Carrier Delivery option
What is content delivery?
Content delivery is the method of providing web-based media over a particular medium, such as the Internet or television broadcast channels. For any media consumed online, it must be delivered from a first server—the originating server—to a second server—the cache server. This includes music videos, webpages, television shows, videogames and all other online, web-based content.
Online content delivery distributes information to duplicate servers to maintain web-based content. This is known as content caching. Content caching decreases loading time, enables efficient delivery and decentralizes data handling tasks. This prevents denial-of-service (DoS) attacks.
Key takeaways
- Content delivery works through three steps: web redirection, URL selection, and delivery.
- Content can be delivered through downloading or streaming.
- Different content types can be delivered in different ways to create a truly omnichannel experience.
- Content delivery networks (CDNs) can help decrease loading time, improve content availability and redundancy, enhance webpage security, and decrease bandwidth expenses.
How content delivery works
The acceleration and proliferation of Internet-based content have raised the importance of stable content delivery systems. This includes video-on-demand (VoD), downloadable content, streaming services and everything else provided online. To meet demand, ISPs have increased scalability, quality of services and network reliability.
Content delivery works through three steps.
1. Web redirection
Cache servers are placed at major Internet access points worldwide. These secondary cache servers then use a special routing code to redirect the webpage request to the closest server.
These special routing redirection codes include:
- Hypertext Transfer Protocol (HTTP) redirection
- IP redirection
- Domain Name System (DNS) redirection
2. URL selection
The web user then selects a given Uniform Resource Locator (URL) that reroutes the request away from the website’s originating server and directs it instead to a secondary cache server closer to the user.
3. Delivery
The secondary cache server then establishes which content is held in the cache, delivers that content and then obtains any non-cached content from the originating server.
At the core of excellence
Words that stand the test of time
"Rolex"
With the invention of the word “Rolex” in 1908, Hans Wilsdorf did not only create a new brand. He immediately affirmed his unique vision of watchmaking and embarked on the quest for excellence that Rolex has unceasingly pursued ever since.
Having these exacting standards from the outset meant gradually incorporating all the know-how and every expertise into the manufacture, thus guaranteeing the brand’s autonomy and integrity.
With “Rolex”, Hans Wilsdorf paved the way for a unique kind of watchmaking. One in perpetual movement, capable of meeting a then burgeoning modernity and of rising above its novel challenges.
With “Rolex”, Hans Wilsdorf paved the way for a unique kind of watchmaking. One in perpetual movement, capable of meeting a then burgeoning modernity and of rising above its novel challenges. In the wake of this visionary name, other terms had to be coined to express the constant innovation which characterises the brand: “Oyster”, “Perpetual”, “Superlative Chronometer”.
Engraved on each dial, these words not only speak of water resistance, autonomy, precision or durability. They reveal what makes every Rolex Oyster Perpetual Superlative Chronometer a unique object. They embody the horological accomplishment as much as they inspire the confidence needed to overcome any challenges that may lay ahead.
"Oyster"
“Oyster”. The very word evokes water resistance. It also speaks to the unrivalled ingenuity of those who, through technical expertise, achieved the watertight qualities of the case that bears the same name and then applied them to protect the horological movements within.
In fact, “Oyster” does not only refer to watertightness but also – more broadly – to the case’s resistance to all the natural elements that may prevent a chronometer from working smoothly.
Two words – “Superlative Chronometer” – expresses our founding desire to do our utmost to continually surpass our own achievements.
To these attributes, the best is never the enemy of the good. Which is why within our manufacture is found our Superlative Control: a dedicated unit devoted to testing them all, continually and after they are completed.
With time, it has become the cornerstone of our watchmaking expertise which, with two words - “Superlative Chronometer” - expresses our founding desire to do our utmost to continually surpass our own achievements.
