Method for determining metrics of a content delivery and global traffic management network
First Claim
1. A process for determining server performance metrics in a network, comprising:
- providing a service metric probe resident on a server for determining service availability and metric measurements of types of services provided by a content delivery server;
providing a latency probe resident on a server for determining latency values for various content delivery servers within the network;
wherein the service metric probe consults a configuration file containing each DNS name in an area associated with the service metric probe and any set(s) of services associated with each DNS name;
wherein the set(s) of services include any of;
HTTP, HTTPS, FTP, streaming media, or generic SNMP;
wherein the latency probe calculates a latency value from a location of the latency probe to a client'"'"'s location; and
wherein, for a given DNS name, a DNS server uses updates to the latency values and updates to the service availability and metric measurements to determine a content delivery server to return.

Abstract
A method for determining metrics of a content delivery and global traffic management network provides service metric probes that determine the service availability and metric measurements of types of services provided by a content delivery machine. Latency probes are also provided for determining the latency of various servers within a network. Service metric probes consult a configuration file containing each DNS name in its area and the set of services. Each server in the network has a metric test associated with each service supported by the server which the service metric probes periodically performs metric tests on and records the metric test results which are periodically sent to all of the DNS servers in the network. DNS servers use the test result updates to determine the best server to return for a given DNS name. The latency probe calculates the latency from its location to a client'"'"'s location using the round trip time for sending a packet to the client to obtain the latency value for that client. The latency probe updates the DNS servers with the clients'"'"' latency data. The DNS server uses the latency test data updates to determine the closest server to a client.
