As many media applications become pervasive in an organization and more different devices and video, voice and data applications are used, new demands are placed on the network. It can be challenging to accommodate all application needs while reducing complexity, planning for capacity, assuring that your business critical applications (including voice and data) are not impacted and providing the best possible user experience.
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. In essence it is a set of capabilities available in Cisco router, switches and endpoints to help IT deploy, manage, troubleshoot and optimize business and collaboration applications of all types (video, voice and data!)
The Systems Management program allows you to create and enhance your workflows and reports to achieve all that leveraging the medianet media monitoring and media awareness features.
Medianet provides capabilities across a range of network and endpoint devices to enable a medianet system to send, deliver, and optimize rich-media applications.
Let's discuss the capabilities you can leverage with the Systems Management CDN Program.
Media Monitoring enhances visibility into the network. It helps you accelerate troubleshooting and assess and measure the impact of video, voice, and data applications in the network. It helps organizations:
- Troubleshoot more quickly and reduce operating costs
- Detect network issues while they occur
- Use new information and visibility to make quantifiable business decisions regarding the network.
The media monitoring capability is enabled through the following features:
Cisco IOS Performance Monitor: Helps network operators quickly find and identify problems, including fault location, that impact the quality of video, voice, and data
- Provides performance statistics (packet loss, jitter, etc.) based on analysis of user traffic
- Allows creating application class-specific threshold crossing alerts
- Provides reporting through NetFlow export and MIB
Cisco IOS Mediatrace: Helps network operators understand the status and health of a network path by collecting critical information hop by hop, on specific media streams as they traverse the network
- Layer 2 and Layer 3 node discovery, with multiple profiles of information gathering
- Dynamic configuration of a granular performance monitor policy as well as data retrieval
Cisco IOS IPSLA Video Operation (Traffic Simulator): Helps network operators validate whether a network is ready for video and rich-media applications by stressing the network path with realistic, application-specific media streams
MSI: Software component residing on endpoints, enables:
- Collection of network performance statistics (packet loss, jitter, etc.)
- Automatic triggering of a mediatrace for diagnostics upon detection of quality degradation by an endpoint
Media Awareness helps the network to become application and rich-media context aware end to end. The network works together with the video endpoints and applications for optimal quality of experience for end-users and improved visibility for IT. It helps organizations:
- Differentiate business-critical applications and determine the importance of a session based on its business value so the network can consistently provide service assurance and optimal user experience
- Extract actionable application information from the network
The solution includes:
- 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 (MSP): 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
