CPS1000 Cluster Manager

Advanced on-demand services have become an increasingly important part of a multichannel video offering. Video Service Providers need to optimize their storage, streaming and network bandwidth costs in the face of real-time ingest of live content, expanding content libraries and flattening concurrency curves, resulting in the much discussed "long tail."

CPS1000 Cluster Manager (CPS1000-CM) is the first component of the Motorola Content Propagation System. CPS1000-CM provides cluster management between the on-demand servers and the operator's back office system, managing the distribution of content and stream allocation.

The CPS1000-CM optimizes storage, streaming and network resources, and improves fault resiliency for a cluster of co-located or geographically distributed cluster elements.

CPS1000-CM utilizes Adaptive Media Management, our approach to intelligent distribution of content and streaming resources, across the appropriate storage and streaming technologies.

Features

Highlights

  • Intelligently manages placement of content and streams across the on-demand network
  • Optimizes streaming, storage and network resources through Adaptive Media Management
  • Supports multiple storage architectures for maximum flexibility
  • Distributes content both proactively based on metadata and reactively based on usage patterns
  • Uses prevailing industry standards designed to support third-party servers


Key Features
Proactive Content Placement

  • Reliable, full replication of content across an entire cluster
  • Rules-Driven Content Placement optimizes placement of content in cluster based on metadata

Reactive Content Placement
  • Library Balancer ensures all servers have the entire library in a fully replicated environment
  • Demand-Driven Content Placement uses usage statistics to best position content across the cluster.

Stream Placement Options
  • Content Affinity Load Balancing assigns streams to servers currently streaming the content to more efficiently use streaming resources and storage bandwidth
  • Automatically redirects streams to most efficient resource
  • Supports propagate and stream when local server does not have required content

Fault Resiliency
  • Automatically retries failed streams on another server in the cluster
  • Distributed deployment model eliminates single point of failure for centralized ingest and stream processing
  • Automatically detects and recovers from possible failure scenarios
  • Enables the creation of seamless maintenance windows for servers in the cluster


Storage Architecture Supported
Fully Replicated

  • Replicates entire library on each server
  • Single point of ingest saves bandwidth
  • Library Balancing maintains content synchronization
  • Stream Affinity selects optimal server to minimize streaming resources and optimize storage bandwidth
  • Improved fault tolerance/resiliency

Shared Storage
  • Central storage of entire library
  • Rules-Driven Content Placement proactively places content on servers in optimized fashion
  • Demand-Driven Content Placement reactively optimizes content placement
  • Supports Library Server (NAS w/ NFS, CIFS, etc.)
  • Directs stream requests to server with content or propagates to “local” server
