Cisco® Content Delivery Engines (CDEs) are a family of carrier-class appliances that power the Cisco Videoscape Distribution Suite (VDS) for Internet and TV streaming products. VDS is an innovative, network-based modular platform for video delivery. Generation 3 CDE 250 models span a wide range of solid state and hard disk models, which extend the performance and features of the Cisco CDE series.

Cisco VDS delivers an exceptional level of scalability and reliability while giving service providers a distinct service-velocity advantage in supporting the next generation of personalized entertainment and interactive media. The Cisco VDS platform combines Cisco CDEs with Cisco Content Delivery Applications (CDAs), software elements that provide ingest, storage, caching, streaming, and other real-time, scalable, and resilient capabilities. Cisco CDEs and CDAs can be flexibly configured to support a variety of networked value-added services that service providers can rapidly deploy to attract and retain subscribers.
Networked Cisco CDEs work together to form a scalable, flexible, and highly available system that allows service providers to rapidly deploy high-value services such as Video on Demand (VoD), Live Streaming, Time-Shift TV (TSTV), and cloud DVR (cDVR).

Cisco CDE and CDA Product Overview

Cisco CDAs can be grouped into the following service types:

• TV Streaming (VDS TV): Content delivery to TV sets through cable or IPTV set-top boxes

• Internet Streaming (VDS IS): Content delivery to IP devices connected to the Internet

• Cisco Visual Quality Experience (VQE): Error repair, statistics gathering, and channel change-time acceleration

Table 1 provides a mapping between the Cisco CDAs and the various CDE models. Cisco CDE 250 models are shown in bold. To obtain detailed information about all Cisco CDAs, please refer to the Cisco CDA product literature.

Cisco CDE Features and Benefits

Designed to increase flexibility, Cisco Content Delivery Engines can be grouped into arrays that operate as a single logical system. Service providers can easily expand capacity by attaching additional Cisco CDEs to the array, thereby achieving almost unlimited video storage and streaming capacity. The Cisco Videoscape Distribution Suite employs a hierarchical storage design that allows service providers to maintain huge content libraries while actually simplifying content storage management.
Cisco CDEs adapt automatically to unpredictable and rapidly changing traffic patterns. The platform preserves video programming in a common, shared storage array that is instantly accessible for streaming anywhere in the network. Cisco Intelligent Caching technology automates the distribution of video content between Cisco CDEs by responding dynamically to actual viewer demand and popularity trends. This adaptive content distribution model helps ensure that the content that is most popular at any point in time at each network node is always available in local storage, significantly reducing the bandwidth burden on the network backbone. This flexible architecture and the effectively unlimited scalability of content libraries make the Cisco VDS an attractive solution for efficiently and cost-effectively delivering "long-tail" content, network-based time-shifted programming, and user-generated content. This feature helps increase network scalability while reducing capital expenditures (CapEx) and operating expenses (OpEx).
Cisco CDEs are also designed for fault-tolerant operation. They can share states and work together as a single logical pool of resources that can be dynamically reallocated across the network's available hardware capacity in response to service requests. In the event of hardware failure, the Cisco VDS immediately delegates the functions being performed by the failed device to other Cisco CDEs in the network. Furthermore, the system automatically discovers the addition or removal of a Cisco CDE and reconfigures itself without service disruption or manual intervention, vastly simplifying maintenance and upgrade operations.
A network populated with Cisco CDEs becomes a platform upon which new services and applications can be layered over time and deployed much more quickly than was possible in the past. The platform unleashes the power of IP networking technology by creating a video infrastructure capable of delivering nonstop availability, high scalability, and low total cost of ownership. Taking advantage of the extensible architecture of the Cisco VDS, operators can deploy on-demand video services today with the knowledge that they can expand their services to support real-time applications and multiple forms of interactive media content delivered to many types of devices.
Features and benefits of the Cisco Content Delivery Engines are summarized in Table 2.

Table 2. Cisco Content Delivery Engines Features and Benefits

Feature

Benefit

Industry-leading MPEG2TSstream density

With up to 8000 MPEG2 standard-definition (SD) streams in a two-rack-unit (2RU) form factor, the Cisco CDE 250 Dense TV Streamer offers industry-leading video streaming density (4000 SD streams per RU). This translates to over 176,000 MPEG2 SD streams served with a single rack, optimizing space requirements and reducing total ownership costs.

Industry-leading HTTP Adaptive Bit Rate stream density

With over 30 Gbps HTTP streaming in a two-rack-unit (2RU) form factor, the Cisco CDE 250 Internet Streamer offers industry-leading video streaming for HTTP Adaptive Bit Rate formats from Apple, Microsoft, and Adobe. This translates to over 660 Gbps served with a single rack, optimizing space requirements and reducing total ownership costs.

High-performance processing

Eight CPU* cores promote high performance for computationally intensive tasks such as sustained video streaming operations or per-stream targeted ad insertion.

High-density persistent MPEG2T storage

The Cisco CDE 250 combined with VDS-TV CDA offers a high-end Content Library capable of reliably storing up to 12,000 hours of MPEG2 SD content in a two-rack-unit (2RU) form factor, allowing service providers to expand their content library with a small number of library servers.

High-performance content acquisition

Cisco CDEs combined with VDS-TV CDAs are capable of simultaneously ingesting up to 200 MPEG2 SD streams, providing highly scalable content acquisition of real-time live channels for time-shift TV services.

Flash memory SSD technology

Flash memory SSD technology complements hard-disk-drive (HDD) options for certain Cisco CDE configurations. The technology is used for video cache and transaction logging to lower operating costs and lay the foundation for even better performance and scale.

Solid-State Boot Device

8 GB of compact flash memory helps ensure reliable bootup operations with ample capacity to spare.

Dual-port management access

Two dedicated management ports are available in addition to the ingest, fill, and streaming ports to simplify connectivity and manageability.

High-efficiency redundant power supply

The Cisco CDE 250 base systems support either AC or DC dual, high-efficiency power supplies for lower power consumption and a simplified sparing strategy.

Nonstop service availability

Unique failover and resiliency features help ensure that hardware failures do not bring down the network and cause service outages.

Logical server arrays

VDS-TV resource pooling and load balancing allow Cisco CDEs to be networked into logical server arrays that can provide effectively unlimited amounts of content storage (content library array), content cache (caching node array), and streaming capacity (streamer array) throughout the network.

Additional streaming or storage capacity can be added to the array without outages or service interruption. The Cisco VDS TV detects the addition or removal of Cisco CDEs from the logical array and optimally load balances the entire resource pool.

Independent scaling of the content library size and stream count allows flexibility in capital expenditures.

Multifunction capabilities

Cisco CDE models are built on a few selected base systems with minor differences among the available configurations, simplifying personnel training and equipment sparing strategies.

Generation 3 technology

Cisco CDE 250 offers world-class performance through leading-edge server technology, a directly attached storage architecture, and 10-Gigabit Ethernet connectivity.

Generation 3 flexibility

Cisco CDE 250 offers a flexible Cache Storage Bundle structure, supporting storage upgrade paths and server repurposing opportunities.

Generation 3 manageability

Cisco CDE 250 supports lights out management capability through support of the Intel Intelligent Platform Management Interface (IPMI) and a dedicated Ethernet port.

* On all models except Cisco CDE 205, which has four CPU cores.

Generation 3 Content Delivery Engines: Cisco CDE 250 Models

The latest generation of Cisco Content Delivery Engines, the Cisco CDE 250, employs leading-edge server technology to deliver higher scalability, performance, and flexibility in a dense 2RU design. A multitier product structure provides flexibility at the storage system level while simplifying the underlying server product across all applications. Each Cisco CDE 250 storage bundle is optimized for the Cisco Content Delivery Applications (CDAs) that are supported on it, as shown in Table 3. The 10-Gigabit Ethernet I/O uses Enhanced Small Form-Factor Pluggable (SFP+) modules to support both fiber and copper media on a per-port basis.
