Delivering a Top Class Mobile Video Experience

Allot VideoClass is an application-aware video optimization system that is fully integrated with Allot Service Gateway and its powerful service enablement environment. It allows mobile service providers to dramatically improve the quality and efficiency of video delivery by optimizing for real-time network conditions and for each mobile connection. This unique dual optimization capability enables the highest Quality of Experience (QoE) for video consumers, while minimizing the bandwidth required by the video stream.

Integrating innovative technologies for video optimization

Allot VideoClass integrates the most innovative technologies into a harmonious solution for effective and efficient video optimization. It employs human perception models to reduce non-essential data and allots just the right amount of bandwidth to each video application. Allot VideoClass intelligently paces the stream to ensure uninterrupted playback and dynamically transrates video content and adapts delivery based on real-time network conditions – all the while keeping detailed records of each video session. Allot Service Gateway steers only the relevant traffic to Allot VideoClass (which may be hosted within the Gateway platform or externally), allowing you to optimize with extreme efficiency and a smaller deployment footprint.

With Allot VideoClass you can:

  • Reduce bandwidth consumption by 30-50% on expensive RAN and backhaul capacity, and thereby avoid or delay network expansion and CAPEX outlay
  • Lower operational expenses by reducing “wasted” bandwidth while providing the same perceived QoE
  • Ensure a consistently great video experience by preventing stalls and buffering delays that affect customer satisfaction and loyalty
  • Create new revenue opportunities through mobile data service packages designed specifically for high-volume video consumers
  • Gain insight on consumer behavior through detailed information of video usage

Key technologies

Allot VideoClass integrates the most innovative technologies into a harmonious solution for effective and efficient video optimization.

Application-aware bandwidth allocation

Assigns just the right amount of bandwidth to each video application, allowing more simultaneous sessions on the available bandwidth.

Content-aware bandwidth reduction

Employs human perception models to reduce non-essential data. Network-aware adaptation shapes video delivery to match real-time RF network conditions.

Client buffer management

Intelligently paces the video, sending just enough data to enable continuous, uninterrupted playback. Network estimation continuously monitors each video session to determine whether the subscriber’s current conditions are adequate for the content. If not, then reduction and adaptation features are activated to optimize the flow and maximize subscriber QoE.

Inline transrating

Adapts video content to network conditions in real-time, without the expense or scalability concerns of complete transcoding. The Allot VideoClass transrating engine checks video frames and their properties and reduces only those parts of the content that a subscriber would not notice, reducing bandwidth while providing the same perceived QoE. Transrating reduces delivery bandwidth only during drops in available bandwidth, dynamically changing to match network conditions. Content adaptation selects the most appropriate delivery technology based on the original content format and specific device capabilities. This enables dynamic real-time adaptation of content for each subscriber session, even when the original content format does not support dynamic adaption (e.g. MP4).

Flexible policy management

Allot VideoClass provides a flexible, rules-based policy manager tool to customize optimization parameters on a session-by-session basis. Policy rules consist of Policy Attributes that define WHEN to apply the policy rule to a video session; and Policy Profiles that define WHAT optimization actions to apply to the video session. Supported Policy Attributes include URL server domain, content type (e.g., Flash, MP4), time, device type, subscriber (class token from the policy server), and client IP address.

Flexible deployment options

Allot VideoClass can be deployed in the Allot Service Gateway platform as either a standalone, inline layer 2 bump-in-the-wire mode, or as a fully integrated service that leverages caching and other services hosted in the platform. This tight integration provides a very cost-effective and holistic approach to bandwidth management and delivery optimization of OTT video.

Traffic steering and load balancing

Allot Service Gateway reduces the deployment footprint by steering only relevant video traffic to the optimization engine, while leaving non-video traffic untouched. Integrated load balancing also eliminates the need for costly external load balancers.

Virtualized optimization functions

Allot VideoClass supports deployment schemes for virtualized network functions. When deployed in the cloud, its video optimization functions leverage the granular traffic detection and steering of Allot Service Gateway, enabling video delivery services that are highly scalable and adaptive to network conditions. Virtualized Allot VideoClass functions may be deployed on standard x86 server or server blades, as well as ATCA equipment.

Comprehensive reporting and analytics

Detailed records are kept for each video session, allowing the monitoring of mobile video traffic and subscriber usage patterns. Analytics reports provide daily and hourly breakdowns of traffic volume, video usage, optimization savings, device types, most popular content sites, and other valuable data. Reporting and analytics data can be exported to a data warehouse or viewed via the online GUI.

Open architecture

Standard interfaces, protocols and APIs facilitate rapid and trouble-free integration in your PCC environment and with third-party network and subscriber services.

High scalability

Pay-as-you-grow deployment reduces initial capital outlay and allows you to add services or upgrade capacity at any time.

Carrier-grade design

Allot VideoClass is engineered to AdvancedTCA® standards with N+1 redundancy schemes for deployment in service provider networks.
