About Forcetech

www.forcetech.netCloud streamingCloud streaming

• The concept of cloud streaming targets at providing the video over the cloud as a service, so that end users can satisfy their varieties of streaming demands as long as it can access to Internet.– Users of different terminal can obtain the same high quality of

service, with no special software or hardware required to enable streaming media

– Internet content providers can stream their videos to end users, by replying on public cloud streaming platform, instead of building their own streaming media server.

– ICPs then can share the cost and become rather scalable in serving users.

www.forcetech.netCharging modelCharging model

• content providers can avoid capital expenditure (CapEx) on hardware, software, and services, but instead renting the service of a cloud streaming platform operator only for what they use.

• Consumption is usually billed on a utility (resources consumed, like storage size, Internet bandwidth) or subscription (time-based) basis with little or no upfront cost.

ForceTech Cloud streaming solutionForceTech Cloud streaming solution

• an ecosystem solution to meet the multiple streaming needs for multiple users through a unified video

service platform

• With efficient server virtualization and organization, QoS-guaranteed streaming services on demand are

delivered through unified web access.

– live video broadcasting, video on demand ,video downloading and video conference services.

– Video viewing and video distribution

– PC, TV, mobile, MID

– P2P extended cloud of high bandwidth terminals

www.forcetech.netCloud streaming componentCloud streaming component

• Cloud streaming service system: The system includes: 1)on-demand distribution network; 2)on-demand rate transfer network; 3)multiple terminal support interface; 4) server organization and management.

– Multi-terminal accessing server is responsible for judging and accepting users that access with multiple terminals.

• The PC user gets access to the platform through WEB server, and IPTV user through EPG server and mobile terminals through WAP server.

• Cloud Streaming client side: With no reliance on client bandwidth, end terminal can obtain cloud streaming service as long as it gets access to the Internet.

– Users can either access the platform in C/S mode or P2P mode based on their needs and available bandwidth.

– In most cases, users, especially PC and TV users, are encouraged to access in P2P manner to increase the platform capacity and scalability.

– In such case, those users become part of the “extended cloud platform”.

www.forcetech.netForceTech Cloud streaming solutionForceTech Cloud streaming solution

• In such cloud streaming data centre, with the building of hardware, software and platform, different terminal users can obtain QoS-guaranteed streaming services on demand through Internet.

• The multiple terminal support enables PC end, IPTV STB, mobile phone, PDA,etc, to access the cloud streaming platform through unified web access.

• The multiple streaming service support enables live video broadcasting, video on demand and video downloading services.

• The multiple user service support enables users to either access the streaming service on the platform, or distribute streaming service through the platform.

• multi-terminal Operating

multi-screen streaming enables operators to realize unified management for different terminals (PC, TV, Mobile) and streaming services with same content and distribution.

• Cross-ISP Operating

enables operators to provide users in different IPs with the highest quality and smoothest video watching experiences possible.

• Unified Management

support large-scale server clusters and distributed management, and enables unified video distribution over a streaming server cluster platform

CDN+P2P hybrid mechanismsCDN+P2P hybrid mechanisms

• As the core side for the cloud streaming platform, the ForceP2P cloud streaming data centre is built with a hybrid of CDN and P2P framework, with the combination of virtualization and Multi-tenancy techniques.

– a trustworthy and controllable overlay

– CDN reduces end-to-end delay; P2P promotes scalability

• The whole platform contain two layers of P2P networks: 1) Structured Edge Server P2P: to optimally place edge servers and to reload traffic from full-loaded server to less-loaded server. 2) Distributed User P2P: to employ a pure multiple-source to multiple-receiver P2P to achieve maximum scalability in each cluster.

Force P2P Database

Server (FDBS)

-FDBS is responsible for taking all dynamic data the FCCS cluster needs to store and sending

the proper data information cached in servers to FCCS.

Force P2P Central

Control Server

(FCCS)Cluster

-FCCS handles all servers, mainly for the server information management and interaction.

-FCCS conducts the load analysis of the servers with efficient algorithm and assigns the most

proper Force CDN node or FTDS server as the seed. The seeding node is selected with load and

connectivity analysis, incorporating principles like nearest location, best seed and best

connection number.

Force P2P CDN

Server

- FCDN is between FCCS server and FTDS server, responsible for inter-domain content handling

and distribution in cross-domain network. When FTDS server is far from FCCS server, FCDN

server will take responsibility for real-time data delivery and distribution in its domain.

Force P2P

Transmission

Uploading

Server(FTUS)

- Directly respond to user upload request, handle user uploaded content, integrate into full

stream, upload the video stream to streaming server and distribute to other users.

-Directly obtain collected live video stream, push live stream to streaming server, form live

channel for live video distribution.

Force P2P

Transmission and

Delivery Server (FTD

S ）

-FTDS (Force Transmission and Delivery Server) is at the bottom layer of FCCS and FCDN, and

is responsible for accepting node joining and streaming the node, with the guide of FCCS. FTDS

receives file and live content distributed from FCCS and FCDN.

-FTDS mainly serves the client peer for responding user request and provides requested live

data/stream to users.

Intelligent P2P assitance—enabling “more user= higher quliaty+lower cost” through sub cloudIntelligent P2P assitance—enabling “more user= higher quliaty+lower cost” through sub cloud

• Certain Client with high bandwidth(e.g PC) are enabled to share content in P2P manner to decrease the pressure of cloud data centers

• the combination of P2P networks around those servers facilitates peers to freely transmit within their P2P clusters to achieve maximum scalability
