Section E: Client access through global request routing

An alternative request routing solution for CDNs

Another method for directing requests to NetCache appliances is the NetCache Global Request Manager (GRM) feature. GRM directs content requests from clients in a telco or an enterprise Content Delivery Network (CDN) to the NetCache appliances that are closest to the clients. GRM supports two different redirection methods:

DNS-based redirection services
L7 redirection services

For more information about using this feature for routing requests to NetCache appliances, see Chapter 11, Global Request Manager, and the Guide to Global Request Manager.
