This session will discuss the role of a Content Delivery Network (CDN) and its role in modern network infrastructure as it impacts IPv6 and IPv6 Extension Headers.
CDNs play a crucial role in optimizing web content delivery by reducing latency and improving performance. Here’s a breakdown of the key components
1. Edge Servers (or Cache Servers):
– These are servers distributed across various geographical locations, strategically placed closer to end-users.
– Edge servers store cached copies of web content, such as images, videos, stylesheets, scripts, and other resources, from the origin server.
– When a user requests content from a website, the CDN’s edge server closest to the user responds to the request if it has the requested content in its cache.
– Edge servers help reduce latency and improve load times because they are physically closer to users, minimizing the distance data needs to travel.
2. Origin Server:
– The origin server is the original web server where the website’s content is hosted and managed by the website owner (in your example, Facebook’s servers).
– While edge servers cache and serve content, the origin server is the authoritative source for the website’s content.
– CDNs periodically fetch or update content from the origin server to keep their caches up to date.
3. IPv6 Extension Headers:
– IPv6 Extension Headers are additional headers used in IPv6 packets to provide extra information or services. These headers are added to the standard IPv6 header to support various features or optimizations.
In this session, we will discuss the process as well as potential problems with IPv6 implementations as well as IPv6 Extension Headers.
