Deployung video alone will account for 57 percent of all consumer Internet traffic in The creation of video content and its distribution is a multistage process that follows a lifecycle from acquisition at the source, through production and packaging of the content, to distribution to viewers.

Here are ten key differences between the two: Fast Convergence may be enhanced with other technologies where faster recovery from failures is required, for premium video transport services.

IP/MPLS Networks: Optimize Video Transport for Service Providers

The acceleration in video deployments increases the need to address the primary challenges facing broadcasters and service providers looking for IP-based video transport solutions, including how to deliver video service-level requirements and how to effectively manage and monitor the video transport service.

Please note that Internet Explorer version 8. With video streaming applications, a receiver client requests a video that is stored on a server or produced in real time; the source server streams the multiservicr to the receiver, which starts to play the video before all of the video stream data has been received. Cisco has developed the following capabilities to provide enhanced video transport service management and monitoring.

Spatial redundancy is most useful for recovering from burst losses due to network failure events, such as link or node failures for example, in the core and potentially in the aggregation error domains. Capacity Admission Control Chapter 5: Multiervice book provides real world case studies of QoS in multiservice networks. Modular power supplies are brought online only as capacity is increased; the Cisco ASR Series consumes only the power needed to support the configuration demands of the system.

Global IP traffic grew 45 percent during to reach an annual run rate of exabytes per year or 15 exabytes per month.

These capabilities allow converged infrastructures to be shared by different services with reduced CapEx and OpEx, accelerating the deployment of premium video services and the optimal delivery of the highest-quality video.

The resulting packet loss period depends on the capabilities of the underlying network technologies and implementations; these are described in the next section. As a specific example, for multicast groups potentially equivalent to broadcast TV channelsconvergence times of about ms are realistically achievable today with optimized implementations.

Added to Favorites [ remove ]. We can define the essential SLA requirements for an IP-based video transport service in terms of delay, jitter, and packet loss. Cisco VQE technology for error recovery improves the effective network video quality while providing all subscribers with a consistent entertainment experience.

IP/MPLS Networks: Optimize Video Transport for Service Providers – Cisco

These mechanisms may be augmented with RSVP-based admission control. We can generally consider jitter to be a variation of the one-way delay for two consecutive packets. Whenever errors cannot be transparently repaired, an error detection alert is forwarded to troubleshooting systems, such as Cisco VAMS, so they can instantly initiate repair.

For example, the content may be transferred from one studio to another or from an event location such as a sporting event to a preproduction facility where the content is reworked before distribution. If the national channel lineup needs to be customized for each region, video-multiplexing equipment at the RHE can be used to renfigure the national channel lineup.

Journals Books Register Sign in Help. Presents a real world networking scenario the way the reader sees them in a device-agnostic world. The model for that book was a brilliant, unfettered approach to networking concepts that has proven itself over time to be popular with readers of beginning to intermediate networking knowledge.

Security titles from Cisco Press help networking professionals secure critical data and resources, prevent and mitigate network attacks, and build end-to-end self-defending networks. As a result, the latest network infrastructures are heavily influenced by video applications.

If you decide to participate, a new browser tab will open so you can complete the survey after you have completed your visit to this website. More information about MoFRR is available in the following documents:. With these capabilities, the Cisco CRS-1 pi be maintained, upgraded, enhanced, and scaled without requiring service interruptions.

Deploying IP and MPLS QoS for Multiservice Networks

The only book regarding Multiservice Switching architecture and configuration. These capabilities are linked with the video delivery network application intelligence to provide per-subscriber QoE information. Traffic is classified at the edge of the network and then marked using the differentiated services code point DSCP in the IP packet header into a limited number of traffic aggregates or classes.

To support these requirements, Cisco is developing a suite of networking technologies that span the range of video-optimized products and define the medianet – an intelligent network optimized for rich media. IP video transport service providers can be categorized by the types of services that they provide: The book covers architectural and implementation specific information plus recommendations for almost all the popular line cards across the various hardware platforms widely used in the market.
