Geographical Load Balancing

Geographical Load Balancing

VideoExchange offers an advanced geographical load balancing mechanism called Rediraptor. This unique, cutting edge technology brings many benefits over DNS and hardware load balancing solutions.

No DNS

Many CDNs use adjusted DNS servers to dynamically redirect users to nearby edge servers. DNS is transparent, but many DNS operators -like your ISP- have issues with DNS caching. When a CDN changes a route, a DNS cache can keep the wrong IP address for 24, even 48 hours. This cripples the realtime fallback, bursting and relaying feature of a CDN, leaving you with a potential blackout.

No Global Load Balancers

Some CDNs use hardware global load balancers to reroute viewers to edge servers. Although this overcomes the DNS issues, global load balancing systems are expensive and require highly trained staff. Rolling out a CDN based on GLBs could require taking parts of the network offline, migrate to new hardware and integrate the GLBs with the other CDN components.


Application Geo Load Balancing

VideoExchange uses a unique application layer geographical load balancing mechanism called Rediraptor. Redirection servers geographically load balance end users independently from third party DNS or hardware load balancers: all intelligence is built-in. With a single click you redirect traffic around the world. Changes are effective immediately. The software supports manual IP ranges, ISP ranges and Country ranges.


Automatic failover

Whenever a server, network or routing incident occurs, this delivery service is temporarily taken offline. You are alerted via the NOC page and text messages so you can restore the failed component. But do not panic: VideoExchange has already redirected users to fallback or bursting servers to guarantee maximum uptime.

Easy to use

Anyone can now operate a CDN. Match multiple edge servers to multiple regions. Offload busy servers, move traffic to idle servers. Optimize QoS. Temporarily add other edge PoP resources to a busy region. Popular assets and relays are immediately copied to the extra servers and the viewers are instantly load balanced over the servers.


Beautifully integrated

The VideoExchange Rediraption engine is beautifully integrated in the CDN software suite. Assets are immediately replicated, Uptime monitors control the redirection mechanism. The professional web dashboard shows realtime graphical load and status reports so you can immediately tune the CDN. Click and re-route traffic on the fly. No need for separate routing interfaces, no need for expensive and difficult hardware.
