Service Node Applications
You are here: Home » Portfolio » Applications » Service Node

Service Nodes provide all operational services, including the management interface, network performance and usage reporting capabilities, and log file and audit processing functions.

The Service Nodes also provide a Web-based console interface that enables the service provider, Network Operations Center (NOC) team or content provider to interact directly with the CDN. For example, the console offers the ability to control the CDN’s network routing, geo-configuration and authentication functions.

Service Nodes can expose fully programmable and controllable network capabilities. Application programming interfaces (APIs) are available for control, request routing and delivery, reporting, publishing, acquisition, management and monitoring. These APIs enable service providers and content providers to launch services quickly, create market differentiators and simplify integration with third-party components.

For redundancy and load balancing, the Velocix CDN typically maintains at least two Service Nodes located in geographically separated locations. Each Service Node holds a copy of the master database. Additional Service Nodes in different configurations may be used around the network
