivityservice is a service that manages connections. It manages multiple network types of tracker, such as wifistatetracker and mobiledatastatet
