CNAME-BASED ROUND-TRIP TIME MEASUREMENT IN A CONTENT DELIVERY NETWORK |
摘要 |
Round-trip time (RTT) for communication between an edge point of presence (POP) in a content delivery network (CDN) and a local domain name server (LDNS) is determined by resolution of a canonical name (CNAME) record. A first server in a first edge POP in a CDN receives a request to resolve a domain name from a LDNS and transmits a CNAME record including a timestamp indicating when the CNAME record was transmitted to the LDNS. The first server subsequently receives a request from the LDNS to resolve the CNAME record and determines a RTT time indicating the time needed for round-trip transmission between the LDNS and the first server based on the time when the request to resolve the CNAME request was received by the first server and the time indicated by the timestamp.
