Delivery Networks Tutorial

Content Delivery Network

In a CDN, content is
copied and distributed – or replicated – to strategically dispersed servers. When a specific page or file is requested by
an authorized user, the CDN identifies the nearest server (as determined
by the minimum number of nodes between the server and the user) and disseminates
the information. By ensuring that content is delivered from the nearest
source, data transit and system response time are minimized.

The concept is analogous to a product
distribution network in which an enterprise maintains three product warehouses,
each stocked with the same merchandise. One warehouse is located in New
York, another in Chicago, and the third in Los Angeles. If a customer
located in Philadelphia orders a product, the product is shipped from the
nearest warehouse (in this case, New York). Similarly, if a customer in
Phoenix orders the same product, the product is dispatched from the warehouse
closest to Phoenix (namely, Los Angeles).

Table 1. Limelight Networks’ CDN Services and Features
Product Features
Limelight Orchestrate Platform Consisting of a global, private IP network, the
Orchestrate Platform promotes cache efficiency and connection management
features so that content is always available.

  • Caching all Web site content.
  • Supports IPv4 and IPv6 Internet protocols.
  • Offers granular control over traffic shape, failover origins, and
    multi-CDN workflows. 
  • Supports HTTP 1.1 and HTTP/2.
  • Accelerates content between the client and the CDN edge through
    TCP optimizations, compression and connections. 
  • Manages origin selection, connectivity, and failover during
    content delivery. 
  • Delivers HTTP streaming while decreasing the load on origin
    servers. 
  • Uses a set of dedicated IP addresses for delivery of zero-rated
    traffic into carriers. 
  • Content with high abandon rates can be rate limited.
  • HTTP Request and Response headers can be customized to control
    content caching and boost analytics. 
SmartPurge This CDN purging system works in near real-time to boot
stale content and functions through APIs or a graphical user
interface. 

  • Once a purge request is received, that content will no longer be
    served to end users.
  • Purges can be conducted at any portion of the Origin URl, path,
    filename, or extension.
  • Items can be purged by content tag. 
  • Prior to a purge, administrators can conduct a dry run to view
    statistics on the content that will be removed. 
  • All purged content is permanently removed from Limelight CDN.
  • Purging parameters are configurable. 
  • Dashboards allow for viewing of purge status, execution details,
    accounts, and which users requested purges. 
  • Purge executions are stored and can be used at a later time to
    create templates. 
Origin Shield By assigning one or more PoPs as a proxy, Origin Shield
helps increase cache hit efficiency. 

  • Improves workflows in Limelight and multi-CDN environments. 
  • Supports multi-CDN video streaming workflows with a single request
    to origin. 
  • Reduces requests to origin servers.
ARC Light ARC Light helps speed up content delivery. User request
and origin responses are modified to boost speed to content and offload
business logic from the application infrastructure. 
Origin Storage Limelight’s Origin Storage, along with the vendor’s
private backbone, enable quick storage retrieval and delivery on cache
miss. Automated regional replication grabs content and delivers it from
the fastest location. 

Origin Storage serves as primary origin storage or backup origin
storage for another CDN. 

Control  Control is a self-service portal for configuration of
delivery services and live events, content management, administration
and securing of the environment, usage analysis, and online support
access. 
Edge Analytics Edge Analytics consists of a suite of tools to enable
companies to better understand their content delivery. These tools
provide details regarding content, traffic, applications, and user
behavior.
