Carrier cloud Characteristics

1 Carrier clouds address these gaps with content delivery networks and/or dedicated virtual private networks (VPN) at OSI layers 1

(optical wavelengths), 2 (data link layer), and 3 (network layer)


Anycast Content delivery networks

1 Content delivery networks may use anycast for actual HTTP connections to their distribution centers, or for DNS.

Because most HTTP connections to such networks request static content such as images and style sheets, they are short-lived and stateless. The general stability

of routes and statelessness of connections makes anycast suitable for

this application, even though it uses TCP.


Multicast IP multicast

1 IP multicast is widely deployed in enterprises, commercial stock

exchanges, and multimedia content delivery networks. A common

enterprise use of IP multicast is for IPTV applications such as distance learning and televised company

meetings.


Rackspace Cloud - Cloud Files

1 Use cases considered as "well suited" include backing up or archiving data, serving images and videos (which are

streamed directly to the users' browsers), serving content over content

delivery networks, storing secondary static web-accessible data, developing

data storage applications, storing fluctuating and/or unpredictable amounts

of data and reducing costs.


Google platform - Network topology

1 This makes Google one of the largest and most complex content delivery networks.


Content delivery network - Content networking techniques

1 Content Delivery Networks augment the end-to-end transport network by

distributing on it a variety of intelligent applications employing techniques designed to optimize

content delivery. The resulting tightly integrated overlay uses web caching, server-Load balancing (computing)|load balancing, request routing, and

content services.https://store.theartofservice.com/the-content-delivery-networks-toolkit.html

Content delivery network - Emergence of telco CDNs

1 To address this, telecommunications service providers (TSPs) have begun to launch their own content delivery networks as a means to lessen the demands on the network backbone

and to reduce infrastructure investments.


Digital distribution

1 Specialist networks known as content delivery networks help distribute

content over the Internet by ensuring both high availability and high

performance


JQuery - Including the library

1 It is also possible to include jQuery directly from content delivery networks.


Amazon CloudFront

1 CloudFront competes with larger content delivery networks such as Akamai Technologies|Akamai and Limelight Networks. Upon launch,

Larry Dignan of ZDNet News stated that CloudFront could cause price

and margin reductions from competing CDNs.

Content Delivery Networks]


Rostelecom - History

1 On September 2013 it was announced that the company had

deployed one of the world’s largest operator content delivery networks


Smooth Streaming - Current uses

1 Post-production houses, content delivery networks and studios use

adaptive bit rate technology in order to provide consumers with higher quality video using less manpower

and fewer resources


Smooth Streaming - Benefits of adaptive bitrate streaming

1 The media and entertainment industry also benefit from adaptive bitrate

streaming. As the video space grows, content delivery networks and video

providers can provide customers with a superior viewing experience. Adaptive bitrate technology requires additional Video encoder|encoding, but simplifies the overall workflow and creates better

results.


BitGravity

1 The company was founded in 2006 and is notable because of its strategic partnership with Tata Communications which makes it one

of the new breed of content delivery networks facilitating the telecommunication industries' push into the content delivery

networks to improve the reliability and reduce the Latency

(engineering)|latency of the system.


Peer-to-peer web hosting

1 P2P web hosting may take the form of P2P web caches and Content delivery networks like Dijjer and Coral Cache which allow users to

hold copies of data from single web pages and distribute the caches with other users for faster access during

peak traffic.


HTTP/2 - Goals

1 * Support common existing use cases of HTTP, such as desktop web

browsers, mobile web browsers, web APIs, web servers at various scales,

proxy servers, reverse proxy servers, Firewall (computing)|firewalls, and

content delivery networks
