CDN Peering

Optimism your CDN by peering with our CDN Client

Content delivery networks (CDNs)

Content delivery networks (CDNs) have enabled website operators to take advantage of accelerated network speeds without compromising web performance or overburdening server resources.

More recently, techniques such as CDN peering have benefited website owners by further speeding up their sites while reducing operational expenses. This article focuses on how CDN peering improves content delivery and enhances website performance.

What are Internet Exchanges?

In order to understand CDN peering, we have to first explain where it all takes place: the Internet Exchange (IX). An IX is a physical infrastructure, usually in a well-connected data center, where Internet Service Providers (ISPs) and CDNs exchange traffic with each other as if they were part of the same network. This exchange over physical infrastructure is what’s known as “peering.”

Breaking Through Peering Policies

Our CDN peering facility can improve your current CDN. For Example, if you have Google Cache Node it needs to have some peering with other GGC to get the content which already served by other GGC node, otherwise, it will try to get it from the upstream with cost a lot.At the moment a lot of ISPs maintain multiple peering for their content. On average each ISP peering at least 3 more ISP just for GGC. In this situation, ISP has to either for NTTN transmission or maintaining own infrastructure.


This is the same as other CDN nodes. Specialty Facebook FNA costs a lot more for peering and internet bandwidth. Because in average Facebook can provide 65% of FNA requests for its cache.All keeping multiple peering is crucial for ISP at the same time it is very costly to maintain. NIX-BD has the ultimate solution to this problem.We provide free CDN peering with our clients who has their own CDN. In this type of peering not only give hug peering possibilities for CDN node but also save cost by paying just for one port.

The Benefits of a Peered System

Some of the major advantages of peering include:

  • Redundant Routing The ability to create redundant routes between traffic’s origin and destination improves reliability. Peering directly boosts the ability of a CDN network to deliver traffic dependably.
  • Reduced Transit Costs
    Peering at IXs allows CDNs to save money they would otherwise spend on transit. Because they pay a flat rate per port, CDNs effectively get maximum bandwidth for each connection without paying by amount of throughput. They can pass these savings on to customers.
  • Secured Transit
    CDNs typically scrub traffic for malicious elements (e.g., DDoS attacks) before they send it to an IX—this means that traffic coming from an IX via CDN peering is generally safer or “cleaner” than other forms of traffic.
  • Additional Burstability
    Multiple routes can help CDNs deal with burstability during peak usage times or large events. Should the primary delivery route be congested for whatever reason, CDNs can leverage peering arrangements to provide alternative routes on demand.

A Multi-Peered Strategy

as possible, it reduces latency and improves CDN performance.ISP can peer diffrent CDN from diffrent ISP without contacting and insveting in transmiion. IXs further maximize proximity by effectively providing CDNs with shortcuts between user and origin server.

Unfortunately, as not all best routes are always available from any specific IX, you can only gain access to the routes of the networks peering with you on that IX. However, by using multiple IXs for peering, CDNs can essentially access multiple shortcuts from which they can select the optimal route. It is in the best interest of a CDN to deploy their points-of-presence (PoPs) in IX-enabled data centers, since these contain optimized routes to desired regions and networks.

For example, if a ISP wanted to decrise its upstream cost for CDN in Chittagong,it could invest in infrastructure from its location to nearst ISP PoP, or alternatively, it could peering with the CDN in NIX-BD, which already has optimized routes and coverage across sevaral ISP. Although having a PoP would be the ideal means of expanding network’s presence in the region, deploying within a regional IX is an economical way for a CDN to leverage an existing, optimized local network for delivery without directly investing in it.

Adding New IXs to the Mix

By deploying peering where it matters most, CDNs can significantly improve their offering to their clients, providing them with faster, more secure transit and, overall, an improved, more optimized network.

For example, Incapsula has added 7 new IX locations over the last few months, to cover key strategic access points across the globe, including Europe, North America, and East Asia. Equally important, thanks to a new peering arrangement at the CUHK Hong Kong IX, it also offers greatly improved performance in China, where having a PoP would be less practical due to high costs and restrictive regulations.

Because CDN peering provides inherent benefits to CDN operators, CDN customers, and website visitors alike, CDNs should look to partner with strategically important data centers with IXs to offer the advantages of CDN peering to its clients.

Peering into the Future

A staple of modern content delivery, CDN peering greatly extends the benefits of a CDN to both website owners and therefore, their users as well.

Incapsula’s users, for example, now enjoy greatly improved service since the CDN provider expanded its presence in key IXs. To further enhance its offering, Incapsula continues to seek partnerships with IX-enabled data centers to further expand and improve its CDN network.
