Acu Manager

Manages users, content and AcuStreams. Working in conjunction with AcuSTUDIO, AcuConference and AcuStreams, speeds up the delivery of multimedia content over a network infrastructure.

Rich Media Core Engine Scalable Architecture

AcuManager rich media core engine


AcuManager is the heart of AcuLearn’s Content Delivery Network (CDN) architecture. It works with AcuStudio to speed up delivery of multimedia contents over your network infrastructure, live webcast to mass audience and AcuConference for real time collaboration using its built-in Multipoint Conferencing Unit (MCU). AcuManager is able to manage detail reports, security access, virtual cluster, schedule recording and many others administrator functions. Extending the CDN functionality using AcuStreams, a large number of participants can be supported at the same time without overloading the WAN bandwidth.

Scalable Architecture

AcuLearn rich media communication solution suite is used and proven by Telecom operators, Corporations and major universities connecting thousands of people together.

True “all in one” rich media solution

On one single scalable architecture, AcuLearn delivers all your rich media communication needs with the provision of live web broadcasts, real time interactive conference/ work collaboration and creation and distribution of on demand learning content.

Working within your secure network

AcuLearn solution is used in places with high network security demands. Our solutions work with proxy server, domain authentication and most types of Microsoft ISA security settings.

Overcome bandwidth limitations

The issues of limited network bandwidth to support multimedia applications like video on demand, live-webcast video, video conference or web collaboration can be avoided by deploying CDN to deliver contents at the network edge instead of central server. CDN is an effective way to scale up the network without requiring major upgrades to network infrastructure and bandwidth.
The combination of AcuManager and AcuStream forms the CDN infrastructure. AcuManager is the core of the CDN. Any number of AcuStreams can be deployed at the network edge to localize traffic to serves users in their vicinities.

Optimal Performance Redirection

Conference participants are automatically redirected to the AcuStream with the best network response. The respective AcuStreams will interconnect to reduce international bandwidth utilization.


Central Management Console

Using Internet Explorer browser, the administrator can connect to the AcuManager to manage and configure the entire CDN, including the AcuStreams.

Firewall Friendly

When AcuManager receive content from AcuStudio, it replicates content to the edge AcuStream servers using firewall friendly HTTP pull protocols. Addition or deletion of contents are done via the AcuManager.  The AcuManager synchronizes the changes across all the AcuStreams.

Broadcast Server

AcuManager and AcuStream acts as broadcast relay nodes.  AcuManager will assign live video streams according to the policies set by the administrator. User’s videos are streamed directly from AcuStream if the setup encompass an AcuStream. AcuStream will interconnect to other AcuStreams automatically to allow scalability to 900, 000 concurrent connections.


AcuManager works with your network security. Access to the system or its content can be controlled by authenticating by setting Access Code or User groups.

Controlled content replication

Replication time can be configured to only allow content replication to occur during off-peak hours, e.g. from midnight, to avoid disrupting critical applications during business hours.

Virtual Content Delivery Network

For large network deployment you can create virtual groups to serve different subsidiaries. You can also create different class of services using VCDN as well. Users can assigned to these virtual network groups.
Enterprise and ASP system We understand the difference in the workflow between the enterprise and ASP environment. AcuManager contain 2 different access interfaces to serve both environments.

Call Detail Records

Every access for video on demand content, live webcast and conference are logged into CDR. This is useful for inter-departmental and customer billing.


When a session is created for AcuStudio, AcuLive or AcuConference. AcuManager will send an email to the author together with the access hyperlink and instructions/system requirements to access the session. Author simply need to forward this email to his participants.
