Nebula CDN[edit]

Nebula(Chinese: 星域; literally: "asteroid field") CDN is a CDN product which launched by Shenzhen Onething Technologies Co., Ltd, a wholly owned subsidiary of Xunlei, in June 2015. Different from traditional CDN, Nebula CDN make use of idle bandwidth that share by users.[14] In order to participate in this plan, users can buy a network device(ZhuanQianBao or OneThing Cloud) from Xunlei. In return, Xunlei gives the user virtual token as a reward. As the civil broadband prices far below the broadband prices for enterprises in China, Nebula CDN's enterprise-side prices lower than its competitors.[15] The business customers of Nebula CDN include Xiaomi, iQiyi, Momo, Insta360, Bilibili and Xunlei itself.[16] In August 2017, Xunlei announced they received an official license of CDN operating from Ministry of industry and information industry of China.[17]

StellarCloud[edit]

StellarCloud(Chinese:星域云) is a shared cloud computing platform which expands Xunlei's existing Content Delivery Network (CDN) services to Infrastructure as a Service (IaaS), offering Edge Computing, Function Computing and Shared CDN (SCDN) solutions[18]. StellarCloud is created to help companies in their transition to cloud, including content delivery, live streaming, data storage and artificial intelligence (AI). Supported by over 1.5 million computing nodes, StellarCloud can offer as much as 30T bandwidth capacity and 1500 PB storage capacity.

OneThing Cloud[edit]

OneThingCloud(Chinese: 玩客云), a private cloud specifically designed for people who pursue the digital entertainment life with high quality, provides people with quick download, storage and removing at any time, file management, remote control, multimedia entertainment and other functions.[19] OneThing Cloud is a multi-functional product for the internet users: it is a LinkToken mining machine, which can produce LinkToken(a virtual token) every day if the user allow to share their network bandwidth to Nebula CDN; it is a mini NAS server, and users can upload photos or download internet resource to the storage device of OneThing Cloud, which rely on Xunlei's network acceleration service; the users can also use the device as a home multimedia terminal, which can project videos to TV through DLNA.

OneThingCloud, the best partner of mobile phones, can help users enjoy the effect that the mobile phone’s memory is expanded for hundred times. Photos, documents and videos stored in the mobile phones can be quickly and synchronously accessed at anytime and anywhere. Users can buy mobile phones with the smallest memory, and enjoy the achievements of maximum memory through OneThingCloud, including taking more photos and storing more videos;[20]

OneThingCloud can function as a PC with low energy consumption and cost. Phones and TVs can serve as screens for OneThingCloud, through which, the user can enjoy digital entertainment, business, storage and other functions and does not need to open the computer at home;

OneThingCloud, with light-NAS function, is a portable storage needing no concern about the loss. Users do not need to carry U disk or mobile hard disk, and are able to access, call and edit documents in hard disks or U disks connected with OneThingCloud through the mobile phone; [21]

OneThing Cloud is an intelligent and environmental product, which also shoulders the function of crowd sourced computing node.

With the rapid development of big data, artificial intelligence, 4K content, AI, VR and other technologies, the explosive growth of demands for CPU, bandwidth, storage and other computing resources of the whole society has never been seen in history, while the driving force of computing cost decline - Moore's Law has almost lost its power, which generates a sharp social contradiction.[22] The path found by Xunlei is the crowd sourced computing. That is, the user can share idle computing resources when using OneThing Cloud just through the participation in the OneThing Cloud User Reward Program. These idle resources can be transferred into shared-computing services through Xunlei's innovative technology, thus greatly reducing operating costs of internet companies, which now have been applied in the field of CDN. Since 2014, Xunlei has invested more than USD 100 million in research and development, and will continue to invest for the crowd sourced computing.[23]

Being attracted by powerful product functions and social values, many users are stampeded into buying OneThing Cloud which has obtained 100% favorable rate on JD.com.[24]

ThunderChain[edit]

In April 2018[25], Xunlei launched ThunderChain (Chinese: 迅雷链), a high-performance blockchain platform, which can concurrently conduct millions of transactions per second (TPS). Based on Xunlei’s proprietary homogeneous multichain framework, ThunderChain is designed to realize confirmation and interaction among homogeneous chains and enable multiple transactions to be executed on different chains in parallel. An optimized practical byzantine fault tolerance (PBFT) is adopted by ThunderChain as its consensus model which results in low latency and makes it possible to generate one block per second. PBFT, as a consistency algorithm, is also able to avoid soft fork. ThunderChain supports smart contracts written in solidity language and is compatible with Ethereum Virtual Machine (EVM), making it easy to migrate applications from other blockchain platforms. [26]

ThunderChain File System[edit]

ThunderChain File System (TCFS), based on Xunlei’s proprietary distributed technology and millions of shared computing nodes, is a distributed file system for data storage and authorized distribution. It is built specifically for blockchain platforms including ThunderChain and other platforms. Blockchain developers and enterprises can build decentralized applications (DApps) with distributed data storage and integration, possessing the improved capabilities in openness, transparency, non-temper ability, traceability, reliability, security and encryption, mass storage and authorization.[27]

Xunlei Kankan[edit]

Xunlei Kankan, also known as Kankan, is a video-on-demand service with a web interface as well as a client application. Xunlei Kankan is also available on mobile platforms including Android and iOS (including iPhone and Kankan HD for iPad). In 2015, Xunlei sold its entire stake in Xunlei Kankan to Beijing Nesound International Media Corp., Ltd. for a total consideration of RMB130 million. [28]

Others[edit]

In addition to the above products, the company also produces software such as a media player, a game accelerator, a live streaming video platform and online games.[29]

Facilities[edit]

Headquarters and offices[edit]

Xunlei Building, the new headquarters building of Xunlei, is under construction and expected to be completed in 2020. Xunlei Building is located in Shenzhen Nanshan District, adjacent to Shenzhen Metro Line 1 and Line 2. The building has 30 floors, and the total construction area of the building is about 65,000 square meters.[30]

Concerns and criticisms[edit]

LinkToken[edit]

LinkToken is one kind of virtual token[31] issued by Xunlei, and this token must be obtained through the sharing of user's network bandwidth, storage space or other resources. Xunlei said this token can be used to pay for network acceleration services, cloud storage services and other internet content. The company explained that the digital token would allow transparent bookkeeping for the computing resources that users share on the company's cloud platform. [32] On account of the prohibition of virtual currency trading and ICO in China, Xunlei declare that LinkToken does not constitute an ICO and it cannot be purchased or traded in cash[33], and the company has issued lawyer's letters to third-party trading platforms, requiring them to stop LinkToken trading activities.[34] Nevertheless, the trading price of the token still rose 30 times in a month on some unofficial trading platforms, and some critics assert that the token is too speculative and may face some regulatory risks.[35]

On 17 September 2018, Xunlei entered into a strategic partnership with Newland Hi-Tech Group Co., Ltd. In connection with the Strategic Partnership, Xunlei also entered into a series of transactions with Beijing LinkChain Co., Ltd., an associated company of Newland, to transfer the exclusive right to operate LinkToken program within mainland China, including without limitation, the formulation, amendment and execution of the rules governing the rewarding of LinkToken to users, LinkToken Pocket and the LinkToken Mall, and the related assets and liabilities to Beijing LinkChain (the “Transfer”). Upon the completion of this Transfer, Xunlei will cease operating the LinkToken program within mainland China. This Transfer will allow Xunlei to put more focus on research and development of the underlying blockchain technology and infrastructure, such as ThunderChain and ThunderChain File System (TCFS). [36]

File sharing[edit]

Xunlei is different from P2P tools in that it does not support active file sharing. While copyright advocates view Xunlei as a P2P tool that facilitates copyright violation, P2P advocates criticize Xunlei as a leech with much more downloading than uploading. Also it is often observed that Xunlei prioritizes file sharing with Xunlei users rather than other client users. Many pure P2P tools have blocked Xunlei, although this trend weakened after Xunlei began balancing the number of downloads and uploads.

Xunlei sets up its own storage servers to backup the files which are not active or shared any longer. This feature is named as High-Speed Channel and allows Xunlei users retrieve data faster than others. But only paying users have access to these servers and download files.
