A medianet is an end-to-end architecture for a network comprising advanced, intelligent technologies and devices in a platform optimized for the delivery of rich-media experiences. A medianet has the following characteristics:
• Media-aware: Can detect and optimize different media and application types (telepresence, video surveillance, desktop collaboration, and streaming media) to deliver the best experience
• Endpoint-aware: Automatically detects and configures media endpoints
• Network-aware: Can detect and respond to changes in device, connection, and service availability
With the increasing adoption of new video and rich-media applications, medianet technologies become critically important to address challenges associated with the transmission of video, voice, and data over the network, including ensuring predictability, performance, quality, and security.
By accelerating deployment of applications, minimizing complexity and ongoing operational costs, increasing visibility into the network, and helping to scale the infrastructure for the best quality of experience (QoE), medianet technologies help address these challenges.
Capabilities and Benefits
Cisco® Networking Capabilities for Medianet extend the boundary of networks to the endpoints, creating tight integration between intelligent network services and the rich-media applications delivered over a variety of endpoints. Cisco endpoints are equipped with the Media Services Interface (MSI), a software component that enables endpoints to consistently take advantage of intelligent network services to improve the quality of experience and reduce the cost of deployment and operations. MSI enables:
• The network to become media-aware so that the network can intelligently apply critical network services
• Rich-media applications to become network-aware, enabling them to dynamically adapt to network conditions and improve the range of troubleshooting options through tighter network integration
Cisco Networking Capabilities for Medianet provides capabilities across a range of network and endpoint devices to enable a medianet system to send, deliver, and optimize rich-media applications. Today's Cisco Networking Capabilities for Medianet focuses on reducing IT costs and the complexity of deploying video as well as improving the video experience. The capabilities also provide much improved visibility into the network to accelerate troubleshooting and the ability to assess the impact of voice, video, and data on the network.
Table 1 describes the capabilities, components, benefits, and features of Cisco Networking Capabilities 2.x for Medianet. The appendix discusses Cisco Networking Capabilities 1.0 for Medianet.

Helps differentiate business critical applications for service assurance, consistency and optimal quality of user experience end-to-end.
• Flow Metadata: Manages and transfers application attributes to the network allowing appropriate policies to be applied at each hop, end to end
• Media Services Proxy: Uses light weight deep packet inspection techniques to snoop standard based signaling protocols to produce flow metadata attributes that can then allow appropriate policies to be applied at each hop, end to end
• Network Based Application Recognition 2 (NBAR2): Enables protocol detection for a network which is the process by which the system determines that a particular network flow is from a specific application.
• Media Services Interface (MSI): Residing on endpoints, explicitly signals application context attributes (flow metadata) to the network

Cisco Prime Infrastructure accelerates business and network transformation with unified lifecycle management and application visibility. It provides a single integrated solution for comprehensive lifecycle management of the wired/wireless access, campus, and branch networks, and rich visibility into end-user connectivity and application performance assurance issues.
Cisco Prime Infrastructure collects data from Medianet-enabled devices to provide visibility into voice statistics enterprise-wide and to help accelerate voice/video troubleshooting, while reducing instrumentation configuration and data collection complexity. In addition to Mediatrace, Cisco Prime Infrastructure collects data from a broad array of embedded technologies such as NetFlow, IOS Performance Agent, and SNMP. This permits network operators to quickly and easily gain comprehensive insights into network and application performance to more effectively manage the services their network delivers.
Cisco Prime LAN Management Solution (LMS) is an integrated suite of management functions that simplify the configuration, administration, monitoring, and troubleshooting of Borderless Networks.
The Medianet Work Center provides day-1 through day-N workflows for assessing, preparing, and setting-up auto-configuration and location settings to simplify the provisioning and tracking of Medianet endpoints such as digital media players and IP video surveillance cameras. The Medianet workflows enable the network operator to select the type of Medianet to provision, automatically prepare the network for deployment and check to ensure the appropriate location attributes are configured for tracking and monitoring purposes, reducing the chance for errors and time required to set-up an end-to-end video infrastructure.
Cisco Prime Collaboration provides accelerated, automated provisioning of Cisco® Unified Communications and continuous real-time monitoring and advanced troubleshooting tools for Cisco Unified Communications and Cisco TelePresence® systems including the underlying transport infrastructures.
The solution provides efficient, integrated service assurance management through a single, consolidated view of the Cisco voice and video collaboration environment. Real-time monitoring of voice and video networks includes dashboard summaries and alarm correlation. The solution proactively notifies operators of issues and facilitates speedy resolution of problems through proactive fault detection and rapid isolation using purpose-built diagnostic tools.
