Deliver Digital Media Effectively over Wide-Area Networks

The Cisco Application and Content Networking System (ACNS) is a powerful digital media delivery solution that greatly reduces redundant digital media streaming traffic traversing a WAN from the data center to branch offices over satellite and terrestrial networks.
With Cisco ACNS, organizations from the private or public sectors can deliver effective and large-scale corporate communications, on-demand training, and digital signage to remote and dispersed branch offices, schools, and stores, with high-quality and minimal impact on the network, while taking advantage of investments in converged IP WANs.
Cisco ACNS combines the technologies of transparent on-demand caching, scheduled prepositioning, and live digital broadcasting to minimize the impact over the WAN for the following types of streaming media-based applications:

• Corporate communications

• E-learning

• Digital signage

Cisco ACNS is a software product available on a range of hardware platforms, from the family of Cisco Wide Area Application Engine (WAE) Appliances to Cisco Content Engine Network Modules for the Cisco 2600, 2800, 3600, 3700, and 3800 Series Integrated Services Routers. The Cisco ACNS Content Distribution Manager (CDM) provides a flexible management system for efficient operation, automation, and central policy management of the media and content delivery network.

Product Overview

Cisco ACNS offers a comprehensive set of streaming-media features that enable high-quality and long-playing digital videos to be streamed live and simultaneously to thousands of users and media players (for example, set-top boxes [STBs]) or accessed on demand at a later time.
By caching on-demand content or prepositioning frequently accessed content and then locally fulfilling content requests, Cisco ACNS eliminates subsequent requests for the same digital media content from needing to traverse WAN links from the data center to branch offices. When multiple users or any variety of media players simultaneously join a live streaming event, Cisco ACNS carries only one stream from the source and splits that stream at the remote branch office, offloading the streaming server and significantly eliminating redundant video traffic from the WAN.
The results include improved response times to access digital media content, reduced WAN usage and costs, and increased network scalability and capacity. Cisco ACNS also provides a flexible management system for efficient operation, automation, and central management of the digital media delivery network. Coupled with transparent request redirection using the Web Cache Communication Protocol (WCCP), this network infrastructure and delivery optimization is transparent to end users and servers.
Organizations that benefit from building a digital media delivery network for streaming-media applications using Cisco ACNS Software include:

• Financial and banking organizations

• Government institutions

• Health organizations

• Medium to large retail stores

• Corporations with largely distributed regional offices

• Schools and universities (education)

• Outsourced network service providers delivering managed services to enterprises

IT departments in these organizations are required to provide streaming-media services that satisfy the needs of the entire organization:

• The network infrastructure must be able to reliably deliver streaming-media applications and provide an optimal user experience to increase productivity.

• A significant return on investment (ROI) must be generated by providing timely and effective information to employees, who can be at the local corporate office, remote branch offices worldwide, or mobile.

– For example, an e-learning video-on-demand (VoD) system deployed globally can reduce operational and training costs by reducing travel expenses and improving productivity, while at the same time increasing sales with timely dissemination of company or product information to sales or operations employees in the field.

• IT departments must quickly react to changing business needs by transparently scaling the network infrastructure to support more local and remote users and new applications.

• IT departments must keep the digital media delivery network secure and reliable.

Enterprise

• Enterprises can save operational and training costs, exponentially enhance companywide communications, and improve end-user experience and productivity by using Cisco ACNS for streaming media-based corporate communications and e-learning throughout the company.
• Cisco ACNS also minimizes employee and executive time loss and eliminates travel costs associated with onsite training.

Retail

• Retail stores can rely on Cisco ACNS to enable their digital signage applications to advertise products and news to consumers through large displays, point-of-sales kiosks, or video walls at hundreds of locations, allowing them to maximize their revenue source and accelerate the introduction of new products.
• Retail organizations would use the same digital media delivery infrastructure to improve employee productivity by delivering high-quality live scheduled video-streaming broadcasts or on-demand access to video-based training material for product promotions and corporate communications.

Education

• Schools and universities can offer classes and lessons on line to remote students, and deliver content purchased from external content providers specialized in educational content.

Managed Service Provider for Enterprises

• Managed service providers can create new business opportunities by providing live and on-demand streaming-media services to improve customer experience to enable corporate-wide live events and on-demand training.

Cisco ACNS Software runs on the Cisco WAE hardware product family. When Cisco ACNS Software is installed, the Cisco WAE Appliance can perform one of the following roles (see Figure 1):

Content Engine-Stores and serves content for client requests

Content Distribution Manager (CDM)-Web-based application for central content distribution and policy management

Content Router (optional)-Redirects client requests for content to the closest WAE

Cisco ACNS Software also runs on Cisco Content Engine Network Modules for Cisco 2600, 2800, 3600, 3700, and 3800 Series Routers. The industry's first and only router-integrated application platform for accelerating data center-based applications, the content engine network modules represent an opportunity for organizations using these routers for branch routing to add functions through a compact footprint that reduces operational costs and management complexity.

Figure 1. Primary Applications for Cisco ACNS Software

Cisco ACNS Software works with other Cisco management applications and content routing options such as:

• Cisco Digital Media System (DMS) for rich digital media creation, management, and access

• CiscoWorks software suite for network and device management

• WCCP embedded in routers and switches with Cisco IOS® Software; an alternative to content-router routing is to use an enterprise router that supports WCCP and is configured to intercept and route requests for content obtained through HTTP, Real Time Streaming Protocol (RTSP), etc.; WCCP detects client requests and routes the request to a WAE within the same network

Integration with the Cisco DMS Solution

The Cisco DMS is an easy-to-use, comprehensive solution that enables organizations to effectively create, manage, and access compelling digital media. It comprises the Cisco Digital Media Manager (DMM), the Cisco Digital Media Encoders (DMEs), and a Cisco Video Portal. Cisco DMM manages and publishes digital media and provides tools for users to add and archive media, assign metadata and keywords, preview content and manage workflow, customize the video portal interface, and schedule instant and future deployments. Cisco DMS also includes the Cisco Video Portal Reporting Tool, a Web-based reporting tool for real-time reporting on content traffic. Cisco DMS integrates with Cisco ACNS to provide optimal digital deployment across the network.
