Abstract
A routing method operative in a content delivery network (CDN) where the CDN includes a request routing mechanism for routing clients to subsets of edge servers within the CDN. According to the routing method, TCP connection data statistics are collected are edge servers located within a CDN region. The TCP connection data statistics are collected as connections are established between requesting clients and the CDN region and requests are serviced by those edge servers. Periodically, e.g., daily, the connection data statistics are provdied from the edge servers in a region back to the request routing mechanism. The TCP connection data statistics are then used by the request routing mechanism in subsequent routing decisions and, in particular, in the map generation processes. Thus, for example, the TCP connection data may be used to determine whether a given quality of service is being obtained by routing requesting clients to the CDN region. If not, the request routing mechanism generates a map that directs requesting clients away from the CDN region for a given time period or until the quality of service improves.

15. A method operative in a content delivery network request routing mechanism that generates maps for use in directing client requests to subsets of CDN servers, comprising:
-
receiving TCP connection data statistics from one or more subsets of CDN servers; and
using the TCP connection data statistics in generating a client-to-CDN server mapping. - View Dependent Claims (16, 17, 18, 20, 21, 22, 23, 24, 25)
